15) MIC GAIN:
Is for regulating microphone sensitivity, when using a microphone other than
the one supplied with your PRESIDENT JACKSON ASC. (pre-amplified).
The normal setting of this knob is fully clockwise.
16) 6-PIN MICROPHONE PLUG:
This plug is situated on the front panel, thereby making it easier to set the
equipment into the dashboard. See the cabling diagram on page 46.
17) PTT (push to talk):
Depress this knob to transmit a message and release to listen to an incoming
communication.
