Page 6-11

6.4.4 Audio Configuration

6.4.4.1 COM Sidetone

The COM Sidetone page (Figure 6-18) allows the installer to adjust the COM sidetone volume. COM 
sidetone is the audio spoken into the COM microphone. This setting only affects the volume of the 
sidetone for the GTR/GNC COM during PTT. To adjust the COM sidetone volume, rotate the smaller 
inner knob to the desired value. This field is adjustable in the range of 0 (zero) to 100. The default is 50. 

Figure 6-18. COM Sidetone Page

6.4.4.2 Mix NAV Audio

The Mix NAV Audio page (Figure 6-19) allows the installer to configure whether NAV audio is mixed 
with the COM headphones. With this option set to ‘On’, the NAV audio will be sent along with COM 
audio to the pilot’s headphones and the audio will be ‘mixed’. With this option set to ‘Off’, the NAV audio 
will not be heard in the pilot’s headphones. The NAV audio will still be sent over the analog audio lines on 
P2002-16 and 17. In installations with an audio panel, this should be set to ‘Off’. Use the smaller inner 
knob to select On or Off. Press 

ENT

 when the appropriate selection is displayed. 

Figure 6-19. Mix NAV Audio Page

6.4.4.3 Hi-Fidelity Audio

The Hi-Fidelity Audio page (Figure 6-20) allows the installer to enable or disable the hi-fidelity Aux audio 
input on the GTR/GNC. If a music audio source is connected to P2001-3 and 19, it may be desirable to 
enable the Hi-Fidelity audio. Use the smaller inner knob to select On or Off. Press 

ENT

 when the 

appropriate selection is displayed.
