The A20® Aviation Headset provides a 3.5 mm (1/8-inch) Aux audio input that allows you to use your headset with an external audio source, such as a portable GPS or audio device. The connector is located at the bottom end of the control module.
Use the supplied 3.5 mm (1/8-inch) adapter cable to connect your external audio device. Plug one end of the adapter cable into the headphone plug on your device and the opposite end into the headset Aux audio input.
Note: The control module will not control the functions of a connected device.
note: audio from an aux source will not be heard if the secondary audio mode selector is in the off position.
The A20® Aviation Headset allows you to decide the priority of the audio sources you want to hear while using the headset. See Setting the control module switches for more information.
