Hi. I'm new here just to let everybody know. I need some help with what everything does like the equalizer, processer, and all that kind of stuff. I'm not new to the audio world. But I am kind of new. I came across this web site trying to find how all the stuff works, why I need it, how it helps etc. Right now I just have a sony home theater system that I like alot but I want something nicer because I live in a apartment and am curantly buying a big house and I would like to hear the music when I'm cleaning up stairs or working. Could you guys please help me with this. I need to know like how the amplifier works, the processer, reciver, equalizer, how it the stuff helps, just stuff like that. I know car audio but this stuff is new. All the help and input is wanted. Thanks.
