If you have connected one or more secondary audio sources to the headset, you must decide how you want to hear those secondary sources. To select how you will hear your secondary audio sources, use the Secondary Audio Mode selector on the control module.
- A20® Aviation Headset
The selector has three positions: MUTE, MIX and OFF.
Intercom prioritized over any secondary audio sources
If an intercom signal is detected, all secondary audio sources are temporarily muted. Secondary audio will return after intercom audio ceases.
Intercom mixed with any secondary audio sources
All secondary audio sources are mixed with the intercom audio. Audio from a connected device will keep playing during intercom communications.
Note: In MIX mode, you will hear a maximum of two audio sources - the intercom plus one secondary source.
note: in off mode, bluetooth® power is disconnected, and all antennae are disabled.
only intercom audio is active. all secondary audio sources are off.
note: if you switch to off mode while connected to a bluetooth source, you many need to re-establish your bluetooth connection the next time you turn on the headset.
Note: Only one secondary source can be heard at a time. Audio from a secondary source will never override intercom communications.
note: incoming and outgoing phone calls automatically mute all other secondary audio sources when the secondary audio mode selector is in either the mute or mix position. during a bluetooth phone call, the intercom and the phone call will be heard as mixed.
