Mute audio

when RCA/3.5 mm is used, see

proceeding.

Mute audio
You can mute any audio input port using the Admin panel. For analog audio ports that are configured as
mono inputs, you can mute each port separately.
Some audio input ports share internal audio processing resources in the Pearl device. Muting an audio
input that shares internal resources mutes all the associated audio sources. The following table lists the
audio input ports that share internal processing and the results of applying mute.
