This adaptor has been designed to overcome the problems of incompatibility between aviation headsets of different makes and models when used in the same aircraft. The HMU-1 is supplied ready to use with a PP3 9V battery, simply plug a headset into the matching unit, and the HMU-1 into the aircraft, and the unit will work automatically.
This 'Triple Headset Adaptor' will convert one set of radio or intercom and headphone sockets (normally mounted on the panel of the aircraft) to be used by up to three headsets fitted with standard microphone and headphone plugs.
So, it is ideal if the pilot or co-pilot wishes to communicate with up to two passengers in the back of the aircraft. It will also enable them to listen to communications between the pilot and co-pilot and those of air traffic control.
The 'Triple Headset Adaptor' therefore comprises two male plugs and six female sockets.
The cabling is long enough (approx 5') to extend to the rear cockpit passengers in a conventional sized aircraft cockpit.
