SL MCR DW

The SpeechLine Multi-Channel Receiver with its 2 or 4 channels is the perfect addition to the SpeechLine series. Thanks to its unobtrusive design, the Multi-Channel Receiver can be installed quickly and easily in any room, whether on the wall or ceiling. The device can be operated with a single network cable, thanks to PoE and Dante. Complex analog audio cabling is a thing of the past. The Multi-Channel Receiver also offers a convenient solution for existing installations. Thanks to an integrated auto mixer and the analog mix output, all audio channels can be used simply as a sum signal. The audio mix is also available digitally via Dante, which allows an extension of the existing setup without exchanging the DSP. Due to the bidirectional communication between receiver and transmitter, all settings of the mobile transmitters can easily be made in the Sennheiser Control Cockpit. The receiver's automatic frequency management eliminates the need for manual frequency settings and the automatic interference management guarantees maximum transmission reliability. The user-friendly pairing function ensures a reliable connection between transmitter and receiver. Network integration also makes it possible to remotely control and monitor the receiver via a media control system (e.g. AMX, Crestron). Due to the integrated antennas, a complex antenna installation is no longer necessary.

Specification
  • ARCHITECT‘S SPECIFICATION 

    The multi-channel receiver shall be for use with up to four companion transmitters as part of a wireless RF transmission system. The receiver shall operate in the license-free 1.9  GHz band (frequency ranges shall be from 1,880 to 1,930  MHz, depending on country-specific regulations) and shall use automatic frequency management to find and select the best available frequency in the spectrum and to automatically start the transmission. The receiver shall also incorporate automatic interference management, allowing it to inaudibly and seamlessly change to another frequency if any interference is detected. Time Division Multiple Access (TDMA) and space diversity shall be used to provide for increased transmission reliability. The receiver shall be available as a 2-channel version and a 4-channel version. The receiver shall have a discreet design with fully integrated antennas. With the supplied mounting adapter it shall be mountable to a wall, a ceiling, a tripod or a VESA 100 mount. The receiver shall have two RJ-45 network sockets for power supply (Power over Ethernet: PoE IEEE 802.3af Class 3) and remote control via a control software solution like the Sennheiser Control Cockpit or a media control system (e. g. Crestron and AMX). The two RJ-45 network sockets shall also output digital audio signals to a Dante™ audio network. In addition, the receiver shall feature a 3-pin socket for analog audio output. The 3-pin socket shall be compatible with Phoenix Contact MCVW 1.5-3-ST-3.81 plugs. Control and operation of the receiver shall be performed via the control software solution Sennheiser Control Cockpit. The following features shall be adjustable via the control software: speech-optimized sound profiles, 7-band graphic equalizer for custom audio settings, low-cut filter, automatic gain control (AGC) settings, audio sensitivity settings, audio output level settings, transmitter RF power level, transmitter mute mode and mute switch functionality, RF synchronisation, receiver and transmitter firmware update. Via the control software the receiver shall support automatic or manual mixing of the audio channels to a sum signal. The analog audio output shall output the sum signal. The digital audio outputs shall be able to output the individual channels or the sum signal. The receiver’s AF frequency response shall range from 20 – 20,000  Hz. The dynamic range shall be >  120  dB(A). Total harmonic distortion (THD) at 1  kHz shall be typical 0.1  %. Signal-to-noise ratio shall be >  90  dB(A). The receiver’s RF sensitivity shall be -90  dBm. RF output power of the receiver’s back channel shall be adaptive and up to 250  mW (country-specific). The dimensions shall be approximately 180 x 180 x 45  mm (including the mounting adapter). Weight shall be approximately 560  grams (650 grams with the mounting adapter). Operating temperature shall range from -10  °C to +45  °C (+14  °F to +113  °F). 

    The receiver shall be the Sennheiser SL MCR 2 DW (2-channel version) or the SL MCR 4 DW (4-channel version).
