J502 and J503, the default frequency response is flat audio. The pre/de-

Repeater Talk
Through Gain
When a talk through repeater is created by linking the audio path using links
J502 and J503, the repeater will have no talk through gain. If talk through

operation. Then externally configure it to operate as a repeater by linking
the following pins on a 25pin male D-range connector and plugging the
connector into the system connector on the rear panel of the base station.
When configured as described above:
■
The base station will operate as a repeater.
■
The Talk through gain can be set by adjusting the line output level and
line input sensitivity RV500 (BAL IN) and RV503 (BAL OUT) on the
rear panel.
■
The pre/de emphasis links J500 and J501 can be used to set the audio
frequency response.
