Question about Audyssey and Equalizer settings
I recently bought an Onkyo TX-NR828 which I'm sure is very similar to the other models listed in this thread. My question is how the Equalizer settings relate to Audyssey. If I first set a manual EQ curve and then run the Audyssey setup, does Audyssey try to deliver my EQ setting as a "target response curve?" Or is the EQ added after Audyssey does it's thing to flatten the response (I don't think this is quite equivalent to setting a target). Or maybe the EQ only works when Audyssey is off?
Beyond this basic question I'm seeing some behavior I don't quite understand when I measure my system response (using Room EQ Wizard). My first measurement of my system showed a fairly flat response, and when I played with the EQ settings I could see minor changes here and there across the spectrum. Then I ran the Audyssey MultiEQ setup and measured again. This time it showed a 10dB hump around 16kHz. This is a puzzle on it's own (maybe the Audyssey mic is calibrated very differently?)... but the strangest thing was when I switched off Audyssey and re-measured -- the 10dB hump was still there!
Maybe I should take up this second question in the REW forum, but I'm wondering if any fellow Onkyo owners might understand this behavior. Is the Audyssey on/off setting only to control the Dynamic EQ and/or Dynamic Volume features, and the initial setup is kept as a baseline that's in effect at all times? (And maybe the manual EQ is an adjustment on top of this, answering my first question.) If this is the case, how do I reset Audyssey to be completely disabled?
Thanks for your help!
