I have a weird problem that I have never seen before with brand new 403MC installation. I wired up the radio and intercom exactly like their installation sheet shows. 4 place intercom. I used my Zulu ANR headsets for the setup. Everything appeared to work great. Intercom, side tone, tx/rx etc.
However, if I use a standard David Clark or Sigtronics headset I get nothing. No intercom or side tone. But if I plug in a single Zulu into any of the positions, it all starts working fine again.
Any ideas why my Zulu's would work fine and but not a dumb headset?
I called Flightcom this morning and the guy was stumped. He is supposed to run it past his team and get back to me.
