Hey I just got a Sans Amp bass driver and can't believe the monster sound out of my amp . This is the holy grail I don't want to turn it off. The problem is some one told me I can't get this sound out of the pa mains if I use this in front of my amp and I had to use the rack mount one and go into the effects return and I thought I could as long as I use my xlr out on the back of my amp is this true? if so I am way bummed because I love the sound and I want this to go through the pa mains.
