correct, care needs to be taken not to over extend headroom in the amps by adding gains and such. Don't worry, been down this path many times before with the DEQ2496
My room has a couple of nasty nodes that audyssey was never (has never) been able to fix. my new processor (marantz av8801) has audyssey xt32 and sub HT, and does a much better job than before, but still need to accomplish:
1. adding L/T circuit to boost the low end.... remember, I'm driving quad 18' sealed subs.
2. mitigating the nodes by leveling off the gains.
I'll post the charts when done, but you can see what i achieved with the DEQ2496 with the same setup, prior to it going 6ft under:
