With everyone else being equal, which scenario would you think would have more output or dynamics? Getting -10db and increasing to -2db, or getting -2db right out of the gates with post audyssey trim?
And, is it "ok" to increase the gain by 8db to get more output? Does this put the amp in a state of potential damage?I guess I still get confused on this whole distortion thing, what the sub is capable of doing, is the sub playing at what the audio mixers intended for us to hear, blah blah blah.
Thank you for taking the time to explain this!
This probably won't answer your questions, but I like to have the gain turned somewhat down when I run MCACC calibration on my system because of an issue I had with an earlier subwoofer. I had my old sub set to auto, but it wouldn't detect a signal until there was a substantial amount of bass in the signal. Then I would hear it kick on and start providing the low frequencies.
With the gain set relatively low on the sub, the AVR sets the channel level higher (arbitrarily I'll say -2 instead of -10). Because the sub channel level is higher, I think a more substantial signal is being sent to the sub, which should allow it to "wake up" with the auto on feature whenever content is playing.
If I wanted to maximize the sub output without regard to it matching the other channels, then after the calibration, I would turn the gain all the way up and set the trim as high as it would go. I wouldn't do that, though, because my goals for this system have little to do with bass maximization.
You bring up a good point, though, about whether it could damage the amp. My guess is that turning everything to "11" could cause problems. Try moderation - middle of the road gain setting and setting the subwoofer speaker level in the AVR within a few decibels of the auto-calibration. Or talk to the SVS guys. I hear they can be pretty helpful.
