From the article:

"Dolby Laboratories announced the deal on Wednesday, which includes the Dolby Atmos Cinema Processor CP850 and the Dolby Digital Cinema Processor CP750."

It would be interesting to know how many of each.

There's probably no formal statement regarding how many of which, but I think there are press releases covering the number of ATMOS screens Wanda want's to install, so you could calculate an estimate.

That said - the Dolby Cinema at Eindhoven has/had a full redundant (second) CP850 installed in it's booth, and I don't know if that is common strategy for Dolby Cinema ;-)

If I recall correctly Dolby is now selling two different versions of the CP850, one with full Atmos capability and another significantly less expensive version that can be upgraded later with Atmos functions. I guess that's a way to encourage theater operators to move up from the CP750.

If they are doing this, I assume it is just some kind of software upgrade. Electronics are so integrated now that I wouldn't think there is an "Atmos Card" in the CP850 as part of the design.

It would be a similar strategy to way back when they sold the CP-500 with or without Dolby Digital. Only then, there were actual physical boards missing.

The CP850 arives in a ridiculously large carton (looks like a repurposed DSS200 box, maybe they will use something smaller when those run out) marked "CP850 BASE".
It will not load an Atmos room design (with ceiling speakers) or play Atmos sound.
The CAT1600/1601 audio hardware is all in there though, and I'm not sure if you can even buy one without generating the Atmos license activation code.
The CP850 decodes the Atmos CPL audio, not your server so it has a secure media block like the server (the CAT1600). That requires a different security manager version for servers (not DCI compliant so far) and a second KDM - at least for some server models.
To activate Atmos you find the activation codes that were emailed to whatever email address the purchase order came from (Dolby support is used to having those get lost by purchasing departments and will help you get them). Then you plug that code into the Dolby activation portal with your CP850 and CAT1600 serial numbers for it to spit out an "entitlement" (.dae) file. Then you open the CP850 web gui and upload the entitlement... voila! Atmos!
The CP850 is nicely built like the DSS servers were. The (much smaller/lighter than a DSS200) chassis is quite full. I haven't poked deep to see the system board(s), the audio boards fill the "top layer" once the chassis cover is off. Way more complex than the single board CP750.

Pretty darn big news on the Wanda rollout!

Too bad it isn't doing crap over here.

Wonder what the cost difference is compared to Dolby Digital adjusted for inflation.

This thread opened one year ago today.

The cost could only be compared to Auro or DTS-X. Regardless of the processor cost, more money gets spent on speakers, amps, wire, and tech time hooking it all up: Atmos means a considerable increase in all of these costs compared to a 5.1 or 7.1 system.
The speaker and amp selection and count depends on the room size and shape - Dolby has to give their blessing that the design meets their specs.
Once configured, you upload the room design into the CP850 so it knows where the speakers are. On playback, it maps the ATMOS audio objects into the room, sending audio object sound to whatever speakers will best locate that sound where the post production sound mixer wanted it.

I wonder how much Atmos-equipped theaters are having to pay for the Dolby Connect service? Is that an ongoing service cost via subscription or is it just paid up front in a big lump sum fee?

I noticed this afternoon that there was a FANTASOUND logo to the right of the DOLBY ATMOS logo on the end credits of "The Jungle Book." I found an article about the movie from Forbes (April 7). Here is an excerpt:

Another fascinating moment during the press conference came when Favreau talked about his love of the film Fantasia, and how Walt Disney's desire to put the audience in the middle of the orchestra sound led to installing multiple speakers all around theaters in a few select locations. That concept and the impact it had on Favreau personally led to a specific decision in how to approach The Jungle Book. Favreau explained, “I remember when I was talking to my sound people and to my composer John Debney, I said, ‘Wouldn’t it be cool to explore what Fantasound [as the original Disney stereophonic sound was named] would be now?”
The Jungle Book credits actually refer to the film as using Fantasound, because it turns out the filmmaker’s desire to bring back the concept was far more doable than he might’ve first imagined it would be. “The sound engineer said, ‘Well, [Dolby] Atmos sound has that many speakers all around the theater. You use it for sound effects, there’s no reason you couldn’t use it for music,’ ” Favreau said. “ [John Demney is] a Disney guy. He grew up on the Disney lot. He knew Walt, and he hung out with the [songwriting team] Sherman Brothers when he was a little kid. So he breathes Disney, he knows the culture, and he really leapt at the opportunity. So when we were mic’ing the orchestra, we isolated instruments when we could. And in the sound mix, Lora Hirschberg — who’s our music mixer — we tasked her in the Atmos mix with creating a Fantasound mix.”
So in Dolby Atmos, Favreau adds, “[Y]ou will feel there are instruments that move around the theater, especially isolated instruments, like the flute as Mowgli’s running. So if you see it in a Dolby Cinema, you’ll experience a version of what we were trying to channel, which was Walt’s vision for this.”

I noticed that a couple of weeks ago during some pre-opening sreenings.

Thanks for the 'backstory' on that!

I found the The "Filmed in Downtown Los Angeles" credit somewhat amusing too.
Don't movie studios bother to build sets anymore? Every production still photo
I've seen from this film shows the child actor working in front of a green screen
surrounded by minimal props & a wholebuncha ping-pong balls on sticks.

At least the 'original' (1942) version of this film had real locations (even if they
might have been on a backlot) and real wild animals instead of artificially
generated creatures. (and 'real' Technicolor too! )

200,000 watts? I'd be curious what scale that's measured on.
It's 200,000 watts peak-to-peak. So that's 100,000 watts peak. Which is 70,000 watts RMS. But that's at 10% distortion. At 1% distortion it's 10,000 watts. But that's at 60Hz to 8KHz. At 20-20KHz at .5% distortion it's 5000 watts. But that's with each channel driven individually. With all channels driven, it's 3000 watts. But there's 64 channels. So it's 46.875 watts per channel.

Aside from the "Fantasound" nonsense, I can say The Jungle Book does have a pretty good Dolby Atmos mix. I didn't really notice lots of individual instruments of the score being positioned in different areas of the theater, but the score was often shifted into the surrounds. One of the best Atmos-specific surround effects in the movie is the dialog from the snake, Kaa (voiced by Scarlett Johansson). Her voice tracks around the room and over the ceiling as she hypnotizes Mowgli.

the 12-channel IMAX-laser sound mix is equally impressive and very immersive.
