• The DTS “Stand Alone Trailer” Disc
Do NOT insert the “Stand Alone Trailer Disc” into the DTS-6 with any movie disc.
This will cause the DTS-6 to malfunction. This disc is meant to be used when the DTS
and THX trailers are attached to a non-DTS feature. All current DTS movie discs
contain the DTS and THX trailers. To verify that these trailers are on your movie discs,
look to the right of the movie title. If it says “DTS Stand Alone Trailer” and “THX
Grand Trailer,” then the trailers are on the movie discs.
If you use the Stand Alone Trailer disc with a film not in DTS, add the trailer and insert
the disc into the DTS-6. Use of this stand-alone disc is for non-DTS films only.

• Starting Show
Less than a minute after power is turned on and the DTS movie discs are loaded, the
SYSTEM light will flash. This indicates the DTS-6 processor is ready for show start. If
the SYSTEM light does not flash, cycle the power on the DTS-6: turn unit off, wait 2
seconds, turn unit on. If the light does not flash after 40 seconds, turn off the DTS-6
unit, and contact DTS technical support. Call 800-959-4109 or [phone].
When DTS time coded film reaches the timecode reader head, the green light on the
timecode reader head and the TIMECODE light on the DTS-6 processor will illuminate.
A few seconds later, the DIGITAL light on the DTS-6 processor will illuminate and the
DTS digital sound track will start playing.
DTS recommends the show be pre-run. Check that the green timecode reader LED is
bright and steady, and the system performs properly. Check all reels for good time
code, if time permits. Occasional blink of the TIMECODE LED is normal. Go into the
theater and listen for good sound quality.
On current reader heads, the lateral adjustment screw has been covered. Do not
remove the sticker, this is factory set and there is no need of adjustment. On older
reader heads that do not have a sticker, you may adjust the lateral screw to achieve
maximum brightness of the green LED.
** Never adjust the lens on the reader head **

••
• Change-over
For those theaters that have two projectors, the DTS-6 processor will automatically
change over when first frame of picture timecode is read on the upcoming projector.
DTS digital 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-6 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.
