Abstract: A jack (90) typically mounted in an aircraft seat is adapted for use with a variety of headset types. A jack has sockets (92, 93, 94) accepting any of several different types of plugs associated with different types of noise cancellation headsets or aviation industry headsets including one, two, or three pin types. The jack includes sensing components to correctly detect from the number of pins inserted, and the impedance and/or voltages sensed on those pins, the type of headset being used.
Abstract: A jack typically for aircraft headphones has sockets (802) accepting any of several different types of headsets (804), and attached sensing components (801) to correctly detect from the number of pins inserted and the impedances and/or voltages sensed on those pins the type of headset inserted. Connection is then appropriately made to the audio while the stereo or noise cancellation properties of the headsets are correctly used.
