Sennheiser SL Rack Receiver DW SpeechLine Digital Wireless Receiver

The SL Rack Receiver is the core of Sennheiser's SpeechLine Digital Wireless system, a half-19-inch stationary receiver with an OLED display for setup and monitoring. Bidirectional communication with paired bodypacks, handhelds, and boundary mics lets an operator adjust a transmitter's settings from the receiver, so nobody has to walk out to a presenter to make a change mid-session.

Automatic frequency and interference management builds a clean RF link without manual coordination, and Ethernet connectivity supports remote control from AMX or Crestron systems as well as Sennheiser's own iOS app. Outputs cover both a balanced 3-pin XLR and two unbalanced RCA jacks, and 256-bit AES encryption protects the link end to end.
