Author Topic: Cinemark Installing Auro Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 09-27-2015 07:58 AM                     The 'LFE experience' will be be dictated by the soundtrack and the auditorium. I don't think that bass management has anything to do with that. Rear subs are there to further extend surrounds' low frequencies - which, IMHO, I'm not sure it's something so desperately needed, but it doesn't hurt.  |  IP: Logged Jonathan Goeldner Phenomenal Film Handler Posts: 1360 From: Washington, District of Columbia Registered: Jun 2008 posted 09-27-2015 11:40 AM                     I was sort of surprised and miffed that Cinemark Fairfax Corner 14 - while at one point I thought had two Auro systems - this wasn't the case only auditorium #6 - not #9 (went to see 'Everest' last Monday - took one look at the speaker setup, no height channels or ceiling speakers - huh? drove over to the Egyptian instead). From what I could understand auditorium #9 is still in the process of getting said system. At this point, they could either upgrade to Auro 13.1 or Auro's object based system: AuroMax. Question: since Auro 13.1 is essentially 7.1 with heights why hasn't there been more of a push to mix with the back rear surrounds in the first place? 'Everest' seemed lacking without the back wall of sound.  |  IP: Logged Bobby Henderson "Ask me about Trajan."

If you visit the Auro web site the only place you see 13.1 mentioned is in the consumer electronics space. I really wonder if theatrical Auro installations are just stuck with 11.1. With the way d-cinema is set up there is no "fold-down" capability between 7.1 and 5.1 LPCM audio tracks. The DCP literally has to contain both, which seems pretty backward considering the old (and dead) SDDS format could fold-down from 7.1 to 5.1 and even to 4.1 or 4.0 if necessary. Maybe it's the difference in playing a sound format with packeted data rather than something with "raw" linear data. You can only do so much with LPCM. Auro is half bit-reduced LPCM (the base 5.1 layer) and half lossless audio (the height layers). Maybe it's a technical hassle to get a 7.1 LPCM base layer incorporated and make it to where it can fold down to 5.1. At any rate, Auro 11.1 needs to go bye bye and make room for AuroMax/DTS MDA. quote: Aron Toplitsky So which of the two formats have better bass management and provide a better LFE experience? Dolby Atmos. But that's only if the theater bothers installing the surround sub bass enclosures. Not all Atmos-equipped theaters have it. quote: Aron Toplitsky Also, does the Auro 11.1 system place subs in the rear like an Atmos set up? No. quote: Marco Giustini The 'LFE experience' will be be dictated by the soundtrack and the auditorium. I don't think that bass management has anything to do with that. So many movie theaters cheap out with their surround speakers. You'll have a huge room and what do they do? Install these little tiny speakers on the wall. The approach is a little like the old Bose Acoustomass setup with those itty bitty cube speakers and a bass box trying to make up for the difference. Very few theaters anywhere install surround speakers with any kind of full range response. Timbre matching is a pretty big deal. It's a big waste to have a thunderous 4-way system behind the screen, along with a cluster of sub bass enclosures yet have dinky, tinny speakers in the surrounds. If a sound pans from the screen into the surrounds it creates something like a Doppler effect in terms of EQ. It's just wrong. A pair of surround sub bass enclosures really isn't enough either, but it is better than nothing.  |  IP: Logged Jonathan Goeldner Phenomenal Film Handler Posts: 1360 From: Washington, District of Columbia Registered: Jun 2008 posted 09-27-2015 06:31 PM                     the 13.1 system is mentioned here on the companies website (systems subsection): http://www.auro-3d.com/system/ HOME THEATER (SMALL ROOMS) - AURO 9.1 - AURO 10.1 (+ TOP CEILING / VOG) CINEMA (LARGE ROOMS) - AURO 11.1 (+ FRONT HEIGHT CENTER) - AURO 13.1 (+ LEFT REAR SURROUND + RIGHT REAR SURROUND) the latest issue of Widescreen Review notes that 13.1 and AuroMax are the latest incarnations of the systems that are implementing more speakers into the overall design and integration of multiple sound sources.  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 09-27-2015 07:41 PM                     The big question is, of those movies that are supporting Auro, do they include separate Auro 11.1, Auro 13.1 and AuroMax mixes on the DCP? In the case of AuroMax I suppose that would be DTS MDA actually. A theater could install an Auro 13.1 system, but if the DCP only has an Auro 11.1 track then the theater's system would be stuck playing the track in 11.1.  |  IP: Logged Jonathan Goeldner Phenomenal Film Handler Posts: 1360 From: Washington, District of Columbia Registered: Jun 2008 posted 09-27-2015 08:56 PM                     couldn't a master 13.1 mix be made, and then the theaters that are 11.1 - the processor's decode what the theater's speaker/system setup is, if the theater isn't 13.1 - it doesn't decode the speakers that aren't there? Like what home theater processors do, if you don't have Atmos, 7.1 or such, and you only have 5.1 you get only the folddown mix?  |  IP: Logged Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 09-27-2015 09:49 PM                     quote: Jonathan Goeldner couldn't a master 13.1 mix be made, and then the theaters that are 11.1 - the processor's decode what the theater's speaker/system setup is, if the theater isn't 13.1 - it doesn't decode the speakers that aren't there? It would have to mix down to 11.1. You don't want to just throw away the sounds from the back left and back right. I'm sure the hardware has the power to handle this. Who knows if they will write the software to do it.  |  IP: Logged Aron Toplitsky Expert Film Handler Posts: 113 From: Gardena, CA, USA Registered: May 2012 posted 09-30-2015 01:28 AM                     I've been to quite a few Atmos equipped theaters in the LA area and like I've posted on this site before, one that seems to do it really well and probably better than all the others, is the (not referring to their IMAX) TCL Chinese Theater Six - screen # 1. Of course it depends on the movie and it's mix, but the two that really stood out were Godzilla and Mad Max. Not only were the surrounds very active, but the LFE was absolutely pulse pounding and very aggressive! They must play their films as reference level. It's quite loud yes, but I've never walked out of there with a headache. It's a very powerful system with no distortion whatsoever. I highly recommend checking it out if anyone lives or visits the LA area. Would anyone know what system AMC Prime theaters are using? Auro or Atmos?  |  IP: Logged Bobby Henderson "Ask me about Trajan."

They do have a 9-plex in Dallas recently converted to Dolby Cinema that has never shown up on Dolby's Atmos installations map. That one screen makes me wonder. I think AMC has one lone Auro installation at a theater in Miami.  |  IP: Logged Aron Toplitsky Expert Film Handler Posts: 113 From: Gardena, CA, USA Registered: May 2012 posted 10-01-2015 01:34 AM                     Thanks for the info Bobby. I find it interesting how the AMC Dolby Cinema showings of The Martian are not indicating 3D presentations.  |  IP: Logged
