Gomer Pylot Posted July 10, 2011 Report Share Posted July 10, 2011 Maybe nothing. It depends on the Robinson. Military helicopters use low-impedance avionics, ~8 ohms. Most civilian avionics are high-impedance, ~300 ohms. You would need a new microphone for sure, and the speakers may need to be changed. You may be able to use the existing speakers, although the volume will be lower than usual. I've seen that go both ways. I kept the low-impedance speakers in my helmet, because the volume was unbearably high with high-impedance speakers. But the mike has to be changed if you use the headset in a high-impedance ship, or you can't talk. Quote Link to comment Share on other sites More sharing options...
r22butters Posted July 10, 2011 Report Share Posted July 10, 2011 For future reference... The DC H10-66 has a switch to go from high to low, and may be a better option for military to civilian applications? Quote Link to comment Share on other sites More sharing options...
dowd Posted July 10, 2011 Report Share Posted July 10, 2011 Buy David Clark impedance adapter 40880g-01 $133.25 . But it has Two plug out put for air plane radios so you'll need david clark 1825g-06 "Y" $88.26 . But for that much money you can get a new headset. Or get equivalet adapters from other manufacturers for less money (Y adapter around $40)or used off Ebay. Maybe you can special order helicopter male impedance adapter from David Clark. Or solder a helicopter plug on impedance adapter. Quote Link to comment Share on other sites More sharing options...
Gomer Pylot Posted July 10, 2011 Report Share Posted July 10, 2011 Forget the adapters, you can get a microphone for less money. The only way an adapter makes sense is if it's significantly cheaper than a microphone, and you can get one of those online for not a lot of money.

mausermolt Posted July 12, 2011 Author Report Share Posted July 12, 2011 so i found this thingy http://www.skygeek.com/pa-88h.html it says it converts the impedance from low to high by itself. think that would work instead of a mic? or would i need a mic also?

I wouldn't pay twice the price for a converter, but it's your money. Quote Link to comment Share on other sites More sharing options...
