Multiplex setup - Audio - what , how etc

[Bloom@83]

Friends

After almost 9 months tentatively ventured out to watch Nolan’s Tenet in multiplex (Cinemax ) Kolkata.
These 9 months were also a period in which I had spent the longest time with my modest stereo and HT setup (mainly playing PS4) , no thanks to the pandemic.

Thus , watching Tenet in the theatres raised questions in my mind completely unrelated to Nolan’s high concept time inversion and reverse entropy thingamajiggs, questions I never bothered much about earlier. Namely they were :

- What kind of digital projection systems is being used in these multiplexes ? How do they achieve almost uniform brightness throughout such a wide viewing angle ?

- What and how many speakers are being used ? I could see no ceiling speakers , so isn’t Atmos used in Multiplex (why am I paying money for then ? )

- What codecs are used here ? Is it something proprietary to multiplexes or the normal consumer ones like DTS X or DD + ( or their latest avatars )?

- Lastly , and crucially , what kind of amplification is being used ? How much power are we talking about here ?

Any kind soul knowledgeable in this matter can care to enlighten without too much technical jargon , I would be most obliged to.

Would be glad to know the answers of the op's questions as I am also eager to know about the audio out put in a multiplex.

Nice. Although I was more interested in the audio setup.

Dolby processor - cp850
Amplifiers like crown DSi or QSC DCA.
Speakers like - qsc sc 424
Subwoofers like QSC sb 7218
Power depends on the size of the theatre.
However these speakers are very efficient.

Apart from the audio equipments mentioned here, isn't it the specially(acoustically) treated room of multiplexes that wins our hearts?

Treated Room as others said and powerful amps which can touch 2 ohm loads easily. With more power , micro details are output with precision. Finally a Lossless original Master Movie print as source.

For me, one of the best experiences I had was in JAM Ghaziabad and they had installation from Martin Audio.
