Hi all, I've got these active speakers that are hooked up to a preamp for volume control. The problem is when the speakers are set at 0db, the preamp will max out the speakers with hardly any knob turn. Starting at 7 o'clock, it'll max out the speakers at around 10 o'clock. Hardly any room to adjust volume. As soon as I take the speakers into -db, it distorts like crazy with the preamp. Any solution to this?
