Rear Panel Description; Installation - Lectrosonics QUADUHFD Operating Instructions And Troubleshooting Manual

SERIAL/FREQUENCY LABEL - This label, located on the rear of the housing on each distribution module, indicates
the serial number and the RF passband of the distribution module. IMPORTANT - The receivers installed in the unit
must fall between the passband indicated on the label. Serious signal loss results if the receiver frequencies are
outside the RF passband.
POWER XLR CONNECTOR - This 4 pin Switchcraft D4M connector is the power input jack for both the AC charger
and for external 12VDC power. Pins 1 and 4 are used for external 12 VDC input. Pins 2 and 3 are utilized for 15VDC
charging with the CH80 charger.
POLARITY DIAGRAM - The polarity diagram on the lower panel indicates the wiring connections for the 4 pin XLR
power connector. Use this diagram when connecting your own external power source to the system.
POWER LEADS - These connectors provide power for the individual receivers. Insert the connectors into the jack
provided on each receiver.
INSTALLATION SCREWS - The two large counter-sunk phillips head screws in the central area between the receiv­
ers are used for receiver installation and removal. See the following page for further instructions.
RECEIVER AUDIO OUTPUT - Supplies a balanced, low impedance output at microphone or line level. The audio
signal is output on pins 2 and 3, while pin 1 is ground. The output level of this jack is controlled by the OUTPUT
control on the front panel of the receiver and by the range switches in the battery compartments of the receivers (see
receiver instruction manuals). The connector is a standard XLR type.
RECEIVER POWER IN JACK - Connects to the POWER LEAD for powering the receiver from the QUADUHFD
source.
