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?

I should add, regarding the DAC, that the DEQ2496 sounds pretty good when used as an EQ with an analog signal as the input source via the balanced inputs. It's when I plug a CD player into it via toslink that things sounds mechanical. That is also when the input signal shows clipping on the meters. So, it's not clear to me if it's the DAC that sounds crummy, or if the input level being too high is the cause of the sound issues. However, since the input signal doesn't ride in the red, I lean toward the DAC as the problem.

Zapper, turn up the mic sensitivity in the utilities menu. Tvad is right, you don't need a blasting signal, but if your mic is set too low, it won't "hear" the pink noise.

I am having the problem of the input being to high as well. It is optical out of a Philips DVD player. I had to turn the Gain Offset in the Utility page down to -10 before the clip was not going off all the time. Is there a way to adjust the input, or is this what you need to do?

Yup. Me too.

The issue here is that the DEQ2496 is a pro audio tool, and pro source equipment has adjustable output gain whereas consumer units do not. In a pro audio setting, it would be easy to adjust the source output so the DEQ2496 input level was not clipping.

Tvad...I still suspect that your clipping is internal to the DEQ2496 (clip limiter) as a result of equalization. A 16 bit digital word input really can't saturate a 24 bit D/A unless your processing has led to an output of more than 16 bits.
If this is the case output attenuation should resolve the problem.

I have not used the digital input because my multichannel discs don't provide anything but analog.
