Sennheiser SpeechLine DW 4-Channel Microphone Receiver – SL MCR 4 DW-3

The Sennheiser SL MCR 4 DW-3 (alternate code 508854) is a 4-channel wireless microphone receiver for the SpeechLine Digital Wireless (DW) system, built for meeting and conference rooms. It provides Dante audio networking, power over Ethernet (PoE) and AES 256 encryption, with an analog mix output. Procure.ae supplies the SL MCR 4 DW-3 in the UAE.

The SL MCR 4 DW-3 receives audio from SpeechLine DW mobile transmitters in the 1880 to 1900 MHz frequency range. Automatic frequency management removes the need for manual frequency settings, and automatic gain control (AGC) adjusts input levels automatically. The integrated automixer combines the audio channels into one sum signal. The receiver is specified with a 20 to 20,000 Hz frequency response, more than 120 dB(A) dynamic range and 0.1 % typical total harmonic distortion (THD).

The receiver mounts on a wall, a ceiling or a microphone stand. A single network cable carries power and audio through PoE and Dante, so complex analog cabling is not needed, and Dante can extend an existing setup without exchanging the DSP. Transmitter settings are made in the Sennheiser Control Cockpit, and media control systems such as AMX, Crestron and Q-SYS Control can monitor the receiver. Compared with the two-channel SL MCR 2 receivers, this model serves four channels.
