RACK-MOUNTED INSTALLATIONS
If this product is installed in a closed or multi-unit rack assembly, the following items must be
considered.
1.
The ambient temperature within the rack may be greater than room ambient temperature. The
maximum temperature for the equipment in this environment is 50°C. Consideration should
be given to the maximum rated ambient.
2.
Installation should be such that the amount of air flow required for safe operation is not
compromised, and that a hazardous condition is not achieved due to uneven loading.
3.
Check nameplate ratings to assure there is no overloading of supply circuits that could have an
effect on overcurrent protection and supply wiring.
4.
Reliable grounding of this equipment should be maintained. Particular attention should be
given to supply connections when connecting to power strips, rather than direct connections to
the branch circuit.
5.
A quality surge / spike suppressor power strip is recommended to protect the DTS-6
processor.
SYSTEM CONSIDERATIONS
A DTS digital playback system can place enormous demands on the amplifiers and speakers in your

Section 1: Introduction
INTRODUCTION
The DTS digital sound process for motion pictures is designed for the digital sound release of
motion pictures in 6-track theaters. It is a dual system in that the digital audio data is recorded on
CD-ROM discs. A special DTS timecode is printed on the motion picture print along with a
conventional stereo optical soundtrack. The timecode is used by the DTS system to synchronize
the sound and picture. The timecode lies between the picture and optical sound track, and is
printed onto the release print from the soundtrack negative. There is a single inventory of prints.
The DTS-6 system provides left, center, right, split surrounds (or mono surround) and subwoof
channels. The systems allow for play times up to 3 1/3 hours. They are completely automatic
and fail-safe in operation requiring no action by the projectionist. The systems automatically
start and stop, and track film breaks and change-overs. The digital audio data is sampled at
44.1K samples per second. APTX100 digital audio data compression (4:1) is used. Transfer into
the process can be made from conventionally mixed analog or digital sound masters.
How Does the DTS-6 Work?
Using DTS timecode printed on the motion picture film, the DTS-6 system (with matching
movie discs loaded) reads the timecode and plays the correct sound for each frame of film
projected. The projectionist inserts the movie disc(s) into the DTS-6 and threads the film though
the DTS timecode reader head. Once the film is started, the DTS system checks a keyed serial
number in the timecode and on the movie disc(s) to assure the correct sound is being played with
the movie being shown. Films released in the DTS digital sound format also contain a traditional
analog (optical) sound track (either “SR” or “A” type) which serves as a back-up sound source.

Section 3: Installation Procedure
INSTALLATION PROCEDURE
The DTS system consist of two major components: Q DTS Timecode Reader Head and
R DTS-6 processor (player). The following is a generic procedure intended to supplement the
processor installation wiring diagrams for specific manufacturer's sound systems. Look for these
diagrams in Section VIII.
3.1
Timecode Reader Head Installation
•
The Timecode Reader Head is designed to be mounted onto most projectors with a single
mounting bracket.
•
Position the appropriate DTS mounting bracket on the same bolt pattern as the reel arm
and bolt securely in place (see “bracket mounting diagrams,” in Section VIII).
•
Install the Timecode Reader Head onto the DTS mounting bracket and bolt into place
with supplied hardware.
•
Reinstall the reel arm on the top bolt pattern of the DTS mounting bracket.
•
Align the DTS mounting bracket and the reel arm.
•
The DTS timecode reader MUST have a straight film path (no angles or twists) and at
least a small amount of tension. The auxiliary flanged roller on the timecode reader head
is used to avoid film “walk out” and helps to stabilize the film. Additional guide rollers
may be added to ensure proper film tension - most critical on platter systems.
•
Connect the 9-pin timecode cable and route to the sound processor rack for interconnect
with the DTS-6 processor.
•
Two projector (change-over) theaters
Be sure to place each reader head at the same place on the projectors. The offset value
must be the same for the movie to play in sync at both projectors.

Section 3: Installation Procedure
DTS-6 Processor Installation
DTS has configured your DTS-6 processor to interface to the cinema processor as indicated
on the packing list. A DTS-6 labeled “generic” will be set for stereo surrounds, subwooferdisable turned off, and platter (single projector) operation. If the DTS-6 processor you are
about to install did not come from the factory then you will need to check some internal
switches.
** Be sure the rear panel AC voltage switch is properly set for your mains
AC supply rating **
Remove the top cover. See Figure 1.
Programming the Surrounds
The transformer board, D426, that is mounted to the left of the unit must be set for either
split surround or mono surround operation. Current boards have toggle dip switches near
the top of the unit. Toggling all these switches up is for split surround and toggling
them all down is for mono surround operation. If your transformer board does not have
dip switches then there are three shunts that have to be set. All three locations are clearly
marked split or mono. Place the shunt over the middle pin and split pin for split surround
operation, or the middle pin and mono pin for mono surround operation. See D426
transformer card diagram for details.
Programming the Subwoofer Output at the Stereo Cable
Locate the playback card D420 REV E (the card with the 15-pin D-connector on rear
panel). To ensure the subwoofer signal always appears at the stereo cable:
- DTS-6 units with serial number 2000 or over, set both dip switches at the top of the
board (S1) to the following: S1-#1 OFF (open) towards the board and S1-#2 ON
(closed) away from the board. Setting S1-#1 ON will cause the subwoofer signal to not
appear at the stereo cable. S1-#2 is no longer used.
- DTS-6 units with serial number 1000 or under, be sure no shunt appears across J6.
Putting a jumper across J6 will cause the subwoofer signal to not appear at the stereo
cable.
Programming for Change-over Operation
Locate the timecode board D422 (the card with the 9-pin D-connector on the rear panel
and LED's on the front). Near top center of the board there is a 7-position header. A
shunt is required vertically over position “0” (farthest right position) if you are installing
for change-over operation. Remove this shunt for platter house operation.
Reinstall top cover.

Section 3: Installation Procedure
The DTS-6 Processor
•
The DTS-6 processor is designed to be integrated into your existing theater sound system
without affecting normal theater operation. All interconnects are stand-alone. No cuts or
jumpers are necessary on most systems.
•
DTS-6 processor requires 5 1/4" tall by 17" deep of 19" wide rack space for proper
mounting. Select a space in the sound rack not more than three feet from the existing
*cinema processor to be interconnected. Bolt the DTS processor into the rack. Be sure to
observe ventilation requirements specified in the beginning of this book.
•
Check that the DTS-6 front panel power switch is in the OFF position.
•
Connect the power cable to the DTS-6 processor. (NOTE: The DTS-6 processor is a
computer based system and as such can be susceptible to power line surges. A quality
surge/spike suppresser made for computers is recommended.
•
Connect the 9-pin cable (P/N D435) from the timecode reader head to the back of the
DTS-6 processor.
•
Refer to wiring drawings in Section VIII that relates to your specific installation. Connect
the DTS-6 50-pin cable (P/N D434) into your cinema sound system / processor.
•
The 15-pin “stereo” cable is used for some installations. It is used to route the DTS-6
subwoofer output to the subwoofer amplifier. It is used with the Dolby CP200, CP55,
and some UltraStereo processors. Other cinema processors use the other DTS subwoofer
output at the 50-pin connector (JM21). See Section VIII “Wiring Diagrams” and find the
diagram that pertains to your installation.
•
You may connect the DTS-6 into other digital playback sound systems. You may obtain
the necessary adapters from DTS.
-- for a CP200 with SR-DTM, use the D462 cable
-- for a CP65 with SR-DTM, use the D462-01 cable
-- for a CP500, use the D561 cable and the D715 board.
See Section VIII “Wiring Diagrams” for installation details.
REMEMBER
** Be sure the rear panel AC voltage switch is properly set for your main AC
supply rating **

Section 4: Checkout and Adjustment
CHECKOUT AND ADJUSTMENT PROCEDURE
A SPL meter and the DTS technician’s kit (not included with the DTS system) are required to
complete the checkout and adjustment procedure. The technician’s kit consists of:
- a DTS 6-track Rev. DS1 (or C) Setup disc (to adjust DTS-6 levels)
- the DTS BUZZ AND BILL SHOW disc (to test the DTS system), dated Feb 1, 1999
- the DTS Demo film (used with the BUZZ AND BILL SHOW disc)
- a DTS Empirical test disc (to test the theater’s sound system), dated June 7, 1997
- a DTS trimpot tweeker
- a DTS T-shirt
4.1
Setting SPL (Sound Pressure Level)
The theater sound processor’s B-chain should be checked and adjusted before the DTS system is
installed. Any changes to the B-chain will effect the output levels on the DTS system.
Introduction
The output levels are factory preset at 250mV rms. This nominal level will insure that speakers
will not be overdriven during the setup procedure. If the DTS-6 processor you are about to
install has come from another theater installation, be sure to turn down the level trimpots (CCW)
before proceeding to guard against accidental overdriving of speakers.
Subwoofer
The DTS subwoofer output level ranges from 20Hz to 80Hz, up to 27dB above reference
(112dB). You must observe your subwoofer’s specifications to avoid damage to the speaker.
If a subwoofer is driven below its cutoff frequency, its driver(s) may become unloaded. When
unloaded, the voice coil can travel outside of the magnet’s gap, thus overheating or causing
mechanical damage to the speaker. A high pass filter should be installed on those speakers with
high cutoff frequencies. Contact your speaker manufacturer for more information.
Setting DTS-6 Levels
Turn power on and insert the SETUP DISC (mentioned above). After a delay of about 40
seconds, the SYSTEM light will blink, then the DIGITAL light and the CD-ROM light will illuminate
and the cinema processor will change to digital format. Tone should be heard in the theater.
Open the screen curtains. Go into the theater to make SPL readings in the rear third and just offcenter of the room. Do not simply point the sound pressure level meter out of the port hole
window. This will not give you accurate SPL readings. See the next page for SPL level settings.

Remove the blue cover by unscrewing the two black Philips screws from the front panel. With
ALL power amplifiers turned on, master fader set to reference position “7” and speakers
unmuted, adjust the appropriate “6-TRACK” trimpots on the DTS-6 processor (see Fig 3) to
achieve the specified SPL noted above.
MONO SURROUND
For those theaters with mono surround only, wait for either the left -or- the right surround PINK
noise when adjusting the MONO SURR trimpot for 82dB SPL. Be sure the surround switches
inside the DTS-6 player are set for MONO. See Section 3.2.
NOTE: The STEREO adjustment trim pots are no longer used.
• Index Switch
On some models, there is a small black momentary push button switch located below the
TIMECODE HEAD OFFSET switches (Figure 3). It is commonly called the “index switch”. This
button can be used to increment to the next track being played. This feature works on the DTS
6-TRACK SET UP discs Rev. D and Rev. C only. On shows of serial number 1009 and higher,
the momentary button also bypasses the DTS-6 processor to allow checking of the optical bypass
function.
If your DTS-6 does not have an index switch and you’d like to install one, call DTS and purchase
the D475 kit. This kit has all you need to install the index switch to your DTS-6.
• Automatic Default programming
There are only two choices on the DTS-6 unit: A-Type or SR-Type. The programming is
accomplished via jumpers on DTS external logic boards. See wiring diagrams for more
information.

Timecode Reader Adjustment. See Figure 4.
•
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 you do not have a DEMO REEL, you can still set the offset switches 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
EXAMPLE: 27 frames X 1.25 = 33.75 - 1 =
HEAD OFFSET switches to this number.
32.75 offset. Round this number off to the next whole number. So, “33” would be your
offset number.
REMEMBER: If you use the counting frame method, frames are counted from the timecode
reader lens to the picture aperture. If you are 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:
Be sure to make the same size film loops inside the projector when
measuring the offset as you do when running a movie. Failure to do so will result in
improper sync when the movie runs in DTS.
•
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 you are
a change-over theater, run 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-6 level settings.
- Remove the business card and verify the cinema processor switches back to digital
format within six seconds.

Section 5: Operation
OPERATION
• Threading Timecode Reader: Refer to Figure 5. Make the same size loops through
the projector as you did when checking the offset number.
• Verifying Movie Discs
Make sure your discs match the movie (e.g. “Jurassic Park” film with “Jurassic Park”
movie discs). If the film and discs don't match the digital sound track will not play.
For movies running over 90 minutes, you should receive two movie discs: one labeled
6-track A and another labeled 6-track B. The two discs can be inserted into the
drives in any order.
For movies running at or under 90 minutes, you should receive one movie disc. These
movie discs will be labeled “one disc only”. You may place the single disc into either
drive. Do not put any other disc in the remaining drive.
A disc labeled STEREO will not play properly in your system.
• Loading Discs into the DTS-6
Turn power on. Press the eject button of both drives to remove any discs that may be
left in the drives. Any discs present will eject after 3 seconds. Remove the old discs
from the drives. Open drive door, and slowly push the new CD-ROM (in caddie) into
drive. When about 1/2 inch of caddie is left sticking out of the drive, the drive will
automatically pull in the disc. Do not eject any disc from the DTS-6 while playing in
digital as it will cause the unit to reset.
IMPORTANT: Whenever discs are changed from one movie to another, eject the old
discs, insert the new discs, wait for discs to seat, turn power off, wait 2 seconds and
then turn power on.
• Before The Show
Remember to add the DTS trailer (logo) film to the head of the DTS encoded movie.
Cut the trailer at about six frames after fade-out (should still have timecode) and splice
directly to the first frame picture (of the movie) with timecode.
• Fader Setting
Most faders should be set to “7”. This may be readjusted for best play in your theater.
NOTE: In some theaters, the subwoofer will not change with the fader.

Section 5: Operation
• 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 (818) 706-3525.
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.

DTS-6 Installation Manual
Section 5: Operation
• Maintenance
The timecode reader lens should be blown off with compressed air once a day to
remove any dust build up. The CD-ROM drives do not have to be cleaned, but keep
their doors shut as to keep dust out.
• 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 system must be configured for the type surrounds (mono/stereo) present in
your theater. Since the player’s top cover must be removed to change the settings,
check this before putting it into the rack. To check or change the DTS-6 surround
programming, see Section 3.2.
* The DTS-6 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. See Section 4.2. Change-over houses must attach the reader
heads at the same place on both projectors so their offset numbers match.
* The DTS-6 level pots must be recalibrated for its new location. Using a sound
pressure level meter and a DTS 6-track setup disc, 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-6 unit will result in
improper playback levels.

DTS-6 Installation Manual
Section 5: Operation
• How DTS Effects other Cinema Processors
Dolby CP200 Operation
The automation should set the CP200 processor’s optical default to either “04” A-type
or “05” SR . When the DTS switches to digital, the normal signal paths of the CP200
are interrupted. The DTS-6 signals will be inserted just prior to the CAT64 EQ cards,
in effect taking over the CP200. When the DTS-6 switches out of digital, the CP200 is
released to function as normal and default to the format previously selected.
Unless modified, the CP200 does not have a subwoofer input. DTS normally inserts its
subwoofer signal after the CP200. As a result, the subwoofer level will not be effected
by the fader or mute.
Dolby CP55, CP65, CP500, and UltraStereo JS Operation
The DTS-6 will automatically pulse the audio processor to the digital format when it
starts to play a digital sound track. Whenever the DTS-6 drops out of digital, a pulse
will be sent to switch the audio processor back to the optical format. On units equipped
with a DTS D490, D496, or D497 logic board, the pulse to switch back to optical will
be blocked if the audio processor is not in the digital format. Example, if the
automation switches to non-sync, the DTS-6 will not switch back to optical. The DTS
D490, D496, and D497 logic boards also have a jumper which is used to select between
A-type or SR as the fall-back format.
The DTS-6 will only pulse the audio processor into the digital format when it first
switches to digital. After the show has started (or the show is re-started after a film
break) make sure the automation doesn’t switch the theater processor back out of the
digital format. Set the automation/cues so no audio format change takes place after the
DTS has switched into digital. Switching to nonsync at the end of the show is OK.
Dolby CP500
*
*
*
Must have the Cat. 685 (analog input card) installed.
JM21 on the DTS-6 50-pin cable uses the DTS D561 (interface cable) to connect to the “6 CH.
INPUT” on the CP500. Format 11 is normally used to access this connector.
The DTS D715 (logic card) interfaces DTS BS22 (on 50-pin cable) and connects to the
“AUTOMATION” connector on the CP500. Logic for Format 11 is already programmed in on stock
units from Dolby.
Dolby DA10 / 20 SR-DTM System
The DTS-6 can be connected to the Dolby SR-DTM system without effecting its
performance. The DA20 connects to the DTS-6 JM11 connector through a special
adapter, *D462. When the DTS-6 is off, the DA20 output is routed through the DTS-6
from JM11 to JM21. When DTS is on and playing in digital, the DA10 / 20 connection
(to the cinema processor) is broken inside the DTS-6 (via relays) and the DTS digital
sound track comes out of JM21. SR-D should be powered down when playing DTS.
* Use the DTS D462-00 adapter with the Dolby CP200
* Use the DTS D462-01 adapter with the Dolby CP65
Sony SDDSTM
The DTS system does not effect nor connects to the SDDSTM system.

• D-426 TRANSFORMER BOARD
See drawing D426. Located on this board is the 50-pin output connection,
transformers, relays, and split/mono surround switches. Output of all channels leave
from this card. Subwoofer is also carried on the “stereo” cable.
The newest boards have three dip switches, all grouped together and located towards
the top and rear of the board. These dip switches are either all up for stereo or all down
for mono surrounds.
Older boards had three shunts to change to split or mono surround. All three shunts P1,
P2, and P3 are clearly marked split or mono. The shunts are not grouped together, P1
and P2 shunts are located near the top rear of the board. The P3 shunt is located at the
front of the board just next to the first transformer towards the top. It is not necessary
to remove the board to change shunt positions, but using needle nose pliers will make
it easier to grab them securely.
• D-421 MEZZANINE BOARD
The D-420 and D-421 come as a set. The D-420 board is the larger of the two and as a
set, both boards provide audio for all channels. Located on this board are the stereo
pots, S1 dip switch, fuse, and stereo output connection. The stereo pots on the front of
the card are no longer used, with the exception of the very bottom one marked 6-track
subwoofer.
There is a dip switch marked S1, which is located on top of the board about 3” back
from the front. This switch controls both the subwoofer-out relay and (stereo) DTS-in
relay. Since the stereo format is no longer used, the proper setting of this switch is #1
off and #2 on. If the dip switch is not marked, on is away from the circuit board and off
is towards the circuit board. The fuse is for the 5V output on the stereo cable.
• D-420 PLAYBACK BOARD
See drawing D420. The D-421 and D-420 come as a set. The D-421 is the smaller of
the two and contains the logic control. Located on this board are the 6-track channel
SPL adjustment pots.

Section 6: Troubleshooting
• D-422 TIMECODE BOARD
See drawing D422. This board has the timecode head offset switches, the four system
status LED lights, a 7-position programming header, a 15-pin time-code cable output
connector, an EPROM chip, a ROM-DOS chip, an indexing switch, and 5V fuse.
- The OFFSET switches are adjusted according to the timecode reader location. This setting is
different depending on type of projector or location of the timecode reader. Determining the
offset setting is done with either frames count method or using the DTS leader from the
Demo Film.
- The status LED lights: SYSTEM light flashes when the DTS-6 is ready to play, TIMECODE
lights if good timecode is being read, DIGITAL lights when the DTS-6 is playing in digital,
and CD-ROM lights if the drives are recognized and the discs are being read.
- The 7-position header has jumper settings for different functions, most common is the setting
for single projector operation. For this, the jumper is in a holder position which is across top
part of the header, set horizontally between the “4” and “0”. For dual projector operation
the jumper is set vertically on the “0” position.
- The 15-pin connector is there for the “stereo” cable to plug into. The stereo cable is currently
being used for subwoofer output only.
- The EPROM stores part of the operating software information while the rest is on the movie
disc(s).
- The ROM-DOS is located near the center bottom of the board When updating the CD-ROM
drives from 2X to 4X, the ROM-DOS chip has to be replaced to Rev. C. When replacing
with TEAC drives, contact DTS.
- The index switch, located below the offset switches, can be used to advance though the
individual channel pink noise tests on the DTS “REV C” Setup Disc. It can also be used to
force the DTS-6 (when playing in digital) to optical for as long as the button is held down.
- The 5V replacable fuse protects the power going to the DTS timecode reader head.
• POWER SUPPLY - Supplies power to the DTS-6 unit. Caution, be sure to check
that the proper AC voltage is selected on the supply for your installation.
• SCSI BOARD - Controls the CD-ROM drives.
• CD-ROM DRIVES - There are two CD-ROM drives in the DTS-6. Both are the
same with exception of the way top and bottom drive program jumpers are installed and
if terminating resistors are added Contact DTS for more information.
The lights on the two CD-ROM drives will flash when the drives are recognized during
the test cycle (after power-up) or when the movie discs are being read.

EXTERNAL CABLE ASSEMBLIES
• 6-Track Cable Assembly - D434
The 6-track cable is broken into three parts: JM11, JM21, BS22. The white dot on
plugs indicate pin 1.
- JM11 is used as an input from other sound sources (such as the CP200 pass through)
to the DTS-6. This includes other digital sound sources such as Dolby SR-DTM.
- JM21 is used as an output from the DTS-6. When the DTS-6 is playing in digital,
only the DTS-6 output appears at JM21. If the DTS-6 is powered off or if it is not
playing in digital, then any signal fed into JM11 appears at JM21, and if no signal is
fed into JM11, then no output will be seen at JM21.
- BS22 is used to control some logic circuits on cinema processors.
• Stereo Cable Assembly - D436
The stereo cable is currently being used for only subwoofer output to some cinema
processors. A relay built into the DTS-6 will pass the analog subwoofer or play the
DTS subwoofer.
• Timecode Cable Assembly - D435
This cable connects the DTS Timecode Reader Head to the DTS-6 Processor. On
single projector (platter) systems, this cable has a single connector at both ends. For
dual (change-over) projector systems, this cable has a single connector at one end and
two connectors at the other end. See D477 for assembly diagram.
EXTERNAL BREAK-OUT BOARDS
• Generic Logic Break-out Board - D431 - Connects to BS22 on D434 if a “special
logic” board is not used.
• Special Logic Break-out Boards
These boards are used to block the pulse that selects the optical format when the
processor is in nonsync. You may select the default format to SR or A-type. These
boards are used with the following cinema processors:
- D490 is used with the Dolby CP55
- D496 is used with the Dolby CP65
- D715 is used with the Dolby CP500
- D497 is used with UltraStereo
• Audio Break-out Boards
- D437-00 is our generic audio breakout board. Wires must be soldered to the board for
connections to the cinema processor. Has no spade lugs. Generally used for testing
the audio output from the DTS-6.
- D437-01 is used with the Dolby CP55 and CP65. Has spade lugs which are intended
to slide under the terminal strip of the cinema processor.
- D458-00 is used with the Dolby CP50. See D459 wiring diagram for connection.
- D458-01 is used with the Dolby CP100. See D460 wiring diagram for connection.
- DTS10B is used to attach the DTS-6 to UltraStereo processors.

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.
6-13
DTS-6 Installation Manual
Section 6: Troubleshooting
• Switches out of DTS digital (continued)
- If the TIMECODE LED on the DTS-6 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 blinking and maintains a steady glow, this indicates that
you need to add more tension. Tension is added by repositioning the auxillary flanged
roller on the reader head so that it has maximum contact with the film or by adding
additional rollers. Verify all the gears in the projector are in good condition.
- If the reader head does NOT have a sticker on the largest roller and the LED is not
bright or is blinking, adjust the lateral screw which is located in the center of the
reader head's largest roller. Turn the screw slowly one way, and if the LED does not
brighten, turn slowly the other way until the LED is on steadily.
- Use compressed air to blow off the reader head's lens, but never adjust the lens.
- If the reader head DOES have a sticker on the largest roller, do not disturb the sticker
on the reader head and do not adjust the lens. Make no adjustments on this style
reader head (unless directed by DTS engineers).
- Attach the grounding jumper on the timecode cable to the projector. Easiest place to
do that is attach to the screw that secures the timecode cable to the reader head. The
reader’s housing must be electrically connected to the projector housing. Verify with
an ohm meter. This is needed for projectors that are not properly grounded.
- If the drop-out occurs during the same place(s) in the movie, replace the reel(s).
- If you are a platter house - turn off the DTS-6 unit. Take the unit out of the rack and
open the lid. Look inside at the timecode card (one with the LEDs). Be sure the
jumper is positioned horizontally across the top row of W1. The jumper should not
be installed vertically.
- Remove any sound format cues that appear after the DTS timecode starts. Or contact
DTS engineers for assistance.
- Last resort is to force the unit to play in optical. Turn off the DTS-6 unit. Be sure the
cinema processor switched to optical, if not manually select. Call your theater
technician who should contact DTS engineers.
• What do I do with the discs when the movie has finished its run?
Simply return the movie discs with the film to the depot. Put the discs in the DTS
yellow reel and load it into the film can.

DTS-6 and DTS-6D to Dolby CP650 Using the D715 Logic Interface Board
! DTS D715 operation with DTS-6D (3-drives) and Dolby CP650
Connect D715-J18 to the CP650 “AUTOMATION” connector. A 25-pin cable connects the DTS-6D
AUTOMAION to D715 on J1. If using the CP650 remote fader, use the DTS E322 extender to lift
D715 away from the rear panel and give clearance to the remote fader connector.
D715 board: W5 and J2 are used only for DTS-6 applications and J6 is a pass-through connection
for automation.
When the DTS-6D switches into digital, it sends a format pulse to the CP650 “AUTOMAION“
connector on pin 5 (Format 11 “external 6-channel analog” = DTS) which engages button “11” on the
front panel.
When the DTS-6D drops out of digital, it will send 1 of 4 (fallback) pulses to the CP650. The D715
logic board has jumpers that “steer” each default pulse to one of several CP650 format keys.
The MONO, A-TYPE (“A”), and SR pulses are sent by the DTS-6D. They are programmed on the
DTS movie disc(s) and are used to return the CP650 back to the optical format the movie was
recorded in. The NONSYNC (“NS”) pulse (from the DTS-6D) will be sent if DTS timecode is lost
during the last 60 seconds of the last reel.
SETTING FORMAT JUMPERS
MONO jumper
NS jumper
SR jumper
“A” jumper
- place jumper horizontally across SK1 (‘01’ button)
- place jumper between center pin and SK7 (“NS” button)
- place jumper between center pin and SK3 (“05” button)
- place jumper between center pin and SK2 (“04” button)
! DTS D715 operation with DTS-6 (2-drives) and Dolby CP650
Connect D715-J18 to the CP650 “AUTOMATION” connector. The DTS-6 “BS22” 10-pin connector
(on the 50-pin cable) connects the DTS-6 logic to D715 on J2. Note pin 1 for proper orientation. If
using the CP650 remote fader, use the DTS E322 extender to lift D715 away from the rear panel and
give clearance to the remote fader connector.
D715 board: J1 is normally used only for DTS-6D applications and J6 is a pass-through connection
for automation.
When the DTS-6 switches into digital, it sends a format pulse to the CP650 “AUTOMAION“
connector on pin 5 (Format 11 “external 6-channel analog” = DTS) which engages button “11” on the
front panel.
W5 must be installed for “fallback” operation (use jumper from “SR” or “NS” header) with the DTS-6.
When W5 is installed and the DTS-6 drops out of digital, a single “fallback” pulse will be sent to the
CP650. The D715 board’s “A” 3-pin header “steers” the pulse to either SK2 (A-TYPE = “04” button)
or SK3 (SR = “05” button). The user must select which format is desired and selection is made with a
jumper from the center pin to the optical sound format the movie was recorded (most cases = SR).

TECHNICAL UPDATE FOR DTS TO DOLBY CP-55 / WITH AUTOMATION
At the end of the show when the automation pulses the processor to non-sync it will occasionally switch
back to 04 optical causing the tail end of the film to be heard as it runs out of the projector. To prevent this
from occurring it will be necessary to replace the small board D-431.
READ INSTRUCTIONS AND SEE ILLUSTRATION BEFORE MAKING ANY MODIFICATIONS
The d-431 board is connected between the BS-22 ribbon cable and the CP-55. NOTE: on some 50-pin
cables the BS-22 ribbon cable is soldered directly to the D-431 card. If this is the case you will need to cut
the ribbon cable removing D-431 and then install the enclosed 10-pin strip IDC socket which will plug into
the new D-490 card.
The new D-490 card has an additional feature, if your CP-55 is equipped with an SR unit it can be wired in
such a way that you may select SR or A-type format back-up. This can be done by moving the jumper
located on the new D-490 card J2 across pins 2 & 3 for A-type or across pins 1 & 2 for SR.
An optional remote switch can be installed and labeled on front on the rack for more ease of setup and
eliminate the need of moving the jumper.

TECHNICAL UPDATE FOR DTS TO DOLBY CP-65 / WITH AUTOMATION
At the end of the show when the automation pulses the processor to non-sync it will occasionally switch
back to 04 optical causing the tail end of the film to be heard as it runs out of the projector. To prevent this
from occurring it will be necessary to replace the small board D-431. This new card also features a
selectable “SR” or “A” type back-up switching feature. In addition the new card will accept the SR-D sense
control plug.
To install the D-496 board on the CP-65, remove the cover off the J-18 pin connection on the back plane.
Plug the new card directly into the J-18 socket of the CP-65. Plug the SR-D sense control into conn 2 of the
new board. (If you are equipped with SR-D) If you are not equipped with an SR-D unit simply cover conn
3 with the cover that was removed from the back plane of J-18. Next remove DTS cable BS-22 from old
logic board D-431 and install cable on conn 3 of the new board. *Note on some 50 pin cables the
BS-22 ribbon cable is soldered directly to the d-431 card. If this is the case you will need to cut the ribbon
cable removing D-431 then install the enclosed 10-pin IDC socket which will plug into the new D-496
board. Make sure BS-22 is plugged in correctly. See diagram.

Dual Projector Theaters
Guide For A Seamless Change-Over
Occasionally, when running a DTS movie with dual projectors, you may come across situations
when the picture and sound are not changing in unison during a change over. This is due to the
fact that as soon as the first frame of action reaches the picture aperture on the incoming
projector, the DTS digital sound will change over to that reel. DTS digital sound changes
independent of the projector’s dowser position. Change over anomalies are most evident on
movies that have very tight editing / scene change tolerances from one reel’s end to the next
reel’s start.
Since every brand of projector has variances (speed, for example), you may come across
occasions when, during a change-over, the picture and sound are not changing at the same time.
When this occurs, do the steps below.
Sound changes before picture
When threading the incoming projector, roll down the film to a greater number of feet. If you
normally thread to “8", try threading to “9" or “10”. Keep adjusting the roll down setting until the
picture changes with the sound. Also, try hesitating a second before starting the incoming projector
on the first cue.
Picture changes before sound
When threading the incoming projector, roll down the film to a lesser number of feet. If you
normally thread to “8", try threading to “7” or “6". Keep adjusting the roll down setting until the
picture changes with the sound. Be sure to hesitate opening the dowser on the incoming projector
(on the second cue) until the last word on the outgoing reel is heard on screen.
Determining roll-down
Adjusting the roll down setting is a judgment call. Base it on the time delay of picture vs. sound.
One second of delay equates to 24 frames, or 1.5 feet.

Notice to Field Technicians
Subject:
UltraStereo Interface to DTS-6
July 24, 1995
A problem has been identified in the UltraStereo DTS-10B board.
The UltraStereo audio breakout board, DTS-10B, has the left surround and the mono surround
outputs tied together. This lowers the left surround’s output level and rolls off its high end when
the DTS-6 is set for split (stereo) surrounds.
Only the DTS-10B (shown below), WITH NO REV. LETTER, requires modification. Boards
marked with a yellow dot have been reworked by DTS.
If you have a DTS-10B board that has no Rev. letter, do the steps below:
1)
Unplug the JM21 ribbon cable connector from the DTS-10B board. Remove the DTS10B board from the back of the UltraStereo processor.
2)
On the DTS-10B board, cut off pin 18 (as shown). Cut the pin as close to the board as
possible.
3)
Reconnect the DTS-10B board to the UltraStereo processor and the JM21 connector.
4)
Recalibrate the left surround SPL level using the DTS REV. D (or Rev. C) SETUP DISC
or DTS EMPIRICAL TEST DISC. See Section IV, “Setting the DTS-6 Levels”. Verify
all channels have proper SPL settings.
Please direct any questions about this modification to DTS Field Services (800) 959-4109.
