okay...a few months ago i sold off my hartke 3500 to get an ampeg svp pro, and a qsc rmx 850. i figured the 850 would be fine for me, seeing as i would be running it bridged into 4 ohms. i basically wanted more power and better tone. well...the tone is there, but the power isn't what i was expecting. i was figuring that 830 watts compared to 350 watts would be noticably louder, and it's not. i have the speakon wired correctly, and the switches on the back of the qsc set up correctly. my main question now is, does the svp put out enough power to drive the qsc to it's fullest power? or do i need some kind of signal booster? right now i just have my tuner, svp, and qsc in my rack. i'd have to replace my tuner with something i guess (i'd rather not, but if i have to...). is this what the problem is? thanks.
