"Official" Audyssey thread (FAQ in post #1) - Page 1000

In a word, YES. IMHO room correction EQ is a significant advance for both HT and listening to music. Audyssey adds little cost, yet provides quite an increase in SQ and is thus an excellent value. The minimum I would recommend would be MultEQ, as it capably handles all channels including the sub. Depending on your listening interests, equipment and budget there are several even more sophisticated Audyssey options in higher-level AVR's.

In my experience, DV can help considerably, but this is a matter of personal taste and specific source. As you know, DV is adjustable,and the middle setting (Evening) provides a popular choice in amount of compression. I often use that myself for films laden with serious dialog and little action. I do find it annoying when directors/actors/sound guys/remixers, whoever, occasionally get the soundtrack so wrong that I still end up cranking it up and rewinding a section of dialog.

There is of course a trade off and I usually leave it off entirely to enjoy the full exciting sound effects on action films. I personally use it frequently for TV viewing, to tame commercials. I never use it for music.

I'm not familiar with the NAD, but the description says "An optional kit is available to customize the Audyssey set up of the M15HD. This is not a necessary item for the average consumer but a more advanced owner can use this kit to tune their room set-up in additional ways."

Those of us who have MultEQ XT in our installer-ready pre/pro's can run the basic 8-position Audyssey calibration without purchasing the optional Pro installer kit. And those of us who have wanted the extra features of the kit have paid $US 550 plus an additional $US 150 for the license.

Can you not run the basic Audyssey calibration with the NAD without purchasing the kit?

I was not familiar with the NAD, either, but it appears from scanning the OM that, as the OP described, the Audyssey technology is indeed locked inside, awaiting, as they suggest, a Pro installer. Interesting decision on NAD's part.

Wow, my view shows page 1000!!

Any Aussie Pro Kit owners here near Jezza56 in Adelaide?

Hi. If I am going to run an Audyssey setup test, should I bring my vol. knob up to "0" on the dial on my AVR before the start of my tests or does it really matter? Also, if after the test runs, should all your speakers be outputting sound at 75db @ 1 meter when the vol. knob is set to "0"?

Thanks,
Bob.

Does not matter. All control settings are ignored.

The new Denon AVR-4311CI is reported to incorporate a new Audyssey technology, Sub EQ HT, in addition to MultEQ XT 32 & DSX. Is this correct? If so, is it an integrated version of the standalone Sub Equalizer, which can separately EQ two subs? The "enhanced audio playback quality in any listening environment" quote is quite vague.

Thanks pepar.

Bob.

Good question. I googled "Sub EQ HT" and your post came up along with two instances of the press release you linked to. I have read it before, but never took notice to Sub EQ HT. I know what "Sub EQ" is, but haven't a clue about the "HT" on the end.

Chris, can you tell us anything?

Jeff

Hi Larry,

The curves you posted are just a measurement of the static Dynamic EQ response. What's missing is the most important part: the Dynamic part! The adjustment being applied depends on two factors: (1) the volume control setting (those are the curves in the picture) and (2) a real time estimation of the content loudness in each channel. That last part is the tricky one to get right. Think of it this way: content comes along and it varies between soft and louder parts as its playing. Then you turn the volume down. The softer parts will need different adjustment than the louder parts. The trick is to do this with the right time constants so you don't have the listener go crazy. The other trick is to make sure you are not messing the spatial balance of the mix (in surround). And finally, you have to come up with the right way to measure loudness in real time.

So, unfortunately, simply adding a little bass boost shelf will only get you a small part of the puzzle...

One word: "two subs".

Hi Bob. Pepar already answered your first question. As regards the second one, the outputting sound should be 75 dB:

1. ...but not @ 1 meter from each speaker, but at the MLP (Main Listening Position),
2. ...provided the input signal is -30 dB FS band limited pink noise 500 Hz - 2 kHz. This is usually the test signal AVRs output.

Thanks for that info, mogorf. Appreciate it.

Bob.

them's two words!

sounds like great news for those people clamoring for dual, independent sub calibration. gonna be a lot of unhappy 4810 owners if the 4311 has MultEQ XT 32, dual sub calibration, and 11ch pre-outs!

That's two words

But, acting as "one"

What interests me is the statement at the end of the article, "The AVR-4311CI is available for order now in select stores."

I have not been able to find any references to where it might be available for sale, nor is there any mention of it on the official Denon site. How reliable is http://www.bigpicturebigsound.com? Has anyone actually seen it for sale?

That "available now" is part of the press release, not content from BigPictureBigSound.

If you google "AVR-4311CI" and "cart" you will get a LOT of hits with most of them saying "coming soon."

What's the low frequency correction limit of MultEQ XT on the SEQ, 10Hz?

Kal, do you think you will be reviewing any MultEQ XT32/Sub EQ HT products?

Chris, is it likely that Denon will be showing the AVR-4311CI at CEDIA?

It is likely.


Not Chris but I think so.

It does seem like a given with "C-I" and "C-E-D-I .. "

I have been listening to movies of late and i have found that my centre channel speaker is down in volume some, so i went into my speaker channel level and i noticed it is right up there. What could that be,does this have anything to do with the audyssey set up.Thanks Grassy

Not anything with Audyssey. Could you have a blown driver?

I had a feeling it could be something like that. I will get it checked. BTW i like your home theatre project, it was very interesting, especially the way you did the bass traps. The electric knife for cutting that stuff is a top idea.

If you play the speaker level test signal and move it across the front three speakers, you should hear a very noticeable timbre difference on the center channel.

Jeff

Thats exactly what i did. I have a tech on his way now to test the speaker. When i did the test i noticed a huge difference in sound compared to the left and right mains. I noiced when watching a movie the centre channel seems to be in the background and not up front as a mate of mine also noticed it. I thought it might of been my hearing(old age)hehe. I noticed also when i did a audessy test it came up with a "centre caution phase error".I will know for sure in about a hour from now.
