3.6.1 IntelliVox™ VOX-Squelch
No adjustment of the IntelliVox™ squelch control is necessary. Through three individual
signal processors, the ambient noise appearing in all six microphones is constantly being
sampled. Non-voice signals are blocked. When someone speaks, only their microphone
circuit opens, placing their voice on the intercom.
The system is designed to block continuous tones, therefore people humming or whistling
in monotone may be blocked after a few moments.
For best performance, the headset microphone must be placed within ¼ inch of your lips,
preferably against them. 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.
For optimum microphone performance, PS Engineering, Inc. 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.

3.6.2 Volume Control
The volume control knob adjusts the loudness of the intercom for the pilot and copilot
only. It has no effect on selected radio levels, music input levels or passengers' volume
level.
Adjust the radios and intercom volume for a comfortable listening level for the pilot. Most
general aviation headsets today have built-in volume controls; therefore, passenger volume
