Author Topic: dolby sr probelm Angel Hultzsch Film Handler Posts: 16 From: Caracas, Miranda, Venezuela Registered: Nov 2001 posted 06-17-2003 07:00 PM                    Hi, i need help because i have a problem with the dolby sr: in some trailers the dolby digital is reading improperly, this cause the revert to dolby sr, so the diference is too obvius, the sr sound is distorsioned and loud "when the center chanel have a low frecuency or high frecuency this make a distorsion, the same for the surround, this is bad for the show and the theater, we use a prevost p93 srl, if someone can help....  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

In the meantime, try playing trailers in mono (instead of SR). It will probably sound better (less bad) than a misaligned SR system.  |  IP: Logged German Marin Expert Film Handler Posts: 227 From: Verbania (VB), Italy Registered: Jul 2001 posted 06-17-2003 08:26 PM                     The problem could be those "some trailers". What about the rest of the trailers? mosca.  |  IP: Logged Mark J.

How does the feature (and all the other trailers) sound in the theater if you play them all in SR? If they all sound horrible, then you most likely need an A Chain. If everything else sounds OK in SR except for your digital defective trailers, then the trailers are defective on the analog side too.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

If you play back SR tracks with A-type NR cards it can sound rather unnice too.  |  IP: Logged Elvis Navas Film Handler Posts: 13 From: Caracas, Venezuela Registered: Apr 2003 posted 06-18-2003 08:28 AM                     hello angel, what I have to do to make you understand?

This is the traslate for this: quote: hola angel, como hago para que me entiendas? COÑO!!!!!!!!!!

The samething in english and spanish, but it's more expressive in spanish.

This could be no one's fault. Dolby's tone loops are a joke. I really wish they would do something about the quality control on them. The levels are all over the place from batch to batch. Without the tone level set properly (due to a faulty loop), that could cause some of the problems Angel is describing.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

We don't have the buzz track to do the right alignment (how do we do to buy a film from a foreign country and pay them?) and Angel know that. It cost little more than $250 but the BIG PROBLEM is how or where to change Bolivares to dollars. We've spoken to him about this topic a several times, however he brought the problem here knowing the way to fix it. Sorry for this.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 06-18-2003 06:36 PM                     Couldn't you temporarily use the Dolby tone loop and the oscilloscope as a last-resort lateral centering film? Adjust until both waveforms are the same size or something like that? Then double-check with a strip of film that has DTS timecode? [Edit -- I just read the original post again and noticed that there is another problem...Dolby Digital is defaulting to analog. That's more serious than the A-Chain problem, if you ask me...]  |  IP: Logged German Marin Expert Film Handler Posts: 227 From: Verbania (VB), Italy Registered: Jul 2001 posted 06-18-2003 07:52 PM                     We've done all with the 69T. Both the Digital and analog reader on this projectors (Prevost P93) are too critic and the just 69T isn't enough. The buzz track will come here into the next two weeks. The problem isn't too BIG as it appear. In just one auditorium the Digital is really bad (in the CP650 there's a " - ", the voltage is good, the LED is new) and Elvis has sweated a heap using 69T and 69P. The film's running on SR without problems. We're waiting for buzz track to do the right work.  |  IP: Logged
