Section 1.0 Description
1.1 Introduction
This manual contains information on the AA95-766 Single Channel Audio Controller. Information in this
section consists of purpose of equipment, features and specifications.
1.2
Purpose of Equipment
The AA95-766 is a Dzus mounted audio panel with built in intercom and lighted faceplate. The unit provides
full headset transmit (TX), receive (RX) and intercom (ICS) functions for the pilot and co-pilot users. Only
intercom and receiver audio are provided for passengers. The front panel controls permit user adjustment of
frequently needed signals.
The users have control of five transceiver positions, six receiver inputs, and one PA output. The unswitched
inputs are direct audio and tape player.
The AA95-766 supports only one lo-z mic input and five hi-z mic inputs per box. All phone outputs are hi-z.
Connection to other stations in the system is made through the ICS Tie line. The AA95-766 is plug compatible
with most AA95 and AMS40 series AEM audio panels.
The small size and extensive radio and ICS functions make this unit an excellent choice for multi-station
aircraft.
1.3
Features
Transceiver interfacing for the AA95-766 is accomplished through directly switched microphones. To
ensure maximum radio compatibility, it has a ground
–
referenced keyline that incorporates no diodes or
other steering components.
Independent control is provided for each audio channel within the controller, allowing sidetone, ICS audio,
and RX audio to be independently set.
The ICS tie line is fully compatible with other AEM systems including the AA80, AA82, AMS4X and AA9X
series units.
Boom mic support is provided for the pilot and co-pilot, with both ICS and TX functions via cyclic or yoke
switching. The AA95-766 has a built-in dynamic microphone amplifier for an M87- type mic. The Live
(Hot Mic) and VOX ICS functionality allow immediate transmission via these modes without further control
panel switching, and immediate return to ICS operation on completion. The ICS function is achieved
using dynamic noise reduction and active filtering. This provides the clearest possible ICS audio under
high ambient noise conditions by rejecting airframe and wind noise, and passing only voice band
information.
