Section 1.0 Description
1.1 Introduction
This manual contains general information on the AA30-0xx Expansion Switches. There are many
different variants of the AA30-0xx available; in this manual the AA30-013 is described as an example of a
single user unit, and the AA30-014 as an example of a dual user unit. Derivative products may be
covered by manual supplements, which can be obtained from AEM if available. Information in this
section consists of purpose of equipment, features and specifications.
1.2 Purpose of Equipment
The AA30-013 is a single-position expansion switch, and the AA30-014 is a dual-position expansion switch.
Both provide transmit capability.
1.3 Features
The AA30-013 is a compact Dzus mounted switch expansion unit that provides expansion for one user
and contains only one board. The AA30-014 is a compact Dzus mounted switch expansion unit that
provides independent expansion for two users, using two identical circuit boards.
The transmit function allows each user to select one of three transceivers (or two transceivers and
intercom). Receive audio can be selected regardless of the transmit selector switch position.

Section 2.0 Installation
2.1 Introduction
Information in this section consists of: unpacking and inspection procedures, installation procedures,
post-installation checks, and installation drawings.
2.2 Unpacking and Inspection
Unpack the equipment carefully. Inspect the unit visually for damage due to shipping and report all such
claims immediately to the carrier involved. Note that each unit should have the following:
- AA30-0xx Expansion Switch
- Product Information Card
- Release certification
Verify that all items are present before proceeding and report any shortage immediately to your supplier.
2.2.1 Warranty
All Anodyne Electronics Manufacturing Corp. (AEM) products are warranted for 2 years. See the website
www.aem-corp.com/warranty for complete details.
2.3 Installation Procedures
2.3.1 Warnings
Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any audio or DC power
lines from this unit with 400 Hz synchro wiring or AC power lines. Do not position this unit or wiring from
this unit next to any device with a strong alternating magnetic field such as an inverter, or significant audio
interference will result.
2.3.2 Cautions
In all installations, use shielded cable exactly as shown and ground as indicated. Significant ground loop
and noise problems may result from not following these guidelines.
The shielding and routing of the MIC LINES used in the AA30-0xx installation is very critical and poor
performance of the aircraft audio system will result if these issues are not handled properly.

ENG-FORM: 805-0100.DOTX
CONFIDENTIAL AND PROPRIETARY TO ANODYNE ELECTRONICS MANUFACTURING CORP.
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 complete.
All wiring should be at least 22 AWG, except power and ground lines, which should be at least 20 AWG.
Ensure that all ground connections are clean and well secured.
2.3.4 Post-Installation Checks
2.3.4.1 AA30-013 Voltage/Resistance Checks
Check the following:
a) P101 pin <9> for +28 Vdc lighting buss voltage.
b) P101 pin <22> and <24> for continuity to ground.
2.3.4.2 AA30-014 Voltage/Resistance Checks
Check the following:
a) P101 and P102 pins <7> for +28 Vdc avionics buss voltage.
b) P101 and P102 pins <9> for +28 Vdc lighting buss voltage (only one required).
c) P101 and P102 pins <22> and <24> for continuity to ground.
d) P101 and P102 pins <11> for continuity to ground when keyed.
2.3.4.3 Power On Checks
WARNING:
High volume settings can cause hearing damage.
Set the headset volume control to the minimum volume setting prior to
conducting these tests and slowly increase the headset volume level to
a comfortable listening level.
a) Install the AA30-0xx and power up the ship’s systems. Turn on the radios and accessories
required for the system.
b) Check for correct radio audio and adjust for acceptable level.
c) Run through all installed functions, and check the RX and TX functions for all users. Refer to
Section 3 for operation details.

2.3.5 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.
2.3.5.1 Sidetone Level (AA30-014 only)
The sidetone level pots can be accessed through holes in the side of the unit.
When the pot is rotated fully counterclockwise the sidetone level will be at its minimum. Rotating the pot
clockwise will increase the level.
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.
2.4 Continued Airworthiness
Maintenance of the AA30-0xx is ‘on condition’ only. Periodic maintenance of this product is not required.
2.5 Accessories Required But Not Supplied
Installation kits are required to complete the installation. Different kits are required depending upon the
model - for information, please contact the Product Support Department at AEM.
2.6 Installation Drawings
The AA30-013 is described as an example of a single user unit, and the AA30-014 as an example of a
dual user unit.

Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the AA30-0xx
Expansion Panels.
The AA30-013 is described as an example of a single user unit, and the AA30-014 as an example of a
dual user unit.
3.2 General
The AA30-0xx Series are Dzus-mounted expansion panels designed to expand a single transceiver
selection from an audio control panel to allow three transceiver selections.
These units are generally part of a larger system with other audio controllers or equipment; the whole
system must be considered, not just the AA30-0xx accessory unit.
3.3 Controls and Indicators
The controls on both the dual and single user versions of the AA30 work in a similar manner; for
simplicity, only one set of controls will be described.
