3. Installation of MCS 50 and Microphone units
3.1 Single cable connection
1. Before connecting the MCS 50 to the mains, please
check the supply voltage (refer to chapter 4. “Supply
Voltage”).
2. Address the microphone units as described in the
chapter “1.3 Addressing the microphone units”.
3. Connect the first microphone unit to the line input of
the MCS 50 discussion control unit. The other
microphone units are connected according to the
single cable principle, i.e. the second microphone
unit is connected to the first one, the third to the
second one etc.
4. It is possible to connect up to 32 microphone units in
one line to the MCS 50/32 and up to 64 microphone
units in two lines to the MCS 50/64.
3.2 Branch cabling
1. Before connecting the MCS 50 to the mains, please
check the supply voltage (refer to chapter 4. “Supply
Voltage”).
2. Address the microphone units as described in the
chapter “1.3 Addressing the microphone units”.
3. Connect a 15-pin Sub-D cable to the line input of the
MCS 50 discussion control unit. Connect a CA 1513
triple distributor to the other end of the cable.
Connect two microphone units to the CA 1513 triple
distributor. The last triple distributor in the line
allows to connect 3 microphone units.
4. It is possible to connect up to 32 microphone units in
one line to the MCS 50/32 and up to 64 microphone
units in two lines to the MCS 50/64.
Note:
The total length of the bus cable must not exceed 300 m. Each branch cable in this installation must not exceed 5 m.
Safety instructions
• Make sure that the MCS 50 discussion control unit is always switched off when connecting, disconnecting or addressing the
microphone units.
4. Supply voltage / Power supply
The power supply unit has been developed for an input voltage of 85 V to 264 V AC (50/60 Hz).
Caution:
If the F101 fuse of the integrated power supply (refer also to No. 200 in “Exploded View and Spare Parts, MCS 50 Discussion Control
Unit”, page 48 to 49) is defective, you should replace the whole part. A different fuse with a higher value than 6.3 A can destroy
the power supply.
Please contact your beyerdynamic-dealer.
