DTS-ECP Installation Manual Section 1, Introduction And Specifications

SECTION 1 INTRODUCTION AND SPECIFICATIONS

1.1. ABOUT THE DTS-ECP

1.1.1. How the DTS-ECP Works

The DTS-ECP is an expandable cinema processor that enables playback of motion picture
sound tracks. The standard unit combines the functions of a 6-track analog sound processor and
booth monitor. The unit is capable of audio playback in stereo optical (A-type or SR-type noise

reduction

), mono, and (stereo) NONSYNC formats. It also allows for automation interfacing and

playback of an external 6-track source. The unit has individual channel controls and emergency

BYPASS Mode. Individual channel EQ accomplished by the use of a laptop PC and DTS CP Setup

Software. The unit can be configured (via jumpers) for external or internal crossovers. WIDEBAND
is used for external and when internal is used, the customer specifies the resistor pack value
required. Other programmable (via jumpers) features include: Balanced or unbalanced external
NR, balanced or unbalanced output, screen loss EQ, and time alignment delay.

The unit is designed to be “expandable” meaning that DTS digital playback can be added as an
option. This option is added by installing the Model DPP.

1.1.2. Adding DTS Digital Upgrade (Model DPP, Digital Processing Package)

When the DTS digital package (Model DPP) is added, the following items are changed: Addition
of three CD-ROM drives, the front display is changed, software is changed, and the CPU board is
changed. A DTS timecode reader and cable will be issued as well as one reader for platter
systems and two readers (with ”Y” cable) for dual projectors (change-over systems).

Once DTS digital is added, the DTS-ECP uses DTS time-coded film to synchronize DTS digital
6-track sound (on DTS movie discs) to each frame of film projected. The DTS reader sends
timecode information on the film to the DTS-ECP. The DTS-ECP uses the timecode to play the
correct sound, on matching movie discs loaded into its CD-ROM drives, to the picture projected.
The projectionist simply inserts the movie disc(s) into the DTS-ECP and threads the film though
the DTS timecode reader. 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 (SR, A-TYPE, or MONO) which serves as a back-up sound source. If a
problem occurs in the DTS digital playback, the DTS-ECP switches out of digital and reverts to
the analog sound format that the film was recorded in. And at the end of the show, the DTS-ECP
automatically switches from DTS digital playback to

NONSYNC.

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. 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.

DTS-ECP Installation Manual Section 1, Introduction And Specifications

1.1.3. After DTS Digital (Model DPP) is Added

The DTS digital provides left, center, right, stereo surrounds, and subwoofer channels. The
system allows for play times up to 5 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.

DTS-ECP Installation Manual Section 1, Introduction And Specifications

1.2. DTS-ECP TECHNICAL SPECIFICATIONS (continued)

An external six-track analog input is available for a 300mV external source. The two status/control
connectors connect to theater’s automation system and to external digital playback systems for sense and
control functions. An external noise reduction loop connection is selectable for balanced or unbalanced
and can be fed into external noise reduction or to output another Lt/Rt signal such as magnetic print­master playback. Matrix may be disabled through software programming, for pure stereo playback.

The main output provides user selectable wideband or bi-amped outputs. Jumpers on D744 analog
board allow use of outputs for THX sound systems or speakers with built-in crossovers. If internal
crossovers are desired, plug-in resistor headers determine crossover frequency: 500Hz, 800Hz, and
1200Hz standard, other frequencies can be special ordered. Jumpers also select balanced or unbalanced
outputs for all channels, as well as screen loss compensation and time alignment delays for the screen
speakers.

Equalization for screen channels and surrounds is accomplished with laptop PC and DTS CP Setup

Software

in the digital domain along with both A-type and SR-type noise reduction. Three SP/DIF digital

audio pairs are available for left, center, right, subwoofer, and left & right surrounds.

B-chain alignment is easily accomplished via a laptop PC and DTS CP Setup Software (WINDOWSTM

based). Each channel has bass and treble control as well as third/single-octave EQ adjustments. Individual

output levels are set with trim-pots, and on-screen level adjustment allows SPL fine-tuning.

A-chain alignment is easily accomplished using test film, a laptop PC, and DTS CP Setup Software.
Separate solar cell adjustments are available for the two projector inputs.

Built-in booth monitor buttons select one or a combination of all six output channels, and are selectable
between DTS-ECP output and return from power amps. An additional button turns internal speaker
on/off. An external speaker connector is available on the rear panel (“MONITOR OUT”).

There is an overall master fader on the front panel and remote fader connections on the rear panel. Also
on the rear, is a remote front panel connection (

made for DTS E342, Remote Control panel).

A

NONSYNC source connector is available and its trim level is menu driven. NONSYNC signal routing can

be used for audio coverage when curtains are closed.

While in the

BYPASS mode, the signal from the solar cell is routed to the screen channels, and a separate

trimpot on the D744 board is used to adjust volume. A toggle switch (on the D744 board) can enable the

BYPASS mode. The DTS-ECP will also automatically go into the BYPASS mode if a fault occurs on CPU

or DSP boards. When BYPASS is enabled, a red LED (on the D744 board) lights to indicate the DTS-ECP is
in the BYPASS mode. The D744 board is located behind the control module on the front panel.

A universal fused power supply allows connection to all AC power sources. A standard power cord is
provided. An optional DC supply may be used via the “AUX POWER” connector and is used for
emergency backup power (

±12 VDC to ±15 VDC at 2 amps).

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

SECTION 2 INSTALLATION, JUMPERS, AND INTERFACING

2.1. INSTALLING THE DTS-ECP INTO THE SOUND RACK

DTS-ECP expandable cinema processor is designed to mount into a standard 19” wide sound rack. The
processor is 7" (4U) tall and 17" deep. Select a space in the sound rack where the processor will be at eye
level for most operators. Bolt the DTS processor into the rack. One rack unit of space should remain
open above and below the unit in observance of ventilation requirements.

• 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.

• 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.

• Check nameplate ratings to assure there is no overloading of supply circuits that could have an
effect on over-current protection and supply wiring.

• 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. Connect earth ground wire to #6 terminal provided on the DTS-ECP back panel.

• A quality surge / spike suppresser power strip is recommended to protect the DTS-ECP processor.

• Never block the side vents of the DTS-ECP. Free air flow within the unit prevents over-heating
and keeps dirt from being sucked in through the CD-ROM drives (when installed).

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

2.2. CONNECTING THE DTS-ECP

Refer to Section 9 Wiring Diagrams or Appendix A Pin-out Tables when making cables. Connections to
the DTS-ECP are made primarily via 9-pin or 25-pin “D” connectors, Phoenix and RCA-type connectors.

• Ensure that the DTS-ECP front panel power switch is in the OFF position.

• Lift off the display panel and verify that all three circuit cards are fully inserted.

The solar cell from the projector is connected to P5 “PROJ 1 OPTICAL INPUT”. If there is a second
projector, it is connected to P4 “PROJ 2 OPTICAL INPUT”. Connect a (DTS supplied) ferrite suppressor
around each cable going to a solar cell (on projector).

Main audio output is available at P2 “TO POWER AMPS”. This connector contains 12 output signals:
High and low frequency outputs for bi-amping each of the six channels. Installations with external
crossovers use the wideband (HF) outputs only (LF outputs are not used for wideband applications). The
D744 analog board jumpers must be set for either “bi-amp” or “wideband”. See Section 2.3

The internal crossover frequency is set by plug-in crossover resistor packs in D744. Consult speaker
manufacturer for crossover frequency requirement. See Appendix B for available resistor packs – these
must be removed if using unit in WIDEBAND mode.

To verify sound at the speaker amps, connect their outputs to P1 “MONITOR IN”. The enables the use of
the front panel monitor speaker and its selector switches. Wideband applications use P1 HF inputs only.

As the built-in monitor speaker is for reference only, it will be desirable to attach a self-powered
amplified speaker to the P3 “MONITOR OUT” RCA-type connector. The addition of an auxiliary monitor
speaker provides higher volume capabilities and better frequency response.

A NONSYNC source, such as a CD player, connects to P9A “NONSYNC L” and P9B “NONSYNC R” inputs.
These are RCA-type connectors and accept 300mV (line level) unbalanced signal. The NONSYNC signal
can be a normal stereo or matrix encoded source.

Timecode connectors are not used until the DTS Digital (Model DPP) is added.

Any six-track analog source at a 300mV can be connected to P8 “6-TRACK ANALOG IN”.

Format pulses from an automation system are connected to either P15 “STATUS/CONTROL A” or P16
“STATUS/CONTROL B”. Any of the six formats, mute, trim feature, or projector changeover can be
selected from this connector. These connectors also contain LED drive voltages for a remote front (or

status)

panel. NOTE: At this time, the RS422 connectors are not useable with digital automation.

P23 “HEARING IMPAIRED” output provides a center-weighted mix of the left, center, and right channels
for use with a hearing impaired sound system.

Connect the AC power cable to the DTS-ECP processor. (NOTE: The DTS-ECP processor is a computer
based system and as such can be susceptible to power line surges. A good quality surge and spike
suppressor made for computers is recommended). Two power supplies provide power to the DTS­ECP unit. Both supplies are fused and automatically adjust to incoming AC mains voltages: From 100
VAC to 240 VAC, between 50 and 60 Hz.

If using a DTS E342 remote front panel, connect it to P11A/B RS422 connector (either one).

If using a remote fader, connect it to P28 REMOTE FADER connector.

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

2.3. D744 ANALOG BOARD JUMPERS

Jumper Functions

Before powering the DTS-ECP, verify the jumpers on the D744 analog board are set for your
application. The D744 board is programmable (

via jumpers) for the following operations:

• Balanced or Unbalanced output for all six channels Surrounds and sub don’t use crossovers

• Wideband or Crossover output for all six channels for 5.1, are available for 6.0 operation.

• Screen loss compensation for Left, Center, and Right channels

• Time alignment delay for Left, Center, and Right channels

• Balanced or Unbalanced input and output for external NR connector

• Wake-up state of the booth monitor (Rev. J D744 boards use dip switch instead of jumpers)

Factory Settings

Unless specified otherwise, the DTS-ECP will be shipped with the following settings:

• Balanced Output

• Wide-band Output

• Screen Loss Compensation = OUT

• Time Alignment Delay = OUT

• Balanced Input and Output for External NR connector

• Booth Monitor Wake-up Mode:

* Left, Center, Right = On, Surrounds & Sub = Off

* AMPS = Off
* Internal Speaker = On

If any of the defaults are not the required configuration, change the jumpers accordingly. Use the
“Jumper Settings” tables in Appendix B or drawing on 2-7 to identify and change the correct jumper.

Changing the Jumper Settings

• Turn off the power. The DTS-ECP must not be powered when removing the boards.

• Remove the front panel by turning the thumbscrews counter-clockwise. Once the screws are

released from their sockets, the front panel can be removed and hung on the front of the chassis by
hooking its side catches to the two inside studs of the chassis opening. See drawing on page 2-4.

• There are three circuit boards behind the front display. The top board is the D744 analog board. It
contains the jumpers and crossover headers that the user can modify. The middle D741 board is
for Digital Signal Processing. The bottom D740 board is for CPU functions, stores software
memory, and contains the

RESET button. The middle and bottom boards require no adjustments

and contain no user serviceable parts. They should not be removed during setup..

• Remove the smaller of the two ribbon cables (24-pin) from the display. This cable is permanently
attached to the D744 board (top circuit board).

• The D744 board can now be removed by gently lifting the white levers on each side. You may
now gently slide the D744 board out from the chassis. Do not pull it out by the ribbon cable.

• To change D744 settings, use drawing on page 2-7 to find appropriate jumpers and crossover
headers. This information is also in Appendix B tables and charts.

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

What is behind the front panel

There are two RS232 ports on the DTS-ECP. One is located on the rear panel and the other on the

COMPORT panel, shown above. Both perform the same function of interfacing the DTS-ECP to a PC.

Using a null modem cable, connect the serial port of your PC to either the front or back RS232 connector.
Use one or the other, do not use both at the same time. After the DTS-ECP is fully booted, you may now

start the DTS Upload/Download program or the DTS CP Setup Software program on your PC.

The switch on COMPORT panel is selectable for front or back:
y Set to” back” when choosing to use the rear panel RS232 connector
y Set to “front” when choosing to use the RS232 connector on the

COMPORT panel

The “FRONT PANEL” cable connects to the front “CONTROL” panel.

The

RESET button on D741 is used to reboot the DTS-ECP.

NOTE:
* The DTS-ECP

D740-01 CPU board is not compatible with the D740 CPU board used on a DTS-6AD.

2.4. AUXILARY DC POWER SUPPLY CONNECTION

A separate 3-pin Phoenix connector is available for emergency power. A backup supply is highly
recommended for failsafe operation. The BYPASS circuits on the D744 board require voltage of
+12 VDC and –12 VDC to operate. If the internal power supplies fail, an external DC supply
that has both positive and negative output is required. It connects to the rear panel AUX POWER
P7A via a 3-pin Phoenix connector.

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

2.5. INTERFACING TO OTHER SOUND SYSTEMS/SOURCES (see WDE237, Section 9)

Automation Interfacing

The “STATUS/CONTROL” connectors are available for interfacing to automation systems.

External 6-Track

The 6-TRACK ANALOG IN connector, P8, on the back of the DTS-ECP, can receive any 300mV
50% modulation (85dB) analog sound source. Most common sources are from 6-track magnetic
print masters, other digital sound systems, and external microphones (with a mic preamplifier).

Reference input level is 300mV (each channel). The DTS-ECP master fader on the front panel
controls overall playback volume. There is no individual channel level adjustment for EXTERNAL.
Front panel “

EXT 6 TRK” button controls access to this sound source.

DolbyTM Model DA-20

The Dolby Model DA-20 is used to supply the Dolby DigitalTM sound track to the DTS-ECP. The
DA-20 audio output connects to the DTS-ECP “6-TRACK ANALOG IN”, P8, connector. It’s sense

control connects to one of the DTS-ECP “STATUS/CONTROL”, P15/16, connectors.

The DA-20 sense circuit requires that a rotary switch (in the DA-20) be set so that the DTS-ECP
will automatically switch to the sound format key used to access the Dolby DigitalTM input at P8.
In the DTS-ECP, this is normally the “EXT 6 TRK” button.

y In the DA-20, set the top rotary switch on the Cat. 611A “Cinema Processor Interface Card” to

setting 6 (CP45/65/500 Auto Digital Disabled). This is true for DA-20 units using new software.
This will allow the Dolby DigitalTM sound track to automatically switch in & out.

NOTE: DA-20 units with old software, should set rotary switch to setting 2 (CP45/65/500 Auto Digital).

y Set up the DA-20 using instructions in the DA-20 Manual. Use “Dolby Digital Test Film” to

test its operation with the DTS-ECP.

y See “External 6-Track Analog Source”, above, for more details.

External Crossovers

The DTS-ECP allows the use of external crossovers. When used, the D744 channel jumpers are
set for WIDEBAND, the crossover headers are open, and only the “HF” in/outputs are used.

Internal Crossovers

If internal crossovers are used, verify the value of the D744 crossover header resistors are
appropriate for the crossover frequency required by your speaker’s manufacturer. The D744
channel jumpers should be set for
speaker’s high frequency drivers may be compromised.

(continued)

BI-AMPED. NOTE: If the jumpers are set for WIDEBAND, the

DTS-ECP Installation Manual Section 2, Installation, Jumpers, and Interfacing

2.5. INTERFACING TO OTHER SOUND SYSTEMS/SOURCES (continued)

Remote Fader Option

A remote fader may be used to control the DTS-ECP overall playback sound. See SDE238 in

Section 9 for circuit details. The remote fader is enabled when P28, pin 3 is grounded.

(Auxiliary) Monitor Speaker

A self-powered amplified speaker can be used as an external monitor speaker. When connected, it
is always active. The

MONITOR buttons control which channels are listened to and the sound

source: From the amplifier or at the DTS-ECP output. For amplifier output, switch on the
“

AMPS” button. For the DTS-ECP output, the “AMPS” button should be switched off.

Digital Amplifiers

The SPDIF connectors: P25, P26, and P27 are used with digital amplifiers and speakers.

Digital Automation

Contact DTS for protocol specifications, Technical Notice E374.

External Microphone

An external microphone requires the use of a microphone preamplifier that delivers an output of

300mV. The output of the preamplifier may be fed into either P9A/B = NONSYNC L/R or P8 =
6-TRACK ANALOG IN. The master fader on the front panel controls playback volume. The
designated front panel button accesses the microphone input:

y P8 uses the EXT 6-TRK button
y P9A/B uses the NONSYNC button

NONSYNC

A NONSYNC stereo source of 300mV such as a CD or tape machine may be used on the DTS-ECP

A/B = NONSYNC L/R. Both connectors should be used. The NONSYNC output is controlled

at P9
by the

NONSYNC button. The master fader on the front panel controls playback volume.

NONSYNC signal routing to the surrounds is available via DTS CP Setup Software in Options,

“NONSYNC MODE”:

y Screen NONSYNC L heard screen left, NONSYNC R heard screen right
y Surround NONSYNC L heard in left surround, NONSYNC R heard in right surround
y Screen & NONSYNC L heard screen left and left surround, and NONSYNC R heard

Surround screen right and right surround.
y Matrix NONSYNC L and NONSYNC R signals are fed through the DTS-ECP’s

matrix decoder to derive left, center, right and surround channel outputs.
This mode should be used to playback material that has been matrix
(surround) encoded such as pre-recorded video tape.

2.5. INTERFACING TO OTHER SOUND SYSTEMS/SOURCES (continued)

External Noise Reduction

External Noise Reduction may be used for stereo or Lt/Rt signals. The EXTERNAL NOISE

REDUCITON

connection, P6, is selectable for balanced or unbalanced on the D744 via

programming jumpers. It can be fed into an external NR unit or be used with another Lt/Rt signal
from a magnetic sound print master. Matrix may be disabled via DTS CP Setup Software in

Options, “DISABLE MATRIX”. Highlight box to enable this feature.

DTS E342 Remote Front Panel (option)

Connect the DTS E342, Remote Front Panel, to P11A or P11B (“AUTOMATION”) connectors.
Once plugged in, both the remote and ECP front panels are active.

2.6. POWERING THE DTS-ECP, BOOT-UP SEQUENCE.

Once the DTS-ECP is completely connected to the automation and sound systems, the power
switch may be enabled. Once powered, the unit will progress through a boot-up sequence.

During the boot-up sequence, all the display LEDs will briefly illuminate, the BYPASS mode will
enable, the internal speaker will enable, and the drives will be checked (if installed). Once fully
booted, the DTS-ECP fader display should show a number and the NONSYNC format should be
enabled (this will occur unless the DTS CP Setup Software, automation, or remote front panel is enabling a

different format

).

The booth monitor “wake-up” state is set by a dip switches on the D744 board. See Page 2-7. If
the internal speaker does not enable or none/some of the AMP buttons enable, check the dip switch

settings. After the boot-up sequence, the internal speaker will remain enabled. The booth
monitor’s LEFT, CENTER, RIGHT, SW, INT SPK buttons should be illuminated (enabled). The
fader display should contain a number, as shown below. If the fader display does contain a

number, the DTS-ECP is not fully booted.
