Re ran YPAO 3 times with the same out of phase message on the 4 channels wired to my ADA1000.
The wiring is correct. Any chance RCA cables for video are different( I used left over cables from the satelite/PVR packaging)? I can't see it being the output on the reciever or the input on the amp.
I could swap the cables on one speaker and re run YPAO. Is there a risk of damaging speakers when used out of phase?
