2.9 Microphone gain reduction
For installations in very noisy aircraft, a reduction in the intercom microphone input gain may be desirable.
The PAR200A has two DIP switches located on the main board that can switch the inputs to a lower gain
setting. PS Engineering installers call for the Service Aid.
