Fits a standard wall box. The DM837 is built for a standard 86 box and measures 86 × 86 × 38 mm. It sits flush in the wall like a switch panel, and its touch screen shows the functions clearly.

Many music sources. You can play from FM radio, an SD card, a USB drive, Bluetooth 4.1 from a phone, or an AUX input. Supported formats are MP3, WMA, WAV and FLAC.
FM radio with presets. The FM radio searches channels automatically or manually and stores up to 20 channels. Favourite stations are one touch away.

Remote and RS485 control. It supports operation from an infrared remote controller, so you can change the music from across the room. An RS485 interface allows control from an external system.
