So, Fran, you must have plenty of volume out of your BA330. Mine never has been very loud. I don't expect it to shatter windows but it just seems under-powered. I assume that whether I am using AC or DC, it should be same output. Correct me if wrong, you know I ask a lot of dumb questions.

Yes, the Edirol mixer is a good one, I need to experiment with the room analysis feature.
