Powering MCW-D 2673

(1)
• The microphone units have an integrated rechargeable battery (except
MCW-D 2xxx DC versions) allowing an operating time of at least 9 hours in
discussion 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 or 60 minutes, depending on the
configuration with the MCW-D 200 Editor software.
• The decreasing battery voltage is also signaled by the MCW-D 200 control unit
at the RS 232 or LAN interface and can be evaluated by an external media
control system.
• The MCW-D microphone units (except the MCW-D 2xxx DC versions) can be
powered with the CA 2455 external power supply unit which can be
connected to the multi-function socket (1).
• If another power supply unit is to be connected, the DC-voltage should be
18 V DC (±0.5 V), current max. 180 mA, residual hum < 20 mV AC.
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 micro-
phone unit switches off automatically to avoid an exhaustive
discharge.
• The microphone unit is not powered automatically, when the
CA 2455 external power supply unit is connected to it. The micro-
phone unit has to be switched on after having connected the power
supply unit.
• The MCW-D 2673 system units are powered via DC voltage (between 14 and
20 V) that is connected to the terminal strip (1).
