Author Topic: New Projector Pavel Volf Film Handler Posts: 3 From: Kladno, Czech Republic Registered: Jan 2017 posted 01-24-2017 02:37 AM                     Dear Sir/Madam, we would like to install a new projector to our cinema. We are currently deciding between Barco DP4k-23BLP and SONY SRX-RS15DS. The projecting distance is 21 meters from the screen. The screen size is 14,5m x 6,5 m. I would be very grateful if you could offer me some advice on which one is more suitable for our cinema. Thank you very much, Pavel Volf  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-24-2017 07:27 AM                     Hi Pavel, if you are considering the 515DS, you are obviously aiming for 3D as well. The Barco 23B is underrated for 3D at this screen size. You won't find many Sony friends on this specific forum. Maybe you should spend the time for a trip from Kladno to Cinecittà at Nürnberg/Germany. They have many 515DS systems installed there, some within ATMOS installations. They will certainly welcome you there and share their experience. They even have a quad-head DS in their largest auditorium. - Carsten  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Sony dual projector is of course more equipment to service to maintain image quality and contrast. Your local service vendor is a very important factor in your evaluation of what you buy and what to deal with during the operating life of the system.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

All other factors being equal, I'd choose Barco over Sony with barely a nanosecond's thought, but the other factors (besides brand reputation) are sometimes not equal. I once had a FIAT car, which have a pretty terrible reputation, especially for reliability. However, there was an independent garage that specialized in Italian cars just around the corner from me, and for that reason I kept it a lot longer than I would have done otherwise.  |  IP: Logged Mike Schulz Expert Film Handler Posts: 122 From: Los Angeles, CA Registered: May 2007 posted 01-24-2017 10:49 AM                     quote: Leo Enticknap I once had a FIAT car, which have a pretty terrible reputation, especially for reliability. https://youtu.be/3AJCdmW33fM  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-24-2017 11:41 AM                     A Sony Dual Stack would also project the 3D simultaneously: no flashing, no dark time. That will make 3D much more comfortable and - if not mistaken - will also give a better light efficiency over any polarised 3D system on a DLP machine. Downside: Sony must be polarised, hence the awful silver screen. What Carsten said: get familiar with the systems, learn the potentials and make sure you end up with decent service personnel, that will make the difference.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-24-2017 12:17 PM                     Sony.....  |  IP: Logged Pavel Volf Film Handler Posts: 3 From: Kladno, Czech Republic Registered: Jan 2017 posted 01-24-2017 01:26 PM                     Thanks everybody for relevant comments I was thinking the same. We have already had one Barco projector and we were very satisfied with its service. That is why I decided for Barco. However, Sony looks really good, too.  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 01-24-2017 05:15 PM                        The Sony 515 has some nice improvements compared to the previous models. There are rumors they will show something new at Cinemacon in March. Laser?  |  IP: Logged Anders Nordentoft-Madsen Film Handler Posts: 57 From: Valby, Denmark Registered: Aug 2005 posted 01-25-2017 06:47 AM                        Please note that he says Barco BLP (so laser) by that account is should be good for 3D as well.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-25-2017 07:55 AM                     It certainly is good for 3D, but still has a peak luminance of only 24.000 lumens, decaying over time. And as a BLP, it doesn't benefit from color separation efficiency as modulated 3P or 6P laser systems do. So that leaves options at standard switched polarizing or shutter 3D systems, with their still mediocre light efficiency. Pavel - is this a single screen cinema, or do you operate other systems there as well? Do you use a TMS? What 3D system/screen type are you using now? - Carsten  |  IP: Logged Pavel Volf Film Handler Posts: 3 From: Kladno, Czech Republic Registered: Jan 2017 posted 01-25-2017 01:10 PM                     It is a one screen cinema for now but we would like to start projecting on a smaller screen soon with the Barco DP2k-32B projector we already own. We will also change the screen for a better one - we've been using Dolby system. Laser projector is also good for decreasing our costs. Now we have a xenon lamp 6,5 KW with service life 500 hours. Laser should have 30000 hours.

One thing to consider is to retrofit the Barco you already have, but for now the 32B can't be retrofitted, but maybe in the future.  |  IP: Logged
