3. Connections, controls and indicators

The MCS-D 3643 provides different connections such as the 5-pin / 7-pin Phoenix connector, 5-pin XLR, mini jack
(3.5 mm) and two Lemo connectors to connect external components such as buttons, a gooseneck microphone and
loudspeaker.

 Connector for conference network (Lemo)

The MCS-D 3643 is connected to the MCS-D 200 control unit or CA 4146 power supply unit via Lemo sockets.
Furthermore, the Lemo sockets are used to connect the MCS-D 3643 with one another or other microphone
units.
They are connected in a daisy chain, i.e. the first MCS-D 3643 microphone unit is connected to the MCS-D 200
control unit or to a CA 4146 power supply unit, the second system unit or microphone unit to the first one and
so on.

 Low Bus Power LED

The Low Bus Power LED will illuminate red, when the power in the bus system is too low. Change the system
design (e.g. change the cabling, reduce the number of microphone units, connect another CA 4146 power
supply unit) until the Low Bus Power LED will not illuminate anymore.
