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 In-
telliVox® to open momentarily. This is normal.
The IntelliVox® is designed to work with normal aircraft cabin noise
levels (70 dB and above). Therefore, it may not always recognize
speech and clip syllables in a quiet cabin, such as in the hangar, or
without the engine running. This is also normal.
Intercom Volume Control (7)
Turn the smaller volume knob clockwise to increase the
intercom level for the pilot and copilot to
the desired level. The volume knob does
not affect selected radio levels, music
input levels or passengers' intercom vol-
ume level.
Turn the larger knob to set the passen-
gers’ intercom volume to the desired
level.
Since many general aviation headsets have built-in
volume controls, volume also can be fine-tuned at
the individual headset.
Mono Headsets in Stereo Installation
The pilot and copilot positions work fine with either a stereo or a
mono headset. But, since all passenger headsets are connected to-
gether, if one person uses a mono headset, it will cause the other pas-
senger station to become monaural. It will not hurt the audio panel,
and it will return to stereo when the headset is removed.
Intercom Modes (8)
Pushing the “ICS” button cycles through the
three intercom modes, All, Crew (Crw), and
ISO.
In addition, when the audio panel is in the Split
Mode, the Mute button controls the crew inter-
com activation.
In All mode, everybody hears everything, including radios, intercom
and music. The crew will hear Music 1, and the passengers will hear
Music source 1 or 2, depending on the Alternate Distribution method
