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?

It does have an expander.

My latest observation is a channel imbalance which favors the left channel by 1-3db with the DEQ enabled. There is no channel imbalance with the tape loop bypassed (DEQ2496 is in the tape loop).

Tvad...How do you measure the imbalance? Did you create it by your EQ curve? 3 dB would be a fault condition for the electronics.

Imbalance is measured by the DEQ2496 meter...measuring both the input and output.

My EQ is in stereo mode, so there should be no difference between left and right.

What do you mean 3db would be a fault condition for the electronics? BTW, the imbalance has been betweeen 3db and 1 db depending on the recording.

I may swap the interconnects to see if the imbalance follows the interconnect swap. It might be traceable to the preamp tape outputs, but only a test will determine this.

I'll also go back into a previous memory preset and check the levels. Obviously, if they're not the same from preset to preset, then it points to pilot error.

When in DEQ mode, if you push the top small dial you go into a full spectrum gain mode. Tvad, is it possible you accidently raised the left gain when you were in dual mono mode? I think it would carry the imbalance on through when you switched back to stereo link mode in the utilities.

Gain in DEQ is/was set to 0.0. Thanks for the suggestion.
