Purpose of Equipment
The AA82 InterMusic
Stereo Intercom System is a system for passenger entertainment and
communications. The system is available in two models, the AA82-001 and AA82-060. The AA82-001 is
compatible with AA80 intercoms and allows four stereo positions. The AA82-060 is compatible with AA83
intercoms and allows six stereo positions. Each is linked via the ICS Tie Line to the crew audio system.
The AA82 InterMUSIC
Stereo Intercom offers the passengers full control of their intercom and entertainment
functions. The front panel controls permit adjustment of Intercom level, VOX threshold and Music level.
Internal adjustments set Receive level, Receive Balance, ICS balance, ICS bass, Music muting and Music
balance. These controls allow unique features such as making the intercom audio appear to be coming from
the left and receive audio coming from the right, which is helpful in relating the audio to the source. The stereo
audio is muted during intercom operation or when receive audio is detected, permitting greater intelligibility of
in-coming transmissions. A front panel annunciator allows easy visual setting of the VOX threshold and also
indicates RX signal reception.
The AA82 uses surface mount technology and provides true stereo music audio to the headset.
The Inter MUSIC
™ system employs NAT’s unique audio processing, which reduces noise and tail
frequency response to produce clean, crisp intercom audio.
High output power and low distortion results in better on-board communication and greatly reduces noise
Employing highly integrated stereo audio processors, component numbers were substantially reduced
and product reliability is increased.
With the reduction of component size, more features were incorporated (Adjustable music muting by
intercom and receive audio, bass control of intercom and stereo audio).
Designed into the smallest possible chassis, it allows mounting in the remotest locations usually close to
