READ INSTRUCTIONS - All safety and oper-

ating instructions should be read before the
DTT2500 Digital amplified subwoofer/sat­ellite system is operated.

RETAIN INSTRUCTIONS - The safety and

operating instructions should be retained
for future reference.

HEED WARNINGS - All warnings on the

subwoofer and in the operating instruc­tions should be adhered to.

FOLLOW INSTRUCTIONS - All operating

and use instructions should be followed.

CLEANING - Unplug the Power Supply

Adapter from the wall outlet or other power
source before cleaning. Do not use liquid
cleaners or aerosol cleaners. Use a damp
cloth for cleaning.

ATTACHMENTS - Do not use attachments

not recommended by Cambridge
SoundWorks as they may cause hazards.

WATER AND MOISTURE - Do not use the

Decoder Amplifier near water—for ex­ample, near a bath tub, wash bowl, kitchen
sink, or laundry tub; in a wet basement; or
near a swimming pool; and the like.

ACCESSORIES - Do not place the DTT2500

Digital Decoder Amplifier on an unstable
cart, stand, tripod, bracket, or table. The
Decoder Amplifier may fall, causing seri­ous injury to a child or adult, and serious
damage to the product. Use only with a
cart, stand, tripod, bracket, or table rec­ommended by Cambridge Sound-Works,
or sold with the product. Any mounting of
the satellites or subwoofer should follow
the manufacturer’s instructions, and

should use a mounting accessory recom­mended by Cambridge SoundWorks.

VENTILATION - Slots and openings in the

Decoder Amplifier are provided for venti­lation and to ensure reliable operation of
the Decoder Amplifier and to prevent it
from overheating. These openings must
not be blocked or covered. The openings
should never be blocked by placing the
product on a bed, sofa, rug, or other simi­lar surface. The Decoder Amplifier should
not be placed in a built-in installation such
as a bookcase or rack unless proper ven­tilation is provided or Cambridge
SoundWorks’ instructions have been ad­hered to.

HEAT - The Decoder Amplifier should be

situated away from heat sources such as
radiators, heat registers, stoves, and other
products (including amplifiers) that pro­duce heat.

POWER SOURCES - The Decoder Amplifier

should be operated only from the type of
power source indicated on the marking
label. If you are not sure of the type of
power supply to your home, consult your
product dealer or local power company.
For products intended to operate from
battery power, or other sources, refer to
the operating instructions.

POLARIZATION - The power supply may be

equipped with a polarized alternating-cur­rent line plug (a plug having one blade
wider than the other). This plug will fit into
the power outlet only one way. This is a
safety feature. If you are unable to insert

the plug fully into the outlet, try reversing
the plug. If the plug should still fail to fit,
contact your electrician to replace your
obsolete outlet. Do not defeat the safety
purpose of the polarized plug.

POWER-CORD PROTECTION - Power sup-

ply cords should be routed so that they are
not likely to be walked on or pinched by
items placed upon or against them, paying
particular attention to cords at plugs, con­venience receptacles, and the point where
they exit from the Decoder Amplifier.

LIGHTNING - For added protection for the

DTT2500 Digital system during a lightning
storm, or when it is left unattended and
unused for long periods of time, unplug it
from the wall outlet. This will prevent dam­age to the Decoder Amplifier due to light­ning and power-line surges.

OVERLOADING - Do not overload wall out-

lets, extension cords, or integral conve­nience receptacles as this can result in a
risk of fire or electric shock.

OBJECT AND LIQUID ENTRY - Never push

objects of any kind into the Decoder Am­plifier through openings as they may touch
dangerous voltage points or short out parts
that could result in a fire or electric shock.
Never spill liquid of any kind on the speak­ers or the Decoder Amplifier.

SERVICING - Do not attempt to service the

any part of the DTT2500 Digital yourself
as opening or removing covers may ex­pose you to dangerous voltage or other
hazards. Refer all servicing to qualified
service personnel.

DAMAGE REQUIRING SERVICE - Unplug

the power supply from the wall outlet or
other power source and refer servicing to
qualified service personnel under the fol­lowing conditions:
a) When the power supply cord or plug is
damaged.
b) If liquid has been spilled, or objects
have fallen into the subwoofer.
c) If the Decoder Amplifier has been ex­posed to rain or water.
d) If the subwoofer does not operate nor­mally by following the operating instruc­tions; or exhibits a distinct change in per­formance.
e) If the product has been dropped or
damaged in any way.

REPLACEMENT PARTS - When replace-

ment parts are required, be sure the ser­vice technician has used replacement
parts specified by Cambridge SoundWorks
or have the same characteristics as the
original parts. Unauthorized substitutions
may result in fire, electric shock, or other
hazards.

SAFETY CHECK - Upon completion of any

service or repairs to the DTT2500 Digital
system, ask the service technician to per­form safety checks to determine that the
DeskTop Theater 5.1 system is in proper
operating condition.

WALL OR CEILING MOUNTING - The

DTT2500 Digital satellites should be
mounted to a wall or ceiling only as rec­ommended by Cambridge SoundWorks.

Playback Levels

DDT2500 Digital is intended for
individual or small group listening and
will achieve surprisingly high output
levels. However, playing the system
continuously at overly loud, distorted
levels on heavy bass program material
may cause its internal fuse to blow.

The fuse can be replaced only by a
qualified representative. To avoid this
inconvenience and a possible non­warranty repair charge, reduce the
playback volume when the system
shows obvious signs of stress, i.e. it
sounds “raspy,” “fuzzy,” and/or
“muddy.”

Speaker PlacementInstallation Sequence

1. Read all of the instructions before
installing the speaker system.

2. Using the placement instructions as
a guide, position the satellites, the
center channel speaker and
subwoofer around your computer.
Install the Desktop Stands and
Floor Stands as appropriate. If you
wish to substitute a powered
subwoofer for the subwoofer that
comes with the DTT2500 Digital,
read Substituting a powered
subwoofer page 5.

3. Connect the satellite speakers,
center channel speaker, and
subwoofer to the back of the
Decoder Amplifier.

4. Connect the Dolby Digital output
of your digital program source
(typically a DVD player) to the
Dolby Digital input of the Decoder
Amplifier.

5. Connect your normal audio signal
sources via the Line In and Rear In
inputs. An owner of a Sound
Blaster Live! sound card with a
Digital DIN output should use the
supplied cable to connect it to the
Digital DIN input instead.

6. With the Decoder Amplifier’s
power switch “off”, connect the
power supply adaptor to the
Decoder Amplifier.

7. Turn on the power. Use the
SPEAKER TEST mode to position
and balance the speakers.

8. You may wish to experiment with
speaker placement briefly before
concealing the connecting cables
and making the installation more
permanent.

9. The unit is ready for you to enjoy.
Refer to the Quick Reference guide
for information about settings for
specific program sources like DVD,
CDs, Video CD and games.

The Front Satellites. The left front
and right front satellites play stereo
music, the off-screen sounds of
video playback and the front
channels of four channel games.

These satellites should be placed

to the sides of your monitor (see
Diagram A). Be sure to have a clear
line of sight from your listening
position to these satellites. The
satellites intended for front
placement have 3 meters (9 feet) of
cable.

Install the satellite’s Desktop
Stands when using them on the
desktop (see page 6).

The satellites may also be hung on the
wall behind the monitor using the screw
and wall anchors provided (see
“Mounting The Speakers”, page 7).

If you wish to save desktop space,
use the hook and loop fasteners to
attach the satellite speakers to the sides
of the computer monitor (see Diagram B).

The Center Channel Speaker. The
center channel speaker provides the on­screen effects and dialog in Dolby
Digital, Dolby Surround or Creative
Multi Speaker Surround modes. It
should be placed as close to the center
of your computer monitor as possible.

Playing VCD Movies:

Using PC-DVD player on PC

1. Disable the ‘Creative Multi
Speaker Surround’ (CMSS)
function by pressing the CMSS
button until all four LEDs are
off.

For VCD movies with Dolby

Surround-encoded stereo
program:

You can use the Dolby Pro
Logic decoder, by selecting PRO
LOGIC DIGITAL IN, to experi­ ence 5.1-channel movie
viewing.

For VCD movies:
You will have Digital 2.1
channel output. To enhance
the experience, enable the
Digital Pro Logic by pressing
the DOLBY SURROUND button
until the DIGITAL IN LED lights
up.

Using VCD player on TV

1. Connect Video Out of the VCD
player to Video Input of your
television.

2. Connect the Audio Out of the
VCD player to the Line In of
your DTT2500 Digital decoder
amplifier unit.

3. Select the MOVIE mode by
pressing the Creative Multi
Speaker Surround (CMSS)
button until the LED for MOVIE
mode lights up.

You can experience surround sound
instead of mono/stereo sound; all
dialog and central sounds will be
heard through the center speaker,
while music and off-stage sounds are
heard through the other four satellites.

Using SoftMPEG player or
PlayCenter on PC

1. Select the MOVIE mode by
pressing the Creative Multi
Speaker Surround (CMSS)
button until the LED for MOVIE
mode lights up.

This mode lets you experience
the surround sound with 5.1­ channel output; all dialog and
central sounds will be heard
through the center speaker,
while music and off-stage
sounds are heard through the
other four satellites.

If you are using PlayCenter to play
the VCDs, disable all CMSS effects
in your PlayCenter - use only
DTT2500 Digital CMSS MOVIE
mode.

There are many mounting
possibilities. The monitor stand can
be attached with hook and loop
fasteners to the top of the computer
monitor. It directs the sound down
towards the listener (see Diagram C).

If your computer monitor’s
construction directs the sound of the
center channel satellite towards you
without a stand, attach the satellite
directly to the top of the monitor,
using the hook and loop fasteners (see

Diagram D). Position the face of the
center channel so that it is as far
forward as possible.

Use a Desktop Stand to position a
center channel satellite in front of the
monitor. It directs the sound up
towards the listener (see Diagram E).

The Center Speaker may also be
hung on the wall behind the monitor
using the screw and wall anchors
provided (see “Mounting The
Speakers”, page 7).

The Rear Satellites. The rear
satellites provide the surround
effects in Dolby Digital, Dolby
Surround and Creative Multi
Speaker Surround modes. They also
provide the discreet rear sounds
produced in four channel gaming.

5 meters (16 feet) of cable is
provided with the two remaining small
satellites for more flexibility in rear
channel placement.

The rear satellites may be placed in
any convenient sites alongside the
listener, including sites slightly
forward of the listening location.

The rear satellites do not have to be
at exactly the same height, nor at the

C

D

E

F

G

same height as the front satellites.

If you have side walls close to your
listening position, excellent place­ment for the rear satellites is slightly
behind your listening position, slightly
above ear level (see Diagram F). The
satellites may be hung on the wall
using the screw and wall anchors
provided (see Mounting The
Speakers page 7).

Do not be concerned if this
placement is not practical. Any rear
satellite placement to the left and right
side of the listening position will
provide strong directional and
surround effects.

5

14

The rear satellites may be installed on
their convenient floor stands. While
listening, the stands should be positioned
to the left and right of your listening
position (see Diagram G).

The Floor Stands are small enough
to be stowed underneath a desk when
not in use. See page 7 for floor stand
assembly instructions.

Larger work surfaces can accommo­date both front and surround pairs of
satellites on their Desktop Stands. Try
the extreme corners of a desk using the
Desktop Stands (see Diagram H).

Also, you may attach the rear
satellites under a desktop or at the
sides of a desk using the hook and
loop fasteners (see Diagram I).

After you have positioned the rear
satellites, use the test sound to make
sure each speaker can be heard
clearly.

The Subwoofer. The subwoofer’s
optimum position is on the floor
against the wall under the computer
desk. The nearer the subwoofer is to
the corner of the room, the stronger
its maximum bass output will be. We
strongly recommend placing the

subwoofer on the floor (see Diagram J).

Leave at least 8 cm (3 inches) of
space between the subwoofer face
and a wall. Small objects in front of,
but not touching the subwoofer (table
legs, for instance) will have no effect
on its sound. If you have no
available floor space, the subwoofer
can be placed on a shelf, desktop or
other sites, but its maximum output
will be reduced. The subwoofer is not
magnetically shielded, so position it
at least 18 inches away from a
computer monitor.

Speaker Wire and Stand Installation

Typically , the 3 meter speaker
cables will connect the front and
center satellites to the Decoder
Amplifier and the 5 meter cables
will connect the rear satellites to
the Decoder Amplifier. A panel of
twelve self-adhesive labels is
provided to identify each satellite
and subwoofer and the opposite
end of the cable connected to a
satellite and subwoofer.

1. Identify a 3 meter cable. Most
often, a satellite will be used with a
desktop stand. In this case, thread
the bare wire end of a 3 meter cable
through the hole in the desktop
stand. Connect this end to a
satellite (as shown in Diagram K).
Carefully insert the desktop stand’s
attachment arm into the socket in
the back of the satellite, taking up
any slack in the cable as required.

2. To use this satellite in the front left
position, remove the backing from
the small, round “L” label and
apply it to the back of the satellite
(see Diagram K).

3. Remove the backing from the
remaining, longer “L” label and wrap
it around the opposite end of the
speaker cable near the RCA-type plug.

4. Place the satellite in the front left
position.

5. Repeat this process using another 3
meter cable for the front right satellite,
using the “R” labels.

6. Connect another 3 meter cable to a
satellite. Use the “C” (center) labels.
If used, the Monitor Stand attaches to
the satellite in the same manner as the
Desktop Stands, although it does not
have a hole for the speaker wire.
Route the wire to the left or right side
of the attachment strut. Position the
satellite.

7. If you wish to use the Floor Stands
with the rear satellites, assemble the
stand according to Attaching The
Floor Stand instructions on page 7.
Use the RS and LS labels (right and
left surround) and 5 meter cables.

8. Connect the subwoofer using the last 3
meter cable to the “SUB” labels.

Diagram K: To connect the wire
speakers to the spring-loaded tab to
expose the connection hole. Insert
the bare end of the wire into the
exposed hole, then release the tab to
lock the wire in place. Connect wires
with red bands to red tab connectors,
and unmarked wires to black tab
connectors.
Notes: Matching red wires to red
tabs and unmarked wires to black
tabs insures the speakers all play “in
phase”. “Out-of-phase” connections
will do no electrical harm, but the
overall sound quality will be greatly
reduced. You can substitute regular
18 gauge speaker wire to create
longer cables, if needed.

Creative Multi Speaker
Surround (CMSS)

CMSS is a 2-channel to 5.1-channel
sound processor similar in some aspects
to a Dolby Surround with Pro Logic
processor.

CMSS Music mode creates a
convincing 5.1 channel surround
soundfield with typical stereo sources,
whether they are Dolby Surround­encoded or not. It works well with Dolby
Pro Logic, WAVE, AVI and MIDI
program material. In essence, CMSS
Music mode puts you “on the stage”
for the music’s performance, surround­ing you with the performers.

In a similar manner, CMSS Movie
mode provides the sonic impression of
being front and center at a movie
screening. Dialog and all normally
centered sounds from a stereo program
are heard through the center speaker. Use
this mode whenever a music program has
sounds you want to blend with on-screen
action or dialog.

Unlike Pro Logic decoding, CMSS
Music, Movie and Four Point modes
are appropriate for use with multi­coded sources such as DVD games. In
some game titles, the movie sequences
may be encoded in Dolby Surround
but the game sequences may be in the
WAV format. CMSS Movie mode
supports 6-channel output for .WAV,
.AVI, .MIDI and other audio software
formats. Few, if any of these kinds of
formats are Dolby Surround encoded.

The FOURPOINT mode passes
the four discreet channel audio of
four-channel games direct to each
satellite channel. It does not synthe­size rear channel output, so stereo
signal in this mode will play just
through the front two speakers and
subwoofer.

The STEREO mode plays the Left
and Right Front speakers and the
subwoofer. It also lets you hear the
stereo downmix from any DVD.

Audio Mode Selection

The stereo soundtracks of some
movies on the Video CD (VCD
format) contain different languages.
For example, a two channel soundtrack
may contain Mandarin on the right
channel and English on the left
channel. The VCD program literature
should indicate the presence of dual­language soundtracks. Similarly, some
movies in the DVD format will contain
dual-language soundtracks. DTT2500
Digital lets you select one of these
languages and play it through both the
Left and Right speakers.

If there is no indication of which
channel is which and you hear two
different language soundtracks during
stereo playback, select the “LL” and
“RR” settings until you find the
language soundtrack you want.

The Audio Mode selection feature

can only be used with the PCM digital
soundtrack of a Video CD or DVD
with a stereo soundtrack, not a DVD
encoded with Dolby Digital 5.1 sound
or Dolby Surround-encoded material.
If you have an analog program with
separate left and right channels (the
analog output of a CD ROM, or the
analog stereo output of a “software”
video CD, for instance), you will have
to use the balance control in your PC’s
audio software to mute the undesired
channel.

Dolby Digital

Dolby Digital (earlier called AC-3)
delivers five discreet full-range
channels (left front, center, right front,
left surround and right surround) plus a
separate Low Frequency Effects (LFE)
channel.

Many soundtracks on the latest
generation laser discs, DVDs and High
Definition Television (HDTV), are
encoded with Dolby Digital technol­ogy.

When a 5.1 channel Dolby Digital
program source is playing, such as
from a Creative PC-DVD player, the
Dolby Digital indicator light will
illuminate automatically.

Note: Not every section of a DVD
will be 5.1-channel encoded. On many
DVDs, only the main movie program
will be available in 5.1 channel sound.
Other supporting chapters (like a
“Director’s Comment” section) may be
in stereo or mono. These sections will
not light the Dolby Digital indicator
even though the sound will be properly
reproduced by the DTT2500 Digital.

Dolby Pro Logic

Dolby Surround is an earlier
surround sound standard which is
decoded with a Pro Logic processor in
the DT2500 Digital. The Pro Logic
steering circuitry derives separate
center and rear channels from encoded
stereo program sources.

Pro Logic processing provides a
convincing movie soundfield when the
material is specifically encoded for
Dolby Surround. Most older stereo
movie soundtracks will only be
encoded for Dolby Surround, even
though the program source may be a
DVD’s digital output. Most DVDs
containing Dolby Surround program
material will cause both the Dolby
Digital and Digital Pro Logic lights to
illuminate. DTT2500 Digital will
decode these digitally transferred
Dolby Surround programs through the
digital Pro Logic decoder automatically.

When listening to DVD movies with

5.1 channel Dolby Digital sound, be
sure to listen only to the digital program
source. You can insure this by:

1)making sure your DVD
player’s stereo downmix is
not sent to your soundcard. For
example, disconnect any cable
link between the cards.

2)making sure all four CMSS
indicator lights are off

(MUSIC, MOVIE,FOURPOINT
and STEREO)

3)muting the “CD” input of
your computer’s software mixer/
volume control application.

When playing a DVD game with a
mix of Dolby Digital 5.1 sound (a
digital signal at the SPDIF input) and
soundcard wavetable output (a signal
at the analog input), be sure to engage
the FOURPOINT mode in the CMSS
settings.

CD-ROMs and CD’s with Dolby
Surround encoding will feature
the Dolby Surround logo at the
beginning of the program or on the
packaging. Process these programs by
making sure all CMSS indicator lights
are off and selecting the Pro Logic
Analog Input setting of the Surround
Mode button.

Do not select a Pro Logic decoding
mode if the program material is not
encoded for Dolby Surround.
Excessive center channel output will
result, and most stereo effect will be
lost. Use CMSS “Movie” or “Music”
modes to upmix stereo programs to a
realistic 5.1 channel sound field.
