Behringer DEQ2496 HELP

After reading the raves about this product, I finally bought one along with the matching microphone tonite. Put in my system, eager to try room correction. The first 2 attmepts produced some curves that I wasn't crazy about, but seemed plausioble. Now, all it does is push all the bands above 125 all the way to maximum boost, and all the bands below 125 to maximum cut. When displaying the RTA of the pink noise, there is nop more htan a 15 dB range between the highest and lowest levels on the curve (as if that were small!)Also, one of the primary reasons I bought it was for equalizing low frequency room problems, yet it suggests htat anyuthing below 100Hz not be included in the auto EQ.
Does anyone know why it is coming up with such odd equalization curves, even though it is reading the data, which doesn't look so bad? Also, how bad is the product at low frequencies?

And to add to Ecruz's observation, if your speaker can't do 20 Hz (and few can) set that frequency to -15 dB so as not to waste amplifier power and to avoid futile effort by the speaker.

Hi all, I have been following this thread in anticipation of getting my UltraCurve. Now that I have it though, :( :( :(

Why? Here is the message I posted to the Asylum this morning. If an expert here would like to pick this up, either here or via email, I would be indebted. Clearly this thing has immense potential, which makes non-success with it all the more frustrating.

I had the same problem when I first got mine and managed to solve it, but now I can't remember how. I will try to figure it out, but I think it has to do, as someone on AA suggested, with the overall gain settings you establish. Ambient noise does tend to be greater than you'd expect, at least has been when use the unit in my system. You may have overall gain set too high.

I think there would be a small but enthusiastic market for "DEQ2496 for Dummies." I'd pre-order and pay a premium, LOL.

Thanks Drubin. I wish to emphasize that the sound out of the speakers is loud when it says Ambient. This is most weird and certainly not desired behavior. Then, a few seconds later, when it states it is measuring Pink, it seems to me that it is adding a layer of a slightly different pitch on top of that sound. How loud is the original sound? Loud enough to be heard from two rooms away. Definitely NOT an oversensitive mic, as the sound itself is the issue.

Hope you and/or others can help me get this solved. I have sent an email to Behringer as well.

Kck...When measuring ambient noise (in the home environment) it should be dead quiet. I think that the ambient noise measurement may be important for pro sound applications where things may be going on while the sound guy is trying to get set up.

You might try using the analog output of the DEQ2496 into your amp. The D/A in the Behringer is probably as good as the one in the CDP, and one less item in the chain might help to isolate your problem.
