Section 1.0 Description
1.1 Introduction
Information in this section consists of product description, design features and specifications for the
AA12S Series Compact Audio Controller. All derivative product information shall be contained in the
applicable manual supplement, which may be obtained from AEM as required.
Review all notes, warnings and cautions.
1.2 Purpose of Equipment
The AA12S is a compact Dzus-mounted audio controller with an integral 4-place stereo voice-activated
intercom. It provides intercom capabilities for the pilot, co-pilot and two passengers (PAX). The AA12S
accepts stereo music inputs from either portable or fixed entertainment systems to produce high quality stereo
headset output.
Radio functions include selectable transmit capability for pilot and co-pilot on 3 COM radios and a PA.
Receive audio selections include COM1, COM2, COM3, MKR, NAV, ADF, and DME.
1.3 Design Features
All four mics have individual VOX gating. Each gate may also be activated with the corresponding ICS
keyline.
ICS muting is automatic during radio transmission.
The unit is supplied to suit a standard AEM bi-directional ICS audio TIE line for multi-unit interface
(configuration dependent). The crew and PAX are always connected except in the case of Pilot ISO
mode, when the pilot is disconnected from the ICS tie line.
If required, one or more receiver audio inputs may be configured at the factory prior to ordering as an
unswitched Direct Audio input. A new part number may be assigned. Contact AEM Product Support for
further information.
The following audio levels can be adjusted at the time of installation, or during service by an approved
dealer, using individual level trimpots.
