I have a PS Engineering PS-501 intercomm attached to a KING KA-134 Audio panel. I was working behind my panel (already flying aircraft) and I must have bumped a wire or something under the instrument panel.
When I key my radios (either of them) they transmit, but my mike audio doesn't transmit. I have tried to plug into the Co-Pilot jacks and I have the same symptom. The intercomm works perfectly. (I have an ICOM A200 and a TKM MX-11. they are connected as COM1 and COM2). This all worked before but I must have messed something up behind the panel.
Please see the attached technical data. Does Anyone have any ideas?

I cant figure out what pin takes the transmit microphone audio from the jacks to the audio panel. Does it go thru the PS-501? HELP!!
