sound changes independent of the projector’s dowser position. Adjustment of the roll down on the
upcoming projector may be necessary to keep the change-over “seamless”.

Film Breaks and Edits
The DTS-6D processor will automatically track any length edit. A 30 millisecond cross fade makes the
edit transparent. Make sure the automation has switched to digital format after show re-start.

Maintenance
The timecode reader lens should be blown off with compressed air once a day to remove any dust build
up.
AFTER THE SHOW
When returning a DTS encoded movie back to the distributor, put the movie discs back into the yellow
reel. Put the loaded yellow reel in the can with the film. Remember to remove the DTS trailer (logo)
film so you may use it with other DTS encoded films.

Moving the DTS System
Many theaters are moving their DTS systems from house to house following DTS movies. If you are a
theater that does this, there are a few steps that must be taken to ensure proper digital playback. Give
the person moving the system
at least one hour’s time to complete the task.
* The DTS-6D surround channels must be wired into the cinema processor and match the type surrounds
(mono/stereo) present in the theater.
* The DTS-6D offset switches may have to be reset. Many people have purchased extra brackets and are
marking them with the offset number for that projector. Having a bracket on every projector saves time when
installing/moving the reader head. Remember, the unit’s offset switches must be correct for the digital sound
track to play in sync with the picture. Change-over houses must attach the reader heads at the same place on
both projectors so their offset numbers match.
* The DTS-6D level pots must be recalibrated for its new location. Use a SPL meter and a
DTS SETUP
disc to
measure the pink noise in the theater. See Section 4.1 . Do not simply point the meter out of the port-hole
window : This will not give you proper readings. SPL readings must be taken in an empty theater with the
screen’s curtain open and the cinema processor’s fader to “ 7 ”.
* Whenever anything is changed on the DTS system, be sure to go into the theater at the start of the first
screening. Check that the sync and levels are correct. Watch mouth movements (lip sync) on screen to verify
proper offset.
** WARNING WARNING **
Failure to correctly recalibrate the “moved” DTS-6D unit will result in improper playback levels
and lip sync.
