Overview of our technologies
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.
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.
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.

Downloads & support
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.
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.
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:
- First remove the Expand's power plug for at least 30 seconds.
- Then, connect the USB stick to the upper USB port of the Expand.
- 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.
- 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.
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.
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
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
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.
USB storage devices with the following formats are supported:
- FAT16 / FAT32
- HFS / HFS +
- EXT2 / EXT 3 / EXT 4
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
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.
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.
- Embed the artwork within the music file
- Save the artwork in the album's folder
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.
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.
- 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 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.
- iTunes Playlists (iTunes Music Library.xml)
- Windows Playlists (*.wpl)
- M3U Playlists (*.m3u)
- PLS Playlists (*.pls)
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.
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.
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.
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.
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
- 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.
Solution: If the resources are offline, simply open the Teufel Reumfeld app on the device from which you would like to stream digital content.
