Selection Description
INTERCOM
(ENABLED/
DISABLED)
Turns the intercom function on or off. When intercom is disabled, music and
auxiliary inputs are also disabled. Intercom Disabled is the suggested setting
when the GTR is being wired to an audio panel. This setting may also affect
Sidetone functionality, see
Section 3-4 .
Using a headset that has a MIC Telephone switch option may disable the intercom
function. To restore intercom function, turn the MIC Telephone switch to the Off
position, and power cycle the GTR200.
RECEIVER OUT
GAIN
When the intercom is enabled, RECEIVER AUDIO OUT (pin 10) will output
everything the pilot hears in the headset ear speakers with the exception of music
audio. If RECEIVER AUDIO OUT is used as the source of audio to a recording
device then adjust the RCVR OUT GAIN setting for desired audio level at the
recording device.
AUX SQ 1 & 2
AUX SQ prevents low level noise from being passed to the headset ear speakers.
Adjust the AUX SQ level so the audio background noise is muted. Warning,
adjusting the AUX SQ to a high level may squelch the desired audio.
AUX VOL 1 & 2
If AUX1 or AUX2 inputs are used these settings allow adjusting the sensitivity of
the AUX inputs.
AUX MUTE
(MUSIC) 1 & 2 This setting when enabled, will mute the music input if AUX1 or AUX2 input levels
are sufficient to break AUX SQ.
PILOT ON RIGHT
SIDE Select YES or NO to select pilot location. When YES is selected the copilot is
positioned to the left of the pilot for 3D audio processing.
