Local Mute

Local Mute to prevent feedback

Control Outputs are configured by defining one or more actions to be triggered on an output event.

Local Mute is used when an output shall mute one or more speakers to prevent audio feedback.
Local mute is also used when there is a need to do a manual initiation of local mute with the input function Local Mute Control.

It is possible to define maximum 99 local mutes.

Assigning Local Mute to a Control Output

To assign the function Local Mute to an Control Output:

1. In Components view, open Output Actions
2. In System, identify the Controller, the Amplifier or the Access Panel to be used, and expand to Device > Control Outputs.
3. Drag Local Mute to the Control Output you want to use.

Assigning Local Mute to a Control Output

Configuration

When a specific Source sends audio to a specified Zone, the output will be operated

The output is used to mute a nearby loudspeaker

1. Drag Local Mute to the desired Control Output.
2. Select the desired source in Source.
3. In Zone select the zone that the desired speaker is part of.

Audio Activity configuration

In this example audio from the ECPIR-3P to Zone 1 will trig Control Output 1. This output can then be used to mute a speaker in Zone 1.

Example of use

It is possible to mute an IP Speaker based on a specified SIP Station doing announcement in Exigo.
This example can be found here.
