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 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)).
NOTE
It is also a good idea to keep the microphone out of a direct wind path. Mov-
ing 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 instal-
lation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This
will not only optimize VOX performance, but will improve the overall clar-
ity of all your communications.
Intercom Volume Control (7)
The left side, smaller, inner volume control knob adjusts the loudness of the
intercom for the pilot copilot and passengers. It has no effect on selected
radio levels, or music levels.
The larger, outer volume control knob controls TY91L radio volume.
