Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the AA83-001
InterMUSIC™ stereo intercom.
3.2 General
The AA83-001 InterMUSIC™ is a stereo intercom system that supports a pilot, copilot and two
passengers. It provides entertainment and communication audio in full stereo to all four headsets, and
transceiver control for both the pilot and copilot. The InterMUSIC™ family of stereo intercoms allows
several installation configurations from single unit systems, to fully independent stations for the pilot,
copilot and passengers. Tie Line connections are compatible with other AEM systems including AA82,
AMS40 and AA95 series units for expanded systems.
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 AA83-001 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 front panel annunciator allows easy visual setting of
the VOX threshold, and also indicates transmit operation.
3.2.2 Communication
Functions
The AA83-001 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 AEM intercom systems. The
AA83-001 can support PTT ICS operation for all users, and can be wired to cyclic/yoke switches for both
TX and ICS functions.
The balance adjustment pots permit signals to be shifted in the user's acoustic listening space so that
tower transmissions appear to come from one area, and intercom from another. This greatly aids in
signal recognition and more accurately reproduces a natural listening environment for the flight crew.
