The SL Rack Receiver DW-4-EU is the stationary receiver core of the Sennheiser SpeechLine Digital Wireless System, with a clear OLED display for setup and operation. It works in the 1880 to 1900 MHz range and lists an audio frequency response of 20 to 20,000 Hz, a dynamic range above 120 dB(A) and a signal-to-noise ratio above 90 dB(A). Bi-directional communication lets users adjust all settings of the mobile transmitters from the receiver side. Automatic frequency and interference management keeps wireless operation convenient and reliable.

Use it in boardrooms, meeting rooms and conference rooms where wireless microphones are paired to a rack-mounted receiver. Ethernet (RJ 45, IPv4 and IPv6) allows network integration, and AMX and Crestron media control protocols let a control system access its settings and statuses. Settings and statuses are also reachable through the dedicated Sennheiser iOS apps. The antennas can be mounted at the back or front, and extension cables for wall mounting are available.
