today have built-in volume controls; therefore, volume also can be further ad-
justed at the individual headset.
For optimum microphone performance, PS Engineering recommends
installation of a Microphone Muff Kit from Oregon Aero (1-800-888-
6910). This will not only optimize VOX performance, but will improve the
overall clarity of all your communications.

Mono headsets in Stereo Installation
All passenger headsets are connected in parallel. Therefore, if a monaural
headset is plugged in to a PMA8000 Stereo installation, one channel will be
shorted. Although no damage to the unit will occur, all passengers will lose
one channel, unless they switch to the “MONO” mode on the headset. PS En-
gineering modifies headsets to add stereo capability, using high-fidelity speak-
ers. Contact factory for details.
Intercom Modes (8)
The “ICS” pushbutton switch on the left side of the panel provides the selec-
tion of the three intercom modes. The description of
the intercom mode function is valid only when the
unit is not in the "Split" mode. Then, the pilot and
copilot intercom is controlled with the Mode but-
ton.
