JA94-N44A Dual Audio Controller - AMS44 Compatible - NVG 

 

 

 

SECTION 1 - DESCRIPTION 

1.1  

System Overview  

The JA94-N44A dual audio controller is a centralized management system for two independent users that distributes 

and controls all transceiver, receiver and warning source audio in an aircraft. It enables the selected transmission of 

microphone audio to one or more transceivers and distributes all intercom audio. The JA94-N44A dual 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 Right User to the COM1 

transceiver and NAV1 receiver, and the Left User to COM2 transceiver and NAV2 receiver. 

 

The JA94-N44A 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 devices are used in the JA94-

N44A design.

 

1.2  

Features Overview  

The JA94-N44A may be configured as a drop-in replacement for the Cobham/NAT AA92, AMS42 & AMS44. 
The JA94-N44A supports up to 6 transceivers, each selectable from two rotary switches. 
The JA94-N44A supports up to 4 selectable receivers in two banks of 4 switches. 
The JA94-N44A provides intercom functions for up to 2 users and up to 6 passengers. 
The JA94-N44A has individual VOX gating for each user and passenger. 
The JA94-N44A supports two Direct Audio inputs at a fixed level to two users in Normal and Emergency mode. 
The Direct audios may be routed to both Left and Right User phones or Direct Audio 2 routed to Right User and Direct 

Audio 1 to Left User. 
The JA94-N44A supports a third Direct Audio input in Normal mode only. 
The JA94-N44A allows the receive audios to be disconnected from the Passenger Phones. 
The JA94-N44A supports two CVR outputs. 
The JA94-N44A allows transmit access for five crew members (Right User, Left User, Passenger 1, Passenger 2, and 

Passenger 6).The JA94-N44A allows ICS PTT access for all users and passengers. 
The JA94-N44A features a Music / Configuration connector on the faceplate 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 JA94-N44A has three modes of operation: Normal Mode, Emergency Mode and ICS Isolate Mode. 
The JA94-N44A supports radio simulcast. 
The JA94-N44A supports a remote transmit select input. 
The JA94-N44A supports selection of Normal Mode and Emergency Mode from a front panel control and selection of 

ICS Isolate Mode from an external switch. 
The JA94-N44A is NVIS Type I Class B compliant.
