Does anyone know what pin 6 of J401A of the Narco Com 11B is?
My pin out drawing shows "N/C". However, the aircraft installation I am
working with has a wire at that location which I cannot figure out where
it goes.
I am removing the 11B and replacing it with a different unit.

Thanks is advance

On the COM11A pin 6 of J401A is called PHONES & SPEAKER GND.

It is internally connected to the case of the unit. It looks like a possible way to limit ground noise in audio systems caused by audio frequency currents in the airframe. Check to see if the speaker or the phone jacks are insulated from airframe ground and wired to return current to pin 6.

And. . . A COMM 11 B might be different.
