LR-100 Installation - Audio Connections
OUTPUT Audio
The OUTPUT audio section is composed of an OUTPUT audio selection switch, a male XLR balanced audio
OUTPUT connector and two phono unbalanced audio OUTPUT connectors.
OUTPUT Audio Selection Switch
This switch selects what audio is routed to the OUTPUT audio connectors. The switch has three positions:
RX ONLY. In this position, only RECEIVE audio is routed to the OUTPUT. When the transmitter is turned off, the
unit is squelched and the RECEIVE audio is muted.
RX + AUX. In this position, both the RECEIVE and AUXILIARY audio are mixed and routed to the OUTPUT.
RX or AUX. In this position, the OUTPUT audio is either RECEIVE or AUXILIARY audio. When the RECEIVE audio
is squelched (indicated by the illumination of the SQUELCH LED on the front panel), AUXILIARY audio is
routed to the OUTPUT. When RECEIVE audio is not squelched, RECEIVE audio is routed to the OUTPUT.
Balanced Audio Output
When connecting to the XLR balanced OUTPUT, use the pin out shown below. If the output is unbalanced,
either use the unbalanced phono connectors or wire the balanced XLR output as shown below with pins 3
and 1 wired together. The OUTPUT audio has a nominal output level of 0 dBu.

LINE/MIC Switch
This switch reduces the OUTPUT level of the balanced OUTPUT audio only. It does not affect the OUTPUT level
of the unbalanced audio. The OUTPUT audio is reduced by 40 dB to microphone level when this switch is
selected to MIC.
AUXILIARY Unbalanced Audio Input
The nominal input level for the two unbalanced inputs is -10 dBu.
