Trigger an ON AIR light
An Air light traditionally is illuminated when a microphone is ON. Additionally, the console has
logic built in which will mute the monitor speakers if a localized microphone is ON. The Control
Room (CR) speakers have GPIO logic built into the product. This logic is as follows.

OUTPUTS

TALK (to CR) Active Lamp
The first output is the ON AIR lamp and is illuminated anytime the CR monitors are mutes. To use
this logic to trigger a light circuit is as follows;
1. Within a show profile configuration editor,
select Monitor Section.
2. Within the specific profile's Monitors
section, locate the Logic port for the CR
Speakers. Here you should enter a unique
Livewire channel. A common practice is to enter the same number that is used to define
the CR monitor speaker audio.
