The compact but robust SL Bodypack DW is optimised for speech in presentations or lectures where every word matters. It is compatible with all Sennheiser mircophones such as SL Headmic 1 or MKE 1. Thanks to bi-directional communication between transmitter and receiver, no settings need to be adjusted on the transmitter.

The automatic frequency and interference management allows convenient and reliable operation. The LC display provides the link name, battery status and reception quality. The easy-to-access mute-slider makes the use of the microphone very convenient. The SL Bodypack DW comes with a rechargeable Li-Ion battery with external charging contacts - for easy charging with the CHG 2 - and a USB socket.
