Primary And Secondary Audio Sources; Aux Audio Sources (Wired); Bluetooth ® Audio Sources (Wireless) - Bose A20 Guia Del Usuario

Primary and secondary audio sources

The aircraft intercom system (ICS) is always the headset's primary audio source.
When the headset is plugged in to the aircraft, intercom signals will always be
heard and cannot be muted by the headset.
In addition to the primary source (intercom), the headset can connect to secondary
audio sources.
Secondary sources can be either AUX (wired) or Bluetooth
Note: Only one secondary source can be heard at a time. Audio from a secondary
source will never override intercom communications.

AUX audio sources (wired)

Use the 1/8 inch (3.5 mm) AUX audio input to connect your headset with an
external audio source such as a portable GPS or a portable audio device. The
connector is located at the bottom end of the control module as shown.
Use the supplied 1/8 inch (3.5 mm) 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.
