Author Topic: DTS XD-10 delaying sound changeover Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-14-2005 01:38 AM                        Our XD-10 has developed the habit of not switching to the next reel's sound fast enough. When the splice goes through, it continues to play the sound from the outgoing reel until the BEEP is heard, then it instantly switches to the incoming reel. It doesn't do this all the time -- when we screened ROBOTS the other night, the sound played flawlessly through the whole movie. But on our last show tonight, I heard that damn BEEP three times, after reels 1, 3 and 4. Anyone else experienced this, and any suggestions? (We use a platter, so there's no possibility of changeover issues. Our audio processor is an Ultra Stereo JS200 series. And the software in the XD-10 has been upgraded.)  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 03-14-2005 09:51 AM                        I had this issue with an old reader. The LED was poor so that at each reel change the player didn't receive the new timecode and proceed with the end of file that contains the "beep". I would check for the RED voltage and the installation of your reader before. Remember that if the reader is brand new it is very possibile that the LED voltage has dropped a lot after the first months.

Registered: Jan 2004 posted 03-14-2005 01:29 PM                     As Antonio stated the voltage of the LED could be too low to read the timecode. However, if the timecode is dropping out you should see the green light on your TC reader switch off. Is it doing this?  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-14-2005 01:35 PM                        No, the light is nice and bright. No dropouts back to analog at all -- it just takes an extra second to switch reels.  |  IP: Logged Bruce Hansen Jedi Master Film Handler Posts: 847 From: Stone Mountain, GA, USA Registered: Dec 1999 posted 03-14-2005 06:13 PM                     The DTS player will keep playing for about 5 seconds without time code, before it switches to analog. If there is a problem at the splice, and it takes a little time to start reading time code again, you may hear the beep. Try cleaning the LED, and the lens. Check the GAIN adjustment in the reader (R16). Do not shine any light into the reader while making this adjustment, it can affect the reading. With all due respect to DTS, This is NOT adjusting the LED voltage. The red LED is feed from the 5 volt supply through a 360 ohm fixed resister (R15).  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 03-15-2005 12:55 PM                        Check trhe gain with a meter you would be surprised when you'll find it at 2V instead of 4V!! However, I knew just today that what you are describing is a known bug of the current XD10 software and it will be fixed in a couple of months. I would check the reader too, however!

Registered: Jan 2004 posted 03-15-2005 01:28 PM                     If it's a bug in the firmware, couldn't you just downgrade? And what causes this bug to pop out? I've had no problems like this.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-15-2005 02:12 PM                        I cleaned the reader and it still did the problem last night -- but just once this time. Jeeez I hate intermittent problems.  |  IP: Logged Brad Allen Jedi Master Film Handler Posts: 688 From: Evansville, IN, USA Registered: May 2000 posted 03-15-2005 09:48 PM                     Check the voltage of your readers LED as per DTS. Fix's many ills. My Xd10 is not exhibiting these problems and has been updated as well.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-15-2005 10:21 PM                     I doubt that its his reader adjustment. We check that on every service trip to his location. Have you called DTS yet Mike?

Fundamentally, it seems like the DTS firmware should be able to prevent this problem. We did not really have the opportunity to debug it at the time, but whether it was 2-pop on the head of the incoming reel or a post-tail sync-pop on the outgoing reel, the DTS encoding box should not be including that part of the printmaster on the CD. Or the decoder should know what the beginning and ending timecode for a reel really are, and not playback sound outside those bounds them without some special flag or switch (input via keyboard, DIP switch, or whatever). Analog reversion or plain silence would be vastly preferable to those sync pops. Oh, on a practical level, we had significant problems with the print this happened on drifting in and out of DTS, to the point where it was unbearable and we ran it in analog. Presumaby there is a correlation here. No flickering timecode lights, however, whatever that means. --jhawk [edit: Motorcycle Diaries sted Monsier N.

Follow the instruction on DTS' techcenter, it is simple. And wait for the upgrade if it does not solve!
