as the saying goes " the more you learn, the less you know "

I am currently using the following components for DJ use:

2 B-52 PA315
2 Crown XTI 1002 (  one amp for right one amp for left bridged at 8 ohms. in bridged mode, with Y input seleced, amp A ch 1 gets left signal amp B ch 1 gets right signal )
1 DriveRack PA+
1 furman AR-1215 AC LINE VOLTAGE REGULATOR that everything is plugged into ( which i now think is useless )( including a labtop and a cheap alto 5 ch mixer ) ( which i now think is useless )

I just started messing around with the Band Manager 2 and i noticed that my inputs were next to clipping but my outputs were nowhere near clipping ( more like 1/4 of the way up the meter max ). so after beating the internet to death with google and finding the corrolation with the gain knobs on the front of the amp now the output is a bar or two under the input and no clipping. even tho the knobs on the amp are 3 and 4 clicks away from being at 100%... is this a correct and or safe way to do this? also by doing that, i started to notice a hiss... so i started by unpluging the inputs and the hiss was still present.. i have only had these amps for 3 days and the clip lights have only " bliped " while setting gain structure the first time ( which produced the insane inputs with the low outputs ) and the second time i did a redo on the gain structure to use more amp power. my reading im afriad to get the answer about the hiss.. i would like a dead silent system with nothing playing but if its not hurting anything when music is being played then i will not worry about it. i also have a B-52 PA18s otw that will be powered by an XTI 2002 bridged at 8ohms..  i was told to go for the 6002 and the 4002 but i didnt have the money or the 20 Amp socket ( how many places have 20A circuits? ) while on the subject of amps and outlets and voltage... that furman AR... is that suposto keep whatever is plugged into it with a constant supply of 120 volts? when i was testing my system today while looking at the voltages in Band Manager they were dropping to around 110 or so.. so whats the voltage regulator even doing? did i waste my money on it? or can somebody suggest something better...

thanks :-)
