4.5.9 Headset Outputs

NOTE

Copilot and Passenger headset outputs are internally the same connection. Separate

Passenger headset output pins are provided for wiring convenience and GMA 340 pin

compatibility.

NOTE

For CREW ISO configuration, the copilot's headphone jack should be wired in parallel

with the pilot jack to the Pilot headset output pins. Passengers may be connected to either

the copilot or passenger pins.

NOTE

Using a mono headset with an audio jack wired for stereo may damage the GMA 240.

Installations using only mono headsets may use a stereo audio jack and leave the ring

contact unconnected or install a switch as shown in Figure 4-4. Also note that many

stereo headsets have a mono/stereo switch to be compatible with mono or stereo-wired

jacks.
