Teufel One M Operation 
Acoustic genius
The Teufel One M offers a detailed sound image with rich dynamics and volume like no other streaming speaker of this size.
With nearly 40 years of experience, Teufel is the brand for the best-quality audio streaming. Not only do we have the most powerful speakers with a true stereo soundscape and 3-way configuration, but we also have the best acoustics even in compact dimensions for all-in-one, true-to-source audio reproduction. Here are the highlights of the Teufel One M.
Four tweeters
Two of the four tweeters are side-firing. Dynamore technology offers the best possible audio projection. So even if you are not sitting directly in front of the One M, you will still hear every little detail.
Powerful mid-range drivers
The 3-way mid-range drivers ensure that you will hear every small detail and optimum speech intelligibility.
7 amplifiers
Each active channel is driven by its own class-D amp. This allows for optimum adaptation to the drivers and guarantees a large power reserve.

Integrated subwoofer
The One M's new subwoofer allows for even more air flow than before so that the sound becomes even deeper. The long-throw construction offers a punchy bass, even at high volumes.
Passive Membrane
The two additional passive membranes eliminate unclean noise resonance. Never before has a single-speaker system played such clean, deep bass.
Everything goes
The Teufel Streaming speakers are fully compatible with other systems and services. Thanks to the extensive connection options, they can be transformed into a docking station.

Teufel One M review of Low Beats
Teufel One M review of Low Beats
"The Teufel One M delivered impressive dynamics..."
Low Beats 10.01.2018
"The Teufel One M delivered impressive dynamics, combined with a balanced and broadband reproduction, whose resolution, transparency and richness of detail was astounding."  

"With this compact system from Berlin, you can enjoy the essence of music with a powerful but balanced sound and amazingly deep, contoured basses. It can be said without exaggeration that there is nothing better for this price [...] The clarity and accuracy (wouldn't have thought it possible to use such words for an inexpensive Wi-Fi speaker) convinced me as a critical, high-end listener just as much as the danceability factor."

Teufel One M review of Lite Magazin
Teufel One M review of Lite Magazin
"...an impressive sound bankdrop"
Lite Magazin 28.01.2018
"[…] The One M can be used as a TV speaker, although music reproduction is its primary passion. It cannot be denied, however, that there has not been a good deal of thought put into the aesthetics and design."

"[…] Teufel has created a fairly lavish three-way system, […] since the Berliners ultimately want to elicit a real stereo stage from the one-speaker system. Of course, it is equipped with Dynamore technology."

"Even the quietest of sounds are convincing with a very good balance between clear treble and powerful bass, and with the stereo extension switched on, these strengths become even more pronounced. The virtual stage is at least as wide as promised and presents a clean gradation. […] Here the One M shows that, despite its compact dimensions, it can turn on the gas and delivers quite easily even at high levels. [...] it is also an excellent master of fine engineering [...]."

"Compact but all the more powerful in sound, the compact One M Wi-Fi speaker provides a solution to many a space problem without making any acoustic compromise. Thanks to acoustic stereo expansion, the single speaker system produces an impressive sound backdrop in a modern look that is comparable to compact Hi-Fi systems. It is also possible to integrate the speaker into the home network, which gives the One M an enormous variety of sources and the option of using it as part of a multi-room system. This is accompanied by a high level of operating comfort via smartphone or tablet, which rounds off the excellent price-performance ratio.”

Teufel One M review of Audio Test
"a real party starter"
Audio Test 02/2018
"When it comes to sound, he puts One M especially on the bass, which he puts in a bold light thanks to the integrated subwoofer. It produces a stereo image that is also clearly perceptible from a distance of two metres. […] The volume is really big. With the One M, 40 square metres of rooms can be sounded easily. We did not hear distortions or unsightly resonances even at maximum volume. The One M is a real party starter and brings along a good level of sensitivity even with quiet tones.”

"[...] The stereo, multi-room speaker convinces above all with its powerful bass foundation and the good fine definition of the other frequencies. The best way to control it is by app."

NB: Quotes refer to a "two-page test" of Teufel One M and Teufel One S in the Audio Test magazine. See full test report on Digital Tested.

"Teufel sets the bar high with their Wi-Fi speakers"
Audio Video Foto Bild 04/2018
"Teufel sets the bar high with their Wi-Fi speakers. The app could still use some fine-tuning but works well after a short time of getting used to it. The strongest members of the new speaker family are the two stereo pairs with their outstanding sound quality. You can get serious Hi-Fi sound and thus much more than one-speaker configurations. The One M model sits between the chairs: music lovers want a clearer sound, part-time listeners might have to reach deep into their pockets. But they'll be all the happier with the One S."

NB: Quote refers to a test of Teufel Stereo L, Teufel Stereo M, Teufel One M and Teufel One S. Teufel One M finished 3rd with a “good” score of 2.3.

"This makes listening to music fun!"
Android Magazin 03/2018
"Excellent. Teufel has not only succeeded with the One M as an optical eye-catcher, the speaker also convinces across the board with regard to sound quality. The finest details in the highs, mids and lower range are reproduced just as cleanly as powerful basses. This makes listening to music fun!"

NB: Quote refers to Teufel One M. It took first place with 5 out of 5 stars in a comparison test with a total of 4 test devices.

"a powerful sound system for online and offline music sources"
AV Magazin 13.04.2018
"Teufel has equipped the One M with powerful technology to get the best possible sound quality out of the compact housing. A real stereo system with three-way bass reflex tuning is used. […] Together with Teufel’s self-developed surround sound technology, Dynamore, the compact speaker then offers an astonishingly wide stereo panorama with astonishing depth. […] Voice reproduction is also excellent, so language and singing always sound authentic and vivid.”

"With the One M, Teufel offers a versatile multi-room speaker with potent sound and a wide range of functions. The corresponding Teufel app offers first-class user guidance, which makes the extensive possibilities of this smart speaker intuitively operable. Teufel's One M is therefore a top recommendation for all music lovers who want a powerful sound system for online and offline music sources.”

Teufel One M review of Testr
"The mid-tones sound excellent and voices are reproduced very clearly"
Testr 17.04.2018
"The Teufel One M already sounds very good with factory settings but can be adjusted with the equaliser according to one's own preferences if necessary. […] The mid-tones sound excellent and voices are reproduced very clearly. The same applies to high frequencies, the four tweeters deliver very well and impress with their detail reproduction. Dynamore technology, which makes this possible, sounds very good. The sound is much wider for it [...]."

"The Teufel One M's maximum volume is enough [...] to power a party sufficiently. If you take it outside, you can certainly hear it a few houses away."

"If you are looking for a streaming speaker equipped with almost all common control options, [...] you’re on the right track with the Teufel One M."

Downloads & support

Help regarding this product
My Bluetooth speaker produces a lesser quality sound with my Windows PC or laptop.
It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
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)
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.
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: 
Reinstalling the firmware in our online manual
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.
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.
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.
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.
