Dual Plug (General Aviation)

Dual plug models have two general aviation aircraft connectors that insert into specific jacks on the aircraft control panel.
NOTE: The microphone connector is shorter, thinner, and has a slightly different shape than the intercom connector.

Connecting to the aircraft

1. Insert the intercom connector into the intercom jack on the aircraft control panel.
2. Insert the microphone connector into the microphone jack on the aircraft control panel.

To disconnect from the aircraft, gently pull back on each connector to remove the connector from the aircraft control panel.

U174, 5-PIN XLR, and 6-PIN LEMO

5-pin XLR and 6-pin LEMO aircraft connectors provide the headset with both aircraft power and intercom audio. U174 connectors provide the headset with only intercom audio.

Connecting to the aircraft

1. Align the connector with the socket on the aircraft control panel, matching the narrow bar on the connector with the slot in the socket.
2. Firmly insert the connector into the aircraft control panel.

Disconnecting from the aircraft with the U174 and 5-pin XLR

1. Press the button/latch on the aircraft control panel to release the connector, if necessary.
2. Gently pull back to remove the connector from the aircraft control panel.

Disconnecting from the aircraft with the 6-pin LEMO

1. Pull back on the sleeve near the end of the connector.
   CAUTION: You must pull back on the sleeve before you pull the connector out. Forcing the connector out will damage the cable and/or the aircraft control panel.
2. Continue gently pulling back to remove the connector from the aircraft control panel.
