Timecode Reader Adjustment.  See Figure 5.

Eject the 

SETUP DISC

 and insert the 

DTS 6-TRACK DEMONSTRATION D-1

 disc.  Thread the 

DEMO REEL

through the projector 

and 

the DTS reader head.

The 

DEMO REEL

 has a specially printed leader for setting the timecode head offset. Start with the offset

measurement start mark, 

“00”,

 at the timecode head’s red LED (inside the lens).  Read the number at the

projector’s optical sound head and set the DTS  processor 

TIMECODE HEAD OFFSET

 switches to this

offset number.  The offset number must be between “15” and “70”.  If the offset is not within these
parameters, relocate the reader head(s) on the projector(s) until a valid  number is achieved.

If 

no

 

DEMO REEL

 is available, delay can be calculated by counting the number of picture frames 

from

 the

DTS reader head red LED (lens) 

to

 the projector’s picture (“film”) aperture.  Multiply the result by 1

.

25

and subtract one.  Set the 

TIMECODE HEAD OFFSET

 switches to this number.    EXAMPLE

:

  27 frames X

1

.

25 = 33

.

75 - 1 = 32

.

75 offset.  Round this number off to the next whole number.  So, “33”  would be

the offset number.

REMEMBER:  When using the 

counting frame

 method, frames are counted from the timecode reader lens to

the 

picture aperture

.  And, when using the numbered film strip method, thread projector with the “00” at the

timecode reader lens and read the number at the optical sound head (solar cell).

IMPORTANT:  Make the same size film loops inside the projector when measuring the offset as when
running a movie.  Failure to do so will result in improper sync when the movie runs in DTS digital sound.

Run the DEMO REEL

.  The green light on the Timecode Reader Head should light when timecode is

read.  The light should be bright and steady.

Listen test

.  Go into the theater.  Watch and listen to the demo film.  Verify the sound sync to picture is

correct.  Check the front and back of the theater.  If any delay is seen adjust the 

TIMECODE HEAD OFFSET

switches as necessary to obtain proper sync.

Listen through the entire reel to be sure that no distortion or breakup occurs.  If running a change-over
theater, play the demo film a second time through the other projector.

Check the fail-safe operation.

While the film is running in digital, slip a business card into the timecode reader head, (between the film
and the lens as to block out the timecode from being read) for at least six seconds, while the show is
running. The cinema processor should switch back to the optical format.

There should 

not

 be a dramatic level difference between optical and digital sound (in a quiet scene).  If

there is, recheck the “B” chain and the DTS-6D level settings.

Remove the business card and verify the cinema processor switches back to digital format within six
seconds.
