I know that.
I'm talking about the fact that it uses JPEG file type, which generally shouldn't be used for non-photographic stuff such as these charts/graphs, since it causes artifacts/smearing at sharp color transitions, etc. And by "PNG is smaller" I meant the filesize, not dimensions/resolution.
I also used 16 Averages.
I, like Chris, am stumped
It's very strange that this would occur.
It almost looks like there are different Audyssey filters used. Can you check what is set in the Audyssey menu while running each signal type?
I'm just wondering that maybe the AVR is changing from "Audyssey" to "Manual" or "L/R Bypass" depending on the input signal.
Though IIRC this is something that Denon does not change as part of it's input signal sensitive options. But there seems to be a completely different Audyssey curve for the two signals..........I assume you have ruled out other input signal sensitive processing options like Pro-Logic IIx Music/Cinema, or other DSP's............though I have already checked PLIIx and it does not cause such discrepancies.
It would be nice to get to the bottom of this, but as Chris mentioned you're probably better off contacting Denon to have it fixed/replaced.
Yeah, the MultEQ setting is per-input, and not dependent on input signal.
Before I sent it off to Denon, I wanted to try a DD 2.0 signal to see if it was still the same when simplifying things even more. I attempted to check with some recordings on the Dish Network DVR (to not use the PS3), but the stupid thing wouldn't output a PCM signal even when I set the digital out to "PCM Only" and removed the HDMI connection (signal support negotiation) for component/optical...
Oh well. So back to the PS3.
I checked the building explosion scene on the Rush Hour
DVD since it has a stereo track too (well, AVR shows 2/1 channels when bitstreamed). Yes, with MultEQ on, I still noticed a difference between bitstream/PCM -- not as much as other scenes, but depends what frequency the bass is at (and I didn't even compare the 5.1 track here). Again, Dynamic EQ shows the difference better -- more "rumble" with bitstream. Needless to say, I detected no difference between them with MultEQ Off.
As a final cannot-make-it-any-simpler test I switched to Stereo mode (yes, for both signal types
) to remove the PLII(x) processing. Same result!
Earlier last week, I was curious how a plain analog REW measurement of the subwoofer pre-out would look with MultEQ on, and if it would "match" the pattern of either of the digital multi-channel results. The front channel crossover was temporarily set to 250Hz.
(It was more "squiggly" than expected
, but I haven't moved the sub to a better place yet...)
Comparing the graph from my previous post
, the dips below 50 and 70 and the peak below 60 seem to follow the PCM result (certainly not bitstream!), but not so much otherwise. They should have a similar pattern right?
And yes, all measurements have been done with the same Audyssey setup.
