PMA8000G Pilot Guide R3
This is normal. The
IntelliV ox
® 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 area, such as in the
hangar, or without the engine running. This is also nor-
mal.
Intercom Volume Control (7)
The small volume control knob adjusts the loudness of
the intercom for the pilot and copilot. It has no effect
on selected radio levels, music input levels or passen-
gers' volume level.
The larger, outer volume control knob controls intercom volume for the pas-
sengers. It has no effect on radio or music levels.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with mono headsets. However, the In-
telliAudio® feature will not function.
If a monaural headset is plugged in to a PMA8000G Stereo installation, one
channel will be shorted and all passengers will lose one channel unless they
switch to the “MONO” mode on the headset.
Intercom Modes (8)
The intercom has three modes. This button cycles through the intercom
modes, from top to bottom and then back up. The description of the intercom
mode function is valid only when the unit is not in the "
Split
" mode.
I
:
The pilot is isolated from the intercom and is connected only to the air-
craft radio system. He will hear the aircraft radio reception (and sidetone
during radio transmissions). Copilot will hear
passengers’ intercom and entertainment, while
passengers will hear copilot intercom and enter-
tainment. Neither will hear aircraft radio recep-
tions or pilot transmissions. The pilot can hear
music if desired by pressing the MUSIC button.
A
:
All parties will hear the aircraft radio and
intercom. Crew and passengers will hear select-
ed entertainment. During any radio or intercom communications, the music
volume automatically decreases. The music volume increases gradually back
to the original level after communications have been completed.
C
: Pilot and copilot are connected on one intercom channel and have
exclusive access to the aircraft radios. They may also listen to Entertainment
1. Passengers can continue to communicate with themselves without inter-
rupting the Crew and may listen to entertainment as configured.
In
SPLIT
mode, the intercom, and the indicator are off for the crew. Pressing
the
Mute
