DC SOCKET

Low-voltage socket for the power supply of the device. (DC 12 V Plus inside, 1000 mA) Please only use the power adapter included.

Attachment eyelet for the low-voltage power cable (e.g. with a cable tie).

ANTENNA A / B

BNC antenna connector A and B. For optimal reception, please connect the supplied antenna to their respective connectors A and B and

point them upward in "V" formation.

MIX OUT

Balanced audio output with 3-pin XLR socket (mix of signals from channels 1 to 4).

OUTPUT 1 - 4

Balanced individual inputs of channels 1 to 4 with 3-pin XLR sockets.

AUDIO LINK IN / OUT

Mini DIN connectors to daisy-chain the audio outputs of up to ﬁve U500CS4 receivers (1 mini DIN connection cable per device included). The

microphone channels of all slave units of the receivers in the system will be routed to the audio outputs MIX OUT of the master unit. Connect

the audio link OUT socket of the last slave unit in the device chain to the audio link IN socket of the penultimate slave unit etc.. Use the

audio link IN socket of the master unit at the beginning of the device chain.

DATA LINK IN / OUT

Connectors to daisy-chain up to ﬁve U500CS4 receivers (1 data cable per device included). Make sure that the receiver is conﬁgured as

a master or slave unit BEFORE the wiring is done, and that the wiring of the devices forms a "circle", i.e., both data link sockets of all

receivers must be used (example: left socket master -> right socket slave 1, left socket slave 1 -> right socket slave 2, left socket slave

2 -> right socket master). When daisy-chaining the receivers, the microphone station numbers are assigned automatically (Master = MIC

1 - 4, Slave 1 = MIC 5 - 8, Slave 2 = MIC 9 - 12, etc.). MAIN VOLUME, PRIORITY, MODE, THRESHOLD and HOLD TIME are now centrally set

on the master unit.

RS-232

The RS-232 interface allows for controlling the receiver via an external control unit. The command list can be found in the
