Local mute is a common PA function where one or more speakers are disconnected when a specific access panel is used. This is commonly used when there are a high probablity of feedback.

Assigning Local Mute to a Control Output
To assign the function Local Mute to an Control Output:
- In Components view, open Output Actions
- In System, identify the Controller, the Amplifier or the Access Panel to be used, and expand to Device > Control Outputs.
- Drag Local Mute to the Control Output you want to use.
Configuration example
When a specific Source sends audio to a specified Zone, the output will be operated
The output is used to mute a nearby loudspeaker
- Drag Local Mute to the desired Control Output.
- Select the desired source in Source.
- In Zone select the zone that the desired speaker is part of.
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.
Parameter details
Idle State: Sets the idle state for the output. The options are Normally Open or Normally Closed
Delay Activation: Delays control output activation for the stipulated number of seconds when triggered.
Source: The source that will trigger the alarm output. The Source field can contain audio inputs, access panels and local mute control input actions. The Local mute 'id #' options refer to the local mute control input action that can be assigned to a DAK or a control input. If Source is not specified, it will be ignored when checking whether the conditions for the audio activity triggering are present or not.
Zone: The zones in which the output on an activity is triggered. If Zone is not specified, it will be ignored when checking whether the conditions for the audio activity triggering are present or not.
Advanced Options:
- Limit High Not OK: When the Control Output is cleared, and feedback voltage is at or above this value, the output is considered fed with alien voltage.
- Limit Low OK: When the Control Output is set, and feedback voltage is above this value, the output is considered active OK.
