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?

Its a while since I played with one of these, so I cannot recall how you might have the problem you mention but the unit is tricky to master till you play a bit and read that manual a few times. Perhaps the setting for the mic is wrong. The reason I posted is to say the unit works fine below 100Hz. You just need to be careful to do the measurements when there are no spurious low frequencies around - such as traffic noise etc, and take measurements in a few different spots in case the one you chose was a node or anti-node. The only problem below 100Hz is simply that a quick auto-calibration can give you strange results.
If you are including the low frequencies in the auto-eq, I think the problem is likely that there is relatively high and highly variable low-frequency background noise. You can reduce this problem by playing the pink noise at a high level during the auto-eq procedure, but you will likely be better off following their advice and using auto-eq only for frequencies above 100 Hz. Lower frequencies should be eq'ed manually, with the RTA providing some guidance but ultimately relying on your ears. Except for the auto-eq, my experience is that the DEQ2496 does an outstanding job for bass eq.
My bad - I had the EQ bypassed while trying to EQ! You are right about playing the pink noise at a high level to improve the S/N ratio. There was some low frequency noise visible at about -65 dB. I could hear it pulsing, and thought something was sending my subwoofers into oscillations, or the EQ was noisy. Turns out they are re-paving the Mass Pike not too far from my house. Just my luck!
Use independant measurements (RoomEQWizard, ETF, TrueRTA) and set the EQ manually. This might have been easier with RoomEQWizard software and BFD1124Pro.
