Audio Activity

Visual indication of Audio Activity

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

The Audio Activity function is used to trigger the control output on audio activity in the indicated zone(s).

Audio Activity is a basic function that can be used for most activities.
The different options are based on an internal OR logic (i.e. one of the selected Zones, or one of the selected Sources, or one of the selected Audio Types). After that, AND logic is used for Source, Zone, Priority Range, and Audio Type.

Assigning Audio Activity to a Control Output

To assign the function Audio Activity to an Control Output in EMT:

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