CONFIDENTIAL AND PROPRIETARY TO ANODYNE ELECTRONICS MANUFACTURING CORP.

All audio installations can be seriously degraded by incorrect wiring and shielding, and may result in

abnormal cross-talk, hum and ground-loop noise. Be especially careful with all microphone wiring and

Tie Line wiring, as these lines carry the lowest level signals in the aircraft.

All microphone and headset jacks should be electrically isolated from the airframe or significant ground

loop noise may result.

2.3.3 Cabling and Wiring

All unshielded wire shall be selected in accordance with AC43.13-1B Change 1, Paragraphs 11-76

through 11-78. Wire types should be to MIL-W-22759 as specified in AC43.13-1B Change 1,

Paragraphs 11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel MIL-C-

27500 shielded wire with solder sleeves (for shield terminations) to make the most compact and easily

terminated interconnect. Follow the wiring diagrams in Section 2.6 as required.

Allow 3 inches from the end of the wire to the shield termination to allow the hood to be easily installed.

Note that the hood is a ‘clamshell’ hood, and is installed after the wiring is comp lete. Aircraft

harnessing should permit the unit to be lowered from the panel for easy access to all side adjustments.

Do NOT mount the unit until all adjustments have been carried out.

All wiring should be at least 22 AWG. Ensure that all ground connections are clean and well secured,

and that they share no path with any electrically noisy aircraft accessories such as blowers, turn and bank

instruments or similar loads. Power to this unit must be supplied from a separate breaker (1 A) or fuse (1

A fast), and not attached to any other existing breaker without additional protection. The correct fuse is

included with the AA83.

Ensure that all ground connections are clean and well secured.

2.3.4 Adjustments

The unit ships 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.

CAUTION

Before performing the following adjustments ensure the aircraft radio’s volume control

is set to produce 2.5 Vrms r10 % at the input to the AA83-001, or the mute functions

may not operate correctly.

The internal adjustments are located along the sides of the unit and are as follows:

2.3.4.1 ICS, RX, and MUSIC BAL.

These potentiometers are used to adjust the headset stereo balance.
