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).
