JA39-075
The JA39-075 Low Impedance Headset Adapter allows a low impedance
headset (75 Ohm Mic - 150 Ohm Phones) to be used with a regular aviation audio
controller such as the Jupiter Avionics Corp. JA95-001. The JA39-075 operates using
the Mic Bias supply of the audio controller and requires no other external power.
The JA39-075 unit features an industry standard U-174/U (TP-120) Plug and 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. It is particularly suitable for adapting 75 ohm headsets for use with the
Jupiter wiJAC™ Wireless Aircraft Headset Adapter.
WJ39-075
The High to Low impedance adapter is complementary to the JA39-075 and is
used to adapt the wiJAC™ JA61 Intercom Adapter to a low mic impedance (75 Ohm)
aircraft audio system.
The WJ39-075 unit features an industry standard U-174/U (TP-120) Plug and U-
92A/U (TJT-120) Jack to allow plug and play operation.
