Denon AVR-3805, i cant link the denon website to the product but, i'm looking at the photo images and the manual. I'm not sure how you equalize the sounds for this thing, currently i have a 2 channel denon receiver and i have pre-out and in hooked to an equalizer. If i wanted to equalize sound on a surround sound, is such a thing built in this?, or is there some other way of connecting equalizers. I'm not buying anything soon but i want to know about these things. Thanks if you can answer my questions.
