PMA8000G IntelliAudio Audio Selector Panel With flightmate®
Installation and Operator’s Manual
200-890-0912 Page 3-5 Rev. 7, July 2017
For optimum microphone performance, PS Engineering recommends installation of a Microphone Muff Kit
from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will improve the
overall clarity of all your communications.

3.6.2 Intercom Volume Control (7)
The inner volume control knob adjusts the loudness of the intercom for the pilot and copilot. It has no ef-
fect on selected radio levels, music input levels or passengers' volume level.
The outer volume control knob controls intercom volume for the passengers. It has no effect on radio or
music levels.
Adjust the radios and intercom volume for a comfortable listening level. Most general aviation headsets
today have built-in volume controls; therefore, volume also can be further adjusted at the individual head-
set.
3.6.2.1 Mono headsets in Stereo Installation
The pilot and copilot positions will function with mono headsets. However, the IntelliAudio functionality
will be lost.
All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a
PMA8000G 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. Passengers will not receive IntelliAudio functionality.
3.6.3 Intercom Modes (8)
The “ICS” pushbutton switch on the left side of the panel provides the selection of the three intercom
modes. The description of the intercom mode function is valid only when the unit is not in the "Split"
mode. Then, the pilot and copilot intercom is controlled with the Mute button.
This button cycles through the intercom modes, from top to bottom, then bottom to top as: ISO, ALL Crew
and Crew, ALL, ISO. An LED shows which mode is currently active.
ISO: The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear
the aircraft radio reception (and sidetone during radio transmissions). Copilot will hear passengers’ inter-
com and entertainment, while passengers will hear copilot intercom and entertainment. Neither will hear
aircraft radio receptions or pilot transmissions. The pilot can hear music if desired by pressing the MUSIC
button.
ALL: All parties will hear the aircraft radio and intercom. Crew and passengers will hear selected enter-
tainment. 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.
