Wrote a piece about graphic EQs on my homepage, it's in Norwegian, but the pictures should be in Esperanto 
Enjoy.

Re: Some measurements of a graphic EQ
I bet some little kids would enjoy playing around with that setup, seeing what kind of landforms they could make!
I find the adjacent cutting/boosting filters very interesting. The result is as if a mountain range is leaning over. I wonder how it sounds??

Re: Some measurements of a graphic EQ
Sometimes I wish a graphic EQ would be able to solve ANY issue on FOH or MON. It never does. ANY brand or ANY kind. It's just a hype or a myth, overblown by retarded riders. Please, find a strength to strike them from your ideology. (back then on PSW and still now from time to time, a guy comes by and lists his equipment, almost starting with some sort of graphic eq ... I mean ... what does it say about you or your system ... In my book : "Please, don't hire me!"

If your problem can be solved with a graphic EQ, you are the luckiest person in the world, but, wait a minute, that is me already. Lose it, you'll feel better.
Still, Helge, the effort is what counts.

Re: Some measurements of a graphic EQ
What does this mean? A graphic eq is an effective tool that is utilized by most audio engineers on a nightly basis, myself included. While I tend to eq the house with a parametric these days, I can certainly have a great show using a graphic to tune a pa. I still tune monitors with a graphic. It DOES solve my problems - which are making a living and satisfying the needs of the band.

Re: Some measurements of a graphic EQ
Graphics have their place, that place is with band mixers not systems engineers. I don't think there is anything wrong with that either.

Re: Some measurements of a graphic EQ
What happens if your both the band engineer and system engineer ???

Re: Some measurements of a graphic EQ
+1... GEQ are the equivalent of MASH surgery during wartime... When you are in the trenches doing hand to hand combat with feedback it is a faster/easier tool than Parametric EQs.
From my unified (Johnny) theory about feedback, we only need a handful of bands with relatively narrow bandwidth to manage the feedback beast (for simple mic/speaker path). I have even built swept notch filters into a monitor console for this purpose. I even had a variation on FLS that worked with parametric sections (and parametric based notches) to use LED indicators to steer you towards the loudest signal, presumably the feedback (also used in that old monitor console on the notch filters).

better yet, get some of these...

Use both types of EQ!~:-D~:grin:

Re: Some measurements of a graphic EQ
Nice analogy!
On a recent gig of mine designed with somebody else's gear, I chose not to use the six channels of graphic EQ he brought. He was dumbstruck. I used digital parametric EQ via DSP and got the rig sounding much better, I think than it could have otherwise. The boxes had a bunch of problems that fell between ISO frequencies.

Re: Some measurements of a graphic EQ
Nasty boxes. If only someone would build boxes that have problems at ISO frequencies only. ;-)
I used to mix on a Midas Legend a lot and I was never using GEQs for monitors or the PA. The parametrics on the busses were just what I needed, the PA was handeled on the system controller.
