Muffled Center Channel Output after Audyssey Calibration?

We have been discussing this issue in another thread:

I thought it warranted a dedicated thread. We are trying to figure out if this is a Denon issue or an Audyssey issue, or user error. We are looking for more people who have had (or haven't had) this issue.

Thanks!

I noticed it on my system too


turning up the level for the center helps some,

please post which receiver and version od Audyssey

My problems were with Denon AVR-1909 and AVR-1908 with Audyssey MultiEQ (non-XT).

 

[tattoo_Dan]

please post which receiver and version od Audyssey

I have a Onkyo TX-SR806 ,I don't know what version of the Audyssey it has,other than "multi eq/dynamic eq".

Here is a dedicated thread, with support by some top Audyssey guy I believe*. I do advise using the search function for a few minutes, so that you might not repeat an exactly similar question from before. YMMV though!

"Official" Audyssey thread.

I have a Onkyo TX-SR806 ,I don't know what version of the Audyssey it has,other than "multi eq/dynamic eq".

Its regular MultiEQ. Here is a little chart from Audyssey.

For me, the biggest downgrade of the 806 from the 805 could very well be the Audyssey version, IMO. Of course, take with salt as I'm a fanboi now, and once I implemented it in the HT, I started looking and asking for 2ch solutions for the stereo. This is after having implemented hundreds of pounds of treatments already between the two.

Bonus thread:
Audyssey users, how is your LFE doing?

cheers,

Mine is the Denon 3808CI with the larest FW version.

I thought you guys might be interested... "Audyssey", at the support thread I linked here, just said this today:

"All of the Onkyo THX models automatically switch the MultEQ target curve to Audyssey Flat for any THX mode that has Re-EQ applied. In the two Denon products that have THX, you have to switch to the Audyssey Flat curve manually."

For those Denon users that have poorer dialogue, perhaps playing with the different target curves might help out.

Audyssey then later states:

"If you have THX Cinema Mode = OFF and THX Re-EQ = ON then you will have double the roll off in the high frequencies."

A quick update on this, I re-calibrated the Denon AVR-1909 this weekend, and found that Audyssey, for some unknown reason, was setting the level of the center channel too low by 4.5 dB, confirmed with my SPL meter. All other levels were fine, and the distance for the CC was fine as well. I did the calibration 3 times to confirm, and all 3 times it was 4.5dB plus or minus 0.3 dB. I am guessing this is not the only problem, as whatever is wrong is probably compounded in all other aspects of the calibration (i.e. EQ), but my intuition says that there is something terribly wrong with most of the center channel calculations, with the exception of the distance calculation.

Make sure you do at least 6 listening positions in the appropriate matrix. Preferably 8.

This does sound like a bug in the software and a simple one hehe. They always are.

But I would suggest you just use your meter for the sound levels. Or even better your ears. No software will perfectly match your preferences.

The AVR-1909 only has MultiEQ (non-XT) so there is only 6 positions. I set the locations properly for the room in question, AFAIK .

Hi,

I am having similar issues. Have you managed yet to make Audyssey behave correctly/sensibly for your center channel?

 

[TLS Guy]

I must say I have no enthusiasm what ever, for these auto Eq systems. The whole basis of their operation is entirely contrary to my experience. When Audessy was demonstrated to me by its inventor, it made a right hash of the listening material I brought for evaluation.

My advice is as usual to leave those systems off. Good speakers have no need for those sort of programs at all.

 

[BoredSysAdmin]

Well, I agree with TLS - Auto EQ can help only so much, but I can witness than after I re-ran Audyssey auto setup according to instructions here, the result is a huge improvement - no more muffled speakers or lack of present - I wish I wasn't lazy and run REW the old fashioned way T/L graphs and all, but even now I can say (imho) the improvements are self evident.
