The Headset adapter (twin jack) allows Micro System headsets to connect to the intercom systems installed in light aircraft. The adapter converts the modern multi pole connector used in Micro system headsets to fit standard aviation twin jack plug sockets. The adapter also includes electronics which provide the correct microphone and speaker levels to the twin jack intercom system. This makes the adapter plug and play compatible with all modern aircraft intercom systems. The adapter is designed to be immune to electromagnetic interference and to prevent radio frequency (RF) feedback, which are often associated with external connections to Airband radio equipment.
