I still run my Sony STR-DA4es. The Cinema modes are interesting in that you can set the surround speakers to virtual speakers (simulated 5 speakers from 2 surround speakers). You have to set the surrounds by position and by height (high or low) in the setup menu.

I assume by 9.1.2 configuration you mean 7.1 + Front Wides + 1 pair of Height/Tops. What we DO know (based on the speaker output chart on pg 287) is that Dolby Surround upmixer, as implemented on the upcoming Denon models, will NOT output to the Front Wide L/R channels:



So if that is your configuration then, yes, Dolby Surround would output a 7.1.2 signal and the Front Wides would be silent.

However, if you are supplying an H2L|H2R speaker pair, then you aren't really running a 9.1.2 configuration right? You actually have 9.1.4 potential speakers. Since we know all thirteen channels can't output simultaneously, and the Denon manual doesn't indicate any way to switch Atmos configs on the fly, my ass-u-mption is that if 4 height/top speakes are present in the speaker config that Dolby Atmos surround mode will default to 7.1.4 output, and the wides would be silent. My presumption is that for Atmos to produce sound output to the front wides, it is mandatory that only 2 top speakers be present in the config, based on the premise that height/top speakers are "preferred" for Atmos output.

The issue (not just the X4100W but the higher models is well) is that it appears they support a MAX of FOUR height/top speakers. The "Front Wide" outputs can't be configured to output a third pair of height speaker signals. The six outputs beyond the standard 7.1ch layout are for four height/top speakers and two front wide speakers.

So while it certainly appears possible to switch between an Atmos output with 4 top speakers and a Neo:X layout with wide + 2 height speakers, it does NOT appear possible to switch between 4 top speakers for Atmos and a SEPARATE pair of front height speakers for Neo:X or PLIIz (i.e. SIX total elevated speakers).

Or, in other words, the only way to switch between Atmos surround and "legacy" surround upmix is if the FIRST pair of elevated speakers are designated as Front Height so they can be "shared" between the modes. Thus it would only work with <Front Height + Top Middle / Top Rear / Rear Height> configs.

IOW will buyers of the new Atmos-ready AVR or pre/pros have a "head start" with Dolby Surround, or have to stay with their legacy upmixers until the firmware upgrade will be ready?

Thanks Sir batpig! (I have had you honored as a knight of the realm of Olde Englande for services to Denon - of the garter order, obviously ).

So I will be good to go, since my intended designation of the ceiling speakers at 42 degrees is Front Height, to be used with Top Middle.

It's not all that important to me TBH as I am expecting Dolby Surround will be better than any legacy upmixer, but as the speakers are there, and it is easier to leave them in place than remove them, I may as well give it a try. I have enough amps lying around here to do it.

Thanks again - you are truly an encyclopedic cornucopia of knowledge of all things Denon.

AIUI, DS will be part of the FW upgrade to Atmos. All Atmos units are mandated to have DS, but I doubt if DS will be available on its own.

That's a very good question. It hasn't been super clear really.

I believe that these devices will not have either full decoded Atmos and the upmixer at start and that both will be included when the updates roll out.

It would be interesting if we got the upmixer to play with beforehand. That doesn't appear to be the case and really it's up to the CE's to decide how to implement that feature.

My guess is that we will have to wait for the upmixer along with decoded Atmos.

Mine too, but we'll learn more @ CEDIA, hopefully, when at least some of us are there .


Slight raining on the parade: With all the enthusiasm about Atmos on AVS (at least among a bubble of hard-core hobbyists), the elephant in the room is Dolby Surround, as the vast majority of content in the near future will be upmixed and not native Atmos. Otherwise, no offense Keith and FM, but those top-firing or ceiling speaker modules aren't going to particularly useful when you get your new AVRs except as "front heights" with Neo:X or Audyssey DSX, maybe (as Dolby PLII is now dead technology in these AVRs, correct?).

From a marketing POV, what would be weird about the firmware for Dolby Surround coming down the pike is that as per FM, Pioneer's already announced the release of the Andrew Jones speakers and Elite AVRs with Atmos capability.

If Dolby Surround isn't ready for the release, you're asking consumers to take a chance that those shiny new Andrew Jones speakers they're buying will "eventually" be ready for prime time over buying conventional non-Atmos capable speakers or keeping existing speakers. If I were planning to buy a Pioneer Atmos-capable AVR (I'm not, for several reasons) I would buy them and wait, and many if not most of the folks here would do the same, but asking Joe Consumer shopping at Magnolia to wait is another thing. I know late August/September is roughly the traditional release schedule for Pioneer Elites, but they might be better off waiting until at least Dolby Surround is ready to keep up the momentum.


At any rate, I personally am not buying anything Atmos-related until after CEDIA.

No offense taken here, Stuart, at all. I have always said that DS will be hugely important for the very reason you mention. I am guessing that it comes with the FW upgrade as it is part of the total package. And it would be bad marketing, IMO, to offer it independently of Atmos anyway - it would allow people to hear a 'less than perfect'. 'sort of' Atmos which could then prejudice their opinion of the real thing when it comes.

I have been hugely impressed at how this is all being marketed, and while there may be other reasons for not releasing DS as a standalone thing, the marketing angle alone is compelling IMO. It would certainly be my advice if I was involved in Dolby's marketing at all.

At any rate, I am 99.99% sure that DS will not be announced independently of Atmos and can't see any good reason why it should. To use DS properly, you need an Atmos speaker configuration and anyone doing that will also want a true Atmos experience from their AVR. IMO.

We can agree to disagree there: the wisdom of having all the Atmos-related firmware downloadable at one time as part of an integrated plan, vs. having Dolby Surround that can use the Atmos-capable speakers ahead of when home Atmos is ready. YMMV, but IMO if Dolby Surround is ready to go, and is "pretty good", I'd like to have it to get a taste of what Atmos might be like with those AJ or Atmos-oriented speakers, set up in the true Atmos speaker configuration.

At any rate, while that's what I'd want ideally as a buyer, you're probably right that it will all be ready and available at the same time.

Remains to be seen whether the height processing and the three-way crossover are only active with Atmos decoding and DS upmixing but not Neo:X or DSX. I would guess/hope that the height processing and crossover are a condition of configuring the receiver for upward-firing speakers, not something that remains on only for Dolby modes. If it is as I hope, then Neo:X can benefit from virtual heights as well.

I may be missing something but I don't think you can use DSX, Neo:X, etc. with the "virtual" Atmos height speakers.

Taking the Denon as an example, you have to specifically designate that you are using "Dolby enabled" speakers when configuring your height speakers layout. And the surround output chart clearly indicates that these speakers only make noise in Dolby Atmos or Dolby Surround modes.

Too bad. There is a version of Neo:X that uses 4 heights in a 7.1.4 configuration that could benefit from virtual height speakers (even if their overhead spots are not in the ideal locations for Neo). Hope it becomes format agnostic in the future.

As I read it, you can use Front Wide (page 168) while NEO:X is selected and (page 209) Wide/Height is set to Default while still be able to play 7.1.4 with 4 Top speakers.
My setup will be: Assign Mode 11.1 with 4 height speakers (Top Front and Top Rear) with Wide Height set to Front Wide and Pre Out set to Top Rear.
This means that 11 speakers are connected to the unit and the Top Rears are connected using a pre amp on Pre Out Height 2.
With this config I ass-u-me that I can play 9.1 with Front Wide from NEO:X and 7.1.4 with Dolby Surround.

Please correct me if I am wrong. This is how I am setup right now and if it cannot be done this way I guess my Front Wides will have to sit until some next gen Denon arrives at the scene.

Again, I think there are two key restrictions that are inviolate:

1. You can only have FOUR elevated speakers (so you can't have four "top" speakers for Atmos and a separate pair of "Front Height" for Neo:X/DSX)
2. If you want to "share" one of those pairs of elevated speakers between Atmos and "legacy" non-Atmos height upmixers, the Height1 output must be designated as FRONT HEIGHT.

It may be academic if your forward pair of elevated speakers is placed within the angular range for BOTH the "Top Front" and "Front Height" assignments, but (based on the chart on pg 287) both DSX and Neo:X can only provide height output to the speaker pair designated as FRONT HEIGHT.

Beyond that, it appears to be free range to connect up to 13 speakers (4 high and 2 wide in addition to the standard 7.1) and switch among Atmos, Dolby Surround, Neo:X and DSX modes. Provided you have sufficient channels of amplification for all 13 speakers.

Anyway... all that being said, it sounds like you want to switch between 9.1 Neo:X (no height speakers, 7.1 + Front Wide) and Atmos in 7.1.4 (four "Top" speakers). This shouldn't be a problem, although again by designating the front pair of elevated speakers as "Front Height" instead of "Top Front" you could switch between 11ch DSX (7.1 + wide + height) and 7.1.4 Atmos. But if you prefer it that way to keep the Atmos config "ideal" with Top Front + Top Rear assignments, it will work.

However, unless I'm wrong it DOES appear you will need FOUR extra channels of external amps. This is based on the paragraph on pg 210:

When one set of pre-amp outputs are used, a maximum 11.1-channel audio can
be output when Dolby Atmos or Dolby Surround are played back. Furthermore,
when two sets of pre-amp outputs are used, a maximum 11.1-channel audio can
be output when Audyssey DSX® or Neo:X are played back in addition to when
Dolby Atmos or Dolby Surround are played back.

That's the problem. You’d have a go and then think a) it's pretty good but I was expecting better or b) it's disappointing, I was expecting better. I just can’t see a single benefit in it from Dolby's POV.

I want to play 7.1.4 = 11Ch in Atmos / Dolby Surround and play 9.1 in NEO:x. In NEO:X only the pair connected to Wide/Height2 speaker terminal and no Height 1 (Top Front) and Pre Out Height 2 (Top Rear). So the above statement is fully correct. I don't need 4 amps because I don't use 11.1 in NEO:X because I don;t have FH's combined with FW's. Page 287 tells me that NEO:X can output sound to FW and FW is connected to terminals Wide/Height2 and assigned as stated above. Again, time will tell but I really think this is going to work.
I cannot go for Atmos FH + Top Middle because that would place my Atmos Front Ceiling pair way to far out. I have 4 ceiling speakers connected and maintained my current Wide speakers and those I would still like to be able to use but without any of the Top speakers obviously because of limitations of the unit.

So yes, 13 speakers connected while using 9 or 11 at a time and when using 11, the Height 2 Pre Out for Top Rear is being used.

That does seem possible when we look at the story behind the "X" in "Neo:X", as excerpted from a small 'puff piece' interview with DTS about Neo:X on TechRadar com (link):

Quote:
"When we showed 11.1, we came up with a concept called 'Neo:X' – where 'X' could be any number within reason. 'X' for CES was 11.

[11.1] was what we showed. It could be 11, it could be 9, it could be 13, it could be 366. The Master Audio algorithm is very expandable."

That was sort of the claim to fame of their algorithm that it would be expandable to essentially an unlimited amount of speakers. Hence the moniker Neo:X.

Will interesting to see what they bring to the table.

Hey guys,
Any opinions on Triad in-ceilings (silver or gold) for Atmos? Also, any idea on their approx cost?

There's little chance but I wonder if older (2-3 year) AVR's will see the new Dolby Surround firmware update? That would be nice.

I think I can, I think I can
