RE: eq post or pre active crossover?

For live P.A. use, would you recommend placing graphic eq's post active crossover signals. E.g. a graphic each for the low, mid and High?

I am not sure if it would offer any benefits?

Thanks , J. smiley20

I think EQ before the crossover is better. Less chance of messing up the phasing of the speakers at the crossover points.

i use digital lms units where on most..... you can do pre and post eq'ing. Most of the eq'ing is done pre crossover, but some times i allso add or minus a bit post eq but try not to eq around xover points when using post eq..... A combination of both i guess...... but more on the pre side.

The only post crossover EQ I use on my DCX2496 is some CD horn EQ for the compression drivers.

I had been lying in the bath, as I could not sleep the other night and pondered over post eq's.

I haven't used a Digital LMS yet but, I am using the Berry DEQ at the mo. It is excellent for letting you know which freq's are causing feedback, but you have a tendency to start watching it too much.

It seems to have a good low & high filters built in and the gate/limiter is handy too. The only slight issue I have with it is that it only has 1 x 31 band sliders. It would have been amazing with two separate sets.

Thanks Bee & Xoc1.

thats where post eq would come in handy.....

Regarding pre or post eq. in general, the x/o has to be the last in the chain to act as the dividing network for your amps and speakers and regarding frequency bands, normally the graphic would sort everything out, because the hi end of the eq would sort out the horns etc. In other instances where you use the graphic for 'room only' correction then that could be a case for Band eq.

A Parametric EQ with Notch Filters would be very interesting put in after the x-over to flatten out
or boost the frequency response of the x-over bands in the speaker system just like some system processers.
I agree with previous posts a graphic just isn't accurate enough.

phillip this is possible but only with the high end lms units..... had a chance to see the new bk lms unit tonight, very nice, think i wold like to have a play with one a bit more......
