Author Topic: JSD now using AC3! JS Processor has been replaced by the JSD Robert Schultz Film Handler Posts: 28 From: Tehachapi, CA, USA Registered: Mar 2004 posted 11-09-2004 10:10 PM                        The JS Processor came to its official end today. USL announced today that the JS will still be supported but it will no longer be sold because integrated circuits in its design can no longer be found. This processor came a long way through cinema history. It would appear that USL will replace the analog JS with a new processor...the JSD. I worked with many JS processors over the years and they have proven their value many times over!

Things don't last forever....rumour that Dolby will stop production on the CP45 soon.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-10-2004 08:47 AM                     Analogue Devices is a pain to any circuit designer there VCA chips are used by both Smart and USL in the matrix, noise reduction and VCA modules and most have been discontinued with no 3rd party replacement  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash. USA Registered: Sep 1999 posted 11-10-2004 09:56 AM                     I just went to USL's website and clicked on sound processors and news. Didn't see anything about a JSD anywhere or about JS being discontinued.  |  IP: Logged Clint Koch Phenomenal Film Handler Posts: 1435 From: San Luis Obispo, CA, USA Registered: Feb 2002 posted 11-10-2004 11:41 AM                     The USL web-site is not up to date and Rob is correct, the JS-series will be supported yet we will not be able to sell any new full units. The replacement JSD-80 is being signed off by the engineers and will be in full production soon. We had hoped the JSD-80 would have been released before we had to pull the plug on the JS-series yet we are just a little behind.  |  IP: Logged Steve Scott Phenomenal Film Handler Posts: 1300 From: Minneapolis, MN Registered: Sep 2000 posted 11-12-2004 09:35 AM                     We are installing 7 JSD's in our new Monticello theater. After running JS-220's for many years, I'm looking forward to seeing what's USL has cooked up now.  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash. USA Registered: Sep 1999 posted 11-12-2004 10:27 AM                     I've never seen a JSD. What does it look like? What features does it have? Can you still use the JPN Pink noise card with this unit?  |  IP: Logged Clint Koch Phenomenal Film Handler Posts: 1435 From: San Luis Obispo, CA, USA Registered: Feb 2002 posted 11-12-2004 11:02 AM                     As I do not think that I should use this forum as a sales tool I would ask that anyone wanting more information on the JSD-80 please e-mail me directly and I will relay the information. Don't want to piss off the moderators.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 11-12-2004 11:27 AM                    Not to usurp the moderators but I don't think a basic description or a picture if you have one would be inappropriate here. Many are or will be curious.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 11-12-2004 11:45 AM                        I'm with Steve, and I _am_ one of the moderators. There's no problem with a basic description of what the product does or how it works, especially if it's in response to a question or comment raised on the forum. Better yet, a basic description with a link to the (hopefully soon-to-be-updated) USL web site would give potential customers a place to go for more information. I should also point out that the "reviews" section of this site could stand to be expanded and that if USL or any other manufacturer is interested in having its product reviewed and has a sample model available for loan, Brad or anyone else might be interested in writing a review of it.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-12-2004 02:02 PM                     quote: Steve Scott I'm looking forward to seeing what's USL has cooked up now. Well, you are not far off in that statement thats for sure. We have a number of VX crossovers in use and they run hotter than blue blazes . I believe the new processor is based on the same box/technology so be absolutely sure to install at least double space rack vent plates above and below the new JSD. The enclosure is essentially sealed and has little to no air flow though it. FYI: We did experience an inordinate number of board failures with the VX units and kept having the board failures till we added the extra vent panels above and below each unit at all locations. I will add that the VX sounds great for a digital DSP based piece, and since adding the vents they have been totally reliable. So if the good sound quality of the VX is any indication of how the JSD will sound then bring it on.... but pleeze add a fan to the thing! I can't think of a digital cinema type piece that doesn't have a built in fan to help keep temperatures within limits.......  |  IP: Logged Clint Koch Phenomenal Film Handler Posts: 1435 From: San Luis Obispo, CA, USA Registered: Feb 2002 posted 11-12-2004 03:25 PM                     Okay, here we go... In addition to all the features found on the JS-series processors the new JSD-80 series includes a host of features that support upcoming digital cinema projection. The JSD-80 supports eight channels of audio. Eight channel AES EBU input with 32K to 96KHZ sample rates on a DB25 connector. Two optional SPDIF inputs with Dolby® AC3 (pending the signing of the license agreement) or Prologic on RCA jacks for alternative content. Adjustable time delays to compensate for video projectors. Eight channel discrete analog input on a DB25 connector. Two 35MM projector inputs with A or SR noise reduction and surround decoding. Two non-sync stereo inputs with surround decoding on RCA jacks. Built in real time analyzer for A chain and B chain alignment. Built in pink noise generator. Built in EX type decoder. Individual format volume levels. Seven channels of 1/3rd octave "Constant Q" equalization. Parametric equalization on the sub-woofer channel. Integrated laptop graphical user interface for system setup. Eight outputs with active balance circuitry. State of the art 96KHZ sample rate hardware with 106 dB dynamic range. Total harmonic distortion less than 0.015%. One microphone input on a DB9 connector. Automation on a DB25 connector or via RS232. Plug compatible with existing DA20 or DTS6 players. Hearing Impaired output. Thank you Mark for the kind words about the audio quality of the VX. This unit is based loosely on the VX yet will not have the heat problems the VX had. Once we get into full production we will submit the unit for review. Thank you Scott for letting me get this information on the thread. By the way this is the unit you and I spoke about in the chat room a while back. Any time that any of you want to ask me questions please feel free to e-mail or call at 805-549-0161.  |  IP: Logged Dave Cogley Film Handler Posts: 4 From: San Luis Obispo, CA Registered: May 2004 posted 11-12-2004 03:50 PM                        To demonstrate the capabilities of the new JSD-80 we have posted a link to the laptop interface software. This installation also contains a manual for use of the JSD-80 processor. Our website will be updated in the next couple of days to provide more information. Please feel free to provide feedback directly to me (email) or on this forum. JSD-80 Laptop Interface Software Thank You  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-12-2004 04:19 PM                     quote: Clint Koch State of the art 96KHZ sample rate hardware with 106 dB dynamic range. That dynamic range seems a bit limited for a 96khz system? Is this a 24 bit system of is it lower than 24? If lower than 24 how come? Typically 24/96 systems exceed 120 plus db dynamic range.... Thanks!

I will ask him to clarify and get back to you.  |  IP: Logged
