Don't mean to crash the party, but I just wanted to add that I've put a DSP8024 between my preamp and the power amp bass channels in a biwired & biamped system with ML Aerius i's, and it works a treat for correcting my room's 80Hz resonance with -6db correction. Since my preamp has two pairs of outputs and the DSP8024 doesn't touch anything over 400Hz, I'm not worried about signal degradation - midrange & treble remain pristine.
The auto mic gain sets to +80db for Auto EQ even when the pink noise level is set to -32db, which is not loud but well above ambient noise. Not sure if this is relevant to the discussion about the DEQ2496. There is no auto level for pink noise on the DSP8024, and there is no indication in the manual or on any display regarding the appropriate pink noise or mic gain level. Still, it seems to work well.
