Since they seem to be streamlining the nomenclature ...

Ok I get it but since they went from Dolby PL to PL2 to pl2z then to Dolby Surround, I was excited to see the plain looking DOLBY SURROUND and immediately related it to ATMOS.

Well thanks for clarifying FM and Scott, too bad!
----------------------------------------------------------------

I will thus then contribute a pearl of "from the trenches" wisdom as it regards the CP-850 calibration side.

Since CINEMACON I have been interacting with group of Atmos certified installers who calibrate Movie Theaters from a effectiveness of autoeq angle, the consensus seems that the auto calibration feature in the cp-850 is yielding some incidents of mixed result, short story is that for behind the screen channels (and Dolby has received such feedback) the end result for some is a "crunchy sounding" presentation (Jbl-like sounding if you follow my critiques for dubbing stage performance levels, a visit by a dozen avsers to the Lab in LA confirmed room for improvement in this area)this up front while the room surround channels and T speakers the Atmos Auto EQ is excellent sounding smooth and un-distorted- the desired goal. This is not alien to the Fatigue Free B-Chain concept with A-B-C prioritized budget allocations for ATMOS systems where A)Being LCR, B) Screen to Auditorium Transition channels and C)Auditorium Channels.

It could also touch on the Screen EQ subjects addressed in AES 57 conference on IMMERSIVE Sound. Calibrators have obtained variances to use different MANUAL CALIBRATION methods for the main channels, with good results.Thinking out loud DIRAC may have set up a high mark, I am sure DOLBY will perfect this in near future.

Dolby will continue to improve not only the front end where you entre the auditorium metadata into the cp-850, but continue to improve the methods for Auto EQ, they may be working on a 3-D microphone system that not only does what for example a trinnov does, but also some of what it cannot do like keeping perfect track of xyz individual positions in the subwoofer management side, for the CP-850. Perhaps it may even read the room itself. Who knows.

Having not heard yet the calibration of system TRITON in Germany, the first TRINNOV ALTITUDE system using 32 loudspeaker channels in a home Atmos implementation, I am in no position to tell Dolkby buy TRINNOV. .


To this date I am very comfortable with the DIRAC LIVE solution for what it can do for movie theaters, it is the very best solution when you consider that you have a time limit of 2 days to calibrate, when you live in the same place as the theater then by all means use TRINNOV. Because the cp-850 does not have Dirac the solution will have to be one of the SMPTE methods. I believe the Qsys system has great firepower to do that and integrate all signals and connections under one roof digitally.

Here is the overview.


My problem is that I may be ok to use QSC network power dacs (assuming they compare well with the Quested Smart Dante amps)for say the 22 surround and room height speakers (using TRITON ROOM AS EXAMPLE), but for the height channels and width channels may want to use a D'agostino Cinema Standard amps using still something like the benchmark dacs, but then for the LCR I would want to use MOLA MOLA DACS and D'agostino Cinema Standard amps. I would be still using Quested Speakers....

I understand the confusion but it clearly says, 'Dolby Digital' not Dolby Surround.

My Dual 18" LLT subs 120dB down to 10hz

That is why use the forum as a soundboard, it looked as it was spelled simple enough, Hey I think for the amount of misinformation I post compared to the off the chart breakthrough intel I do uncover and share here, seems to me I have earned the right to err? No .

Which I can say when it comes to Laser and how much HDR and now something even more crucial to anyone considering a Large 4k dlp chip Laser projection, we since yesterday confirmed being purview to some secret menu features information 2/3's of the projector manufacturers don't want you to know, that I guarantee you potentially compromises 30% of your image sharpness.

I will not sharing that with you guys, because I admit it's the mother of all competitive advantages and it will shake many vendor boats, but I can brag about it and admonish people against pulling their own "Taras Bulba Ending" in the implementation of a new 4K large chip DLP projector as only one tech has the details in USA and we are partnered in this solution, but anyone considering a dpi or dci 4k machine they are literally playing Russian roulette with their MTF.
