Appendix C: Repeater for the SDC 8200 system

A repeater is used to boost the signal on a system cable. When a system cable reaches a length of 100 m, the signal over the system cables becomes too weak.

You can insert a repeater into the system cable to boost this signal.

The repeater features an IN and an OUT socket. The cable from the central unit should be connected to the IN socket and the following daisy-chain of conference consoles should be connected to the OUT socket .

It is also possible to connect a cable daisy-chain with conference consoles to the central unit and – when the cable daisy-chain reaches 100 m – insert a repeater into the daisy-chain.

The DC power supply which reaches the repeater is 30 to 60 VDC straight from the central unit.

The repeater features three LEDs:

UPLINK FAIL LED: lights up when there is no communication with a con- ference console (normally OFF).

DOWNLINK FAIL LED: lights up when there is no communication from the central unit (normally OFF).

POWER SUPPLY LED: lights up when power is supplied to the repeater (normally ON).

For purchasing a repeater, please contact your Sennheiser partner.
