So I can use my existing pre amp into the xover and have volume control? I have heard that I would lose volume control through the preamp if using the Behringer. What is your experience? Are there any problems going from the balanced outputs of the xover to the unbalanced inputs of my amps? I have seen cabling that allows going from balanced to unbalanced (XLR/RCA) but have no experience with this type of set up. Any insight would be helpful. -Mike T.
