Help with EQ! I'm a newb, so be prepared.!

I need a little help. I just bought a pxa-h510 (older Alpine Processor), in MINT condition, for a really good price, but I'm clueless when it comes to EQ's.

Heres it's specs:

Parametric-EQ Number of Bands

Front: 4, Rear: 4, Center: 2, Subwoofer: 1

Equalizer Center Frequency Range

Front and rear

Band 1: 20/25/31.5/40/50/63/80/100/125/160/200/250/315/400/500/630 (Hz)

Band 2: 63/80/100/125/160/200/250/315/400/500/630/800/1k/1.2k/1.6k/2k (Hz)

Band 3: 200/250/315/400/500/630/800/1k/1.2k/1.6k/2k/2.5k/3.2k/4k/5k/6.3k (Hz)

Band 4: 630/800/1k/1.2k/1.6k/2k/2.5k/3.2k/4k/5k/6.3k/8k/10k/12.5/16k/20k (Hz)

Center

Band 1: 100/125/160/200/250/315/400/500/630/800/1k/1.2k/1.6k/2k/2.5k (Hz)

Band 2: 315/400/500/630/800/1k/1.2k/1.6k/2k/2.5k/3.2k/4k/5k/6.3k/8k (Hz)

Subwoofer

Band 1: 20/25/31.5/40/50/63/80 (Hz)

I just don't really understand what a 'band' is and why there are four for the front and rear speakers? Why do the bands over lap each other?

Again, I'm a total newb when it comes to EQ's, so this purchase might be a little unorthodox (if that word fits here), but I gotta start somewhere.//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Presumably that's a parametric EQ. Which means you can select only one frequency per band to adjust, but it can be any one of the available frequencies for that band.

So for band one, you can select any one of those frequencies listed to adjust. Same for band two, and three, etc.

got cha thats what I thought. any suggestions on what not to do? I've been reading up for a couple of days now on how to opperate this unit, plus others, and have been getting little hints here and there, but I think its just gonna come down to me messing with it.//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Main thing to remember is that EQ's should mainly be used to cut frequencies, not boost them. For every 3db of boost you add, it would required double the power from the amplifier.

Add that to my list. Anymore?
