3.6.2 Push to talk intercom (PTT ICS)
Pressing the intercom volume knob (ICS VOL) will place the system (all headsets) 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 (all headsets) toggles back to voice activa-
tion. The mode is shown by the green indication in the text.
3.6.3 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 a single control panel installation the volume control adjusts pilot, copilot, and
any passengers.
In 2-control (pilot & copilot) panel installation, the pilot panel controls pilot intercom volume
only, copilot panel controls copilot and passenger intercom volume. In a 2-panel installation
with one crew panel and one mission panel, the crew volume control controls the intercom vol-
ume for pilot and copilot, and the mission/observer panel controls passenger intercom volume.
In a 3-control panel installation, the pilot, copilot, and mission panel volume control adjusts the
intercom associated with that control head.
3.6.3.1 Monaural headsets
The pilot and copilot positions work with stereo or mono headsets. However, MultiTalker 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 MultiTalker Dimensional Sound, stereo headsets must be used,
and the left/right orientation observed.
Some passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged
in to a PAC45 Stereo installation, one channel may 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.
NOTE: Mono headsets that short the tip and ring (i.e. older models) will introduce some au-
dio distortion when used. Modern, stereo headsets are recommended in all positions.
