The Bosch PRM-USTB multi-source music player with FM tuner, SD card / USB inputs and Bluetooth receiver.

The PRMUSTB is ideal for the provision of background music for public address and commercial audio applications.

Stored music files can be played via the USB interface or SD card input (a 16Gb card is supplied) as an alternative to the FM radio tuner. Music can also be streamed from a Bluetooth enabled device with simultaneous control via the PRM-USTB or playback device.

The media player (SD / USB / Bluetooth) and the tuner can simultaneously play audio to separate output terminals and the volume can be adjusted independently via the volume control buttons on the front panel or the supplied remote control. A combined output has priority for the media player and it automatically switches over to the FM tuner when there is no active media player input.
