GENERAL
The AA83-001 is a stereo voice-activated intercom, providing full intercom capabilities for pilot and
copilot. Further passenger features are not used in the configuration installed. The AA83-001 also
provides transmit capability for pilot and co-pilot to a single COM radio or audio selector panel. The
AA83-001 accepts stereo music inputs from either portable or fixed entertainment systems to
produce high quality stereo headset output.
The stereo music audio is muted during transmit or intercom operation and when receive audio is
detected, permitting greater intelligibility of incoming transmissions. The AA83-001 muting depth
adjustment ranges from complete music muting to gentle background music on command, with
a fast attack and slow level return for optimum user comfort.
Each microphone is individually gated, for the best possible noise performance during VOX
operation. A panel annunciator allows easy visual setting of the VOX threshold, and also indicates
transmit operation. The AA83-001 provides full boom-mic transmit and ICS functions for the pilot
and copilot. Pilot priority on transmit and pilot isolation/fail-safe (direct connection to the aircraft
radio system) are standard features.
CAUTION
Ensure headsets are of good quality and are installed correctly. NEVER USE MONO
AIRCRAFT HEADSETS in this system unless the installation has been specifically
wired for mono operation, as they will short cut one side of the AA83-001 power
amplifier when installed in stereo jacks. This may result in eventual unit failure, which
IS NOT COVERED BY WARRANTY. Use only stereo headsets with this system.
