2. Do not place the MCW-D 100 control unit near digitally controlled equipment.
3. Connect the receiving antennae to the antenna inputs A and B (5) using the appropriate adapter. For stand-alone-operation we
recommend using the CA 2411 angled rod antenna and the CA 2444 N(HF) Male - SMA Female adapter.
4. Connect the transmitting antenna to the antenna output (12). For stand-alone-operation we recommend using the CA 2411
angled rod antenna and the CA 2444 N(HF) Male - SMA Female adapter.
5. There must be an unobstructed path between the microphone units and the antennae. The range is around 50 m. For
optimum range the surface of the table is important, wood or plastic tables are ideal, but metal tables can cause interferences
and reduce the range.
6. Connect the XLR (10) or RCA (14) master output to the input of a mixing console/amplifier.
7. Connect the MCW-D 100 control unit to the mains (7). The internal power supply unit of the control unit can adjust automatically
between 110 V and 240 V.
8. Switch on the MCW-D 100 with the On/Off-switch (8) on the rear. The Power LED (1) on the front will illuminate green.
9. Depending on the configuration of the MCW-D 100 control unit 5 or more channel-LEDs will illuminate green (standard: 5 channels).
10. When mounting the MCW-D 100 control unit into a 19"-rack housing leave 1 HU for a ventilation panel.

2.2 Setting up
The microphone units have no separate on/off switch. They are switched on and off with the microphone button. By pressing
the button briefly, the microphone unit is switched on. The LED (7) flashes for a moment and the LED (2) on the rear is illuminated. By
pressing the button for more than 2 seconds the microphone unit is switched off and the LED (7) will illuminate twice red/green
briefly. Using the controller software (standby button) the microphone unit can be switched off via the control unit. Furthermore, the
microphone units are switched off automatically, when they do not receive a data signal from the control unit for more than one
minute.
Important:
If the microphone unit is out of range of the MCW-D 100 control unit the LED (7) will flash red. After one minute the microphone unit
will switch off automatically.
Switching on
Switch on the microphone unit by pressing the microphone button briefly. The green operating control LED (2) on the rear will
illuminate.
The microphone units have an integrated rechargeable battery allowing an operating time of at least 10 hours in conference mode.
As soon as the capacity is too low for satisfactory operation, the operating control LED (2) will flash. The remaining time of
operation is around 30 minutes. The decreasing battery voltage is also signaled by the MCW-D 100 control unit at the RS 232 socket
and can be evaluated by an external media control system.
Manual Mode
Press the microphone button (8) to switch the gooseneck microphone on or off.
The LED (7) is illuminated green: The integrated transmitter is adjusted to a free frequency and switched on.
Red ring of the gooseneck
microphone is illuminated: The microphone is ready for talking.
Using the standard version of the MCW-D 100 control unit 3 delegates and 1 chairman can speak simultaneously. Using
additional PCBs inside the MCW-D 100 up to 6 delegates and 1 chairman can speak simultaneously.
Important:
If the number of open microphones is reached, a microphone can only be switched on manually when another
microphone unit has been switched off.
Request-To-Talk Mode
The mode is only possible in conjunction with a PC using the MCW-D Controller software or media control system (AMX/Panja®,
Crestron®etc.). The request-to-talk is registered in the system by pressing the microphone button of the microphone unit. The allocation is made by the operator at the PC or touchscreen of the media control system. The LED (7) is illuminated to indicate the requestto-talk. If you press the microphone button again the request-to-talk is cleared. The LED (7) goes out.
2.3 Auto-Off-Function
The delegate microphone units have a power saving auto-off function, i.e. if no-one speaks into the microphone for more than
20 seconds, the microphone unit switches off automatically. The auto-off-function has been deactivated at the factory. The response
threshold and the time after which the microphone switches off can be adjusted with a programming device or PC using the Editor
software. The illuminated ring of the gooseneck microphone will flash 5 seconds before the microphone unit is switched off.
2.4 Addressing the Microphone Units / Serial Number
At the factory each microphone unit is programmed with a different identity number so that the MCW-D 100 control unit can
control them individually. This number is printed on the bottom.
When you subsequently order more microphone units later, please inform the supplier of your current identitiy numbers to avoid
duplication.

2.5 Documentation Output
A headphone (e.g. DT 301) can be connected to the documentation output (4). We recommend a min. impedance of 200 Ω.
ATTENTION: This connection has been covered, because at present special headphones can be connected only. If you need
this connection please contact beyerdynamic.
2.6 CA 2455 External Power Supply
The MCW-D microphone units can be powered with the CA 2455 external power supply unit which can be connected to the
multi-function socket (1). The DC-voltage should be 18 V DC (±0.5 V), current max. 180 mA, residual hum < 20 mV.
Important:
Connect and disconnect the external power supply only when the microphone unit is switched off.
If the microphone unit is powered by the DC-power supply first and when the power supply is switched off, the microphone unit will be
powered by the integrated battery until it is nearly empty. The microphone unit switches off automatically to avoid an exhaustive
discharge.
But if the switched on microphone unit is powered by the battery first and then connected to DC-power, the external power supply will
power the microphone unit.
2.7 Maintenance of the MCW-D Microphone Units
For cleaning the MCW-D microphone units when they are slightly dirty (finger prints, dust, jam or juice) use a soft, damp cloth,
sponge or brush and a liquid cleaning agent. Before cleaning the surface it must be moistened thoroughly. Afterwards it must be
cleaned with clear water. Make sure not to allow any water to enter the unit. For dirt caused by mineral oils and fats, animal and
vegetable fats use spirit, isopropyl alcohol or benzine.
For dirt caused by ballpoint pens, typewriter ribbons or carbon paper use isopropyl alcohol or spirit.
Clean the supplied pop shield with clear water. Make sure that it is completely dry before you put it on the microphone again.
2.8 Safety Code
Using the MCW-D Editor software or the MCW-D 1003 programming device a safety code can be entered for the MCW-D micro-
phone units and the MCW-D 100 control unit within one system. This will increase the safety against unauthorised listening. For a
detailed description please refer to the appropriate manuals.

Note
If an error has occured, try to start the charging process once again. If the LEDs are still flashing rapidly, please contact your
beyerdynamic dealer.
4.2 Forming Mode
The LE-D 10 charging units are equipped with a forming mode for the rechargeable batteries inside the microphone units. The
batteries are formed and charged at the factory. If you have not used the microphone units for several months, you should form the
batteries before you set up the microphone units. Do this as described in the following:
• First of all remove all microphone units from the charging compartments.
• After switching on the charger press the buttons in the bottom of the two furthest charging compartments (next to the contact
pins in the round gap).
• Pressing one of these buttons will activate the forming mode for 5 charging compartments. The LEDs will flash rapidly.
• Then put the microphone units into the charging compartments. The LEDs will flash short and long.
• When the green LEDs are permanently on, then the battery is full.
Caution:
Only form empty or partly discharged batteries, but never full batteries!
Do not switch off the charging unit during the forming mode, as this will interrupt the forming mode.
The forming mode will be terminated automatically when the microphone units are fully charged or when the charger is switched
off.
5. Battery Charging with external Charger
The MCW-D microphone units can be also charged with the CA 2456 external charger which is connected to the multi-function
socket (1).
Important:
The automatic switching off of the microphone units when they are charged is not possible with the CA 2456. Therefore, the
microphone units must be switched off manually (or via the MCW-D 100 control unit) before charging.
