"Due to the use of a Cirrus Logic D/A converter chip, the quality of the analog output is very satisfactory. The bass that is delivered to the amplifier is rich and the treble thoroughly nuanced, the stereo image is detailed and is a lot of fun to listen to.”
"Raumfeld systems offer a well-executed introduction to the world of multi-room streaming. [T]he Berliners offer a good system that can be effortlessly extended and which can continue to be enjoyed in the future. Devices with similar qualities [...] can only be found in a higher price class. Ever the Raumfeld Connector²‘s sound is a winner."
The well-constructed unit enables existing hi-fi owners to access home networked music libraries found on computers, NAS drives and mobile devices."
" [...] the app, which is surprisingly intuitive to use and comes preloaded with access to Spotify Connect – so long as you have a Premium subscription – Napster, TuneIn and Last.fm streaming services. The app is nicely configured and easy to master with volume and EQ control for each room around the home should you decide to go down the multi-room path."
"Detail across the frequency range is impressively integral, and the soundstage has a good sense of left-to-right and front-to-back depth [...]"
"[...] the real pleasure of the Connector 2 is in its integration with Tidal’s streaming service, giving me access to its extensive catalogue of tracks [...]"
"The Connector 2 offers a high level of networking possibilities and access to music streaming services. Its app is one of the most integrated I have seen, and offers tremendous flexibility at the price"

"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."
"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."
You can read the full test review here:
Setup and operation of the Raumfeld Connector can be executed via an optional remote control (Raumfeld Controller) or free app for mobile operating systems Android and iOS.
[...] As soon [...] as the setup assistant is finished, it’s easy to play music from USB storage devices and DLNA servers, accessible computers, and music services like TuneIn, Napster, Simfy, or Last.fm. The current firmware can even handle extremely large music libraries (150,000 files) on network drives and USB devices. As one would expect from a high-end network player, high resolution audio files and gapless playback is supported.
The Raumfeld Connector is the perfect partner for systems lacking their own network functionality. The setup is quickly mastered, operating the device is simple, and the sound impressive."
Translated from the original German.
"Those who are not just looking at comfort when it comes to multiroom, but maximum sound quality as well should take a closer look at Raumfeld. The system plays nearly all file formats, including many lossless and high resolution varieties, and therefore guarantees maximum music enjoyment with minimum cabling effort.”
“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.”
“It’s fast, easy to operate, sounds good and is inexpensive to boot. With the new Connector 2, Raumfeld gains ground on its main competitors.”
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."

"All this is contained within an attractive synthetic enclosure the size of a paperback. The device has two analog outputs as well as an optical digital output and a USB terminal for USB storage devices. With the current version of the Connector, 192 kHz and 24 bit are not a problem.”
"If you get tired of your own music, you can always make use of a pre-installed and thereby quickly accessible music service. [...] Thanks to a serious Cirrus Logic converter, the Connector produces an acoustic result that is simply outstanding [...]. A device in this or higher price class should try to beat it. One this is for sure: The Raumfeld system is and remains about the most stable and flexible solution for network streaming.”
"Whoever’s considering streaming but afraid to commit has run out of excuses. The Raumfeld Connector2 is easy to set up and has a sound so rewarding that anyone will be instantly and over the long run happy with it.”
Translated from the original German.
“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.”
“While many still shy away from networks, IPs, or UPnP servers, there’s no talk of that here. It doesn’t matter what network structure you have at home or where your music is stored. This little box is like an additional player for your system and can be attached via cinch cable or digital Toslink. The network connection is made via LAN or Wi-Fi. [...] Set up is child’s play. All connectors, Raumfeld streaming speakers, and UPnP devices in the network can be configured via the app and then made available to existing music archives.”
“Thanks to the very best Cirrus Logic converter, the sound streamed by the connector is truly amazing. Every type of music is played clearly with fine resolution and solid, highly accurate dimensionality. Another device in this or an even higher price class has yet to reproduce this quality. One thing’s for sure: The Raumfeld system was and remains the most stable and flexible solution for network streaming out there.”
“Whoever’s considering streaming, but is afraid to commit no longer has an excuse. The Raumfeld Connector 2 is so simple to set up and sounds so good that anyone can expect to derive immediate and long-lasting enjoyment from it.”

The Connector handles all lossless formats - bar DSD - at sample rates up to 24-bit/192kHz. Wired and wireless connectivity is supported and there's an analogue loop-through, which allows it to share an input with an existing source component, while the optical digital output allows you to use it with an external DAC.
The Connector is supplied with a dedicated app (iOS and Android), which is a slick and effective piece of software. Like others here, it renders the library on the controlling device, which takes longer to compile but is stable once complete. As well as your music library, there is Spotify Connect support and Tidal integration. There's no Bluetooth or AirPlay, but you do get Chromecast support built-in.
Having completed the simple setup and let the album library compile, the Raumfeld demonstrates more sonic character than some of the other streamers here and whether or not you like the effects of this will play a big part in how you get on with it. Adagio for Tron is presented with a small but appreciable life to the upper mid and treble. This helps the sense of separation and perception of individual instruments, so as the piece builds it can feel a little sharper and harder than some of the other players.
With the tonally darker recording of Dissolved Girl, the balance achieved is much more satisfying. There is a life and energy to the vocals that keeps them more defined and distinct from the electronics accompaniment that underpins them. Bass isn't the deepest here, but there is a speed and sense of agility to it that creates engagement with the listener. This also ensures the distinctive timing of Sinner in the Sea is delivered with assurance while highlighting the vocals and supporting instruments in a subtle but highly effective way.
That top-end lift is less effective with Mr Clean, though. Although a superb recording, the Raumfeld has the trumpet coming across as a little hard and sharp in comparison with some of the players here. The recording is presented with a good sense of space and three dimensionality, however. Moving on to hi-res material presents no playback issues, while the low-end agility is once again on hand to caputre the flow of Song of the Stars in a manner that consistently engages the listener. The Chromecast integartion is also effective, although rather more so with Android devices than it is with iOS ones where AirPlay is perhaps a more effective option.

Downloads & support
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.
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.
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.
- 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)
- Start up all devices and opening the Teufel Raumfeld App.
- The main menu can now be called up on the app screen by briefly swiping to the right.
- 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.
- 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.
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.
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.”
- 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.
- 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
- 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
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.
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.
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.
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.
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“.
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.
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.
After you create and name your groups, they will appear alongside individual Cast-enabled speakers in your music app.

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.
Solution: Restart all Teufel Streaming devices and deactivate Chromecast built-in.
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.
Manual activation can also be completed at any time in the Teufel Raumfeld App’s menu under “Music services”.
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.
Solution: If the resources are offline, simply open the Teufel Reumfeld app on the device from which you would like to stream digital content.
