FAIL-SAFE TEST Note: Analog fallback not used on DTS 70mm film.
•
••
• Thread DTS 70mm encoded film through the projector and DTS reader(s).
•
••
• Load matching CD-ROM discs into the two DTS players: One disc (set) in the main
unit and the second in the “fail-safe” player.
•
••
• Start the projector. The cinema processor should pulse to digital and both players
should be playing in digital. Their
SYSTEM lights should be blinking and DIGITAL
lights should be on solid. Turn up the booth monitor so that the sound track is heard.
•
••
• While playing in DTS, eject the discs from the main player. The second (or “fail-
safe”) player should immediately take over. No interruption in sound should be heard.
•
••
• Load discs back into the main player. Once the main player starts playing in digital,
eject the disc from the “fail-safe” player. No sound interruption should be heard.
Listen Test
•
••
• Run a reel of DTS 70mm film. The green light on the reader should brighten when
timecode is read. The light should be bright and steady, and not flashing. A lot of
flashing indicates a problem.
• Go into the theater to verify quality sound and a comfortable listening level. Also,
verify good lip sync.
OPERATION
•
••
• Thread Film Through The DTS Timecode Reader
Verify same size loops through the projector as done when checking the offset number.
Failure to do so will result in the picture being out of sync with the digital sound track.
•
••
• Verify Offset
If the DTS reader has been changed from 35mm to 70mm (or visa-versa), remember to
change the offset setting on the DTS player. Failure to do so will result in the picture
being out of sync with the digital sound track.
•
••
• Verify Movie Discs
Verify the discs match the movie (“Jurassic Park” film with “Jurassic Park” movie
discs). If the film and discs don't match, the digital sound track will not play.
If a second DTS player is used for 70mm fail-safe, load a second set of discs into this
unit. These discs should match the discs in the main DTS player.
Reboot players to ensure the discs are read by the players.
•
••
• DTS recommends the show be pre-run. Check that the timecode reader green LED is
bright and steady, and the system performs properly. Check all reels for good timecode,
if time permits. Occasional blink of the TIMECODE LED is normal.
•
••
• Maintenance
The timecode reader’s lens should be blown off with compressed air once a day to
remove any dust build up. The
CD-ROM drives may be cleaned using a “CD-ROM
cleaning disc” – available at any computer store or from DTS.
