JA95-N70 Audio Controller with RX Volume Controls - NVG
SECTION 1 - DESCRIPTION
1.1 System Overview
The JA95-N70 Audio Controller with RX Volume Controls - NVG is a centralized audio management system that
distributes and controls all transceiver, receiver and alert audio in an aircraft. It enables the selected transmission of
microphone audio to a transceiver and distributes all intercom audio.
The JA95-N70 Audio Controller with RX Volume Controls - NVG 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 (pilot) to the COM1 transceiver, NAV1 receiver and Direct Audio
receiver.
The JA95-N70 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 (♫/io)
without the necessity of removing the unit from the panel. To facilitate future customizations and certification, no
software or complex electronic devices are used in the JA95-N70 design.
1.2 Features Overview
The JA95-N70 features a 37-pin D-Sub connector, which interfaces with the radio receive audio and crew phones, a
50-pin D-Sub connector which interfaces with the power and passenger headset connections. This layout minimizes
crosstalk and follows industry standard interconnect for multi-user Audio Controllers.
Many of the input and output levels are adjustable, several audio paths are selectable, and alert audio analog
waveforms can be loaded using the configuration program ProCS™ (Product Configuration Software) to write
configuration commands via the JA99-001 configuration cable to the front panel music / configuration connector. The
audio waveforms are stored in non-volatile devices. The alert audio feature is intended for use as a secondary alerting
system where another device provides the primary annunciation.
The JA95-N70 provides intercom functions for up to seven users. It supports up to 5 transceivers and a PA position,
each selectable from a rotary switch, and up to 6 receivers (2 on each of 3 toggle switches).
The JA95-N70 features individual VOX gating, and supports one Direct Audio input to provide audio at a fixed level to
the users.
The JA95-N70 has a CVR output and a three channel Alert Generator. Each alert has a separate key input.
The JA95-N70 allows transmit access for four crew members (Pilot, Co-pilot, Passenger 1 and Passenger 2).
A Music / Configuration connector is provided on the faceplate of the JA95 for configuration of audio levels and
routing. The port can also be used as a music input and is compatible with most music players.
The JA95-N70 has two modes of operation: Normal Mode and Emergency Mode.
The JA95-N70 has Individual Receive audio volume controls.
The JA95-N70 is NVIS Type I Class B compliant.
The JA95-N70 has a discrete input to provide a Receive Mute function.

2.4 Installation Procedures
WARNING: Loud noise can cause hearing damage. Set the headset volume to minimum before
conducting tests, and slowly increase the volume to a comfortable listening level.
CAUTION: The power input circuitry of the unit may be damaged if the installation does not conform to the
wiring instructions in this manual.
2.4.1 Installation Limitations
The conditions and tests for CAN TSO and FAA TSO approval of the JA95-N70 are minimum performance standards.
Those installing the JA95-N70, on or in a specific type or class of aircraft, must determine that the aircraft installation
