But in another spot in the manual I got the impression that MCAAC evaluates you rooms reverb characteristics and make a delay setting based on that when in Auto MCAAC. Either way I will listen to teh Auto setting (whatever that may be) and 30-50ms and see what sounds best in my room.

This really helped my 82 have more punch and kept the vol level lower (-30 vs -22, etc)

I would like to hear more opinions on whether or not 30-50ms is more beneficial in general. I have very flat speakers (Ascend) so I really don't think I want to take the reading to early and it still might be better to have it captured after room interaction

I'll admit that I still poke around with my SPL meter and various test tones (because I'm an inveterate tweaker), and sometimes store modified settings in one of the MCACC memories. But I keep reverting to the settings MCACC created after experimenting with my own for awhile.

Back to what I said earlier....try them out and see what sounds best in your room. I didn't see that much EQ differences in terms of EQ calibration adjustments when I used 30-50ms versus the default delay of 120-160ms. So I will probably compare default and 10-30 to see if i can get MCAAC to produce some noticeable differences.

I have a reverby room, so I want MCAAC to take into account the speakers, and some reverb. 10-30 didn't take reverb into account enough, and the default delay time took reverb into account too much. So 30-50ms was great for me, and I also preferred Symmetry to the other two. I did not juice the base, because I have come to prefer accuracy over boominess. The base is plenty with what MCAAc gave me and any more sounds slightly artificial. I did also activate THX Cinema mode, which adds some processing to what MCAAC already does. This mode really filled out the sound and added depth, richness, and power without distortion. I have no idea what it does but I like it. THX Cinema is not available on the US version, just the EU version I believe.

To summarize, the later the delay time the more it will thin out your sound. But the answer is not 0-20ms, because with a reverby room, you do want some thinning out, otherwise its a boom fest.

Did it change channel levels, too?

thx

Channel levels are not related to EQ calibration, so no, they did not change. But S-Wave and EQ change depending on delay time. I did auto mcaac custom....keep sp settings......and MCAAC checks your room for reverb and selects the appropriate delay time. I think. I know if you run straight auto mcaac then the delay is 120-160ms (or something close to that). But the manual hints that auto mcaac custom....keep sp settings....will check reverb of room and set delay. But I cannot be sure.

Again...what I did find (in my room at least) is that the lower the delay time.....the less attenuation of the lower frequencies. The longer delay time.....the greater the attenuation of the lower frewuencies. 125 hz most notably. There were some other changes throughout the frequency range as well. I liked 30-50ms. I have a reverby room, so I want attenuation....in the RIGHT PLACES. And that is precisely what MCAAC is great at according to my ears anyway.


I recommend running Auto MCAAC, then running Auto MCAAc Custom Keep SP settings. Then running advanced eq using 30-50ms and save all three correction curves (symmetry, fr align, all ch adjust)to three different presets, then compare. But I liked symmetry the best. That and front align was close, but there was just something slight smoother and more detailed in symmetry for me.

I would be interested in seeing your EQ numbers for 30-50ms against the default delay for auto MCACC. You can use "symmetry" if you prefer that one.

Thanks
