Short Description

1.1 MCS 50
The MCS 50 is a self-contained discussion control unit with integrated power supply and processor control for 32 or 64 microphone units. It is a
stand alone unit with multi-function buttons and LC-Display in a desktop housing that is suitable for 19" rack mounting. With this system the
500-series microphone units can be operated. The discussion control unit is delivered with a manufacturer specific configuration. The user, however,
can carry out a configuration of the system by himself. The configuration is controlled by using the multi-function buttons and the LC-Display. For an
extensive configuration, a PC can be connected to the service port and the supplied MCS-Editor software must be used. All functions of the
discussion control unit can be configured using this software. The system operates in a bus mode.

Safety Information

• Never expose the unit to water or excessive humidity. Do not install near swimming pools, spas, in a wet basement or in other excessively
humid environments.
• Never pour any liquids into the unit.
• Do not install or use this unit near sources of high heat, such as radiators, heat registers, flood lamps, spotlights, stoves, or other appliances.
• Always route cables running to the unit where they will not be pinched or cut by heavy or sharp objects.
• Always turn off the power to the amplifier when making input or output connections.
• Verify that the voltage rating of the unit matches that of the AC mains outlet you are to use. If you connect the unit to the wrong voltage,
you may seriously damage it.
• Do not put wires or small objects through any of the ventilation grilles. Electric shock may result.
• This unit needs a sufficient ventilation. Therefore, never cover the ventilation grilles. If you install the unit into a rack leave a minimum distance
of 1 U above and below the unit.

1.2 Microphone Units

For the MCS 50 discussion control unit there are various chairman and delegate microphone units available:
MCS 521 and MCS 523 with loudspeaker.; MCS 501 and MCS 503 for installation into tables.
All microphone units (delegates and chairman) are equipped as follows.
• A connecting cable (3 m long) with a 15-pin Sub-D plug.
• A 15-pin Sub-D socket.
• A mini Mono jack for the connection of recorders, dictating machines etc. (except MCS 501 and MCS 503)
• A cardioid gooseneck microphone.
• A Dual colour LED that illuminates green when the microphone unit is switched on. When the system is operating in the Request-to-Talk mode,
the LED is illuminated red to indicate the registration as a Request-to-Talk. When the microphone is ready, the colour changes to green.
• An illuminated ring to indicate the Ready-to-Talk condition of the microphone unit, when the microphone is switched on.
• On the bottom of the microphone units there are DIP-switches for programming the microphone units (the DIP-switch no. 6 has no function).
Microphone Units with Loudspeakers (MCS 521 and MCS 523)
• Same as above with built-in wide-range loudspeaker.
• On the bottom of the unit there is an individual output volume control for the loudspeaker adjustable from 0 dB to -20 dB this is in addition to
the system level which is controlled via the MCS 50 (installation circumstances may demand lower loudspeaker levels to avoid feedback).
