3.3 MCW-D 2673 System Unit
The MCW-D 2673 system unit has been developed for under table installation and in principle it works like the MCW-D 2073
or MCW-D 2071 microphone unit. With one remote microphone button the MCW-D 2673 is used as a delegate microphone unit
and with three remote buttons (microphone, clear and priority) it is used as a chairman microphone unit.
Using the CA 2473 operating unit with display and three further remote buttons the system unit can be also used for voting or
interpreting applications. With these three buttons parameters such as channel, headphone level and overall volume can be
adjusted.
The display is illuminated. This illumination is activated by pressing a remote button and will extinguish after around 10 seconds.
3.3.1 Connections
MCW-D 2673
(1)
(1) Terminal strip 1 for connection of operating voltage, buttons and LED
(2) Terminal strip 2 for connection of headphone, loudspeaker, external microphone and LED ring
Important:
• If the three pins are not used for the headphone socket, the pins "TIP+DET" and "DET" have to be bridged, otherwise
the microphone unit could act as if a headphone were connected and thus receive signals on a wrong channel (LED and
illuminated ring will flash red).
3.3.2 Installation
1. Cut holes into the tabletop for external microphone and external button(s).
2. Install the microphone unit under the table. For fixing the CA 2472 mounting bracket is available as an option.
3. Connect the buttons, operating voltage, microphone, loudspeaker and when required the headphone to the appropriate
connections.
Note:
If the antenna is connected to the system unit directly, it must be at least 12 cm long (1 wavelength).
3.3.3 Switching on/off
The system unit is switched on and off with the connected microphone button.
3.3.4 System Units with Display
If the MCW-D 2673 system unit is completed with the CA 2473-2 operating unit, you can use the microphone unit for
voting or interpreting applications. With these additional three buttons you can adjust channel/language, headphone level and
overall volume. The function "remaining operating time" is not available for MCW-D 2673.
The display is illuminated. This illumination is activated when a button is pressed and will go out after around 10 seconds. For a
detailed description of the individual functions please refer to chapter "3.2.4 Adjustable functions MCW-D 2071 and MCW-D 2073".
