NOTE
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 momentarily. This is normal.
The IntelliVox® is designed to work with normal aircraft cabin noise levels
(70 dB and above). It loves aircraft 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.
Push to talk intercom (PTT ICS)
Pressing the intercom volume knob (ICS VOL) will place the system into
the Push-to-talk (PTT for Intercom use) mode. This will disable the voice
activation (VOX) and require that the external push to talk intercom buttons
for each position be used to speak on the intercom.
Push the knob again and the systems toggles back to
voice activation. The mode is shown by the green indica-
tion in the text.
Intercom Volume Control
The intercom volume control knob adjusts the loudness
of the intercom for the intercom stations(s) connected to
the audio controller panel. It has no effect on selected
radio levels, or music input levels.
In 2-control panel installation, the pilot panel controls pilot intercom vol-
ume only, copilot panel controls copilot and passenger intercom volume.
Monaural headsets
The pilot and copilot positions work with stereo or mono headsets. Howev-
er, Multi-Talker will not be presented correctly unless stereo headsets are
used, and oriented correctly on the head, left and right.
NOTE: For the full effect of Multi-Talker® Dimensional Sound, stereo
headsets must be used, and the left/right orientation observed.
All passenger headsets are connected in parallel. Therefore, if a monaural
headset is plugged in to a PAC45 Stereo installation, one channel will be
shorted. Although no damage to the unit will occur, all passengers with
stereo headsets will not hear one channel, unless they switch to the
“MONO” mode on their headset.
