José is right on.
Before you can get the max benefit of the PAS you need to perform the “stage gaining” per their instructions. It’s a one-time deal. Once you set it, you can forget it.
All the PAS units come loaded with v1 of their presets. I didn’t begin to smile until I 1) tweaked the EQ within my kb and 2) then found the most appropriate preset in one of the channels (which, for me was # 05).
Then I downloaded the v2 presets and installed them. I found two new ones that really made me smile (55 & 57).
Then, at Gary’s suggestion, I ran L&R out of the kb and plugged into channels 1 & 2. WOW.
Placement of the PAS unit and its sub is also critical in getting the most of the system…and that can change with each venue.
I’m still learning…but enjoying it more everyday.
