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?

RTA page 1 MAX and RANGE are just so you get a good display and will not have any effect on the EQ. You want to select MAX so that the display never hits the top, and you want to set the RANGE so that there will be something to see even during quiet parts of the music. Your settings will depend on the gain of the amps and sensitivity of the speakers, but on my rig MAX = -20, and RANGE = 60 works.
(MAX is negative, because it is dB down from the reference level. In other words, -10 is louder than -20).

If you want to roll off highs at 1 dB/oct hit the ROOM CORR button. Most people like this, but you have your choice.

If i run the auto eq and then double check it with my rat shack spl/Rives audio test cd, should it measure flat? I did this eq and it wasn't flat. Maybe i did something wrong.?

Streetdaddy...I have been down the RS meter/Rives CD, and with it I could never get the same results two times in a row. Perhaps it is a matter of exactly where you locate the mic or the meter. On the average, the RS meter results agreed with the DEQ2496, but were much more variable. Of course you should not expect agreement down to the last dB. The world is not that exact. I assume that you are using the tracks on the Rives CD which are supposedly corrected for the considerable errors of the RS meter. Also, I have heard that there have been several lots of RS meters, and all may not have the same errors.

I used the Rives CD (uncorrected) with the Behringer SPL meter function. The only downside is that I have to sit in front of the Behringer, which places me sort of in the way of things.

Ok, i think i did the auto eq correctly. I also hit the room correction button. When i toggle between the bypass and eq'd, the eq'd version sounds very muffled. Any suggestions?
