Author Topic: Options for running intermission Music Stephen Frazza Expert Film Handler Posts: 161 From: Nutley, NJ, USA Registered: Mar 2004 posted 08-28-2012 11:29 AM                        We are about to wire our theater so we can use the Dolby Show Library. We have 6 spread out booths and when we run the cable for the library I want to also run cable so we can run all of our Non-sync from one location. Right now we have a dvd player in each both to play music. It is all going to be run out to cp650 & 750's. I just wanted to see how everybody handles this and also figure out what kind of cable would be best to run for this(not the Cat6 but for the non-sync).  |  IP: Logged Frank Cox Film God Posts: 2234 From: Melville Saskatchewan Canada Registered: Apr 2011 posted 08-28-2012 12:44 PM                        Thread  |  IP: Logged Stephen Frazza Expert Film Handler Posts: 161 From: Nutley, NJ, USA Registered: Mar 2004 posted 08-28-2012 01:04 PM                        Thank you, but I was talking about how to run it hardware wise not what to play.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 08-28-2012 01:34 PM                        I hate centralized non-sync music systems. If a theatre cannot cough up $200 or so per screen for a CD player, then it deserves to go out of business. That said, the usual method is to use a distribution amplifier (Smart and Ultra-Stereo made/make these) and long runs of shielded cable. This often results in hum, as these systems are typically unbalanced. A better approach is to use transformers at either end to balance the signal and unbalance it at the processor end. Sadly, transformers are not cheap.  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 08-28-2012 01:42 PM                        quote: Scott Norwood I hate centralized non-sync music systems. If a theatre cannot cough up $200 or so per screen for a CD player, then it deserves to go out of business. Why do you hate centralized non-sync music? What is wrong with each auditorium having the same music at the same time? Small theaters it would be disturbing to have the hall flooded with 6 or 7 theaters all playing a different song at the sometime. I doubt you can be in more than one theater at the same time can you? So what is your beef on it? If the system is set up right there will be no hum.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Action films get different music from foreign films, etc. Also, I dislike the idea that if the theatre's one CD player fails, no theatre gets intermission music.  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 08-28-2012 01:56 PM                     quote: Scott Norwood This often results in hum, as these systems are typically unbalanced. quote: Ron Funderburg If the system is set up right there will be no hum. Nonsequitur. His complaint is that hums occur in many instances of these installs, not that it happens in all of them.  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 08-28-2012 01:57 PM                        OIC! I have done the same thing from time to time. I prefer music and a trivia slide show to the umm way we do it here. I don't like ad's in a theater other than static slide type advertising. Was just curious. Chris, I wasn't saying his complaint was valid I was saying it doesn't happen when it is installed right.  |  IP: Logged Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 08-28-2012 07:20 PM                     Component Engineering makes a transmitter/receiver music distribution system that works very well. One transmitter is installed at the CD/DVD/MP3/etc player, and one receiver is installed in each sound rack. The receivers are daisy-chained, so no need for home run from each sound rack back to the DA. http://www.componentengineering.com/audio_dist.html  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 08-28-2012 07:34 PM                     Given that a lot of cinema sound systems have gone to utilizing cat 5/6 ethernet cabling for most of the run, I'd think something similar for this would work pretty well. I'd imagine with having significantly shorter audio wiring, you'd have much less of a chance for the hum (but I've been wrong before ).  |  IP: Logged Tom Wienholt Master Film Handler Posts: 371 From: Towson, MD, USA Registered: Dec 2002 posted 08-28-2012 07:51 PM                     If you have a hum problem, you could always use a ground loop isolator to stop it. Yes, I understand that "if wired properly" there will not be a hum. But, the ground loop isolator is a simple fix if the problem cannot be diagnosed.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

I have not seen it before (although I have pretty much been out of the multiplex business for the last couple of years).  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-29-2012 06:52 AM                     You can have a networked consumer-type media player installed for each screen. Like a WD-TV. They can be configured to play from ethernet, or local storage (USB stick). All options there. You can also control them remotely, either all playing the same content, or each or some of them play individual playlists. It's certainly a bit more complicated to set-up than just a distributed audio wiring, but it may be worth it. The cost of about 80-100US$ per unit could be less, using the existing CAT6 cables, compared against a dedicated symmetrical analog cabling or the like. Aditional bonus - these can also play images, video, etc. through the digital projector - intermission slides, ads, private photos if the auditorium is rented for a party or something. - Carsten  |  IP: Logged Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 08-29-2012 08:29 AM                     quote: Scott Norwood The Component Engineering thing looks interesting. Is it a new product? Not at all. My first encounter with the system was over 12 years ago.  |  IP: Logged Stephen Frazza Expert Film Handler Posts: 161 From: Nutley, NJ, USA Registered: Mar 2004 posted 08-31-2012 01:53 PM                        Any idea to the cost of the Component Engineering system?  |  IP: Logged
