Compatibility BOSE A20 with C-130J
I have bought the Bose A20 headset with U174 pin (NO Bluetooth), which perfectly fit in the C-130J audio receptacle.
The headset seems to work fine, but when connected to the plane with the "noise reduction" ON every transmission becomes a feast of shrieking noises.
This happens either in VOX or transmitting on any radio. I have changed cables (audio cables in the plane) and position in the cockpit.
Funnily enough this happens both in Pilot and Copilot seat but not in the Third member seat!!! (on the third member the Headset works fine!)
I am wondering if the headset may possibly have impedance issues.. do you have any inputs???
Ps I have used the headset without the noise cancelling and the mic itself works!
Thank you very much in advance!
