Author Topic: Jurassic Park: Mixed for Dolby Digital?? Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-07-2011 08:20 PM                        In Louisville, the installations that had dts did not configure the CP-200s correctly, so analogue was played with thunderous bass. Two weeks later I removed the DC from the exciter lamp during the show and all sound stopped. The dts did, in fact, run; it just wasn't set up to switch the processor. Early dts 6 channel was not significantly better than really good optical. No one knew the difference.

That isn't a place I would look for accurate information. Might go there for a laugh or two now and then, though.  |  IP: Logged Sean Weitzel Jedi Master Film Handler Posts: 619 From: Vacaville, CA (1790 miles west of Rockwall) Registered: Dec 1999 posted 11-07-2011 09:22 PM                     Louis that post made me remember the first time I saw some analog shows played with a reverse scan reader. I was shocked at how good the fidelity was.  |  IP: Logged Aaron Garman Phenomenal Film Handler Posts: 1470 From: Toledo, OH USA Registered: Mar 2003 posted 11-07-2011 11:46 PM                     quote: Bobby Henderson IMHO, the Home Theater Forum is a good bit better. Guys like Robert Harris are more active there. I still prefer Film-Tech out of them all. FT is the only place with in depth discussions about the "nuts and bolts" process behind showing movies in theaters. Agreed. I love reading Robert Harris' posts. Very very insightful.

Yep, and the dirty little secret is that the majority of the DTS presentations of Jurassic Park were the inferior 2.0 version. Only about one-third of the theaters that installed DTS installed the full six-track version. The fact that DTS, initially, was offered in two flavors has been downplayed in DTS press releases and company chronologies.  |  IP: Logged Aaron Garman Phenomenal Film Handler Posts: 1470 From: Toledo, OH USA Registered: Mar 2003 posted 11-15-2011 01:42 AM                     Anyone know if those 2.0 discs were the same 2.0 LPCM mix on the LaserDisc? If so, I'd take that over optical Dolby A any day.

Didn't you once say that all LaserDiscs have the theatrical sound mix on them?  |  IP: Logged Aaron Garman Phenomenal Film Handler Posts: 1470 From: Toledo, OH USA Registered: Mar 2003 posted 11-15-2011 10:20 AM                     Well I guess I can't speak with definitive certainty if the LaserDiscs are indeed theatrical mixes, but I'm going to assume that they wouldn't have bothered re-mixing for LD back in the day. Some have said that the DTS LD is actually mixed hot, specifically in the subs and surrounds but hot compared to what, I've always wondered. All I know is that the DTS LaserDisc (and the LPCM 2 channel track for that matter) sound amazingly better than any of the DVD releases (Dolby or DTS) and are a completely different mix than the Blu-ray.

Was the 2.0 intended to be decoded to LCRS?  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 11-15-2011 04:16 PM                     In the THX house I worked at the time we at first played the 2.0 discs through the LCR and mono surround until we went to split surround 5.1.  |  IP: Logged Jesse Skeen Phenomenal Film Handler Posts: 1517 From: Sacramento, CA Registered: Aug 2000 posted 11-15-2011 05:13 PM                     I thought the 2-channel DTS still had a discrete LFE? The way the one I ran was set up, the subwoofer was at a fixed level so turning the main volume down would make it disproportionate- at least that's what I was told, it might have just been an excuse for playing it loud.  |  IP: Logged Bobby Henderson "Ask me about Trajan."

The DTS-S system was designed for theaters that played Dolby Stereo optical. The 2-channel option at least got the DTS unit into the theater so an upgrade to full DTS-6 operation could happen later. When the DTS systems were first introduced the DTS-6 unit cost only $3500 and the DTS-S only $2500. DTS charged a $1000 fee to upgrade a DTS-S machine to DTS-6. The standard DTS-6 price was $5900. I thought the existence of DTS-S was common knowledge, at least among anyone who cared at all about movie theater sound. IMHO, the biggest embarrassment for DTS concerning the Jurassic Park debut was the large number of analog sounded theaters that didn't bother removing the attached Digital Experience flying disc snipe. This happened on most other movie releases with DTS until Spring 1994 when the sound format trailers were no longer attached to the feature.  |  IP: Logged Aaron Garman Phenomenal Film Handler Posts: 1470 From: Toledo, OH USA Registered: Mar 2003 posted 11-15-2011 05:50 PM                     I'd be very interested to see what those 2.0 discs actually sounded like. Was it some form of LPCM, or was it still the proprietary DTS compression format? I'm still guessing that while not 6 track, it sounded better than optical Dolby A.

I never saw one, since we were busy prepping for 5.1 for (future) Dolby Digital. The factory balked since they thought that 2 channel would be the norm and the discrete unit only in special venues. Discrete was hard to source, but it is amazing what cancelling the purchase order will do. btw: Jurassic was supposed to be Dolby Digital, but Dolby wasn't ready. dts was developed suddenly over a weekend; damn good job, all things considered.
