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, 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 mo-

mentarily. 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.
