Dood - I don't have the manual in front of me, but memory serves there is +/-12 dB on each band pass, allowing a 24 dB relative gain differential between band passes. That should be plenty? I sincerely doubt few systems are so far "out of the ball park" that this would not be enough. dbx aren't dummies in this. I was merely pointing out that your comment was limited in it's scope - it did not acknowledge there is ample gain accommodation, by band pass, available on-board.
