The wiJAC™ Wireless Dropcord System consists of two
components which provide a wireless full-duplex audio link between the
aircraft’s intercom / radio systems and the user’s headset. Adapters are
available for different headset connector styles. The JA69 component plugs
directly into the aircraft audio system via a standard dropcord jack and the
JA68 component connects to a standard aircraft headset and attaches to the
user’s belt. Together the two separate components allow aircraft personnel free
movement both inside and outside the aircraft. The headset adapter features
only essential controls to ensure ease of operation. As well as VOX and Volume
controls, the JA68 has two PTT buttons: one for ICS PTT and one for TX (Radio)
PTT. When TX PTT is activated, the microphone audio is transmitted to the
aircraft audio controller and then to the selected aircraft radio.
