The half 19" stationary SL Rack Receiver DW is the easy-to-integrate core of the SpeechLine Digital Wireless System. It features a clear visible OLED display for easy setup and operation. Thanks to the bi-directional communication all settings of the mobile transmitters can be adjusted from the receiver side.

The automatic frequency and interference management allows convenient and reliable operation. Thanks to the easy-to-handle pairing process, the transmitter and receiver are securely linked. Via network integration all settings and statuses are also accessible via AMX/Crestron media control protocol and the dedicated Sennheiser iOS Apps. The antennas can be either back or front-mounted. Furthermore, extension cables for wall mounting are available.
