Author Topic: DTS 6AD Patrick A. Meister Film Handler Posts: 22 From: Switzerland Registered: Aug 2003 posted 04-05-2004 03:00 PM                     Hello Can you tell me something about the Digital/Analog processor of DTS? Is it good? Kind Regards Patrick  |  IP: Logged Daryl C. W.

Get a real CP and attach a DTS-6D to it.  |  IP: Logged Ron Lacheur Jedi Master Film Handler Posts: 650 From: British Columbia, Canada Registered: Feb 2002 posted 04-05-2004 05:14 PM                     Patrick, if you do a search on the 6AD, you find a lot of information about the unit and why it's not a good idea to get. Mostly do to the crappy faux SR that Daryl mentioned above.  |  IP: Logged Oliver Pasch Film Handler Posts: 53 From: Europe Registered: Jun 2002 posted 04-08-2004 02:23 AM                    Sorry, but i can't support the opinions here about the optical SR decoding of a 6ad, actually i think it's the opposite: it's good, if not better than some (CP-45) "real" CPs, definitely equivalent, the only thing you need to consider is HF-alignment. Where a "real" CP pardons mistakes (= too much HF) rather friendly, a 6ad needs "correct" alignment. Use the auto-HF-alignment on a CP-500 or - 650 and you won't be amazed of optical sound of these units as well.  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 04-08-2004 02:42 AM                     Manual alingment of everything, including equalisation has always been my favourite. That is the reason I love CP65 and Smart MOD VI processor. Because in CP65 you manually equalize EVERYTHING. And in MOD VI you have full band equalization in all channels and a very good SR demodulation. All processors are good in their own way. Technicians, Installers, Projectionists need to learn that no automatic configuration is good when installing a processor. That is my opinion anyway.

Why not connect a SRA 5 to a DTS 6 AD to get REAL SR? Max  |  IP: Logged Daryl C. W.

Having SR fold down into centre surround is pretty lame too, and that's just what the DTS-6AD likes to do.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 04-08-2004 02:57 PM                     Dolby should have never made the CP45. It is an amazing piece of shit...just like the DTS6AD. Stay away from it. The sound quality leaves much to be desired and their SR emulation is absolutely horrid.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 04-08-2004 03:05 PM                        I know that everyone loves to trash the CP45, but, honestly, the one that I used to work with sounded fine. I agree, though, that the quality of construction is nowhere near that of other Dolby units and I would expect it to become unrepairable much sooner.  |  IP: Logged Fabrice Dubourg Film Handler Posts: 43 From: Granville, France Registered: Feb 2003 posted 04-08-2004 03:17 PM                     Brad, what do you prefer ? CP45 or CP50 !  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 04-08-2004 03:30 PM                     The CP50 is a FAR better processor.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-08-2004 06:16 PM                     Brad, You need to calrify that a bit... What I think you really mean is that an UPGRADED CP-50 is better than a CP-45.... I've always felt that a CP-45 IS actually better than a stock- original CP-50. The 45 does have SR noise reduction and a much, much higher quality fader circuit. Take a 20khz sine wave, feed it through a CAT 117 fader card and take a look at the nasty crossover notch at the zero point on the output sine wave. VERY UGLY! The 45 EQ facilities do leave a bit to be desired but if you have the good fortune to have designed the room correectly and equip it with decent speakers you shouldn't need too much of the inadaquate EQ in the 45 anyway. The build quality of the CP-45... No where near as good as an Ultra Stereo JS series processor! But I can say that I've never had any of the three CP-45s fail here in Utah.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 04-08-2004 09:49 PM                     Mark...the CP-45 only has Dolby-SR emulation not the real thing. At least the CP-50 can have the real thing...the CP-45 can't! Steve  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 04-08-2004 10:05 PM                        What's so hard about SR that it must be emulated rather than the real thing installed? I mean c'mon... it's SR! It's not like trying to run Windows on a Mac. It's ancient technology and should be easy to duplicate, especially inside Dolby's own CP's. I've heard that Dolby has had issues getting SR to be as good as it used to (SR/A cards, etc). It can't be hyper expensive, either... again it is old, ancient technology. Even Dolby can't get it right? That doesn't say much for the company's efforts. Seriously, why is proper SR so damned hard to get?  |  IP: Logged
