SECTION 1 - DESCRIPTION

System Overview
The JA34-001 Universal Radio Adapter allows the aircraft audio management system access to a non-aviation radio.
The JA34-001 provides fully isolated audio signal paths to and from the radio to allow a noise-free installation.
Microphone biasing and artificial sidetone generation are selectable for radios without them.
The JA34-001 is setup on a 'per installation' basis using cable CAB-USB-0002 and the JA99-001 Configuration Cable,
or cable CAB-USB-0006, and downloading the system configuration settings from a PC into non-volatile control
devices.
