Why would a DTS unit decode a Dolby data stream? Do DTS and Dolby get along now? Do the latest Dolby processors also have CD trays for DTS discs?  |  IP: Logged Mark Strube Master Film Handler Posts: 322 From: Milwaukee, WI, United States Registered: Feb 2007 posted 04-10-2008 02:05 AM                        In which case I believe my original recommendation would be a good solution. (USL product connected to XD10P for consumer DD decoding.)  |  IP: Logged Sebastian Binz Film Handler Posts: 32 From: Cologne, Germany Registered: Nov 2007 posted 04-10-2008 05:20 AM                     I wonder whether the optional digital input board (DI83) of the USL JSD-80 in its "D" version would also work in the XD10P, as the two units are using the same hardware? That input board uses two RCA jacks on Non/Sync and Aux to handle S/PDIF signals from a consumer AC3 bitstream, which any DVD player capable of DolbyDigital decoding can supply. We recently installed the JDS80D and are very pleased about its performance.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 04-10-2008 07:12 AM                     Here's what I know from experience. Ultra Stereo JDS80 will decode AC3 & AES/EBU not sure about consumer DTS DTS XD10P will decode AES/EBU and afaik consumer DTS, but not AC3 DTS XD10 has an SPDIF input (at least all the ones I've ever seen do) and will decode DTS, you must however have the appropriate licence from DTS to activate it. CP650 will decode AES/EBU & PCM. Until today, I hadn't seen this looks like a neat solution!  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 04-10-2008 01:10 PM                        Damn double post!  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 04-10-2008 01:10 PM                        Actually, Joe, many DVD units out put DTS or was that something you missed? Why even PS3 out puts DTS! You should check it out there have been a lot of changes since 1997 when DVD started!  |  IP: Logged James Ness Film Handler Posts: 47 From: Houston, TX, USA Registered: Jan 2008 posted 04-10-2008 05:10 PM                        So just checked, none of our CP650's have the EX card installed. So unless I get something like the ECI-60 I'm shit out of luck?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 04-10-2008 07:08 PM                     Back up the bus get a dvd player with an analogue 5.1 output and make a cable to connect to the external analogue input Or soundblaster made a standalone decoder that took the digital out of a player and gave you dolby 5.1 analogue outputs  |  IP: Logged Ron Funderburg Jedi Master Film Handler Posts: 814 From: Chickasha, Oklahoma, USA Registered: Nov 2007 posted 04-10-2008 08:03 PM                        Gordon I actually did what you describe and input to the individual inputs on the Processor unit. It worked great but you had to turn the DTS unit off or it would rob half your volume.  |  IP: Logged Tristan Lane Master Film Handler Posts: 444 From: Nampa, Idaho Registered: Feb 2002 posted 04-10-2008 09:14 PM                     The XD10P has a 25 pin AES connector on the back. Can Spdif be used here? If so, just hook up to channel one. I believe there are some issues with gain if you don't hook it up properly because AES is balanced and spdif is not. The USL JSD-80 (pretty much the same internals as an XD-10P) has an RCA jack on the back for Spdif input. I've always wondered why DTS left that out on their models.... Gordon is referring to the Sound Blaster "Extigy" models. They are great for decoding AC3 and such into six analog channels.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 04-10-2008 10:47 PM                        quote: Ron Funderburg Actually, Joe, many DVD units out put DTS or was that something you missed? In order to output DTS, the DVD must have DTS encoded onto it. How many DVDs have DTS? Very, very, very, very, very, very few when compared to those which have Dolby Digital. DTS keeps trying to establish themselves in the home market, but they keep coming in waaaaaaaaaaaaaaay behind Dolby. A brutha just can't get a chance.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 04-10-2008 11:34 PM                        This is probably a question for the home forum, but I'll ask here for now: what, exactly, is consumer DTS and why would anyone use it? I know that, in principle, it's an alternative encoding format and that it, in theory, provides superior sound quality when compared with Dolby AC3, but does it really do this? Does it have any other advantages in real-world situations? Wouldn't it be better for DVD authors to use the extra disk space for higher video bitrates, rather than a duplicate soundtrack? Or does it sound so much better as to justify the use of the space?  |  IP: Logged Mark Strube Master Film Handler Posts: 322 From: Milwaukee, WI, United States Registered: Feb 2007 posted 04-10-2008 11:45 PM                        On standard DVD's, Dolby Digital is typically running at 448kbps, whereas most DTS runs at 1.5mbps... and purports to retain more detail in the audio. Most people who have reviewed one against the other find a small difference, but it never seems to be enough to justify the extra disc space required. It was simply a marketing ploy that pretty much failed. It's happening again with Blu-Ray's many different flavors of lossless audio, except the difference is that it's not really taking away from video bitrate.  |  IP: Logged Blaine Young Master Film Handler Posts: 477 From: Kirkland, WA, USA Registered: Sep 2006 posted 04-11-2008 12:31 PM                     quote: Brad Miller He said he had a CP650. That comes standard on the CP650. Check your model numbers Some of the CP650s do have EX and some do not - at least that is the way when we bought our 16 units - 5 have EX, the others do not. On the consumer DTS issue, only the first handful of titles used 1.5mb/s bitrate. Starting with "Saving Private Ryan", DTS started using a 'half-rate' 768kb/s stream to allow the track and the film to actually fit on the disc. There were still a handful of dual releases (Jaws, Saving Private Ryan), but eventually they just dropped DTS. With Blu-ray, the rules have all changed and DTS is there from the very beginning. And we praise FOX for putting DTS-HDMA tracks on every release. I am faily sure there is not any cinema equipment that will decode consumer DTS. The codec is completely different. As Gordon said, if you want DTS from a DVD/Blu-ray disc in the theater, you'll probably need to use the 6-channel inputs.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 04-11-2008 12:58 PM                     Nope, check your model number. A CP650 includes EX. A CP650D does not. I never said Dolby's model numbers were very well thought out, but regardless look here.  |  IP: Logged
