Intercom Operation
IntelliVox® VOX-Squelch
IntelliVox® is PS Engineering’s proprietary intercom squelch control.
Through the use of digital signal processors, the each individual mi-
crophone input is monitored, and opens instantly when human speech
is detected. This results in seamless conversations aboard the airplane
for crew and passengers, without annoying syllable clipping or fa-
tigue-inducing noise.
No adjustment of the IntelliVox® squelch control is necessary. There
is no field adjustment. Since this system is designed to block continu-
ous tones, people humming or whistling in monotone may be blocked
after a few moments.
For consistent performance, any headset microphone must be placed
within ¼-inch of your lips, preferably against them. (ref: RTCA/DO-
214, 1.3.1.1 (a)). It is important to have the microphone element par-
allel to your mouth, and not twisted inside the cover.

Note: For optimum microphone performance, we recommend use
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.
