Yep, Bryan is right, it seems the big issue is available processing power, and if a receiver wasn't designed specifically for Atmos then it isn't compatible. After doing some more reading around here, I also remembered that is the reason many of the new Onkyo receivers have dropped Audyssey. Too much processing between the two means they'd need more expensive hardware to use both.
Denon AVRX4100 and AVRX5200 have Atmos and Audyssey MultEQ XT32 with SubEQ HD. Shipping now, ahead of schedule.

Onkyo clearly was worried about price point and in doing so have created the entry-level Atmos AVRs, where Denon has created more of the upper end. Onkyo's in-house auto cal is pretty much laughable, but at least there's something.

Each additional channel means another Audyssey filter, in addition to the Atmos processing needed to create that channel. That's a lot of overhead!

It seems like a funny time to be short on processing power, given that we should have it in abundance. What happened to Moore's Law!?
Moore's Law still works just fine, but products have to also be priced to sell. In Moore's 18 months there'll no doubt be lower cost Atmos/Audyssey AVRs. We're just at the beginning of the Moore cycle on this one.

Re: Dolby Atmos is coming Home!

The Denon 5200 started shipping last month (I played with one that had been delivered by Amazon in mid-August).

Meanwhile, Dolby announced the first Blu-ray in Atmos (due by end of month).

Re: Dolby Atmos is coming Home!

By looking at the dolby atmos 7.1.2 setup diagrams it appears to basically be a 9.1 setup using heights.
Until they have developed equipment to handle unlimited speakers i personally don't see this as anything more than a NEO or DSX experience. Frankly its backwards as I can now do 11.2 with wides and thus increase my front soundstage.

If your starting out new it may be the way to go.....

The Denon 5200 can do 7.1.4 with a two-channel outboard amp. That would be the typical 7.1 layout with four overhead speakers.

Sorry about that, I must not have read far enough into the article to see that it did 4 overhead speakers.
Even so....I feel its just another option to whats already out there. Sound coming from ceiling instead of front height and front wide. Don't get me wrong great things don't come unless companies try new things. I hope down the road they open up some great new opportunities with this technology. I'll be watching with anticipation. Much like I am for 4K projectors to reach the $3K price range, that is if 8K projectors don't get here first.

Re: Dolby Atmos is coming Home!

In my opinion, 7.1.4 would be the very least that I would be interested in. And that's if it can accomodate 2 or more subs. Which is what most serious theaters have or will have. Would not buy in to is without multiple subs.

The Denon 5200 and 4100 will have dual sub outs with Audyssey SubEQ and XT32. No problem there. The 5200 has the ability to do 11 channels of processing simultaneously, and the 4100 can do 9 channels.

I agree that 7.1.4 is the minimum. I would prefer the ability to add a set of wides and maybe a third set of overheads. So 9.1.6. I can't see much benefit to going beyond that in hardly any home setup.

A 9.1.2 Atmos setup still makes use of front wides along with a pair of overhead speakers. I agree though, 9.1.4 or 9.1.6 would be cool but I can't imagine anything more than that being a drastic improvement in the average home cinema. I am currently wired for a typical 11.2 setup. I will probably wire for 6 Atmos speakers so I can make use of x.x.2 or x.x.4 Atmos configurations. And if x.x.6 becomes an option someday I'll be set.

What I want to know is. With Atmos "enabled" speakers, why don't the atmos modules articulate separately. With the importance on setting up L/R speakers, and the plethora of living room sizes, shapes, ceiling heights and seating distances, it seems like this would matter. Especially with the "object based" part, and bouncing the sound off the ceiling, it just seems like another way to fail the setup.

Atmos is a very different experience from Neo and DSX, both of which artificaially create the height and width content based on proprietary algorithms. There's no real regard for what the original mixer intended. The effects might be nice, even believable (especially DSX), but Atmos is very different. It directs each sound "object", or element to the location the mixer intended, with scaling to put it there based on whatever speaker count you have. That means if a sound is supposed to be high and to the right, it always goes there. DSX and NEO, there's no telling where it's supposed to be, as there's no location information at all, it's just a guess, an extraction if you will.

To your credit, you've taken the plunge already, and 11.2 is admirable! The nice thing for folks like you is, during setup you tell Atmos what speakers you have, including your current 11.2, and it uses them where they are. If at a later date you'd like to add more, you can do that too. The limitation will be with the number of outputs available on an AVR, either powered or preamp outs. The Trinnov Altitude 32 actually covers the complete channel count for Atmos at home. AVRs may take a little longer to get there because a 32 speaker setup won't account for a lot of sales volume.

Remember, Atmos is directionally correct at all times, DSX positioning is based on an algorithm applied to material that contains no discrete directional information.

DSX is great, no question, but Atmos has their own "decoder" which will "light up" all your speakers, even with non-Atmos tracks.

BTW, the X5200 will do 11.2, with 11 powerd speaker outs. It will do 13.2 if you use the pre-outs.
