quote: Scott Norwood
They really built a processor with no analog input? That is going to bite anyone who does festival screenings or special events in a venue with this type of processor. I'm guessing that there is no 35mm film support, either?
It does have a stereo non-sync input. No 35mm support either, but that was somehow to be expected.
quote: Harold Hallikainen
I believe ATMOS Connect is BLU link, so that support was probably brought over from the CP850. It's possible to license FPGA code that accepts I2S or I8S audio and drops it onto BLU link.
Yes, Atmos Connect is BLU link, or at least it's based on it (I don't know if they've extended it with their own proprietary stuff).
There are some pretty expensive processors out there that can get you from analog to BLU link right now. Still, more doable than to build your own interfaces. I guess since even the ARM processor on a Raspberry Pi could do most of the legwork needed in software, there is not even a need for an FPGA in there. ![[Wink]](wink.gif) My biggest problem with BLU Link is that it's yet another proprietary protocol, with no readily available specifications and most likely quite some licensing costs.
quote: Steve Guttag
But, if it were me, there would have been the analog multi-channel input and it would have been pretty complete product for what it could be.
I guess that's something almost everybody agrees upon. But that's why I went looking for a decent alternative to get those channels into the machine.
I don't know about licensing costs for Dolby, but it looks like they don't like to pay for any licensing where possible. They also skimped on the DTS licenses.
But I'd say that such a licensing powerhouse like Dolby, would probably have sufficient bargaining power to get the licenses for their devices rather cheap. Also, we're not really talking about consumer-grade equipment here, were every dollar you save can make the difference between profit or loss.
AES67 might even be a better solution than Dante or BLU Link, since it's an entirely open standard, but right now, the amount of products available for it are still a bit lagging and for whatever reason often even more expensive than Dante products...

Again, I don't think the missing DTS decoding is a real issue anymore, as long as it DOES have HDMI LPCM multichannel audio capability. Many, if not most of todays Bluray-Players and other devices can decode all Dolby and DTS codecs to LPCM. This is typically done by autonegotiation between source and sink (No DTS-HD Master decode->Switch to Multichannel LPCM).
That was no option for the CP750, as it only had SPDIF/TOSLINK connectivity which can not convey multichannel LPCM.
If the CP950 comes at the same price as the CP750, and includes an upgrade path to ATMOS, I guess it's not such a bad choice, given that it offers internal crossovers, which saves quite a bit of additional gear and setup cost for external crossovers, monitor, etc..

Many will probably use the internal crossovers of the CP950, so, the speaker configuration then is specific to the 950. We just have that issue on a german forum (connecting a CP500 for film), and, you would either go full passive, or the filmsound processor would need to do the same active crossover to enable this (e.g. CP500/650). You would also need to calibrate/EQ both systems separately. Unless you use external active crossovers. There are certainly multiple ways to solve the issue, but, none is cheap or easy or elegant.
I think this will come up quite often now that the CP950 hits the streets. Quite a few sites will probably try to add a pre-existing CP65/DA20, CP500 or CP650 for filmsound to a CP950. I can see the rollyes of the Dolby sales people, and the reluctant nodding of their engineers when they hear 'And what about our film sound?'

- Booth monitor and crossover built in
- Web UI that is very similar to that of the CP850 (so only a small learning curve for installation techs, and no separate PC app needed for tuning, etc.)
- Can be made Atmos-capable by adding a card
- Has HDMI 2.0 with HDCP 2.2 pass-through for alternative content audio
- Same ballpark price as the CP750
If the CP950 can be made Atmos-capable simply by adding a card, how does the price of adding that card to a CP950 compare to the price of a CP850 with Atmos capability out of the box?
I think Dolby Atmos has been rolling out to movie theaters at a very slow pace in part because of the really high cost of the CP850. Dolby slashed a few grand off the price a couple or so years after the CP850 was first released, but it was still really expensive. Combined with other factors (like needing to buy a shit-ton more amplifiers) Atmos turned into a very cost prohibitive equation for most theaters.
If the CP950 with Atmos capability and the new Dolby multichannel amplifiers can dramatically lower costs and make installation easier that could lead to a lot more theaters installing Atmos.

Just about any Blu-ray player will feature basic internal DTS decoding for output to a non-surround playback device, such as the built-in speakers of a HDTV set. It's similar to how Dolby Digital was handled in many DVD players. Not all Blu-ray players are capable of 5.1/7.1 LPCM output of decoded DTS-HD Master Audio streams. It's an important point to consider since DTS-HD remains the dominant audio format on Blu-ray. But that's only if the given theater plays any alternative content off Blu-ray disc.
