Overview of our technologies

Spotify Music Streamingdienst
plug & play
Together with your router, the Raumfeld Expand creates the perfect WiFi streaming environment

After an easy installation process, the Expand automatically connects directly to your WiFi router and communicates the signal without drops or interruptions to each Raumfeld device in your network. The little organizational wonder can also host media storage devices via its USB port, making it possible to stream titles from your digital library. The system's memory can index up to 200,000 titles for anytime access via the Raumfeld Controller App.

Home WiFi signals can be brought to the breaking point by many competing devices, the transmission of larger files or thick walls. The result is often dropped signals and interruptions – irritating hindrances to the enjoyment of your music. The Raumfeld Expand puts your music streams back in the fast lane by creating an autonomous WiFi signal exclusively for your Raumfeld system.

Lossless audio tracks can place a large burden on home WiFi systems which often host a range of other devices from smartphones and tablets to game consoles. To facilitate the best multi-room experience with top quality digital music files, the Raumfeld Expand create a dedicated WiFi network for your music. The system can manage an incredible 200,000 tracks for instant access to your favourites, playlists and other personal settings across a huge range of music via the Raumfeld App.

Autonomous, not exclusive

In addition, the Expand is equipped with a USB port to which even large external hard drives can be directly attached. NAS and DLNA/UPnP media servers containing compatible music files can also be accessed by the system.

Audio streaming without frontiers

Lossless audio presents a challenge to audio streaming because of the large volumes of data involved. In order to cope with bigger quantities of data within a limited broadband, many manufacturers of streaming products compromise the signal. In other words, the lossless files that you select from a service like TIDAL or your private music library is not what is played back. Raumfeld, however, respects the integrity of all music files and does not compress them for easier streaming. The Expand creates the wireless infrastructure needed for streaming the best quality audio without compromise.

Equipped with two adjustable antennas for incredibly reliable and fast transmission, the Expand is perfect for situations where a weak router, thick walls or the use of many streaming devices at once hinders the smooth streaming of larger files. The external placement of the antennas extends the range of the wireless network for music enjoyment without drops or disruptions from multiple Raumfeld players in any room in your home.

State-of-the-art streaming, down-to-earth setup

Integrating the Expand into your Raumfeld system requires absolutely no prior technical knowledge. Simply connect the device to your WiFi router via the included Ethernet cable and let the system do the rest. The Expand automatically recognizes all Raumfeld players already connected to your router. Additional Raumfeld players can be added to the network with the simple press of a button. A single, discreet LED light keeps the user updated as to the device’s status.

Thanks to its compact dimensions and integrated wall mounts, the Expand is easy to integrate into your home.

A small, modular powerhouse

A little speaker that makes a very big impression. A power connection and Wi-Fi access are enough for this little guy to fill even medium size rooms with rich, high-definition sound. A free app allows you to access music from your own private collection as well as streaming services and Internet radio. Alternately, 4 preset buttons allow you to get your favourite streams of music started right away. A volume regulator and on/off switch are also included for directly controlling the system.

The little One S works with a wide range of streaming services as well as your own music collection stored on USB or DLNA enabled devices. You can also send music stored on your smartphone or tablet directly, wirelessly, and losslessly to the One S.

The little One S is jam-packed with high-end acoustic and streaming hardware including:
  • A 2-way coaxial system consisting of a 100 mm midbass driver with forward placed 20 mm tweeter. Not only does this arrangement allow more drivers to be placed in a smaller space, it approximates a point source for an acoustically superior result. The same system used in our Stereo Cubes has garnered the system wide-spread praise for its powerful, clear and detailed sound.
  • A long throw 100 mm midrange driver allows the One S to produce amazingly deep, rich and responsive bass.
  • Side-mounted 80 mm passive radiators give the system an incredible 45 Hz low end.
  • A digital signal processor using a sophisticated equalizer to eliminate any resonances or gaps in the bass range for a nearly perfectly linear frequency response and true-to-source playback. Equalizer presets adjust the sound for the kitchen, bathroom and living room for an optimal sound.

Thanks to a low noise 50 watt class D amplifier, the One S produces incredibly high, distortion-free levels in even larger rooms.

If the One S is combined with other Raumfeld devices, the entire multi-room system can be centrally controlled with the Raumfeld App as well.

Built to last

An aluminium cover adorns the front of the One S. The control buttons are made from pleasantly soft silicone that are perfect for use in a messy environment like the kitchen as it's easy to wipe off a bit of Nutella or jam. Robust fabric covers protect the drivers and rubber rings on the bottom guarantee secure placement.

The One S can be easily wall mounted

Integrated keyhole brackets make it easy to mount the system on a wall. Flexible wall mounts are also available as additional accessories.

Setting up the system is easy and no other devices are needed to make i t work other than a Wi-Fi router and smartphone/tablet.
The Raumfeld Soundbar effortlessly masters two sonic realms: Home cinema and music. The stunning lacquered wood and brushed aluminium wireless system uses Wellenfeld Technology to produce an astonishingly broad soundstage.

The result is immersive sound no matter where you sit in the room. A powerful active subwoofer in an innovative flat design receives audio signals from the Soundbar in lossless sound quality for deep and punchy bass with movies, games and music. Its discreet design allows the sub to be placed anywhere in the room – even under a sofa!

Integrated Wi-Fi streaming technology makes it possible to stream a range of digital music formats including lossless files to the system and play them back in hi-fi sound quality. With the free Raumfeld Controller App for Android and iOS, it’s easy to select music from various streaming providers, internet radio and your own collection. In addition, the Raumfeld Soundbar works seamlessly with other Raumfeld devices for the ultimate multi-room audio experience. 

The living room of the future: The Raumfeld Soundbar + HD TV

The Raumfeld Soundbar is perfect for use in interiors that either have no space for a traditional 5.1 home theatre system or where many audio components would spoil the overall look. Simply connect the attractive and sleekly styled Soundbar to your HD TV via HDMI cable and follow the push-button pairing procedure for the wireless sub. You won’t need any additional devices such as an amplifier or A/V receiver. 

The Soundbar should be centred in front of your television set, either mounted on the wall or placed on the included table stand beneath the display.

Included connections: HDMI with ARC/CDC, digital and stereo RCA

A variety of connections on the Raumfeld Soundbar offer you maximum flexibility. HDMI 1.4 with Audio Return Channel (ARC) means that the HDMI connection functions either as an input or output channel depending on the desired playback. The Soundbar also supports CEC, a widely adopted standard for centrally controlling multiple devices. If your television also supports CEC, you can use your TV remote to control the Raumfeld Soundbar as well. Alternately, you can use the stylish brushed aluminium remote that comes with the system for controlling all essential functions from a distance of up to 10 meters. For even faster access to your favourite streams, there are preset buttons on the Soundbar itself. And, of course, there is the free app for Android and iOS smartphones and tablets. In short, the Raumfeld Soundbar not only offers a maximum of connection options, you’ll enjoy incredible flexibility when it comes to controlling the system.

Please note: To be able to use the Raumfeld Soundbar via the HDMI-ARC/CEC connection, you must first ensure that your television supports HDMI 1.4 with Audio Return Channel.

Alternately, you can connect your television to your Raumfeld system via digital optical cable. 

Wellenfeld sound technology engineered in Berlin

Our sound engineers developed Wellenfeld Technology for generating a surround sound experience from a compact enclosure. Using a lightning-fast DSP chip and sophisticated algorithm, the Raumfeld Soundbar’s 6 drivers are expertly guided in the creation of an immersive, 3-dimensional sound image.

Unlike virtual surround technologies, the algorithm used for the Raumfeld Soundbar doesn't rely on psychoacoustics. Instead, the 6 drivers to work together in such a way that the entire room is actually filled with 3D sound that extends far beyond the size of the system for a thrilling home cinema experience anywhere you sit.

Music streaming in hi-fi sound quality? Raumfeld makes it possible.

The Raumfeld Soundbar’s ability to quickly and easily connect to your home Wi-Fi gives you access to a world of music – at the tap of a finger.

As part of the Raumfeld system, the Soundbar not only lets you listen to music via your home Wi-Fi, it works seamlessly with all other Raumfeld devices. That means that not only can you use the Soundbar for all your music streaming needs, additional Raumfeld devices can be added to your home network for multi-room streaming. The Soundbar and its active subwoofer can play in perfect sync with other Raumfeld devices in the same network. You can also play different tracks on each device for multicast streaming with easy, centralised controls thanks to the Raumfeld App.

A complete stereo system – and then some

Amplifier, tuner, CD player and loudspeaker: The Raumfeld Soundbar does the work of all of these devices and more. With a combined 280 watts at their disposal, the Soundbar and Subwoofer have enough power to fill even larger rooms with thrilling movie sound and music.

Advanced acoustic technology transforms your living room into a sonic oasis

Many speakers have a great sound – as long as you sit in exactly the right spot, commonly referred to as the “sweet spot.” The problem is that this space isn’t usually big enough to include a larger group of friends or a whole family. Some people inevitably get relegated to the “cheap seats.” The Raumfeld Soundbar was engineered to allow the greatest number of people to enjoy cinema sound and music as it was meant to be heard. That’s why our acoustic engineers developed a special playback algorithm capable of expanding the listening zone well beyond the physical dimenions of the device.

Tap into the possibilities of streaming with the Raumfeld Controller App

The free Raumfeld Controller App for Android and iOS mobile devices allows you to effortlessly select music from various sources and assign the streams to Raumfeld devices in your home.  If you have more than one Raumfeld device, you can assign speakers to individual listening zones. Control the volume and equalizer levels on each speaker or zone, create playlists and browse through the immense music libraries of Raumfeld’s streaming partners or your own digital collection.
Streaming WiFi Raumfeld Soundbar Subwoofer Bass
The Raumfeld Soundbar & Raumfeld Subwoofer: Perfect harmony
The Raumfeld Soundbar’s integrated class D amplifier powers 6 x 70 mm drivers with 150 watts for sound pressure levels up to 102 dB.

The Soundbar’s dynamic, enveloping sound is supported by the Raumfeld Subwoofer. Like the Soundbar, the active sub is also equipped with a class D amplifier for firing its 3 bass drivers with 200 watts. A 35 Hz low end ensures that movie soundtracks can be felt as well as heard. The use of 3 smaller high-excursion drivers instead of a single large woofer makes it possible to give the Subwoofer its compact design. Not your typical boxy sub, the Raumfeld Subwoofer can be slid under a sofa in a horizontal position or even hung vertically behind a sideboard. This amazing advantage comes at no cost to performance. Deep and punchy bass that is never “boomy” or muddy is what you can expect.
Wi-Fi network player
The Teufel Connector is a high-performance network audio player that uses Wi-Fi to stream even high resolution files like FLAC and WAV. Attached to your stereo or home cinema system, the Connector gives you access to a world of music from the cloud or your own home network. Stream from popular music services like Spotify and SoundCloud as well as thousands of web radio stations or the music stored on your smartphone or NAS. The free Teufel Raumfeld app makes it easy to control playback, set favourites and discover new artists.

"It produces a very serious sound for such a small enclosure."
On-Mag 20.03.2017
"The two integrated Class D amps succeed in giving an unexpected density to the sound of the Raumfeld One S. This also has to do with the quality of the speakers. The Raumfeld One S is equipped with a coaxial transducer on its front side. This consists of a dedicated tweeter with a 25 mm aluminum dome and a 9 cm diameter woofer with a polypropylene membrane. It is supported at the bottom of the spectrum by two passive radiators with flat, 9.5 x 8 cm rectangular membranes, also aluminum, it would seem. It produces a very serious sound for such a small enclosure."

"With a lively and at the same time pleasant tone, there can be no doubt as to Raumfeld’s ambition to be known as the most musical of all the streaming brands."
AreaDVD 05.12.2014
"An excellent sense of spaciousness is created. If one isn’t looking at the speaker and isn’t aware of how small it is, it would be easy to believe that a larger device is playing.“

"The Raumfeld One S is extraordinarily compact and extremely multifaceted. Access to many streaming services as well as PCs, servers and data on smartphones and tablets open countless use scenarios. Initial setup, [...] proves itself to be truly short and simple. Once the One S is connected to a network, playback is convenient and reliable. With a lively and at the same time pleasant tone, there can be no doubt as to Raumfeld’s ambition to be known as the most musical of all the streaming brands. Hi-Res audio files can be easily played back by the One S. For its size, the One S also has good level stability. On the balance, an exception gateway to the Raumfeld world.”

"… the Raumfeld system enjoys great popularity in the multi-room segment, especially for all those for whom nothing less than hi-fi will do.“
SFT Magazin 11/2015
*The score refers to the Raumfeld System. The following devices were tested: The Once S, the Stereo Cubes and the Stereo M

"… the Raumfeld system enjoys great popularity in the multi-room segment, especially for all those for whom nothing less than hi-fi will do.“

"All of the components are well made. The solid metal and wood cabinet conveys a luxurious and premium image.”

"As soon as the multi-room system was set up and supplied with music, the sound of the individual components won us over […] completely. The Raumfeld speakers played with a great sense of openness and had a very fine sound. Above all, the Stereo M fully delivered on hi-fi expectations and gave a spirited performance that had a lot of dynamics at its disposal. This also applied to the smaller loudspeakers in the set which sounded very balanced and offered a lot of power for their size.”

"The Raumfeld One S is a great-sounding Wi-Fi speaker with bass response that could shame much larger speakers"
CNET 19.11.2015
"The Raumfeld One S is a great-sounding Wi-Fi speaker with bass response that could shame much larger speakers, and support for 24-bit/192 kHz files. The speaker is compact, and its water-resistance makes it a great choice for bathrooms and kitchens."

"Sonos has been the leader in whole-home music streaming industry for a long time, long enough to see numerous competitors fall by the wayside. In the last few years at least a dozen new players have emerged, including DTS' PlayFi, Bose's SoundTouch, Denon's HEOS and Yamaha's MusicCast. Now it's time to add to the mix Raumfeld, a German brand currently available in the UK and coming to the US soon.

While the company's line of wireless products gets pricey very quickly -- the Stereo L is over $2,000 -- the entry-level Raumfeld One S, which is $249 or £199, offers excellent sound quality and a robust design. Compared against both Denon's HEOS 1 and the Sonos Play:1, the Raumfeld comes out on top in terms of sonics and is the only one that supports higher-than-CD-quality music."

"[C]onfigured as a stereo set, it transforms into a musical treasure trove..."
audisseus 11.2015
"If a single Raumfeld One S already sounded larger than it actually looks, two of them revealed an entirely unanticipated, positively mature-seeming level. [...] In short, the Raumfeld One S is a substantial-sounding everyday companion; configured as a stereo set, it becomes a musical treasure trove that leaves hardly anything to be desired.”

"With solid build quality and style the Raumfeld One S wireless speaker should look at home in almost any setting and comes with surprisingly punchy audio for such a small cube."
Trusted Reviews 30.04.2015

Raumfeld One S – Sound Quality

"The Raumfeld One S is an impressive-sounding speaker, especially when you consider its diminutive size. In some ways it’s even better than the current leader of the pack, the Sonos Play:1.

It uses the same two-way coaxial system as the excellent Raumfeld Stereo Cubes we reviewed recently. The 90mm mid-range driver, 25mm tweeter and two woofers provide a solid sound you’d expect to hear coming from something much, much bigger.

We don’t expect hi-fi-quality sound from a speaker this size and price, but music is clear, detailed and packs an impressive punch at higher levels. The One S can certainly fill a medium-sized room with rich, distortion-free sound.

Where the Raumfeld falls a little short is the low-end. Bass is a touch limited, even more so than the smaller Sonos Play:1. Unlike the cheaper TrustedReviews Awards-winning Samsung M3, however, the sound never gets muddied on bass-heavy tracks. It remains balanced and clear throughout, if a little weak. Listening to some Tricky and hip-hop albums lacked the low-end oomph that brings that genre to life. At top levels treble can be a little harsh too, but the midrange packs plenty of detail and clarity.

These issues are minor – most people not obsessed with audio fidelity will be thoroughly impressed with the power and sound quality of Raumfeld’s little marvel.

Overall we ever so slightly prefer the One S to the Sonos and Samsung, both in terms of a balanced sound and top volume level. If you’re into bass-heavy tracks, though, the Sonos or Samsung may be better bets."

"These premium speakers pump out incredible sound and can stream either DAB radio stations or your very own music over your home Wi-Fi network."
Recombu 24.03.2015

We review the Raumfeld One S, a seriously slick and durable multi-purpose music machine for your bathroom or kitchen.

"Raumfeld is hoping to fill your entire house with its comprehensive range of multi-room music streaming devices, and now that we’ve seen/heard them in action, we’re completely sold."

"These premium speakers pump out incredible sound and can stream either DAB radio stations or your very own music over your home Wi-Fi network. Raumfeld’s One S is the bathroom/kitchen model, toughened just enough to make it resistant to water splashes without ruining the consistent, premium aesthetics that dominate the range.

The One S sports an almost-cube build with a mesh front and black or white frame. The design is stunning and also plays well with pretty much any decor. A silicon control panel on top can be used to switch between four pre-set DAB radio stations or change volume, while the two dinky lights on the front show when the speaker is turned on and connected to Wi-Fi."

“With its rounded corners and softly flowing form, the One S has a very sleek look which I really appreciate since it doesn’t seem intrusive. It simply fits comfortably into the overall décor, no matter where it’s placed."

"Raumfeld promises a quick and easy setup with its products […] it really is this easy.”


"[...] I’m really enthusiastic about Raumfeld speakers and would like to have one in every room of my apartment. The design is very pleasant and, with its simplicity, goes with every interior, but without allowing the loudspeakers to “disappear” [...]“

“Operating the system is really incredibly easy. After opening the app, start music playback and just enjoy.”

“I found the ability to listen to the same music in multiple rooms in particular to be a lot of fun [...]“

“I was also satisfied with the number of possible music sources. Access to one’s own music on the computer, connecting pen drives or another devices via line-in, radio stations and, of course, well-known streaming services – what more could one ask for?”

"I only have positive things to report regarding the loudspeaker’s sound. I like it; they sound warm and full and it’s possible to adjust the sound to one’s own preferences regarding treble, bass and the midrange.

The Raumfeld loudspeakers are really a well thought out concept that, from the unboxing to the setup and daily use, are simply a delight.”

"The material mix of brushed aluminium on the front and silicone on the control buttons - which renders them water repellent - and matte lacquer on the rest of the loudspeaker makes it not only a visual treat, but gives it a robust and high-end end appearance.

First impressions

"The white loudspeaker looks really good. The matte synthetic enclosure is the product of high-quality workmanship and comes across as very modern and minimalistic. It fit wonderfully into the overall look of our living room. “

"I would describe the sound quality as impressive – in every respect. I was blown away by the first listening session. After all, that this small box with the dimensions 11 x 18 x 13 centimeters delivers such a powerful and yet clean sound is simply amazing.“

"The bass has incredible power, the highs sound clean and don’t distort at even high volume levels. The One S had no problem filling our 30 square meter living room with sound, and if I turn up the volume any more, the neighbours will no doubt be at my door in seconds.”

"So small and yet so big: With the One S, Raumfeld has a very good entry level device to its line that, with a price tag of just 250 EUR, is very attractive. The sound is phenomenal for the size and the system can be easily controlled with the app.”

"The Raumfeld newby reproduces voices clearly and without distortion. The speaker even overflows with dynamics with quick concert sequences  […] and doesn’t doesn’t lose its rhythm.”

"The One S puts across a very mature performance – neither overly playful nor was it designed as a compromise. Naturally, the bass can’t compete against larger loudspeakers.

"As one has come to expect from Raumfeld, the One S is a technologically exceptional device. The moment you touch it, it becomes clear that you're dealing with a quality product and not another plastic box masquerading as a loudspeaker. The enclosure is well made, the design and the entire device, minimalistic. And for exactly this reason, the One S can be integrated into practically every living or working environment without making itself conspicuous [...].“

"The sound quality is best described by the adjective 'impressive' and that in every respect. After turning the device on, one is immediately blown away by the fact that a speaker with the dimensions 11 x 18 x 13 centimeters can deliver this sort of powerful and yet clean sound. “

"Once you recover from the shock and listen more closely, you notice that Raumfeld really does its job. The One S contains a tweeter, a midbass and two bass drivers. All-in-all, the ensemble delivers maximum sound pressure up to 101dB/1m – enough to fill even full-sized living rooms with sound. A 50 watt bi-amping amplifier ensures high volumes along with dynamic bass performance.”

"I really love the way all kinds of info and settings are accessible from the main screen."

Setting up

"Setup is really easy: start up the Raumfeld app and follow the instructions on screen. When that routine is finished you add one or more network shares that hold your music. You just select from a list of (possible) sources. Shown are computers that hold shared volumes or DLNA services."

The app

"Pressing the play button next to her name starts playing all her albums but you can also select one album or one track. Along the top of this window you can choose for sorting on album, genres, favorites, composers, recently added, by folder and on track. Tapping the left top corner of the album art shows the playlist, tap the center and the technical data of the music file are showed. Under the transport functions music zones can be activated, grouped and deactivated. The volume knob in the lower right corner also has a fold out menu for tone and balance control. Other sources are selected in the top row, where TuneIn offers plenty internet radio stations and subscription services as Tidal, WIMP, Spotify and Napster by Rhapsody. You can select the line input on any Raumfeld device in your system and play it on the same or any other Raumfeld device. I once said that any remote app for music players works just as fine, you just have to get used to it. The Raumfeld app proved me wrong. I really love the way all kinds of info and settings are accessible from the main screen. And that's even more than I have described here. The app isn’t as solidly robust as that of Sonos or Bluesound, it for instance jumps back to the home screen after short connection losses that occur from time to time. That doesn’t stop me from calling it my personal favorite but please do notice the word personal, for judging user interfaces always is a personal matter."
To sum up
"Comparison with the Squeezebox might seem odd, but it’s still popular despite being out of production for years and there still is an active second hand market. Replacing it with the Connector 2 might be interesting if you have a large music collection or if you want to play 24 bit 192 kHz files. The Logitech Media Server that provides Logitech devices with music is rather slow with large music collections, which is not the case with the Connector. Compared to the Sonos Connect it offers far more memory for storing the music catalogue and 24 bit 192 kHz playback at half the price. So if you have a stereo at or below the quality of my Set 3, the Teufel Raumfeld Connector 2 offers decent quality at a very low price."

“Teufel sells its miniature network player for a mere 200 Euros. In exchange, one gets an astonishing array of music possibilities as well as an alluring and extensive introduction into the world of Raumfeld. One namely has the ability to use the Connector 2 in combination with other network players from this manufacturer to build a multiroom connection [...] At first glance, the newcomer appears to be hardly different from its predecessor. The enclosure, however, is compacter. The reason for this is quickly ascertained: The WLAN antenna which was located on the back of the original Connector has been discreetly relocated in the interior of the enclosure. This change earns the new model high marks for style.”

“The basic structure of the network player hasn’t been changed by Teufel: The streamer plays music from UPnP or DLNA certified network servers along with NAS drives as well as the music library from any PC with Windows. It’s even capable of supporting sound formats [...] from USB storage devices connected to the back. Those who require more can tune in to tens of thousands of internet radio stations via the TuneIn service or can log in to his simfy or Napster account or make use of the analogue input. Should one possess more than one Raumfeld device, these signals can be streamed into other rooms. Unlike that first Connector, the new model can process a full 192 kilohertz.”

 "The Connector2 can be integrated into networks with or without a cable. The cable connection is very simple. One simply inserts the appropriate network cable into the corresponding interface on the device and the Connector will be connected to the home network. [...]
If the Connector is connected to the Wi-Fi, it must be added as a ‘new room.’ For the setup, an Ethernet cable must be attached to the Connector, following which the Raumfeld App can be added. The router password must also be entered. The automated configuration for the Wi-Fi will follow, after which the LAN cable can be disconnected and the Connector2 will be wirelessly connected to the network.”

"The Connector plays MP3, WMA, WAV, AAC, FLAC, OGG and Apple Lossless. A 192 kHz sampling rate is supported which makes the Connector2 compatible with high-resolution audio files. [...] The Connector creates an impressive-sounding playback with 192 kHz FLAC pieces such as Wolfgang Amadeus Mozart’s violin concert (SL Recording) in D minor. The details, clarity, and dimensionality are highly pronounced. The violins as the primary carriers of the song sound brilliant without having too sharp a tone. Even the complex piece ‘La Mer’ by Claude Debussy was captured in a very multifaceted way, including the many small dynamic differences which were accurately produced. The 96 kHz FLAC piece ‘Stop This World’ by Diana Krall has a lively, emphatic quality with a taut bass that is well differentiated in the listening room. Dianas’ voice has a smokey undertone, giving it a charismatic quality.

Depending on how good the D/A converter in one’s amplifier/receiver is, it’s possible to access the digital connection if this is available. In any case, we recommend a listening test before deciding on an analog or digital connection. Especially with older or inexpensive amplifiers/receivers, the use of the Connector’s very good D/A converter can be the better option. Even when bitstreams are transmitted from Internet radio platforms (TuneIn), the Connector ensures a lively, dimensionally rich sound with a high degree of clarity. The reliability of the transmission is very high. It doesn’t matter whether it’s connected to a LAN or Wi-Fi – interruptions are almost never discerned. This is true for the reproduction of Internet music streams as well as sound files from PCs or servers.”


"All told, Teufel offers a highly polished solution that can make hifi systems and older surround receivers fit for the era of modern media. With the exception of Spotify, all relevant music services are integrated and it’s easy to add music resources from PCs, servers, and USB storage devices. Playlists are quickly set up and can then be easily accessed. A free app enables simple handling so that even less experienced users can quickly and easily figure it out. The Connector2 can be connected to the network either with a cable or wirelessly. No Wi-Fi antenna intrudes upon the compact enclosure. The sound that the very compact and therefore easily accommodated Connector makes available is excellent and corresponds with Raumfeld’s claim to offer first-class streaming quality.

Flexible to use and strong on sound – the ultra compact Connector2 delivers on all counts."

“The streaming division of Teufel Audio has been around for just three years. Their product range extends from streaming loudspeakers and small routers to NAS systems and controllers – in other words, the whole streaming program. The new Connector 2 extends the existing hi-fi range to include smart streaming abilities.”

“The Berlin loudspeaker manufacturers and home cinema experts Teufel acquired a highly competent team with Raumfeld GmbH [...]. Since then, smart active speakers with integrated streaming and components that enable an expanded and user-friendly music network have been produced. One thing should be made clear: With respect to network stability, Raumfeld components are ahead of the pack.”

Help regarding this product
I have more than one Raumfeld device and would like to listen to Spotify in the multiroom mode. How does this work?
First check that you have a valid subscription for Spotify Premium. You will also need to have both the Raumfeld and Spotify apps installed on your smart device. Now, open the Raumfeld App and tap on the Spotify symbol under music services or on the home screen. Activate the multiroom mode for Spotify by sliding the switch to the “on” position. Once activated, you can select the rooms where you wish to stream music. These will appear in the Spotify App as Raumfeld Zones.
I want my Raumfeld speakers to use less energy when no stream is playing. Does Raumeld offer an automatic standby mode?
It’s possible to activate a standby mode with all Raumfeld speakers starting with generation 2. To activate this mode, go to the room settings in the app, then select the speaker you would like to configure and “automatically activate standby” from the dropdown menu. Here you will be able to activate “ON” or “Off.” The device’s energy usage in the standby mode will be even lower than the standards mandated by the EU.
Is it possible to reinstall the firmware of a Raumfeld device ("flashing")?
Should one of your Raumeld devices no longer react even after you've disconnected the power and restarted the device, you may reinstall the device's firmware and thereby reset it to factory defaults.

Please note that when reinstalling the firmware all device settings are lost. 

Here you will find advice on reinstalling the firmware of the following devices:

Can I connect USB storage to the Raumfeld system?
Music that is stored on USB sticks or USB hard disks will be added to your Raumfeld music collection if the storage device is connected to the host of your Raumfeld system.In a system with a Raumfeld Base the Base is the host. In a system without a Raumfeld Base you may set the host device yourself under Settings > Network > Host Configuration.
USB storage devices that are connected to another Raumfeld device than the host can not be integrated as music resources.Please also note that apart from USB sticks, first-generation Speakers, Ones or Connectors support usb hard disks with their own power supply only. This constraint does not apply to second-generation devices, e.g. Connector 2.

Supported Formats
USB storage devices with the following formats are supported:
  • FAT16 / FAT32
  • NTFS
  • HFS / HFS +
  • EXT2 / EXT 3 / EXT 4
In a few cases problems with USB 1.0 storage has been reported. We therefore suggest to use USB 2.0.
Can I use my iTunes library with Raumfeld?
You may use your iTunes music and playlists in the Raumfeld system. There are several alternatives to do this:

All systems:

Sharing of the iTunes music and playlists on a network share

Your iTunes music and playlists remain on your computer and Raumfeld accesses the files via the network. Please note that they are only available if the computer is turned on.

Alternative methods for systems with a Raumfeld Base:

Copying of iTunes music and playlists onto the Raumfeld Base
Your iTunes music and playlists correspond to the status in iTunes at the time of copying onto the Raumfeld Base. However, you have the option to copy the data again at a later time in order to thereby update it.

Use of the Raumfeld Base as the iTunes Media folder location
Your music library is centrally stored on the Raumfeld Base and iTunes accesses it via the network. Provided that your computer is connected to the home network you will feel no difference to using your iTunes with a locally-stored media library. This method is therefore particularly suitable for desktop computers. Find out more: https://manual.teufel.de/en/online-manual-music-resources.html
Can I listen to the radio on my Raumfeld System?
Yes, via the online service "TuneIn".
Raumfeld offers an equalizer function but I can’t find it in the app. How can I access the equalizer?
The Raumfeld Equalizer has been given a different location within the app. You can now access the sound settings directly via the volume menu.
Does Raumfeld support gapless playback?
Since version 1.2 Raumfeld plays back music gaplessly. That means there is no audible pause between two titles what isn't included into the original recording.
What is special about Teufel Streaming (Raumfeld) compared other multi-room audio products?
Teufel Streaming offers outstanding sound quality. Thanks to roots in the professional audio sector, Teufel Streaming prioritises sound quality above all else. That becomes manifest in the whole audio processing chain - from the usage of high-class audio components to the point of the perfect adjustment of all components to each other.
Teufel Streaming is easy to use, thanks to the development by usability experts and constant consultation with users. Whatever function you want to use you will always reach your goal within a few steps.
Teufel Streaming is complete. Teufel Streaming is a complete multi-room audio system. Third party devices (speaker, data storage, computers) are not necessary in order to use Teufel Streaming.
Which music file formats are supported by Raumfeld?
Supported audio formats: MP3, WAV, Flac, Ogg Vorbis, ASF, WMA*, M4A containing AAC or Apple Lossless
Compatible playlist formats: WPL, M3U, PLS, iTunes playlists
Please note that there may be structural bottlenecks in the Wi-Fi transmission of lossless formats. If your music library consists mainly of very large FLAC, Apple Lossless or WAV files, we recommend connecting your Teufel Streaming host device via network cable or using the optional Raumfeld Expand. 
*Currently only WMA files encoded with the regular WMA codec are supported. WMA Lossless, WMA Pro and WMA Voice are not supported.
Which speaker is on the left, which one on the right?
In order to allow you to position your speakers perfectly within your room, you can choose which of the two speakers you want to control with the left stereo signal, and which with the right. Find out more: https://manual.teufel.de/en/online-manual-setup-configuring-of-devices.html
How can I add album artwork to my music library?
There are different ways to add album artwork to your music library in order to see them on your Teufel Controller:
  • Embed the artwork within the music file
  • Save the artwork in the album's folder
Also, if your Teufel Streaming system is connected to the Internet, missing artwork will be added automatically (if they can be found on the online music service Last.fm).

Embedding the artwork in the music file

Most media players and special "tagging" applications can be used to embed album artwork in music files.

Saving the cover in the album's folder

If all tracks of an album are stored in their own folder you can simply move the artwork image file to that folder. The Teufel Streaming system will then associate the image file with the album.

Supported image formats, size and resolution

We recommend the usage of JPEG images (300x300 pixels, 72 dpi).

Of course, other image formats (PNG, GIF) and sizes are also supported.
How can I connect a CD or MP3 player?
Raumfeld playback devices come with an analogue audio input (cinch) for connecting your CD or MP3 player, iPhones, iPods etc. The input signal may be played back directly via the connected Raumfeld device, or you may stream the signal to other rooms.

Most MP3 players may additionally be connected to the Raumfeld Base via USB. Should your system not contain a Raumfeld Base you may connect the MP3 player via USB to your Speaker or Connector. 

Please note: As the music library on iPods and iPhones is not directly accessible for third party manufacturers, iPods and iPhones can only be connected via their analogue audio output.
How can I delete imported playlists?
In order to delete imported playlists from the music database you have to delete the corresponding playlist file on the music resource:
  • Use your file management application to navigate to the folder that contains the playlists file (.wpl, .m3u, .pls oder iTunes Music Library.xml). It doesn't matter if it is stored on the Raumfeld Base, USB storage or a network share.
  • Delete the playlist file
If the playlist file was stored on your Raumfeld Base or an attached USB storage your music collection will be updated automatically within a few seconds. Hence, the playlist will no longer be displayed under Playlists > My Music.

If the playlist file was stored on a network share, you have to manually initiate a rescan of the network share in order to see the changes in Playlists > Imported. Find out more: https://manual.teufel.de/en/online-manual-scanning-of-music-resources.html.
How can I import my existing playlists into the Raumfeld system?
The following playlist formats are imported into the Raumfeld system and displayed under Playlists > Imported:
  • iTunes Playlists (iTunes Music Library.xml)
  • Windows Playlists (*.wpl)
  • M3U Playlists (*.m3u)
  • PLS Playlists (*.pls)
In order to import your existing playlists into the Raumfeld system, simply save the corresponding playlist files on a USB storage device, a shared folder or the Raumfeld Base (see also music resources).
How synchronous is the playback of multiple players?
When only Raumfeld devices are grouped in a music zone, they offer perfect synchronisation (less than 5-millisecond phase displacement).  This means that you can use multiple speakers in one room without hearing an echo or hall effect.

Third party UPnP/AV internet radios that are operated with Raumfeld may have less than perfect synchronisation. When positioned in different rooms, however, there is still no echo to be heard.
How do I tag my music collection? Which tagging formats are supported?
To get relevant title information such as the artist or album name of a title, the media server uses the metadata - or tags - of your music files. So in order to browse your music collection by artist, album, or genre, the music files must be tagged accordingly. You can find out more about how to do so at: https://manual.teufel.de/en/faq.html?produkt=1913#faq9
What is the maximum number of rooms that can be filled with sound?
This strongly depends on the Wi-Fi performance. If you have three or more speakers, you should connect the host to your router using an Ethernet cable.
I want to save a Chromecast stream on the direct selection keys (not applicable to all devices). How can I do this?
For technical reasons, it is not possible to store Chromecast streams on the direct selection keys.
One advantage of streaming with Chromecast is that you can continue to use your usual music app. How can I check if my apps already support Chromecast?
Chromecast built-in already supports 100+ apps, including many popular music services, and works with the Chrome browser. You’ll find an exact overview of all Cast-enabled apps here:


Tip: If you didn’t find your app on this list, you may want to contact the provider directly and ask when Chromecast will be integrated. In the meantime, you should have no trouble finding an alternative from the large selection of Chromecast-enabled apps.
Ich habe eine eigene Sammlung von Musik mit hoher Qualität und möchte diese über eine Chromecast unterstützende Musik-App abspielen. Wieso werden mir die Titel nicht anzeigt?
Chromecast built-in can stream CD-quality audio up to 48 kHz. If your collection has a higher sampling rate, you can stream it via the Teufel Raumfeld App.
I also want to use Chromecast's multi-room function and stream to multiple speakers at the same time. How can I do this?
Multi-room streaming is also possible with Chromecast. To do this, create a grouping of speakers within the free Google Home app which you will need to install on your smart device. You can name created groups on the app.

After you create and name your groups, they will appear alongside individual Cast-enabled speakers in your music app.

Google Home App (Play Store)

App Store iOS
I use the Spotify app to stream to my speakers. I don't see any or not all of my Chromecast speakers under "Available devices". What could be the reason?
In order to stream with Chromecast built-in, you’ll need the most recent version of the Spotify App. We recommend updating your app and trying again. Please note that you will also require a Spotify premium account in order to stream to your speakers.
I like watching YouTube videos. Can I now use Chromecast to wirelessly output the sound of YouTube videos while watching them?
The wireless transmission of audio content from YouTube is possible with the following:

1: A computer running on either the Windows 10/8.1/8/7 32 bit, Mac OS X 10.9 (or higher) or Linux operating systems.

2: A current version of the Chrome browser. You can download the most recent version here:

3: The Chromecast built-in extension for the Chrome browser (if not already integrated)

4: A least one Teufel Streaming device with Chromecast built-in registered to the same Wi-Fi network as the computer using the Chrome browser

Begin a YouTube video. Select the “streaming” option from the “more” menu in the Chrome browser. This will call up a menu displaying all Teufel Streaming devices in the network that can play back the audio.

  • The video displayed on your screen and audio from your speaker may not be in perfect sync.
  • It is not currently possible to directly cast audio from the YouTube app for iOS or Android.

Tip for Android users: You can stream audio from the YouTube app on Android devices using the Android mirroring function. To do so, simply complete the following steps:

Step 1: Install the “Google Home App” and open the menu on the left side.

Step 2: Tap on the option “Screen/Audio streaming” and select the Teufel Streaming device you wish to cast audio to. An active connection will be displayed in your smartphone’s status bar.

Unfortunately, this option is not currently available for smart devices operating on iOS systems.

Step 3: Switch back to the YouTube App and start a video as you normally would. The audio will play from the Teufel Streaming device you just selected.

Please note that the picture and audio may not be in perfect sync.
Ich streame Musik direkt aus dem Chrome-Browser. Die Wiedergabe ist jedoch manchmal verzerrt oder setzt kurz aus. Was kann ich dagegen machen?
The most frequent cause of distortion and drops in playback is insufficiently fast data transfers from the PC to the WiFi speaker. Data transfer rates can be affected by the WiFi router and the internet connection. We recommend enhancing the performance by increasing the WiFi signal strength in the vicinity of your PC and speaker.
Ich verfüge über eine sehr große eigene Musiksammlung. Seit ich das Update mit Chromecast built-in durchgeführt habe, reagiert das System öfter nicht. Was kann ich dagegen unternehmen?
The processing of a large number of music files requires Teufel Streaming system resources. This is normal and comparable to a computer that has multiple programs running at the same time. For most music libraries, this does not pose a problem. For exceptionally large libraries, however, such as those in the terabyte range, the system might be strained to a point where normal streaming is compromised.

Solution: Restart all Teufel Streaming devices and deactivate Chromecast built-in.
Der Stream auf meine Teufel Streaming Geräte über Chromecast beginnt erst nach langer Wartezeit oder startet gar nicht. Woran kann das liegen?
There are many possible reasons why your music stream doesn’t start or only begins after a long delay. The following are the most common causes:

1) Chromecast built-in functionality can vary between providers. It’s therefore important to abide by the instructions given by the provider for using this technology. For instance, some request that users first cast and then start an audio stream while others recommend the reverse order of actions. If you are unsure whether you are casting correctly, please ask your app’s service team for assistance.

2) It can take around 20 seconds or even longer in some cases for a stream to be processed. Contact the provider of the music or audio service you use to learn more.
How can I tell if my Teufel Streaming/Raumfeld devices are compatible with Chromecast built-in?
Chromecast is supported by Teufel Streaming / Raumfeld devices which have a Raumfeld logo on the front panel and no external Wi-Fi antenna on the rear panel. Chromecast is also supported by the Raumfeld Soundbar / Sounddeck and the Teufel Sounddeck Streaming / Teufel Soundbar Streaming.
Wie kann ich das Chromecast built-in für aktivieren?
Chromecast built-in can be activated on your Teufel Streaming device once it has updated its firmware to version 1.60 and actualised the Teufel Raumfeld App (iOS/Android). The app will then automatically display the presence of Chromecast-enabled devices present in the network.

Manual activation can also be completed at any time in the Teufel Raumfeld App’s menu under “Music services”.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
Which cables do I need to connect a Teufel speaker set to the AV Receiver?
A home cinema system needs speaker cables to connect the satellite speakers to the receivers, and an NF mono RCA cable to connect the active subwoofer to the sub out socket of the AV Receiver.
Access to my Expand (previously called Base) via Finder is slow or not possible at all
We have received feedback from a few users that accessing the network share "Raumfeld Expand" via Finder may take long or is not possible at all.

In order to solve the problem, perform the following steps on your Mac:

    * Open System Menu > Software Update... and make sure you've installed the latest software version. Otherwise perform a software update.
    * Disable spotlight for the Raumfeld Expand by adding the Expand's "MUSIC" folder to the list of locations under System Settings > Spotlight > Privacy.

Should the speed of access not be improved by these settings, please get in touch with our service team.
Kann ich meinen Expand (alte Bezeichnung Base) auch mit einer größeren Festplatte geliefert bekommen?
At present the Raumfeld Expand is only being sold with an hard disk size of 160 GB. However, the storage space of your Raumfeld Expand can be extended by connecting hard disks onto the two USB 2.0 inputs. Another possibility to increase the storage capacity of the complete system is to integrate an NAS (Network Attached Storage) into your network (Also look up Music Resources in the online manual).
My Expand (previously called Base) does not start (left LED lights up, middle LED flashes every 5 seconds).
If the Raumfeld Expand doesn't start properly after setup (left LED permanently lid, centre LED flashing every 5 seconds), it doesn't receive an IP address from your network router.

We suggest to probe the following solutions step by step. Should the problem persist afterwards, please get in touch with our service team.
  • First make sure that the router is connected to the proper port (right network port, labelled "ROUTER"). To connect a computer, always use the network port on the left (labelled with a network symbol).
    If you operate the Expand without a connection to your network router make sure that the ROUTER port is free.
  • Reboot your network router.
  • If the problem persists, check the settings of your network router:
    • DHCP must be activated
    • The DHCP server should automatically assign IP addresses to computers in the network.
    • If you prefer not to enable automatic IP addresses, make sure a static IP address is assigned to each device. Please note that the same IP address must not be assigned to multiple devices.
Der Raumfeld Expand (alte Bezeichnung Base) reagiert nach dem Update nicht mehr. Was kann ich tun?
Should the Expand not react after installing an update please remove the power plug for at least 3 minutes. Afterwards, the Expand should boot normally.
Should removing the power plug not be sufficient to restore system functionality, please perform the following steps which will recover the Expand.  Hereby, all settings and data stored on the internal hard disk of the Expand will be preserved.

Instructions for Expand Recovery
Please first download the file "base.img" and copy it to a USB stick:

Then perform the following steps:
  1. First remove the Expand's power plug for at least 30 seconds.
  2. Then, connect the USB stick to the upper USB port of the Expand.
  3. Press and hold the setup button on the back of the device while you attach the Expand's power plug in order to start it.
    Please press and hold the setup button for 10 more seconds.
  4. After max. 30 seconds the outer and inner LEDs will start to blink alternatingly. This indicates that the recovery has been started. Please note that the recovery may take up to 5 minutes. After that, the Expand will reboot automatically.
Do I need a Raumfeld Expand (previously named Base)?
A Raumfeld Expand is recommended in a multi room system. If you would only like to play music in a single room you only need a playback device and a controller (Raumfeld Controller or Teufel Raumfeld app for your smartphone).

Role of the Raumfeld Expand
  • By creating a dedicated Wi-Fi network it provides the bandwidth for a lossless transmission
  • By connecting to your home network the Expand is able to access your music stored on a computer or NAS (network attached storage). With the Raumfeld Controller you then have access to your complete digital music library.
  • If you own a Raumfeld Expand the size of your music library may exceed 200,000 tracks. Instead, without the Raumfeld Expand, the maximum capacity of your music database is about 50,000 tracks.

Should you wish to extend your system with a Raumfeld Expand, get in touch with our customer service team.
My devices' wireless signal is permanently low or breaks down frequently
To gain an overview over the signal strength of each Raumfeld devices in your network, open Settings > Network > Network Analysis.

A Loss of WLAN Signal

The constant loss of a device's Wlan signal even at high signal strength is due to interferences with other wireless networks. By changing the Wlan channel, you eliminate this interference and can fix this issue. Should your system contain a Raumfeld Base simply try out different channels as described in the online manual (Modifying of the Channel Setting (Raumfeld Base)) and see if the signal strength becomes steady. Access points from other manufacturers usually offer an according configuration option in their administration interface. 

Alternatively you may contact our service team, which is happy to assist you with the detection of the best channel available.

B Constant Low Signal Strength

If the signal strength of individual wireless devices is constantly beneath 50%, steps should be taken to upgrade the Wlan reception of the device and therewith the music playback reliability. In most cases it is sufficient to reduce the distance or the number of obstacles between your Raumfeld Base and your playback device. Simply check out if the reception increases when positioning the devices at different places.

In general, the less walls and ceilings between the devices, the better the reception is. Thick walls made from concrete or clay brick will especially abate the signal. Often a relocation of a few centimeters is enough to bypass any problems.

Mind the following advice that accounts for both, systems with Raumfeld Base or systems that are run with an access point from another manufacturer:

  • Position the Raumfeld Base or the third party access point you utilise rather high up, on a cupboard for example. Make sure there's some space towards the wall. Do not position the device on the floor or in a corner.
  • If you make use of a wireless phone there may be interferences with the wlan signal. Therefore, do not position the Base or the third party access point you utilise right next to the phone's base station.
  • Set up the devices in a way that ensures there are a minimum amount of obstacles inbetween your access point and the playback device. Avoid setting up the Raumfeld devices in alcoves or behind prominent corners.
  • Make sure there are no large-scale metal bodies between the access point and playback devices (e.g. radiators or fridges)
  • Large plants may also block the signal due to their moisture content and should not be between the access point and playback devices.
 If the reception does not increase after a repositioning we suggest using a standard Wlan repeater or to connect single components of your Raumfeld system with your existing wireless access point (see Connecting of your Raumfeld devices with your personal access point in the online manual). Please contact our service team to find the perfect solution for you.
I’m only able to access the Raumfeld Zones under “available devices“ in my Spotify App. How can I control the individual rooms?
Deactivate the Multiroom Mode for Spotify in the Raumfeld App by switching to the "off“ setting. You will then be able to individually control each device in the Spotify App.
The individual titles of my compilations are each displayed as their own album
Compilations or soundtracks are normally composed of various artists. In order to display them as a complete album, the tracks of a compilation must be grouped.

There are many different methods of accomplishing this, assuming that the same album name, or Album Tag, is assigned to all tracks. 
  • Assign the name of the compilation's producer to the tag Album Artist. Use "Various Artists" if the producer's name is unknown.
  • If you use iTunes, you may select for every song that they are Part of a Compilation under Get Info > Info.
  • As long as the album is stored locally on the Raumfeld Base, a network drive or USB storage, it is sufficient to simply save the music files in the same folder. Make sure, however, that only music files pertaining to the compilation are stored within this folder.
In order to edit your music collection's tags, we recommend the following programs:

Media Players
  • iTunes (Windows, Mac OS; only supports MP3, AAC, M4A, Apple Lossless)
  • Windows Media Player (Windows; only supports MP3, WMA)
  • Winamp (Windows; supports the same formats as Raumfeld except for WMA, WAV)
Special Tag-Editors
  • MP3-Tag (Windows; supports the same formats as Raumfeld except for WAV)
  • MusicBrainz Picard (Windows, Mac OS, Linux; supports the same formats as Raumfeld except for WAV)
Teufel Streaming (Raumfeld) basics
Would you like to get a comprehensive overview about the possibilities of Teufel Streaming systems? Our Teufel Streaming manual informs you about the basics, operation and integration of music resources. Find out more in the Teufel Streaming handbook: https://manual.teufel.de
I have no more access to the internet radio directory TuneIn in my Teufel Raumfeld app. What could be the reason?
For the further use of the radio service TuneIn, a software update may be required. The update is free of charge and only takes a few minutes. The software can easily be checked and updated:
  1. Start up all devices and opening the Teufel Raumfeld App.
  2. The main menu can now be called up on the app screen by briefly swiping to the right.
  3. First select "Settings" in the main menu, then menu item "System maintenance" and finally "Updates". By simply tapping on the "Check for updates" button, the device will automatically start to search for and download the latest version.
  4. After the download is complete, the update can be re-started by pressing the button again. This takes a maximum of about 3-5 minutes. Afterwards, TuneIn can be used again as usual.
I copied new music to a network share. Why isn't it displayed under My Music?
When you copy new music to a network share you have to manually initiate a rescan in order to see the music on your Controller or in the Raumfeld App, respectively.

In order to do so, go to My Music > Recently Added and tap the button "Update music index" on bottom of the list. Alternatively, visit Settings > Music Resources and activate a scan for new music on the music resource you've copied the music to.

Under Settings > Music Resources there is also an option to make your Raumfeld System check for new music every day. A manual scan is then not necessarily required.
Can different music (Multicast) be played in different rooms?
Multicast (different music in different rooms) is possible with Spotify, but not simultaneously. Due to certain restrictions stipulated by the provider, simultaneous multicast is not possible at the present time.
I use a version 6.0 Android device and am trying to set up my Wi-Fi streaming system. The setup assistant, however, does not continue after the initial screen. How can I proceed?
Make sure that your smart device is signed in to your home WiFi – the same WiFi network you plan to use with your Wi-Fi streaming system. If you are already signed in to your WiFi network, deactivate your smart device’s access to mobile internet for the duration of the setup.
I use an Android device version 6.0 or higher. The music I stream directly from this device drops after a short time. What could be the reason for this?
One reason could be that your smart device is going into standby mode and dropping the connection.

Solution: Add the Teufel Raumfeld app to your standby exception list, also known as your device’s “whitelist.” To do this, go to “Settings” in your Android menu and then “Apps,” “Advanced,” “Battery optimization,” “All apps” and “Raumfeld.”
I can find settings for my subwoofer in the Teufel Raumfeld app. What are these for?
The menu items "subwoofer volume" and "subwoofer crossover frequency" are only stored in the app menu under "room settings" if a Teufel Streaming soundbar is operated over the same Wi-Fi connection. With a soundbar/subwoofer combination, the sound signal is "distributed" to the devices, i.e. the sounbar outputs the higher frequencies and the subwoofer, the lower ones. This signal distribution is defined under the menu item "subwoofer crossover frequency". Installation tips:
  • Leave the crossover frequency on the default setting if you are satisfied with the sound or if the Teufel Streaming subwoofer is located close to the soundbar (recommended).
  • If the subwoofer is placed at the side or at the back of the room, it is possible that the overall sound may no longer be harmonious. In this case, try changing the crossover frequency in the app until you are satisfied with the sound.
  • If, for example, the sound image of the soundbar is too thin, reduce the crossover frequency. If the bass sounds too flat, increase the crossover frequency.
  • You can also adjust the subwoofer volume separately.
Can I use my home cinema with the Teufel Streaming system?
In order to use your home cinema system with your Teufel Streaming system you require a Connector:
  • Connect the analogue or digital output of the Connector to an appropriate input of your home cinema amplifier
  • Connect an analogue output of your amplifier to the analogue input of the Connector
This will allow you:
  • to listen to music from your Teufel Streaming system via your home cinema system
  • to stream the audio signal of TV series or movies into other rooms of your house
Please note that there will be a short delay between video and audio signal when you stream it into other rooms. If you choose to play the audio signal via your home cinema system only, audio playback is of course in perfect sync with the video signal.

Do I need to be experienced with technology (Wi-Fi, SSID, WEP, computers, Internet, programming)?
Knowledge about wireless networks or computer technology is not necessary for setting up or using the Teufel Streaming systems. New devices are added to the system simply at the touch of a button.
The Teufel Raumfeld app setup wizard does not find a device after pressing the setup key on the back of the device. The display shows "Searching for device..." or "No device found". What can I do?
There are many reasons why a Teufel Streaming device may not be found during setup, i.e. when the app displays the notifications "Searching for device“ or "Not found”. The following will cover the most likely causes as well as possible solutions.

1) It’s possible that your home Wi-Fi is unable to recognise the device due to certain settings on your Wi-Fi router.

Solution: You can enable your Wi-Fi to recognise the device by directly connecting the Teufel Streaming device to your router via Ethernet cable and repeating the setup process.

2) Other active network devices may prevent your Wi-Fi router from recognising the device. Solution: Deactivate all devices (such as smart TVs, laptops, smartphones, tablets, AV receivers, media servers) that use your LAN or Wi-Fi network for the duration of the Teufel Streaming setup process. Before beginning a new setup process, be sure to restart your Wi-Fi router and complete the setup using a single smartphone.

3) The use of switches, repeaters and additional access points within your home Wi-Fi network can hinder device recognition. Solution: Either restart all additional network devices or turn off these devices for the duration of the setup process.

4) If you use a cordless phone over a landline (DECT) and have this phone in the vicinity of your router or Teufel Streaming device, it may be disrupting your Wi-Fi signal. This is because both DECT and Wi-Fi use the same 2.4 GHz signal.

Solution: Relocate your DECT base station or switch off your DECT telephone for the duration of the setup process.
The Teufel Raumfeld app indicates an error after selecting the Wi-Fi and entering the network key (Wi-Fi password). What could be the reason for this?
If you're using a smart device with the Android operating system version 5.X (Lollipop), the problem could caused by two possible smart device settings:

1) The setting "Smart network change" switches the smart device to the mobile network whenever the WiFi signal becomes too weak. Since Teufel Streaming requires a continuous Wi-Fi connection, this setting cannot be used.

2) The "Auto IP Support" function determines when the home Wi-Fi network does not support DHCP (the automatic assignation of a network address). Although a very useful feature, Auto IP Support cannot be used with the Teufel Streaming system. This is because Teufel Streaming devices need to be assigned an IP from the router in order to independently communicate with the home network and internet.

Solution: The Android functions "Smart network change" and "Auto IP Support" should be deactivated. Next, ensure that your router allows for DHCP and then repeat the setup process.
Die Teufel Raumfeld App zeigt einen "Hoppla"-Hinweis unmittelbar nach der Raumnamen-Vergabe. Im Display steht "Gerät wird konfiguriert". Woran kann dies liegen?
Other devices in your WiFi network may be preventing the Setup Assistant from completing the setup process.

Solution: Deactivate all devices (such as smart TVs, laptops, smartphones, tablets, AV receivers, media servers) that use your LAN or WiFi network for the duration of the setup process. Before beginning a new setup process, be sure to restart your WiFi router and complete the setup using a single smartphone.

Please note that the processes carried out during the notification "Configuring device..." may take a few minutes to complete. We therefore ask for patience in order to ensure that the setup is indeed experiencing difficulty completing and that your smartphone does not go into standby mode.
Während der Einrichtung muss das WLAN-Passwort eingeben werden, damit Ihre Geräte im Heimnetzwerk angemeldet werden können. Was kann ich machen?
Check that the password you entered is still current. Make sure that you are not using the password for your SIM card, Google account, music service or other account. Teufel Streaming requires the password for your home WiFi. This is sometimes also called the "network key".

Tip I: You'll often find your WiFi password / network key on the back of your WiFi router. As long as this password has not been changed, it should still be valid.

Tip II: The auto correct function in your smart device may be changing the characters you enter. We therefore recommend switching off this auto correct function.
During setup, the Wi-Fi network via which the system is to be integrated in the future must be selected in the app. However, my home network is not listed in the selection list. What could be the reason?
The following are a few reasons why your Wi-Fi network may not appear in the list presented in the app:

1) If the signal strength of your Wi-Fi network is only 30% or less where you are holding your phone, it will not appear. Since the system requires a signal strength greater than 30% in order to function without drops in playback, only networks that offer this minimum signal strength will be displayed.

Solution: Increase the signal strength of your Wi-Fi signal and/or find a better place for your device.

2) It’s technically possible to hide a Wi-Fi network. This option is usually offered in a Wi-Fi router’s settings. If you’ve selected this setting option, your home network will not be displayed within the app.

Solution: Make sure that the Wi-Fi is set to "visible“.
Während der Einrichtung zeigt die App die Meldung "Router inkompatibel" an. Woran kann das liegen?
There can be many reasons for the notification "Wi-Fi router is incompatible”. The most common reasons for this notification have to do with router configurations affecting your home WiFi which can be changed. The following are the most common WiFi settings that may be the cause:

1) The function DHCP (the automatic assignment of a network address) is not switched on. This prevents the Raumefld device from registering with the home WiFi network.

Solution: Activate the DHCP function in your home WiFi router’s settings. Tip: Some manufacturers list DHCP as a feature with names like “Reject unknown devices”. Contact the manufacturer of your router if you are unsure what this feature is called.

2) A so-called Mac filter is switched on in your router. This filter prevents the registration of unknown devices which includes all devices not already using the WiFi network.

Solution: Deactivate the Mac filter for the duration of the setup process or add your device to the router’s list of known devices. Note: Some manufacturers refer to the Mac filter with names like "Only allow known devices.“ Contact the manufacturer of your router if you are unsure what this feature is called.

3) The router is blocking direct communication (the exchange of data) between two or more devices connected to the same WiFi network. Known as “client isolation,” this setting is often preconfigured, especially with guest network access.

It requires direct communication in order to receive information (such as when you press "play“) from your smartphone. The client isolation setting is often overlooked as it does not prevent a device from accessing the internet.

Solution: Do not use a guest WiFi access for your device; deactivate the client isolation feature.

Note: Some manufacturers refer to client isolation under different names. It may also be a preconfigured part of a security level you have chosen for your WiFi network. Contact the manufacturer of your router for more information.
How can I install software updates?
All Raumfeld devices regularly connect to the Raumfeld update service to look for updated software versions. If updates are available you can easily install them at the push of a button.

Hence your components keep up to date and you can benefit from advancements in the latest software releases.

Since Raumfeld software version 1.3 it is also possible to install updates via a USB stick. This enables you to apply updates without an internet connection.

Of course we also provide continuous updates of the Raumfeld App for your smartphone. These updates are distributed via your smartphone's app store.
My USB storage is not recognised
Connected to the Raumfeld Base
When USB storage is attached to the Base your Raumfeld system will automatically begin to scan for new music. You can follow the scan progress under Settings > Music Resources. The following are possible causes as to why your USB storage may not be automatically found:

A) The file system of the disk may not be compatible. We support the following formats:

  • FAT16 / FAT32
  • NTFS
  • HFS / HFS+
  • EXT2 / EXT3 / EXT4

B) We seldomly have had reports of issues with USB 1.0 devices. We therefore recommend using devices that support USB 2.0.

Connected to a Raumfeld Speaker or Connector (System without Raumfeld Base)
USB storage that has been connected to a Raumfeld Speaker or Connector can only be used for playback in the Raumfeld system if the device is configured as the Raumfeld Host (see Network in the online manual).

Please also note that for first-generation Speakers and Connectors, apart from USB sticks only USB 2.0 storage with its own power supply or USB sticks are supported. These constraints do not apply to second-generation devices, e.g. Connector 2.
Can I control the Raumfeld System from an iPod Touch or iPhone?
The Raumfeld Controller App turns your iPhone, iPod touch or iPad into a full controller for your Raumfeld multi room audio system. It is available free in the app store.
What is the difference between active and passive speakers?
An active speaker contains the amplifiers for the pair of speakers. You can easily recognise it as it also holds the power connector and the Wi-Fi antenna. The passive speaker is connected to the active speaker via a speaker cable.
Is it possible to combine several pairs of speakers in larger rooms?
If you want to provide a particularly large room with music, you can easily set up several Teufel Streaming speakers in one room. The Room Configuration settings allow you to assign multiple devices to a single room so that you can easily control music selection and volume.
Which Spotify subscription plan do I need in order to stream music (on a single device or in a multiroom setup) from Spotify to my Raumfeld device?
In order to listen to Spotify with your Raumfeld speakers, you need to subscribe to Spotify Premium. Due to certain restricitons stipulated by the provider, the free account is not sufficient to stream with the system. You can learn more about Spotify Premium here
I activated my iPhone/iPad as a resource in Raumfeld. However, it frequently is displayed as being “offline” even though it’s logged in to the Wi-Fi. What causes this to happen?
This can occur when multiple mobile devices are used with Raumfeld at the same time. The iPhone/iPad goes offline after 10 minutes if not in use. This conserves the battery on the iPhone/iPad.

Solution: If the resources are offline, simply open the Teufel Reumfeld app on the device from which you would like to stream digital content.
Welches Netzwerk-Protokoll (SMB) muss ich einstellen, wenn Teufel Streaming auf Musik, gespeichert auf Netzlaufwerken oder in Ordnerfreigaben zugreifen soll?
With network protocol SMB1 Teufel Streaming recognises music files on network drives or folder sharing the best. Set the SMB1 protocol in the properties of your computer or /NAS to listen to music via Teufel Streaming.
Do I need other devices to help make the Raumfeld One work?
No, there are no additional devices and/or appliances needed for the Raumfeld One. All you need is a remote, which can be your Raumfeld Controller or simply use the free Raumfeld App via your Smartphone with iOS or Android (iPhone/iPod Touch/iPad or Android). Needless to say, a wireless access point (Router) over internet (ethernet) is required.
Why does the One S come with an allen screw?
The included allen screw makes it possible to attach the One S to a wall mount. You’ll find the corresponding bolt hole beneath the removable magnetic base plate (only with the 2nd generation).
Which components do I need to expand my stereo system to a surround system?
Next to additional speakers (centre, rear, R/L, active subwoofer), you will need the following devices:

• Television: A conventional TV set will suffice. Naturally, devices with a 16:9 format are recommended for playing back DVDs.

• AV surround Receiver: This multichannel amplifier with integrated radio and decoder for Dolby Digital/DTS replaces the stereo amplifier. As minimum equipment, the device should have power amplifiers with approx. 5 x 40 watt output.

• DVD player: This devices supplies the video and audio signals, plays back a number of digital formats, also plays music CDs and MP3 files and is connected to the receiver.
I connected the Sounddeck / Soundbar to my television via HDMI cable. The device is recognized yet no sound - or only partial sound - is produced. What can I do?
Please check to see whether your television supports the HDMI-ARC standard and whether the product is connected to your TV from this output. Alternately, you can use a digital-optical cable to connect the two devices.

It's also a good idea to check the sound setting on your television (or set top box). This should be set to PCM or stereo. If the audio signal travels from the set top box to the product via the television, please make sure that both devices have been correctly configured, or connect the audio signal from the source device to the product directly.
I have a Raumfeld Soundbar/Sounddeck connected to my TV via HDMI cable. Whenever I start apps like Netflix or Amazon Prime via the TV menu, I don’t hear any sound. What can I change in the system settings so that I hear playback with these services?
Switch the TV sound setting to PCM (stereo) in your television's menu. If your television doesn’t offer PCM (stereo/downmix) as an option, you can connect the Soundbar via an analog TV output (e.g. Headphone output).
How can I configure the type of television connection on my Soundbar?
In order to change the type of connection, open the Raumfeld App and go to “Room configuration“ (under Settings/room configuration/room name/device) and change the type of connection to “TV input” in the drop down menu.
What’s the purpose of the 1 to 4 buttons on the remote?
The buttons serve two purposes. If the Soundbar is connected via HDMI-ARC, AUX or OPT, you’ll be able to use these buttons to select from the various Wellenfeld modes. When playing back audio via Raumfeld’s music streaming function, the buttons 1 – 4 serve as preset buttons for saving your favorite streams.
How can I select one of the four Wellenfeld modes and what do they do?
For playback via TV, AUX or OPT connection, the buttons marked 1 – 4 on the included remote can be used to select the desired Wellenfeld mode. The setting can also be accessed via the Raumfeld App. (Menu path: Settings/Room configuration/”Room name”/Device name/Wellenfeld mode)

The following settings can be selected:
  1. Stereo Mode: The sound is similar to that produced by a classic stereo system. Select this mode to enjoy music with a broad stereo soundstage. (Button 1)
  2. Arena Mode: This mode employs side-mounted drivers to create an especially broad sound panorama. (Button 2)
  3. Theater Mode: The Theater Mode creates a broad soundstage together with heightened speech intelligibility.
  4. Voice Mode: This mode elevates the voice frequency range for enhanced speech intelligibility while using the side-mounted drivers to subtly broaden the soundstage. (Button 4)
I am unable to find any setting options for DTS or Dolby Digital on the Soundbar. How can I activate these audio codecs with my movies?
The Teufel Raumfeld Soundbar does not offer decoders for DTS or Dolby Digital. This is because the Soundbar uses Wellenfeld Technology, specially developed by Raumfeld for the creation of room-filling sound from a single loudspeaker enclosure. We decided not to include Dolby Digital or DTS because, while they are excellent sound technologies, they are only of limited use with single-enclosure systems such as the Raumfeld Soundbar. Intended for surround sound speaker systems, neither codec will be able to produce a truly convincing surround panorama from a soundbar.
There’s a night mode in the device settings. What is its purpose?
The night mode reduces bass levels while simultaneously enhancing the speech intelligibility of the system. This mode is perfect for those who don’t want to disturb their neighbors or for adjusting the system to account for individual room acoustics.
I have a Raumfeld Soundbar with subwoofer. I located the option for setting the subwoofer’s crossover frequency and volume within the app. What is this for?
Under the menu option "Subwoofer crossover frequency,” you can determine up to what frequency the subwoofer should play. We recommend leaving the crossover frequency at its factory setting if you plan to position the Raumfeld Soundbar in the immediate vicinity of the subwoofer. If the subwoofer is placed further away, such as towards the back of the room, a less harmonious soundstage may result. In this case, you can change the subwoofer’s crossover frequency in the app until you are happy with the sound. If, for instance, the Soundbar’s soundstage seems too thin, you can lower the crossover frequency. If the bass seems too flat, simply raise the crossover frequency.

It’s also possible to perfect the system’s soundstage by altering the subwoofer’s volume levels.
The remote control that came with the system doesn’t work. What can I do?
Before using the remote, you need to remove the plastic tab from the end. The plastic tab prevents the batteries from being engaged while the device is transported. Next, press the 1 and 4 buttons at the same time for a total of 10 seconds while standing near the Soundbar. This procedure introduces the two devices to each other and only needs to be carried out once. Once paired, the two devices will henceforth automatically recognize each other.
How do I connect my Soundbar to my television?
Televisions can be connected with an HDMI-ARC cable (recommended), optical digital cable (TOS-LINK) or RCA cable. The Soundbar was pre-configured for the HDMI-ARC connection. Therefore, if your TV offers an HDMI-ARC connection, it’s best to connect both devices with a compatible HDMI cable. This is all the two devices will need in order to communicate with each other. If you plan to connect the Soundbar with an optical digital or RCA cable, you’ll need to adjust the settings.

In order to change the type of connection, open the Raumfeld App and open the “Room configuration“ option (under Settings/room configuration/room name/device) and change the type of connection to “TV input” in the drop down menu.
The product has integrated Wellenfeld Technology. What is this and what does it do?
The Wellenfeld Technology developed by our acousticians here in Berlin uses four different sound modes (Stereo, Arena, Theater and Voice) in order to perfectly adapt the sound to the type of audio being played back.
Wie wechsle ich die Batterie der Teufel Streaming Soundbar/Raumfeld Soundbar? Fernbedienung RFRC1?
Drehen Sie bitte am unteren Ende der Fernbedienung beide Schrauben komplett heraus, gehen Sie dann z.B. mit einem dünnen Schraubenzieher in eines der beiden Schraublöcher und ziehen Sie das Fach vorsichtig heraus. Nun haben Sie freien Zugriff auf die Lithium-Batterie (CR 2032).
What’s the best place to put the Raumfeld Subwoofer?
The optimal placement of the Subwoofer is in front of the seating area, to the left or right of the Soundbar. If this is not possible, the Subwoofer can be placed elsewhere. Due to its flat design, the Raumfeld Subwoofer can even be slid under the sofa or under a sideboard. Before deciding on a permanent home for your Subwoofer, it’s a good idea to try out a few different locations for the best bass sound. If you’re not happy with the bass playback produced in a certain area, try an alternative spot or adjust the phase (located at the back of the device) to the “180” position.
How can I regulate the levels on the subwoofer?
The subwoofer levels can be regulated in the Raumfeld App (Menu path: Setting/Room configuration/Room name/Device) according to your preferences.
On the back of the Raumfeld Subwoofer are various switches and controls. What can I adjust with these?
Answer: The Raumfeld Subwoofer offers the following setting options on the back of the subwoofer:
  • The “Phase“ slide switch: This is where you can optimize the subwoofer’s signal output. Try adjusting the phase setting if the conditions of the room where your Subwoofer is situated cause it to drone or sound strange.
  • „Sub Level“ dial: (Can only be used in the device’s wired mode) This allows you to adjust the sensitivity (volume) of the incoming signal. If the device is being used in its wireless mode, you can adjust these settings via the Raumfeld App.
  • „High pass“ dial: This allows you to filter out all frequencies beneath a certain cutoff frequency. For instance, if the dial is set to 50 Hz, the Subwoofer will not play back any frequencies lower than 50 Hz. If you want to hear bass playback without any filtering, we recommend a setting of 20 Hz.
Will an active subwoofer only run in 5.1 mode or also in stereo mode?
Thanks to the speaker set-up/bass management integrated in the home cinema receivers/amplifiers, the subwoofer functions in stereo, Dolby Surround and digital mode.

The corresponding setting in the speaker set-up must be adjusted individually for each source for many receivers, however, e.g. for CD playback only front without woofer, and front speakers plus woofer for Dolby Surround video playback.
Why doesn't my active subwoofer switch on automatically?
Some AV Receivers/amplifiers issue the bass signals via the subwoofer pre-amplifier output so quietly that the subwoofer does not start automatically.

To make sure the subwoofer switches on and off correctly in automatic mode, (to be selected on the corresponding switch of the subwoofer, such as "Auto / On / Off"), we recommend turning the level control on the subwoofer to 1/3 or perhaps to 1/2 and increasing the output level for the sub in the receiver's speaker set-up – sometimes up to the maximum (+10 dB or +12 dB). The subwoofer should then work perfectly.

The maximum position of the output level in the speaker set-up of the AV Receiver is obligatory for some of our models (e.g. the Concept S subwoofer).
How do I connect my fully active Teufel system to an AV Receiver?
Although designed to be fully active, the Teufel set is also partially active in conjunction with an AV Receiver.

You can connect it like a standard speaker system: the five satellites via speaker cable to the corresponding speaker outputs front R/L, rear R/L and centre of the AV Receiver/amplifier and the subwoofer from the front R input via a mono-RCA cable to the Sub Out output on the A/V Receiver/amplifier.

Please note:
The auto on/standby switch only responds when the front R input is being used! The subwoofer also receives the full subwoofer signal via this channel.

If the AV Receiver/amplifier has preamplifier outputs for all channels (front R/L, rear R/L, centre and subwoofer), the Teufel set can also be connected via three RCA cable pairs to the subwoofer and the satellites via speaker cables to the subwoofer. However, we recommend using the first version.
What is the use of the on/off automatic switch ("Auto On/Off") of the active subwoofer?
The On/Off switch is a power-saving standby switch. The switch must be set to "On" or "1" to activate the standby. The subwoofer is activated as soon as it receives a strong bass signal. After approx. ten to twenty minutes of no signal, or only after receiving a very weak signal, it automatically switches to the standby function.

Even though the LED is still illuminated, the subwoofer is in standby mode. This function can be easily checked by slowly increasing the volume at the receiver/amplifier. You will hear a quiet popping noise when the subwoofer activates itself as of a certain level.
What happens to the power amplifiers of the subwoofer if I don't connect the satellites?
As soon as the satellites are connected to the subwoofer and not to the AV Receiver/amplifier, the performance of the 6 or 8-channel power amplifier is distributed to the subwoofer and to the satellites.

If the satellites are not connected directly to the subwoofer but to the AV Receiver/amplifier via speaker cable instead, the subwoofer performance will increase somewhat; the power amplifiers for the satellites have no function. This enables the subwoofer and satellites to play even more dynamically than if the subwoofer still had to provide the satellites with performance.

The technical background: The subwoofer has a large transformer with a specific wattage. This performance is either distributed to the five satellites and the subwoofer, or you receive a higher performance only for the subwoofer.
How can I connect an additional active subwoofer?
If your receiver has only one subwoofer output ("Sub Out"), you only need a monocinch cable, which is then connected from the receiver to the "Sub In" of the subwoofer. With two subwoofer outputs, you can order a so-called Y-adapter from the Teufel accessories page, which has a cinch plug on one side and two cinch (RCA) sockets on the other. Connect the plug to the subwoofer "Pre Out" on the AV receiver/amplifier and connect the mono cinch cable to the two subwoofers.

If the cabling method is easier for you, then you can alternatively connect one subwoofer to the other. You will need two mono cinch cables - one to connect the subwoofer "Pre Out" on the AV receiver/amplifier to the left line-in input of the first subwoofer, and the other to connect the left line-out output of the first subwoofer to the left line-in input of the second subwoofer.
What are the volume switches for?
The sound of the speaker always depends on the room where it is located.

The volume of the active subwoofer can be controlled so that you can adapt the relationship between the active bass and treble / mid tones to suit the room.

Use your own senses to judge which settings sound best in your room. This switch is especially useful in stereo mode. On the other hand, multichannel amplifiers often have technologies that adjust the subwoofer volume - so when using a multichannel amplifier the controller should first be set at 0dB.
No sound with high sample rates (Connector 2)
The Raumfeld Connector allows playback of music files with very high sample rates (up to 192 kBit). By connecting it to your stereo receiver you are able to enjoy high resoultion music files on your stereo set.

Unfortunately not all stereo receivers can process high sample rates on the optical input. If the Connector sends a signal with a higher sample rate than your stereo receiver is able to process it will not play the signal. Hence there is no sound.

In order to solve this problem the Connector offers the configuration option "Maximum sample rate on optical output". You will find it under Settings > Room Configuration > (Room name of Connector) > Connector.

This option allows you to set the maximum sample rate your stereo receiver is able to process. The Connector will then down-sample material with a higher sample rate to the denoted maximum sample rate.
Ich nutze den optischen Ausgang am Connector. Die Lautstärke ist aber nun nicht mehr über die App regelbar. Was kann ich machen?
Bei einer Signalausgabe über den optischen Ausgang am Connector kann die Lautstärke nicht via App geregelt werden.
Nutzen Sie stattdessen den analogen Ausgang des Gerätes oder regeln Sie die Lautstärke am angeschlossenen Verstärker.
I have a Connector connected to my system via a digital optical cable and sometimes experience drops in the music stream. What can I do to ensure even playback?
You can adjust the maximum sampling rate in the Connector’s configuration menu within the Raumfeld App. Try reducing this rate until your streams of music play without drops. If this does not help, activate the “fixed clock” option by checking the box. You’ll find the Connector’s configuration menu in the Raumfeld App under Settings>Room Configuration>Your Rooms(Select Connector) > Room Details(Select Connector again).
