For consistent performance, any headset microphone must be placed within ¼-inch of your lips, prefera-

bly against them. (ref: RTCA/DO-214, 1.3.1.1 (a)).

NOTE

It is also a good idea to keep the microphone out of a direct wind path. Moving your head through a vent

air stream may cause the IntelliVox® to open momentarily. This is normal.

The IntelliVox® is designed to work with normal aircraft cabin noise levels (70 dB and above). It loves

airplane noise! Therefore, it may not recognize speech and clip syllables in a quiet cabin, such as in the

hangar, or without the engine running. This is normal.

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.

3.7.2 Mono headsets in Stereo Installation

The pilot and copilot positions work with stereo or mono headsets. All passenger headsets are connected

in parallel. Therefore, if a monaural headset is plugged in to a PAR200 Stereo installation, one channel

will be shorted. Although no damage to the unit will occur, passengers with stereo headsets will only hear

in one ear, unless they switch to the “MONO” mode on their headset.

3.7.3 Intercom Modes (8)

The “ICS” pushbutton switch on the left side of the panel provides the selection

of the three intercom modes.

This button cycles through the intercom modes, from left to right, then right to

left as: ISO, ALL CRW and CRW, ALL, ISO. An LED behind the text shows

which mode is currently active.

ISO: The pilot is isolated from the intercom and is connected only to the aircraft

radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions). Copilot

will hear passengers’ intercom and music, while passengers will hear copilot intercom and music. Neither

will hear aircraft radio receptions or pilot transmissions.

When the audio panel is put into the “Split Mode” (pilot on COM 1, copilot on COM 2), the intercom

automatically enters the ISO mode to prevent confusion with two intercom conversations. The intercom

can be changed to the CRW or ALL mode if desired.
