A 4-channel SpeechLine receiver with two available Dante ports and integrated antennas, the SL-MCR-4-DW-4 blends seamlessly into any decor and delivers Sennheiser quality to your conference and communication system.

The SL-MCR-4-DW-4 supports Power over Ethernet (PoE) and Dante transmission so all of your audio, communication, and power can travel over a single network cable. No mismatched connectors or bulky hard to run analog cables are needed for integration, one Ethernet cable, and you're set. And if you're adding to an existing system, an auto mixer allows for all audio channels to be used as a sum signal available at the analog output, or digitally via Dante. This feature creates an extension of the existing setup without exchanging the DSP.

Automatic frequency management replaces manual frequency settings, and auto-pairing ensures transmitters can find their receivers, leaving you free to focus on other things.

Network integration also makes it possible to remotely control and monitor the receiver via a media control system like AMX or Crestron. And when you're passing sensitive information on a network, it's a plus knowing Sennheiser had your back and designed AES 256 encryption into the SL-MCR-4-DW-4.

It's easy on the eyes too. At 1.7" thick and blessed with internal antennas the SL-MCR-4-DW-4 mounts unobtrusively to a wall, ceiling, or mic stand with no complex antenna installation necessary.

Build your new com system or upgrade your current one with the SL-MCR-4-DW-4.
