™
Stereo Intercom Manual
Section 3 Operation
3.1 Introduction
Information in this manual consists of the functional and operational procedures for the
AA83-100 InterMUSIC
™
Stereo Intercom.
3.2 General Operation
The AA83-100 is a 4-place stereo voice-activated intercom that provides full intercom
capabilities for the pilot and copilot and two passengers (PAX). It provides
entertainment and communication audio in full stereo to all four headsets, and
transceiver control for both the pilot and co-pilot. The AA83-100 accepts stereo music
input from portable entertainment units, CD players or other integrated on-board
systems to produce high quality stereo headset output. The InterMUSIC
™
family of
stereo intercoms allows several installation configurations - from single unit systems, to
fully independent stations for the pilot, copilot and passengers. For expanded systems,
tie line connections are compatible with other NAT systems including AA82, AMS40 and
AA95 series units.
3.2.1 Stereo & Intercom Special Features
The stereo music audio is muted during transmit or intercom operation and when radio
receive audio is detected, permitting greater intelligibility of incoming transmissions.
The AA83-100 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 front panel annunciator allows easy visual
setting of the VOX threshold, and also indicates transmit operation.
3.2.2 Communication Functions
The AA83-100 provides full boom-mic transmit and ICS functions for the pilot and co-
pilot, and provides ICS and radio monitor operation for two additional passengers. Pilot
priority on transmit and pilot isolation (direct connection to the aircraft radio system) are
standard features on all NAT intercom systems. The AA83-100 can support PTT ICS
operation for all users, and can be wired to cyclic/yoke switches for both TX and ICS
functions.
3.2.3 Important Operating Considerations
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 out one side of the AA83-100 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, and
be sure the aircraft is placarded appropriately.
