DESCRIPTION
Digital control unit for an almost unlimited number of wireless
microphone units with loudspeaker. Integrated diversity combiner
for a maximum of 3 or 9 smart link receiving modules. Depending
on the version of the MCW-D 50 control unit a maximum of 3 (e.g.
2 delegates and 1 chairman) or 9 microphone units (e.g. 7 delegates
and 2 chairmen) can be activated simultaneously.
There is a constant status inquiry, monitoring or control due to the
data connection to the microphone units. Individual microphone
units can be activated via the RS 232 serial interface. The complete
discussion system can be switched off via a control command or by
pressing the “Stand-by” button on the front. The 9 LEDs on the
front indicate the assigned transmission channels of the micro-
phones. To increase the security of the system, the control unit can
operate in the “security mode” i.e. the control unit only operates
with microphone units which have the same encryption key. In
addition to this, the audio data are encrypted.

ARCHITECT’SSPECIFICATIONS
Central control unit of a wireless digital discussion system. Specific
DSSS modulation (Direct Sequence Spread Spectrum) ensures a high
noise immunity in the 2.4 GHz frequency band world-wide
approved. A virtually unlimited number of microphone units can be
controlled. Up to 9 data channels allow the use of max. 9 audio-
voice streams. Depending on the version of the control unit
a maximum of 3 or 9 microphone units can be allocated
simultaneously. Automatic audio channel allocation. Diversity
technology ensures a high transmission safety. Operation modes:
manual: each participant can switch his microphone on or off; voice-
controlled allocation: as soon as someone speaks into the micro-
phone it is switched on; override: when a microphone is activated,
the first one will be switched off; Push-To-Talk: the microphone
button must be held down while the participant is speaking. The
complete system can be switched off with the stand-by button on
the front or via a control command of the serial interface or the
network connection. RS 232 serial interface / Ethernet interface for
system configuration, PC or media control system. Audio input for
external signals. All connections on the rear are plug-in types: audio
master output (3-pin XLR, balanced, RCA, unbalanced), audio input
(3-pin XLR balanced, RCA, unbalanced), antenna input A/B and
antenna output (N-RF). 19" desktop housing, 2 HU. Dimensions
(WxHxD) 440x88x310mm. Weight: 4.7 kg.
