Author Topic: Cinelister for Doremi Server Anders Nordentoft-Madsen Film Handler Posts: 57 From: Valby, Denmark Registered: Aug 2005 posted 10-30-2017 08:17 AM                        Speaking for someone that now has 5 diffent new sites running qsys on multiple screen, I can confidently say that its been just a stable as any AP20 setup. The need to change something in the design "live" is not something we have ever had the need to do, mind you most of the screens are "just" 6 screen "mall" multiplexes. We also have Atmos screens running Qsys (with a Cp850) and they have there own core, partly because of number of channel and partly because of the atmos recievers in the qsys design; for atmos the cp850 need to be synced to the core so mulitple atmos designs on one core (or 7.1/5.1) is not possble. Last two sites have been using the core110f, so 6 screens on one core is possible due to the increassed number o f channels on 110f vs i500. Running this in redundand mode with at extra core and network redundancy also has proven to very stable, I fact I have one had one screen swaping to redundand core over the last 2 years and that was due to a local screen swicth crashing. Last piece of the puzzle is the new cinema i/o frame, giving us HDMI, AES, and HI (something we needed a extra box for) all in one box.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 10-31-2017 01:42 PM                     It's great to know the QSYS solution is stable. What is the financial advantage of the whole system? Considering you have to install DPA-Q amps, switches, network runs compared to - say - an AP20 or equivalent?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

BUT you have to add in the cost of the core. The Core plus IO box is in the same ballpark of an AP20. However since a core can handle multiple screens, you are ahead of the game on the second screen. Likewise, if you are using dual redundant cores, then you are ahead by the 3rd screen (just using rough numbers).  |  IP: Logged Anders Nordentoft-Madsen Film Handler Posts: 57 From: Valby, Denmark Registered: Aug 2005 posted 11-01-2017 05:51 AM                        I believe a Core 110f is about 1/3 cheaper than an AP20....  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 11-02-2017 04:54 PM                     So for a 10plex you're saving like 8000 - 800 per screen?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-02-2017 05:02 PM                     Probably considerably more than that once you factor in running short runs of speaker cable to the stage because the amp(s) can reside near the speakers. The flexibility also goes way up. Some things come along for the ride too like if you have Non-Sync music, distribution is built in. If you use QSC speakers, you get intrinsic correction built in so tuning should go faster (saving money). But even on the hardware, compared to an AP20 set up, the more screens you put in the system, closer you get to about $2,000 cheaper/screen on processors alone. There are other variables that will vary by complex (how one handles the user interface, for example)  |  IP: Logged
