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

Important
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. T o 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.”

Important Notes
These instructions assume you have
a DVD player with a coaxial Dolby
Digital (AC-3) output (for example, the
Creative Labs PC-DVD Encore).
These instructions also assume your
sound card supports processing of
DirectSound
rear two-channel minijack line outputs
(like Creative Labs Sound Blaster PCI
series or Sound Blaster Live! series).
Sound Blaster Live! owners should
utilize the exclusive Digital DIN
®
3D, including front and
connection, to hear the clearest digital
audio available. Conventional 2channel sound cards such as Sound
Blaster 16 or the Sound Blaster AWE
series can also be used with DTT2500Digital, but these cards will not
provide rear channel output when
playing games using DirectSound
®
3D
or its derivatives.
One pair of satellites has cables that
are 3 meters (9 feet) long. The other
pair has cables that are 5 meters (16
feet) long. T ypically, the two satellites
with the longer cables will be used on
the surround channels, but the
satellites are otherwise identical. If
you need extra cable length for the
front channel satellites, use the pair
with the longer cables instead.
All the speakers are magnetically
shielded, but the subwoofer is not.

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.
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)

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.
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
C
D
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).
E
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
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 TheSpeakers 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.
F
G
415
Page 9
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.
Substituting a powered
subwoofer. You may substitute a
powered subwoofer for the subwoofer
that comes with the DTT2500 Digital.
Connect its line level input (typically
an RCA jack) to the dedicated
subwoofer output on the back of the
Decoder Amplifier, using a shielded
audio cable with RCA plugs on each
end. Refer to the powered
subwoofer’s User Manual for
adjustment procedures.

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 V ideo 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. DTT2500Digital 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 V ideo 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.
Speaker Wire and Stand Installation
T ypically, 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. T o 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 TheFloor 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.

2. Insert one end of a supportextend to the support. There are
nine support extends for each
floor stand to enable you to adjust
to a suitable height.
3. Insert a rubber foot into each of
the bottom-most supportextends.
4. Insert the rear cable through the
back of the holder/cap.
5. Connect the frame to stabilise the
floor stand.
6. Connect the cable to the satellite
speaker and attach the satellite to
the holder/cap.
7. Tuck the cable neatly into the
grooves available on any of the
support extends.

Mounting The Speakers
Screw Mounting: The Satellite and
Center Channel speakers may be
hung on a wall using an M5 screw
and their keyhole openings.
First attach four self-adhesive feet
to the back of each satellite (see
Diagram P) insuring a vibration-free,
secure installation. Leave about
an inch of the screw-head exposed to
fit into the back of the speaker.
Plastic anchors may be needed to
3
/8 of
secure the screws into particularly
hard or soft material. If so, drill the
appropriate sized holes in the wall
and tap the anchors into the holes
until they are flush with the wall.
Insert the screws into the anchors
until they protrude
wall.

Surround Reference
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 T elevision (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.
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.
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.
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.
