ok, so you can adjust the distance with no problems? I was thinking I read either on the Audyssey FAQ homepage, or on AVS that you couldn't. Wouldn't changing distance settings affect the frequency results Audyssey found prior? I know when I alter distance settings, it changes my graphs a little.
On my Denon 2807 you can change the distance, crossover and large/small settings w/o disabling Audyssey. However, the green light that indicates Audyssey EQ is on changes to red indicating that you have changed some settings. AFAIK you can’t change any of the EQ settings w/o turning Audyssey off as it‘s a specific EQ curve. There are other EQ curves “FLAT” “MAINS” “MANUAL” -etc… but I believe these disable the Audyssey curve completely as Mike said.
Yes changing any of the other parameters will change your frequency plots some more than others.
