2.9 Microphone gain reduction

For installations in very noisy aircraft, a reduction in the intercom microphone input gain might be desirable.
The PAR200B has two DIP switches located on the main board that can switch the inputs to a lower gain
setting.
Figure 2-3 DIP switches
NOTE: Before changing the intercom microphone gain, we recommend installation of Oregon Microphone
Muff kits as these solve almost all squelch issues.
