Author Topic: Sound Processors for D-Cinema Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 10-02-2006 06:45 AM                     What Sound Processors are being used in D-Cinema installations? Are there any processors in use today that could not be used for D-Cinema? Cheers Ian  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-02-2006 07:50 AM                     There are two primary processors being used. CP-650 and the USL JDS-80 and it sister processor from DTS. Both have the option of having an SPDIF digital input. With the addition of an external D to A such as the DMA-8 and others such as the RAMSA outboard unit you can utilize any processor with an aux. 6 channel input.

(North of Dallas) Registered: Jun 99 posted 10-02-2006 10:00 AM                     Ian, I have installed a USL JSD-80 and am using the AES/BSU digital audio input. It is a DB-25 connection. I'm not sure if there is an optional component that you have to order in order for the processor to decode the digital data. I selected the digital audio input, because I had a slight ground loop using the analog cable.  |  IP: Logged Chris Trainor Expert Film Handler Posts: 161 From: Greenville, RI, USA Registered: Jun 99 posted 10-02-2006 11:24 AM                        Ian, the input needs to be 6 discreet channels. L/C/R/lS/rS/Sub. Which basically prevents you from using regular non-sync inputs. --Chris  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 10-02-2006 01:41 PM                     I thought most audio setups able to handle DTS, Dolby Digital & SDDS could accomodate the LPCM surround format of digital cinema. Does this mean the Dolby CP-65 and Smart processors at our local Carmike will get replaced when their Christie CP2000 systems get installed?  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 10-02-2006 01:57 PM                        If the DLP system provides analog outputs, they can easily be connected to the format 10 input on the CP65. This would preclude using a DA20 as well, though, unless some sort of switchbox is installed. Does the DMA-8 connect to the format 10 input and, if so, can it accommodate an installation with an existing DA20?  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 10-02-2006 02:01 PM                     Scott. Yes to both questions, and it works very well.  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 10-02-2006 03:38 PM                     If you don't need the DA20 to switch automatically or under automation control (unlikely unless you're running digital cinema with an analog backup simultaneously), you can connect connect up to the CP200 passthrough input of the DA20. When the DA20 is off, the passthrough is connected to the CP65. --jhawk  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?" Posts: 4143 From: Boston, MA Registered: Apr 2002 posted 10-03-2006 02:20 AM                        Scott - when you install a DMA8, the existing external 6-channel from a DTS processor or DA20 is routed *through* the DMA8 and can both be manually and remotely switched. As has been mentioned before, some digital cinema servers, like the Doremi used in the Christie/AIX installations, can also provide analog 6-channel out. Then you don't need the DMA8 and with the help of an interface board with relay-switchable inputs, you can automatically switch between d-cinema and digital sound on film.  |  IP: Logged Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 10-03-2006 03:54 AM                     Bobby That was exactly my thoughts when I posted this question. I have a variety of processors(CSP1200,JSX1000,Smart Mod 6,DTS6AD,USL105/195,CP65 soon.........can all these accept the analogue 6 channel input? or do we just throw all these onto the pile of platters when D-Cinema fully takes over. Which processors cannot accept the analogue 6 channel input? Will the new breed of D-Cinema processors sound so much better that we will have to use them?

I feel that this question is a bit premiture as I haven't even come across the idea that digital servers are standardised yet. As for raw digital output perhaps a home processer could do the processing. Perhaps its just a case of switching the sound card in the server to an analogue one ect (just think computer) The current 6 track input with the 25 pin D conecter ( I have already posted a DIY make your own cable for DVD 5.1 in one of these forums ) might be all that you need. One things for sure the EQ, Amps, and speakers wont have to change  |  IP: Logged Larry Zuverink Film Handler Posts: 98 From: Caledonia, MI, USA Registered: Nov 2002 posted 10-03-2006 07:34 AM                     But some of the show players have 6 channel analog output so a DMA8 will not be needed.  |  IP: Logged Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 10-03-2006 09:18 AM                     quote: Cameron Glendinning Well it wont be hard to beat the current dolby digital standard, lets hope they get the bit rate up a bit, perhaps up to cd standard? Digital Cinema audio is the one really good thing about the format. It far exceeds CD standard. As specified, it will be uncompressed 24 bit at either 48k or 96k samples per second (CD is 16 bit, 44.1k samples per second). It can also support up to 16 channels which can't be handled by any current processor that I know of. It would be cool if somebody who has the knowlege could make a little chart in this thread detailing every sound processor, if it can handle digital cinema and what is needed to interface it. Example: Processor..Support..............Interface ...........................Digital...............Analog CP-65........Yes......DMA-8.............None Required CP-100 CP-200 CP-50 CP-55 CP-500.......Yes......DMA-8.............CAT685 Installed CP-650 Panastereo CSP1200....DMA-8.............None Required USL JS 6 channel series DMA-8...........None Required Smart Mod 2C..........DMA-8.............None Required Smart Mod5............DMA-8.............None Required Smart Mod7............DMA-8.............None Required DTS 6AD...............DMA-8.............None Required Smart Mod VI..........DMA-8.............None Required I don't know all the panastereo, Smart and usl processors so I'll stop my list here.

Meaning, I was able to place it into my CP500 first, and then moved it down to my JSD-80. Lyle - CP-500 needs a DMA-8 if you want to process AES/BSU digital audio.  |  IP: Logged
