Yes. When doing the auto cal, it is setting everything to reference. The only time you’d adjust the MV is when doing tones manually. If you’re doing that to double checK, or changing to taste. You would then set it to 0 and adjust speaker trims to hit 75db, or whatever your target is.
Deq is interesting. I personally don’t use it, or like it. I have a house curve I use with my minidsp, and deq raises the surround, and rear height/top levels too. HATE IT! However, our friend lovingthehd does use it, and has played with the RLO. Imo, do whatever sounds best for you. This is what deq “looks” like.
The RLO just changes the MV level at which deq kicks in, and you can see how raising the MV towards-0 lessens it’s effect.
As for sub trim at 11.5. I think that’s fine. That means you could raise it up to -7 or -8.(this would be common) The problem some subs have is when the trim is too low, the auto on function can be sketchy. Also, I’ve seen that being that low may not allow the subs amps to operate at full potential. It’s a gain structure thing, and I’ve never tested the theory. Only parroting what I’ve seen.
