Section 1 Description
1.1 Introduction
Information in this section consists of product description, design features and specifications for the
AA12S-600 Compact Stereo Audio Controller. All derivative product information shall be contained in the
applicable manual supplement, which may be obtained from Northern Airborne Technology Ltd. as
required.
Review all notes, warnings and cautions.
1.2 Product Description
The AA12S-600 is a compact Dzus-mounted audio controller with an integral 6 - place stereo voice
activated intercom. It provides intercom capabilities for two crew members (CREW 1 and CREW 2) and
four passengers (PAX 1 – PAX 4). Stereo music inputs are provided to connect either portable or fixed
entertainment systems to produce stereo headset output. Connectivity is provided for four COM
transceivers, nine COM/NAV receivers and four Direct Audio inputs. The fourth COM position can be
used to service a PA or additional AUX receiver.
1.3 Design Features
All microphones have individual VOX gating. Each VOX gate is activated by the corresponding ICS
keyline or when the microphone level exceeds the VOX threshold level. The VOX threshold level can be
set anywhere between live (HOT) and keyed (KEY).
The unit is supplied to suit a standard NAT bi-directional ICS audio TIE line for multi-unit interface
(configuration dependent). The ICS audio is muted to the applicable ICS group when an applicable user's
TX keyline is activated.
A stereo music input accepts audio signals from portable entertainment units, CD players or other
integrated on-board systems through the airframe connector J101. Stereo output delivers music to stereo,
or standard monaural, general aviation headsets (installation specific). Music muting occurs during radio
transmit or receive or intercom activity. The music mute level is adjustable for muting that occurs during
receive or intercom activity. The music is fully muted (disabled) during radio transmit.
The following audio levels can be adjusted at the time of installation, or during service by an approved
dealer, using individual level trimpots.
- Artificial Side Tone (AST ADJ) - Music Right Bass (MUSIC RIGHT BASS)
- Crew ICS Balance (CREW ICS BAL) - Music Right Treble (MUSIC RIGHT TREB)
- Direct Volume (DIR VOL) - PAX ICS Balance (PAX ICS BAL)
- Music Balance (MUSIC BAL) - Receive Balance (RX BAL)
- Music Left Bass (MUSIC LEFT BASS) - Receive Volume (RX VOL)
- Music Left Treble (MUSIC LEFT TREB) - Receive VOX (RX VOX)
- Music Mute Level (MUS MUTE LVL)
