3.9 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.

LE-D 10 Charger in MCW-D 10 Case
With the integrated LE-D 10 charger in the MCW-D 10 transport case, it is possible to charge up to 10 microphone unit batteries.
The battery state is indicated on the outside of the case.
The MCW-D 10 transport case can be extended with more LE-D 10 chargers for 10 microphone units each.
Note:
It is normal that the rechargeable batteries are heated up during the charging process.
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. Leave a minimum distance of 20 cm around
the unit.
•
Never place burning objects onto the unit.
4.1 First Use
To achieve a 100% battery capacity all microphone units should have 2 complete charging cycles (charging and discharging) at
least. Only after several charging and discharging cycles the rechargeable batteries will achieve their full capacity.
4.2 Charging Process
1. Connect the charger to AC power and switch it on. The LED on the switch will illuminate.
2. Put the switched-off microphone units into the charging compartments. If microphone units are switched on, they are switched
off automatically. When the microphone units are used again, they must be switched on.
3. The charging process is indicated by the green LEDs on the outside.
a) ___ ___ ___ __ LED is flashing slowly:
b) _________________ LED illuminates permanently:
c) - - - - - - - - - - - - - - LED is flashing very rapidly:
d) LED is off:
e) . . . . . . . . LED flashes rapidly:
f) . - . - . - . - . - . - . - . LED long flash/short flash:
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.
The charging time is around 2 hours when the battery is completely empty.
