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

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
380-series receive audio input into 4 inputs.

The AA30-301 permits the audio system to support more receivers/transceivers than a
single 380-series panel is capable of individually.
