Entertainment Audio
The AA12S accepts stereo music input from portable entertainment units, CD players or other integrated
on-board systems. The stereo output delivers music to stereo, or standard monaural, general aviation
headsets (installation dependent).
Music muting occurs during any radio or intercom activity.
3.3.5
Automatic Fail-safe
In the event of a power failure, automatic fail-
safe operation will be activated. This routes the pilot’s
phones, mic audio, and mic PTT directly to the COM radio selected by the position of the TX rotary
selector switch, and selected audio inputs. Copilot and passengers will have no ICS, music, or receive
functions.
In the unlikely event of an AA12S circuit failure that results in a communication failure, the automatic fail-
safe mode can be enabled by pulling the AA12S circuit breaker.
Notes:
1) In Automatic Fail-Safe mode, the receive/sidetone levels may require adjustment at the audio
source.
2) The pilot should confirm that all aspects of Automatic Fail-Safe operation are working before
accepting the aircraft into service.
