I've already posted this on the Dynon Avionics Site. Someone here, may know what I've done or failed to do to .
I am in the process of installing and wiring the Intercom-2S. Headphones appear to be working OK (I can hear the Dynon welcome message), but I can't hear myself in the intercom when I talk through my Bose-A20 headsets, both on the pilot side and the co-pilot side. I have two headsets, same on both. What could be the problem? I'm aware that there could be a multitude of possibilities.
Things I am aware of, and have checked are as follows:
Wired MIC to smaller diameter Jack.
Checked all the wire runs go to correct -2S pins.
HP jack ground wires connect to each other then to -2S, Pin-1.
MIC grounds go to -2S Pin-2.
Shields connected together, daisy chain, and then to -2S, Pin-1.
I am aware of the 'Tip, Ring Barrel, architecture concept.
My wires are connected as follows:
Pilot HP: Tip to Pin-9, Ring to Pin-22, Barrel to Pin-1
Co-pilot HP: Tip to Pin-8, Ring to Pin-21, Barrel to Pin-1
Pilot MIC: Tip to Pin-23, Ring to Pin-10, Barrel to Pin-2
Co-pilot MIC: Tip to Pin-3, Ring to Pin-16, Barrel to Pin-2
I haven't connected up the PTT wiring yet. I also need to check the continuity of each wire again. Am I missing something obvious?
