I had an issue with my SB4000 staying on all the time. It seemed to be picking signal up from somewhere, so I bought another trigger manage the sub. Previously, I was not using the trigger and it was never an issue. At first it didn't seem to be working, so I went back behind and pulled the triggers to swap 1 and 2 and I arced on the chassis of the XPA-5 because I was dumb and forgot to turn it off. Now the trigger does not work at all. I tried trigger 1 and 2 on the sub and both work, so it would seem to be an issue on the amp's trigger. The amp works fine, just no trigger.
