Connecting to the GPI port
Connect to pin 2 for the microphone trigger or system mute trigger (depending on the
configuration chosen), or pin 3 for the line in trigger.
Isolated connections should be between the input pin and 0V to trigger, and +5V to clear.
Non-isolated connections should pull the input pin to 0V to trigger and pull up to a maximum
voltage of +15V to clear. Make sure the ground (0V) is connected for reliable operation.
When triggered, the “padlock” LEDs will flash, and the “ON” button of the triggered input. If
the padlock LEDs flash on their own, this signifies a “System Mute”.
