The indicator LED will show the selected transmitter.
  • Page 36 PS Engineering PAC45 Audio Selector Panel and Intercom System Installation and Operator’s Manual You will always hear the audio from the selected transceiver, even if the selected com audio is turned all the way down on the audio controller because it cannot turn the selected receive au- dio all the way off.
  • Page 37 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 installation of a Micro- phone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX perfor- mance, but will improve the overall clarity of all your communications.
