SL MCR 2 DW-3

A two-channel receiver for SpeechLine Digital Wireless rooms

The Sennheiser SL MCR 2 DW-3 is the two-channel member of the SpeechLine DW receiver family, designed to take signals from wireless microphone transmitters and pass them into a room's audio system. The white unit measures 180 x 180 x 45 mm including its wall mount and weighs 560 g, so it can be fixed to a wall, mounted above a ceiling or clamped to a microphone stand without dominating the room.

This variant operates in the 1880.000 - 1900.000 MHz frequency range. The other variants in the family list their own ranges, and some sit close together, so check the exact range against the transmitters you already own before ordering.

Connectivity: one cable for power, control and audio

Power over Ethernet and Dante let the receiver run from a single network cable, which reduces the bundles of analog audio runs that older rooms rely on. The unit provides two RJ-45 Dante sockets with primary and secondary connections, so the digital mix can travel over the network to a Dante-based DSP. For rooms that still use analog, a 3-pin analog mix output delivers the sum of all channels. Remote control and monitoring are possible through the Sennheiser Control Cockpit or a media control system such as AMX, Crestron or Q-SYS Control.

Where it fits in Qatar

A ministry or bank boardroom in West Bay is a typical case: two wireless microphones at the table feed the room's conferencing system, and the Dante output lets meeting audio reach an existing DSP without rewiring. In Education City, a seminar room or small lecture theatre can use the automixer to combine two presenters' microphones into one clean signal for recording or for a link with a partner site abroad. Hotel ballrooms in The Pearl or Msheireb, with changing layouts between events, benefit from the wall, ceiling and stand mounting options.

Planning the installation in Qatar's climate

Qatar summers can push temperatures above 45°C, and the rated operating range of this receiver stops at +45°C. Position it inside air-conditioned rooms or a ventilated cabinet rather than an unventilated ceiling void or a hot plant space, and confirm the location with the SmartRooms Qatar team during the free site survey. Plan the network route for PoE and Dante, confirm the transmitter band, and use the drilling template and wall mounting plate supplied in the box. Fixings are not listed in the box contents, so confirm them at the survey.
