What are you talking about?
MCACC does not set itself automatically hence the word "Manual". Ofcourse there is more to setting up a receiver than MCACC when I come across any problems with other settings I'll let you know. For Now we are talking about a VSX-D814-s's MCACC system in a beginner forum. So go easy champ.
Thanks for the link to your elite hardware it helps me out greatly.
Getting back to the topic, there is nothing in the manual that cleary explains where the tones should be considered in "tune" when calibrating the speaker distance. I can only guess that the two speakers should be sound equal from the listening position
