JA39-xxx - In-Line Headset Adapter Series

Data Sheet

JA39-xxx

The JA39-xxx series of in-line headset adapters allow a variety of headset types
and impedances to be used with a regular aviation audio controller such as the Jupiter
Avionics JA95-xxx series. The adapter operates using the Mic. Bias supply of the audio
controller and does not require any external power.

The units feature an industry standard U-174/U (TP120) Plug and a U-92A/U
(TJT-120) Jack to allow plug and play operation.

The metalized plastic case construction allows the adapter to be used in high RF
environments. The in-line adapters are particularly suited to adapting different headsets
for use with the Jupiter wiJAC2™ Wireless Aircraft Headset Adapter.
