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 and up to 3 hours 

&

 20 minutes, will have three discs.  Longer movies will have additional discs

and special show instructions.

 

Film not in sync or doesn't sound right

Turn off the DTS-6D 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 

DTS 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-6D trimmer pots behind the
black 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-6D won't switch into digital sound

- Verify movie discs are in the DTS-6D unit.  Push both 

CD-ROM

 drive’s 

EJECT

 button and if nothing

comes out, get the movie discs and insert them in the A and B 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-6D will not play.  Find the correct movie discs, insert them in
the 

CD-ROM

 drives, and cycle power.

- If the movie was recently changed, first power off the DTS-6D unit.  Wait three seconds, then turn

the player back on.  The DTS-6D 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 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 picture and analog
sound track).  If 

no 

timecode (dots & dashes) strip is seen, call the film's distributor and request a

DTS print.

 

Switches out of DTS digital

- The sound should automatically default to optical when the DTS-6D 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.  If the light on the 

CD-ROM

 drive(s) is on solid when film is playing, it means they

cannot read disc:  Try swapping discs.

 

Switches out of DTS digital (continued)

- If the 

TIMECODE

 LED on the DTS-6D or reader head is blinking, gently squeeze the film between two

fingers as it exits the reader head.  Do the same at the entrance of the reader.  If the LED stops
