We have a customer with an Agusta119 Helicopter.
He has a set of 5 A20 headsets (non-bluetooth) supplied with the aircraft which have the Agusta 8 pin plug. I believe the mic setup is low impedance.
We have been given some replacement mic/cable assemblies with bluetooth to be fitted to these headsets. When the cable assembly is fitted to a headset, the mic no longer works with the aircraft system, but still works fine with phone calls via the bluetooth interface.
Part number of the cable is 327070-3050.
The headsets in question I am led to believe are series 1 A20.
Can someone advise us on whether this cable assembly is compatible with this system, and if not, is there a cable assembly that will work?
