Section 1 Description

1.1 Introduction

This manual contains information on the AA30-301 Expansion Panel. All derivative
products will be covered by manual supplements, which can be obtained from NAT as
required.

Information in this section consists of purpose of equipment, features and specifications.

1.2 Purpose of Equipment

The AA30-301 is a Dzus-mounted 4-transceiver radio receiver expansion panel,
designed to work in conjunction with the 380-series Audio Selector Panels.

1.3 Features

The AA30-301 provides four ganged transmitter selector pushbutton switches and four
receiver level panel potentiometers, each with an integral push-in / push-out selector
switch, and utilizes the subassembly from a 247 Audio Mixing Amplifier for signal
mixing, amplification and processing.

The AA30-301 is designed to be used in conjunction with a 380 panel to expand a
single 380-series transmit microphone output into 4 outputs, and to expand a single

AA30-301 Expansion Panel Manual SM74 Rev. 4.10

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 receive audio lines used in the AA30-301 installation is
very critical and poor performance of the aircraft audio system will result if the
installation shown on Interconnect drawing AA30\301\403-0 and -1 is not followed.

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 Voltage/Resistance Checks

Check the following:

a) P101 pin <13> for +28 Vdc avionics buss voltage.

b) P101 pin <12> for +28 Vdc lighting buss voltage.

c) P101 pins <15> <16> <18> <20> <22> and <25> for continuity to ground (power).

d) P101 pin <24> for continuity to ground (lighting).

2.3.4.2 Power On Checks

WARNING:

High volume settings can cause hearing damage.

Set the headset volume control to the minimum volume

setting prior to conducting audio tests, and slowly increase

the headset volume level to a comfortable listening level.

Section 3 Operation

3.1 Introduction

Information in this section consists of the functional and operational procedures for the
AA30-301 Expansion Panel.

3.2 General

The AA30-301 Expansion Panel is a Dzus-mounted 4-transceiver or radio receiver
expansion panel, designed to work in conjunction with the 380-series Audio Selector
Panels.

3.3 Controls and Indicators

The AA30-301 provides four ganged transmitter selector pushbutton switches and four
receiver level panel potentiometers, each with an integral push-in / push-out selector switch.

The laser-engraved text of the faceplate and any selected transmitter or receiver control
is illuminated when backlighting power is supplied to the unit.

3.3.1 Transmitter Selection

The transmitter control switches are four push
switches that are used to select transceivers fo
transmission.

When the transmitter control switch is the extended (out) position, the corresponding
transmitter is deselected (off), and the integral mechanical annunciator appears black
behind the clear window, and when the transmitter control switch is in the depressed
(in) position, the corresponding transmitter is selected (on), and the integral mechanical
annunciator appears green behind the clear window.

The default position for all transmitters is deselected (out).

The transmitter controls are designed to prevent accidental selection of more than one
transmitter; pushing a transmitter control switch locks it into the depressed (in) position and
cancels any previously selected transmitter control by returning it to the extended position.

Oct 16, 2006 Page 3-1

ENG-FORM: 806-0106.DOT

CONFIDENTIAL AND PROPRIETARY TO NORTHERN AIRBORNE TECHNOLOGY LTD.

AA30-301 Expansion Panel Manual SM74 Rev. 4.10

r

j

All transmitters may be deselected by partially depressing any unselected transmitter
control.

When a transmitter is selected, the mic key and mic audio signals are automatically
directed to that transmitter.

A selected transmitter control bypasses the corresponding receiver control selector
switch (see section 3.3.2) to provide an auto-receive function.

3.3.2 Receiver Selection

The receiver control switches are fou
push-on/push-off rotary switches that are used to
select receivers and ad

ust volumes.

3.3.2.1 Selection

When the receiver control switch is in the default depressed (in) position, the
corresponding receiver is deselected (off), and when the receiver control switch is in the
extended (out) position, the corresponding receiver is selected (on).

The default position for all receivers is deselected (in).

The auto-receive function automatically selects a receiver for audio when the
corresponding transmitter control is depressed, even if the receiver control is not in the
selected position.

Receiver controls are independent; any combination of receivers may be simultaneously
selected.

3.3.2.2 Volume Control

The volume for each receiver can be adjusted by rotating the corresponding control.
The receiver volume is decreased to minimum at the full counterclockwise (ccw) stop,
and increased to maximum at the full clockwise (cw) stop.

If a receiver is activated by the Auto-receive function, the level is set by the current
receiver volume control, even if the control is deselected.
