J301A-001

Audio Controller

SECTION 1 - DESCRIPTION

1.1

System Overview

The J301A-001 audio controller is a centralized management system that distributes and controls transceiver,

receiver and warning source audio for one user in an aircraft. It enables the selected transmission of microphone

audio to a transceiver and connects to the intercom audio bus.

The J301A-001 audio controller provides a passive emergency mode that directs the user to the COM 1 transceiver,

NAV1 receiver and all Direct Audio.

The J301A-001 is set up on a per-installation basis using a configuration cable and a PC running the product

configuration tool to download system configuration settings via the front panel music / configuration connector.

1.2

Features Overview

The J301A-001 has a 15 pin D-Min connector, which interfaces to the Direct audio and ICS Tie lines, a 50 pin D-Min

connector which interfaces to the Radios, power and user headset connections, and a 25 pin D-Min connector which

interfaces to music and extra transceivers. This layout follows industry standard interconnects for single-user single

transmit selector audio controllers. The front (faceplate) subassembly contains the user interface.

Numerous input and output levels are adjustable, several audio paths are selectable using the configuration tool

ProCS™ (Product Configuration Software) to write configuration commands via the JA99-001 configuration cable to

the front panel music / configuration connector.

The J301A-001 supports up to eight transceivers, each selectable from a rotary switch.

The J301A-001 supports up to six receivers.

The J301A-001 has intercom VOX operation.

The J301A-001 supports four Direct Audio inputs to provide audio at a fixed level to the user.

The J301A-001 has a CVR output.

A Music / Configuration connector is provided on the faceplate of the J301A-001 for configuration of audio levels and

routing. The connector can also be used as a music input and is compatible with most music players.

The J301A-001 has two modes of operation: Normal Mode and Emergency Mode.
