Question

How do I send Aux input A and Aux input B to Sub 3

Answer 1

1. Press the Aux In A/B Select button.

2. In the Fat Channel, assign Aux In A to Sub 3

If you are having any issues getting signal routed from the Aux Inputs to your assigned output, there may be an issue with your scene. Try recalling a Zero Out (Board Reset) scene and retest the issue.

Should the issue persist, create a support ticket from your my.presonus account.
