r-40 and Behringer 2496

JuanR · « **on:** 15 Jan 2006, 07:42 pm »

I just ordered a Behringer 2496, if someone know the ideal setting on the pods, like go all the way and let the eq to do the adjustment also any advise about setup.

You'll want to set a curve when you use the auto eq. You want a bit of a boost under about 350hz and a gentle slope from about 2khz on up being down 4-5 db at 20khz. If you let it do a flat curve it will sound unnatural being thin in the bass and bright in the highs. What you hear at a live concert is what you want.

The auto eq uses the graphic equalizer. Once that part is done use the parametric equalizer to fine tune. If you didn't order the Behringer ECM 8000 microphone you need to if you want to use the auto eq function.

It's wise to download the behringer manual and read it at least twice. The main things to learn are the graphic equalizer, parametric equalizer and the auto equalizer functions. There's alot more functions but I just turn them off.

Ask if you have any more questions and I'll do my best to help you.

Boost the range from 125Hz by 2-4 db with a slope back down to odb at 325Hz. Use a .5 db/octave attenuation from 2500 Hz to 20KHz. That is a good starting target curve. Once equalized (this assumes you are using the Behringer microphone and auto eq function), then manually add a 2db boost between 800hz and 1600hz with a 1db boost at 630hz and 2000hz. The microphone should be set up at your listening postion with it a few inches above your ear level and the mike pointing toward the ceiling to minimze a high frequency boost inherent in these types of microphones.
(This is a guideline from a Thorsten Loesch primer on room eqing using a digital equalizer, except for the microphone postion recommendation which was from an Enjoy the Music.com review of the Ultracurve).
You'll be very pleased with the results.

Thanks for the info, yes I did order the behringer mic. also I download the manual and I am int he second reading, but is kind of complicated. I will get it around friday.

Also make sure there's nothing reflective near your microphone including your listening chair. Move everything away, tables or whatever.

Tweaker -- would you clarify your suggestions? Do you mean that the boosts and attenuations you suggested should first be added to the Berringer and then the microphone corrections superimposed on top of them? I also have this unit and quite frankly its complexity overwhelms me. Thanks

You want to let the Behringer do the auto eq on it's own, not on top of any other adjustments. You can set a curve that you want the Behringer to aim for. You will want a boost in the bass region and a taper in the upper region of the frequency spectrum.

You also want to set how much the maximum boost and cut it can do. I used 6db. Then go back and lower the boosts after it's done to no more than about 3db so you don't stress your amp/speakers. Leave the equalizer where it attenuated frequencies alone.

This is a good compromise and will yield very audible benefits in naturalness and balance. Do not let the Behringer correct the full dips and peaks as they could be 15db or more. There's more to this but it's too complex to get into here.

Before you do anything it's a good idea to play with the parametric equalizer and listen how the different frequencies sound. I have a tendency to estimate frequencies to being higher than they are in reality. Familiarize yourself before using the parametric eq.
When this is all done go back with the parametric equalizer and fine tune by ear.

Here's a rather fascinating article on creating target curves, written with the Behringer in mind but also adaptable with TacT and DEQX. I'm pretty sure I was originally pointed to this article by Tweaker. THANKS !!!

http://www.prijsindex.net/tmp/room acoustics and eq.html

Basically this is my target curve:

1. +2-3 dB below 125hz, returning to 0dB at 320hz
2. +1.5 dB at 1260hz, beginning from 0dB at 630hz
3. -1.5 dB at 2.5khz, returning to 0dB at 5khz

Above 5khz my target curve is drawn to overlap my measured response -- meaning no correction or EQ is being done and I'm listening to the natural response of the tweeters. Beyond 4khz my measured response rises to about +3dB @ 20khz. But this actually reflects a gradual roll off in the treble (-3dB @ 20khz) as the mic is increasingly sensitive above 4khz (+6dB @ 20khz) and this artefactually elevates the tweeter measurement. A mic with a very flat response, like the Earthworks M30BX, is on my future shopping list.

Eric,

That link does not work. I tried searching the level above (http://www.prijsindex.net/tmp/), but there's no indication of a room acoustics article. I also tried the link with no spaces and with underscores between the words. Still no luck.

Thanks! I was under the impression that this model had more than out set of outputs. Maybe I'm thinking of a different model?

warnerwh · « **Reply #11 on:** 18 Jan 2006, 01:21 am »

Bob: The DEQ 2496 has two sets of in/out digital outputs. It also has analog outputs x2.

Eric: Thanks for the link. Excellent article. Maybe I'll try a different curve and see what happens. Sound is so excellent now I honestly can't imagine getting much better. The bottom line I feel though is tweaking to perfection by ear.

Who wants to lend me their measurement mic for the weekend
