You will hear a confirmation sound when both devices are synchronized and the "BT" LED function indicator (15) will stop flashing and will glow as usual.

TWS (True Wireless Stereo) function

This option enables to connect another Music Box 9 wirelessly within a distance range of 10 m to hear music with twice as much power and to create a stereo sound system made up of two different channels: left and right.

Switch on both Music Box 9 and select Bluetooth mode, press the TWS connection button (13) of each speaker and you will see that the TWS indicators start blinking. Once both devices have been connected correctly, you will hear another confirmation sound and the TWS indicators will stop blinking.

Press and hold once again the TWS connection button (13) of the secondary speaker for a few seconds to disable TWS connection.

Use the master speaker to control playback functions while True Wireless mode is enabled. The secondary speaker will only allow you to adjust the volume. If you adjust any of the functions, the changes will always apply to both speakers. This means that if you turn up the volume of any of the speakers, you will be turning up the volume of both of them.

Important: In order to set up channels and disable the TWS connection, you have to press the TWS connection button (13) of the speaker that shows that the Bluetooth Function Indicator (15) is on.

Once your Music Box 9 is in playback mode, you will be able to control playback functions from the speaker itself. Press Volume + (3) or Volume - (2), Next (6) or Back (4) and Play/ Pause and Call control (5) to perform different playback actions. You will hear a warning sound when reaching the maximum and minimum volume levels.

Synchronizing your Music Box 9 with your smartphone allows you to control your calls from the speaker.

When receiving a call, the song you are listening to will stop and the ringing tone will sound instead. Press the Play/ Pause and Call control button (5) to answer an incoming call and press it once again to hang up. The song will automatically resume afterwards.

Press and hold the Play/ Pause and Call control button (5) when receiving an incoming call to reject it. Press and hold the Play/ Pause and Call control button (5) while Bluetooth mode is enabled to redial telephone numbers.

If you receive an incoming call while TWS function is enabled, playback will pause and you will only be able to hear the voice of the person who calls through the master speaker.

Audio input

You can also enjoy music playback on your Music Box 9 by connecting your music player to the Audio-In (8) by means of the provided audio cable with 3.5 mm jack connector. This mode appears on one side and is indicated as "AUX".

NOTE: It is not possible to control music playback from the speaker while you are using this mode. In order to control playback functions you will have to use the music player that you have connected.

FM radio function

In order to use the FM radio function, it is necessary that you first carry out a search of all stations available. The radio stations will be saved to the speaker internal memory. Therefore it is not necessary to carry out a new search each time you switch it on. You will only have to carry out a new search if you place the device in a new location or if you change the frequency of the saved radio station.

In order to carry out a search of all radio stations, press the Change function (14) button until the FM mode appears on screen. The "FM" LED function indicator (15) will light up when the radio funtion is selected. Press and hold the Change function button (14) for 2 seconds. The "FM" LED function indicator (15) will flash while carrying out the search. Once the process is completed, the LED will glow as usual. The process can take a few minutes.

You can use the provided audio cable with jack connector as an antenna cable to improve the signal. In order to do so, connect the above mentioned cable to the AUX port, return to FM mode and carry out a new seach of radio stations following the steps that have been explained before.

Press and hold Next (6) or Back (4) to select the radio station that you prefer. Radio stations will appear in the order in which they were saved. Press Next (6) or Back (4) to tune the selected frequency.

Note: The power adapter used to charge the device may interfere with the FM radio signal. We recommend to maintain a distance of 50 cm between the power adapter and the speaker if FM radio function is enabled and you are charging the battery simultaneously.

External storage

Insert an external USB stick or a microSD card into the corresponding slots, (9) and (10), to play MP3 or WAV files. The Music Box 9 will enable this playback mode automatically. Music playback will start in a few seconds once the external storage unit has been read. Do not remove the storage unit while the reading process is in progress.

If you turn off the Music Box 9 while the device is playing the files of the external storage unit, the internal memory will save the moment when you paused playback. If you insert the same removable card or stick once again, playback will resume from the point at which it stopped.

To move to the previous or the following track, press Next (6) or Back (4). You can also move to the next folder of your microSD card / USB stick. To do so, press and hold the Change function (14) button for a few seconds.

Press and hold Next (6) or Back (4) while the device is playing a song to fast forward through it or to rewind it. Playback will resume when you release the button.

Important: We recommend not to remove the external storage unit while the reading process is in progress. Before doing that, please change mode or turn off the speaker.
