Intercom Operation
IntelliVox
® VOX-Squelch
IntelliVox® is PS Engineering’s proprietary intercom squelch control.
Through the use of digital processors, each microphone is monitored, and
opens instantly when human speech is detected. This results in seamless con-
versations aboard the airplane for crew and passengers, without syllable clip-
ping or fatigue-inducing noise.
No adjustment of the
IntelliV ox
® squelch control is necessary. There is no
field adjustment. The system is designed to block continuous tones, therefore
people humming or whistling in monotone may be blocked after a few mo-
ments.
For consistent performance, any headset microphone
must
be placed within
¼-inch
of your lips, pr efer ably against them. It is impor tant to have the
microphone element parallel to your mouth, and not twisted inside the cover.
Note: For optimum microphone performance, we recommend use of a Mi-
crophone Muff Kit from Oregon Aero (1-800-888-6910,
www.oregonaero.com
). This will not only optimize VOX performance, but
will improve the overall clarity of all your communications.
You should also keep the microphone out of a direct wind. Moving your
head through an air stream may cause the
IntelliV ox
® to open momentarily.
