[QUOTE="Vinny D'Agostino, post: 882, member: 112"] Itech 8000 update & input gain question I worked my first show with my newly aquired IT8000 running my complete system: (2-QRX218s & 2-QW3f) My first noticeable improvement was how much easier it was taking the amp rack out of the truck with just the single IT8000 in it! Overall I liked how the system sounded, the subs were noticeably improved from how they were being run previously (RMX4050HD & Ashley XR1001 crossover) I don't know if it was just from the amplifier switch to the Crown or the way how I have the IT crossover and filters set, but it was a big difference. The amp chugged along all night with ease but there was only one minor issue that I need to correct/adjust. From just testing in my basement with an ipod it seemed like I had the input gains set correctly and getting all the power I needed would be easy.....well, not so much. With finally getting to play around with a live band I noticed something needs to be changed in the gain structure as I was really having to drive my A&H MixWiz hard to get enough output from the amp. Way harder then I have ever had to (were talking flashing red lights on the output meter). I haven't pulled the amp out of my truck yet but I just checked System Arch. to see how the amp was set. Here it is: Input Sensitivity 1.40volts Input Gain 39.4db What should I look at changing so this amp see's a stronger input voltage? The amp was certainly loud enough when I was pushing the board hard, it was still only flickering the -20db lights, so there is plenty more power in there for me to get at. Thanks, Vinny [/QUOTE]
