JA95-R03 Audio Controller - Remote Mount - One Transceiver
SECTION 1 - DESCRIPTION
1.1 System Overview
The JA95-R03 audio controller is a centralized management system that distributes and controls all transceiver,
receiver and warning source audio in an aircraft. It enables the selected transmission of microphone audio to a
transceiver and distributes all intercom audio.
The JA95-R03 audio controller can be used in a standalone configuration or a star configuration to prevent the loss of
the entire system due to the failure of one controller. It provides a passive emergency mode that directs the primary
user (PAX 1) to the COM1 transceiver, NAV1 receiver and Direct Audio receiver.
The JA95-R03 audio controller can expand one headset position to four headsets or can connect 7 headsets to an
ICS TIE line.
The JA95-R03 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 configuration connector. To facilitate future
customizations and certification, no software or complex electronic devices are used in the JA95-R03 design.
1.2 Features Overview
The JA95-R03 has numerous adjustable input and output levels, several audio paths are selectable, and alert audio
analogue waveforms can be loaded using the configuration tool ProCS (Product Configuration Software) to write
configuration commands via the JA99-001 configuration cable to the configuration connector. The configuration
commands set the level of non-volatile digital control potentiometers to control audio signal levels and to non-volatile
expander latches which are connected to audio gates to control the audio signal routing. The audio analogue
waveforms are stored in non-volatile voice record and playback devices. The alert audio feature is intended for use as
a secondary alerting system where another device provides the primary annunciation.
The JA95-R03 supports one transceiver.
The JA95-R03 supports up to one receiver.
The JA95-R03 has individual VOX gating.
The JA95-R03 supports one Direct Audio input to provide audio at a fixed level to the users.
The JA95-R03 allows transmit access for four cabin crew members (PAX1, PAX2, PAX3 and PAX4).
The JA95-R03 has a one channel Alert Generator.
The JA95-R03 has two modes of operation: Normal Mode and Emergency Mode.
The JA95-R03 Audio Controller provides intercom functions for up to seven users.
