AA12 Compact Audio Controller Manual SM21 Rev. 4.10

2.3.7 Adjustments

The unit is shipped from the factory with all internal adjustments set to the normal test

levels. Once installed in the aircraft, it may be desirable to change some of these

settings to best suit the local operating environment. The internal adjustments that can

be varied are located along the left side of the unit and are as follows:

ATC Adjusts the trigger point for music muting from an incoming radio source. Fully

CCW will disable the music input. Fully CW will disable the ATC MUTE capability for

the music.

S/T Adjusts level of internally generated artificial sidetone. Should be used only if

sidetone is not produced by existing radios. Normally set to OFF (fully CCW).

RX Adjusts level of receive audio from radio equipment. Should be balanced for

adequate level in both InterVOX and PIL ISO modes of operation, when monitored from

the pilot position.

MUSIC Adjusts level of external music source (Walkman, etc.). Typically set to

mid range.

Upon satisfactory completion of all performance checks, make the required log

entries and complete the necessary Regulatory Agency paperwork before

releasing the aircraft for service.
