[QUOTE="Vinny D'Agostino, post: 23469, member: 112"] Re: IT8000 Update & Input gain question Okay, did a little more testing now that I have a lap top and can easily connect it to my IT8k. I setup my FOH rack & IT8k, i did not connect any speakers as I wanted to watch System Architect and see what was really happening with my input signal. I have come to the conclusion that the input signal not being strong enough is not my issue! From watching what was happening when the output meters on my MixWiz flashed the +3db yellow indicator SA was showing that the input source on Ch1 & 2 were clipping. So it would seem to me that I may need to reduce the input gain on the IT8k to avoid this, does that make sense? I also must add that I did change the peak voltage limiters and the RMS power limiters to reflect a continuous RMS level x 1.5 So I had the Subs set at 85v 1800w @ 4ohms (3600w @ 2ohms) The Tops set at 110v 1500w @ 8ohms (3000w @ 4ohms) I did set the band pass gain on the subs back to +6db So without having speakers tied into the amp there is no way to tell if the system is loud enough, my main goal was too see what was actually happening with the amplifier and my setup. So besides firing up the speakers and hearing whats going on what should I do about the input gain? I should also mention that while watching what was happening I never saw the output clip on either channel. [/QUOTE]
