AA12S Series Compact Audio Controller Manual

SM69 Rev. 4.00

3.3.2.2ICS Volume Control

The ICS VOL control, which has a line to mark rotational position, is at minimum volume when fully ccw. As the knob is rotated cw, the ICS volume for crew and PAX increases.

The ICS is muted during transmit operations.

3.3.3PILOT ISO / NORM Modes

Pilot Isolate Switch

The PILOT ISO/NORM control is a red, two-position toggle switch that allows selection of either NORM (Normal) or PILOT ISO (Pilot Isolate).

In NORM mode (default) everyone on the system can talk to each other, listen to music, and hear all selected radio audio.

The PILOT ISO mode separates the pilot from the intercom network, allowing confidential radio communications without interference from the copilot or passenger intercom or music, while maintaining complete control of all the radio functions of the audio panel. The copilot and passengers retain normal intercom and music functions.

Note: In PILOT ISO mode, the receive/sidetone levels may require adjustment at the audio source.

3.3.4Entertainment 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.
