How do EQ characteristic work on a mixer?

Ok in the process of 'mixing' on my Behringer XENYX2222FX Mixer. How does say turning a knob (lets use the one labelled 'LOW 80Hz' that has a range from -15 to 15) work in a graphical sense. i.e, what happens to the EQ pattern visually when I turn it towards + or - 15? My other EQ knobs are 'MID FREQ: 100 to 8K, MID -15 to +15 and HIGH 12kHz -15 to +15. If anyone could help me understand what happens when I turn these knobs in relation to say a graphic equaliser or visually so I can picture whats going on in a cutting/boosting frequency sense, that would be a great help. Cheers, Boe

Just use your ears. Trust me.

basically when you turn the knob up or to the right or + you are boosting that frequency and turning the other way is cutting..

using your ears is good advice though.

try just playing a cd track and messing around. you can learn a lot very quickly that way.

Uh, at least one more time . . .

To get a really good visual sense of this, check out a virtual EQ in your average DAW. In mine, the four band EQ is displayed "closed" to look like your typical EQ--4 knobs, with the bandwidth in numbers next to each knob. Right click on it, and it diplays it graphically, with numbered dots on a scale, along with details below, like Q values and filter roll-off icons (those little hook and bump buttons)(Magix v. 12) This visual representation gives me a much better idea of what frequencies are doing what on our Behringer 2442A
