Frequently asked Questions

The model number of your sonoro device can be found on the back of the device where it is written “Product No”.

Just click hier and download the instruction manual of your sonoro device as a Pdf.

No, unfortunately we have no shop at our head office. Have a look around in our online shop and order your sonoro product comfortably from home. Or choose your device here and have it delivered to a dealer in your neighbourhood. There you can have a look at sonoro´s products and get some advice – without obligation.

Unfortunately, currently our audio systems do not support playback of audio or video files on DVD or Blu-ray media.

Reduce the distance between the devices to less than ten meters and make sure you have a barrier-free transmission.

Follow the operating instructions for your sonoro device. Check whether the Bluetooth function on your smartphone or tablet is switched on. Check whether one of your devices is already connected to another Bluetooth source or another Bluetooth receiver.

We recommend that you test the placement and orientation of your sonoro device at various locations in order to optimize it specifically for your room environment. To do so, place your sonoro device on a stable and level surface. On smooth surfaces such as glass, marble or polished wood, the device can move due to the vibration of the speakers. Therefore you will not get an optimal sound.

The backup battery ensures that the time in your sonoro device continues to run in case of a power failure. However, the time is not displayed during the power failure. As soon as your device is reconnected to the power supply, the current time is displayed.

Almost all sonoro audio systems have a USB port that can be used to charge smartphones. Unfortunately, it is not possible to play music via the USB port of the iPhone/iPod.

With all the products from the SMART LINE you have the possibility to use Spotify directly on your device. The use of other streaming services is easily possible via your smartphone or tablet if you use the Bluetooth or Multiroom function. With our CLASSIC LINE audio systems, you can also use streaming services via your smartphone or tablet by using the Bluetooth.

There are many causes that can lead to a faulty radio reception. Sometimes the topography or the ambient situation makes the reception difficult. Therefore, please check the following points:

1 Please check the alignment of the antenna. Tips for perfect alignment can be found here in the operating manual of your device.
2. Test the device in a different location.
3. Use www.fmscan.org to check whether the selected transmitter is available in your area.

This may be due to your Internet connection as well as to the selected Internet station. So please check your internet connection first and test if the jerking also occurs with other stations.

When resetting to factory settings, all stored transmitters are deleted. The transmitters must also be stored again after a firmware update.

Our SMART LINE products usually receive updates automatically via the Internet. Further information and instructions can be found here in the operating manual of your system. Our products from the CLASSIC LINE do not require any further updates after purchase, as there is no Internet access available here.

In rare cases it may happen that a USB stick cannot be read correctly by every port. Check whether your USB stick is formatted in FAT32. Therefore, please test if other USB sticks work and repeat the connection process several times to restart the reading process.

All sonoro audio systems from the SMART LINE have a Spotify ID. Once you have used Spotify with your audio system for the first time, your device is connected to your Spotify account. This is independent of whether or not you are nearby with your smartphone. This means that you can also activate and play your Spotify at home while you are on the move. Please pay attention to the playback source on your smartphone within the Spotify app.

To automatically update the local time, simply select the “Radio” source. In this way the summer and winter time is always updated. Of course, a manual changeover is also possible. When synchronising via the Internet, you must always set the summer and winter time manually. Please read the operating instructions of your device here.

Your sonoro SMART LINE products can be controlled both in a LAN and in a WLAN network with the UNDOK App. Your devices are set by default for use in a WLAN network. If you want to connect your devices to each other in a LAN network, this can be set under “”System settings > Network > Manual settings > Cables > DHCP active””. Please note, however, that it may be more time-consuming to connect all devices via the UNDOK-APP in a LAN network.

With the free UNDOK App you can group up to 5 devices and use them simultaneously. In total you can manage up to 16 devices in the app. You can also find the UNDOK user manual here.

Information about some interference with the Internet radio reception

Currently, the Internet radio and podcast services may be disrupted on our music systems. Unfortunately, these disruptions are caused by a third party supplier and are therefore beyond our direct control. In addition to sonoro music systems, millions of other Internet radio in Europe are affected.

We are working closely with the service provider to implement a solution in the form of an alternative service and we have been receiving content from another Internet radio provider since May 7, 2019 / 21:30 hours. Given the huge amount of data to migrate as soon as possible, the server structure was not stable during the first few hours of the service’s implementation. The situation has been stabilized and we assume that these problems have now been largely resolved.

If your audio system no longer receives Internet radio, proceed as follows:

Disconnect your sonoro music system completely before turning it on again (for PRESTIGE and MEISTERSTÜCK use the switch button on the back of the unit, for all other units, remove the cable from the AC adapter). Then wait for few minutes to reconnect the music system.
If this is not the case, it is recommended to perform a factory settings reset or possibly reset your network router. Please refer to your user manual.

The old web portal www.wifiradio-frontier.com is no longer available and you cannot use it to create your own account and/or add your own stations. If you want a station to be added to the database, please use the following link to generate a ticket (choose New radio station or New podcast under “Template”): https://support.wifiradiofrontier.com/portal/newticket

Due to the change of supplier, favorites must be saved again. In addition, you may notice minor changes in the menu structure of your device.

We apologize for any inconvenience caused by these changes. We have implemented these changes in order to ensure the continuity of the service. Even if the scenario of a change of supplier has been intensively tested in advance, it can initially lead to reduced service stability.

“Your MEISTERSTÜCK has an eject lock. In CD active mode, please press the “”Stop”” button for three seconds, then release it and briefly press the “”Eject”” button. This activates or deactivates the eject lock (CD locked / CD unlocked).
“

Please read the operating instructions here.

We are legally obliged to design our audio systems in such a way that they can switch off after 20 minutes in an inactive state. You can check this function under “System settings” > “Inactive standby” and set it yourself.

You can connect active loudspeakers to your MEISTERSTÜCK via the line-out connection. The use and control of passive loudspeakers is only possible with the help of an additional amplifier.

One of the main functions of your MEISTERSTÜCK is to connect to the Internet in order to receive Internet radio stations available worldwide. There are three ways to disable the Internet function:

1. Navigate to “System settings” > “Network” >”Keep network connection” and select the option “No”
2. Navigate to “System Setup” > “Time/Date” > “Auto Update” > “Update from Radio” and perform a system update.
3. Disconnect the device from the power supply, reconnect it and check the function.

When resetting to factory settings, all stored stations are deleted. The stations must also be stored again after a firmware update.

Yes, saving favourites with the remote control is possible with all sonoro products. Up to 40 radio stations can be stored as favourites on your MEISTERSTÜCK. Up to nine favourites can be stored via the MEISTERSTÜCK remote control. If you want to store even more stations, you can do this directly on your MEISTERSTÜCK. Select your favourite station, press the “FAV” key for longer than three seconds, then the favourite memory appears. Select a free seat and confirm this by pressing the speaker control button. You can call up all favourites via the number field on your remote control. Please also read the operating instructions for your MEISTERSTÜCK here.

With the free UNDOK App you can group up to 5 devices and use them simultaneously. In total you can manage up to 16 devices in the app. You can also find the UNDOK user manual here.

Such humming can have many different causes.
1) For example, the connecting cables used between your MEISTERSTÜCK and your external speakers may not be optimally shielded or defective. Check the cables and replace them if necessary. 2) Also the different grounding of the devices could be the problem. Such humming can occur when the devices are connected to different phases or circuits. If your MEISTERSTÜCK is connected via the house antenna, try the included antennas. If you still prefer to use the house antenna, then the use of a so-called “”jacket current filter”” could possibly help. Connect your devices to the same circuit or socket.

Use the remote control to switch your MEISTERSTÜCK to optical input. To do this, your TV must also be set to the optical output. If your TV set supports this, set “PCM” there. Please read the operating instructions for your TV set.

Bitte lesen Sie dazu die Bedienungsanleitung Ihres BT-Kopfhörers genau durch. Je nach Kopfhörer und Hersteller gibt es verschiedene Wege, den BT Kopfhörer auf “Pairing” einzustellen. Bitte achten Sie darauf, dass Ihr Meisterstück immer auf “Kopfhörer paaren” eingestellt ist ( “SETUP”-Taste , dann Bluetooth Kopfhörer > Kopfhörer paaren ): Achten Sie darauf, dass keine weiteren verbindungsbereiten Empfangsgeräte in der Nähe sind.

Please tighten the antenna as described in the operating instructions. Then take an 11 mm open-end wrench and tighten the locking screw clockwise by hand. Tightening the screw too tightly could overtighten the screw.

Take a look at the operating instructions of your MEISTERSTÜCK here. Further questions will be answered there. Or contact our service department at support@sonoro.de

If you register yourself and your Meisterstück here, you will receive a free warranty extension for another year from the date of purchase for your Meisterstück. Your data will be stored and processed by us in accordance with the current data protection guidelines.

1. Navigate to “”System settings”” > “”Network”” >””Keep network connection”” and select the option “”No””.

2. Navigate to “”System Setup”” > “”Time/Date”” > “”Auto Update”” > “”Update from Radio”” and perform a system update.

3. Disconnect the device from the power supply, reconnect it and check the function. “

Your sonoro SMART LINE products can be controlled both in a LAN and in a WLAN network with the UNDOK App. Your devices are set by default for use in a WLAN network. If you want to connect your devices to each other in a LAN network, this can be set under “”System settings > Network > Manual settings > Cables > DHCP active””. Please note, however, that it may be more time-consuming to connect all devices via the UNDOK-APP in a LAN network.

Yes, saving favourites with the remote control is possible with all sonoro products. Up to 40 radio stations can be stored as favourites on your PRESTIGE.

Select your favourite station, press the “FAV” key for longer than three seconds, then the favourite memory appears. Select a free seat and confirm this by pressing the speaker control button. You can call up all favourites via the number field on your remote control. Please also read the operating instructions for your PRESTIGE here

Such humming can have many different causes.
1) For example, the connecting cables used between your PRESTIGE and your external speakers may not be optimally shielded or defective. Check the cables and replace them if necessary. 2) Also the different grounding of the devices could be the problem. Such humming can occur when the devices are connected to different phases or circuits. If your PRESTIGE is connected via the house antenna, try the included antennas. If you still prefer to use the house antenna, then the use of a so-called “”jacket current filter”” could possibly help. Connect your devices to the same circuit or socket.

Use the remote control to switch your PRESTIGE to the optical input mode. To do this, your TV must also be settled to the optical output. If your TV set supports this, set “PCM” there. Please read the operating instructions for your TV set.

Please read the operating instructions of your Bluetooth headphones carefully. Depending on the headphones and manufacturer, there are different ways to set the bluetooth headphones to “Pairing”. Please make sure that your PRESTIGE is always settled to “pair headphones” (“SETUP” button , then Bluetooth headphones > pair headphones ): Make sure that there are no other receivers around that are ready for connection.

Please tighten the antenna as described in the operating instructions. Then take an 11mm open-end wrench and tighten the locking screw clockwise by hand. Tightening the screw too tightly could overtighten the screw.
