Question

Can you put a helicopter headset plug into a Ultracom intercom?

Answer 1

Standard GA headsets use two plugs, one for the Mic (has two contacts) and one for the earphones (has three contacts). The heli uses a single plug for both (has four contacts).

It will work if you have the proper jacks in the aircraft that match the helicopter plugs, otherwise you'll have to get an adapter. David Clark sells these adapters.
