TROUBLESHOOTING TIPS
Its always a good idea to stand in the theater and listen to the first few minutes of the movie.
Listen to the sound level and general quality of the sound. The sound track should be in sync
with the picture (wait for a dialogue scene) and played at a comfortable level. Even though not
every scene will have surround material, do your best to listen for the surround speakers. Most
opening musical sequences have surround information. Be sure the movie discs match the film
you are playing. Feel free to contact DTS and ask for help.

••
• I have a DTS print but I don't have discs
Contact your film distributor and ask for the disc(s). Remember. a film that runs less
than 90 minutes will have only one movie disc - it should also be labeled “one disc
only”. Movies running over 90 minutes will have two movie discs. If the movie runs
over 3 hours and 20 minutes, then you will receive more than two discs and special
show instructions.
• Film not in sync or doesn't sound right
Turn off the DTS-6 unit. Check and listen that the movie is playing in optical format.
Let the film finish playing in optical. Do not attempt to remedy these problems
while playing in DTS. The theater's technician should perform a full DTS quality
check with the setup discs and verify sync with the demo film. Give the technician at
least one hour to complete the test and alignment.

••
• Volume too loud
Turn down the fader pot on cinema processor. Do not adjust the DTS-6 trimmer pots
behind the blue panel. If sound level needs adjustment after it switches to digital,
contact your theater's technician and request a B chain alignment (to DTS).
• DTS-6 won't switch into digital sound
- Verify movie discs are in the DTS-6 unit. Push both CD-ROM drive’s EJECT button
and if nothing comes out, get the movie discs and insert them in the drives.
- Verify the movie discs match the movie. Push the
EJECT button, and look at the
movie discs. If the title doesn’t match the film, the DTS-6 will not play. Find the
correct movie discs, insert them in the CD-ROM drives, and do the next step below.
- If the movie was recently changed, first power off the DTS-6 unit. Wait three
seconds, then turn the player back on. The DTS-6 should reboot in about 30 seconds
and play in digital if the correct movie discs are in the CD-ROM drive(s).
- If the unit does not switch to digital, verify the green LED on the reader head (on the
projector) is glowing brightly and steadily while the movie is running. If the LED is
dark, then verify the film is threaded through the DTS reader and that the film has a
timecode strip (located between the picture and the analog sound track). If no
timecode (dots and dashes) strip is seen, call the film's distributor and request a DTS
print.
• Switches out of DTS digital
- The sound should default to optical when the DTS-6 does not see timecode for four
seconds. Verify the green LED on the DTS reader head is glowing brightly and
steadily while the film is running.
