Just picked up what appears to be a great aid in answering a lot of the sound and amplification questions this post has generated.It's called Live Sound Reinforcement by Scott Hunter Stark,purchased at B@N books $29.95.It covers all topics and contains the ever necessary eq spectrum list from 40hrtz to the top end and all types speaker placement and effects. As for me on the KC500 all knobs at 12 o'clock as a starting point and eq on rhe mixer side with alot of audiance feedback at the onset of the gig. I am thinking of adding 2 of the new Kc60s on the sub out side of the 7000. Tried 2 Fostex mini monitors with r1 and acc.on,results were astounding but needs some more power to keep up with the system wattage.The mini Moog on the line in sounds great too but I think it's overkill as the 7000 has more than enough tricks up it's sleeve to give that a run for the money.Well enough for a novice poster I have really gained a lot reading thru the posts an am very gratefull. Thanks Jaxsax
