SECTION 1 - DESCRIPTION
1.1
System Overview
The JA10-070 Audio Controller - Ten Transceiver with RX Volume Control is part of an aircraft audio system
consisting of an audio controller and an optional control
panel
.
The audio controller distributes and controls all transceiver and receiver audio in an aircraft. It routes microphone
audio to a selected transceiver and distributes all intercom audio.
The USER 1 operates the audio controller via the front panel controls. The USER 2 operates the audio controller via
the optional control panel
.
The audio controller can be used in a stand-alone configuration (one audio controller).
An emergency operating mode connects USER 1 to the COM 1 transceiver, the NAV 1 receiver and all four direct
inputs, and USER 2 to the COM 2 transceiver, NAV 2 receiver and all four Direct Audio sources.
The JA10-070 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. To
facilitate future customizations and certification, neither software nor complex electronic hardware is used in the
JA10-070 design.
