Does it restore them on every input...for example does it restore Cable, DVD, USB, etc... back to the original settings? Bat mentioned that Audyssey settings are input specific in an earlier thread. I would prefer to use my initial audyssey readings for every input.
you're confusing/conflating some stuff here.
the things which are "restored" when you go to Auto Setup > Parameter Check are only those basic speaker parameters listed in the Parameter Check. This is the fundamental system config -- what speakers are connected, are they large/small, distance, level, crossovers.
these are not "Audyssey settings" like whether you want Dynamic Volume on Day or Evening or Midnight mode, they are the basic config parameters that are the result of the Audyssey calculations during auto setup. The "settings" that are memorized by input are the specific "in use" settings like what EQ curve you use, whether you have Dynamic EQ on/off, etc.
so if you like to turn on Dynamic Volume with the Cable TV input, and you keep it off on the Blu-ray input, the "RESTORE" will not change this. But if you changed a speaker crossover from 40Hz to 80Hz, then the "RESTORE" will set it back to 40Hz.
So the RESTORE doesn't affect the "Audyssey settings" that are set (per input) in the Audio Adjust > Audyssey Settings menu
