2.3.3
Cabling and Wiring
All unshielded wire should be to MIL-W-22759 or equivalent. 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 complete. 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, except power and ground lines, which should be at least 20 AWG.
Ensure that the ground connection is clean and well secured, and that it shares 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 (1/2 A) or fuse (1/2 A fast), and not attached to any
other existing breaker without additional protection. The correct fuse is included with the AA83-001.
2.3.4 Installation
Notes
All AA95/AMS4X Audio Controllers used with the AA83-001 must have the ICS Tie Line and Gain
Modifications installed. This will only be a concern on Audio Controllers with S/N 1918 or before. If the
AA83-001 is used with a second unit such as an AA82, you may wish to install the 2.2 k
: resistor shown
in the installation drawing. This is used to equalize ICS Tie Line loading when changing from the tie to
split connections.
If you are not familiar with Tie Line techniques, request the installation bulletin from AEM covering Tie
Line theory and practice.
2.3.5 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.
