Miniature, unpowered equalizer.

[murphyslabrat]

I have seen some designs for DIY equalizers, but they're always huge. unfortunately, I'm not much of an EE, so I don't quite understand the diagrams enough to modify them, or to assess possible modifications.

I have a headset that can get quite loud, but the sound seems a little weird. So, my thought was to make an equalizer that only offers negative gain. My question is if anyone thinks I can build an equalizer small enough to fit on the side of a headset...that is, in a box taped (or otherwise secured) to the headset.

A second question is, where could I find a site that could explain electrical engineering principles to the point that I would be able to implement some of those diagrams, if not make my own modifications.

You can do what you want with just resistors and capacitors. Size is up to you . If you can work with surface mount parts it can be really small.

Dude, that is precisely what I need.
