The AA38 Series Aircraft Intercom System Local ICS Loop provides intercom functions with operation in Live, VOX, or PTT modes. The units are bulkhead mounted containing all the circuitry required to support a wide variety of ICS Loop applications, particularly isolation/ICS amplifier use, where the output is required to be headset or line level. A switch-selectable NAT/Andrea allows connections to larger audio systems, and an auxiliary input allows for audio input from an audio panel or transceiver.
Version AA38-501has functions for 4 users with low impedance headsets.
