READ INSTRUCTIONS - All safety and oper-

ating instructions should be read before the

DeskTop Theater 5.1

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

DeskTop

Theater 5.1

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 Sound­Works, 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

DeskTop Theater 5.1

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

DeskTop Theater 5.1

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

DeskTop Theater

5.1

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

DeskTop Theater 5.1

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

experience the full potential of Dolby
Digital

®

multichannel sound from
your computer. It makes the most of
your computer DVD player,
processing both Dolby Digital and
Dolby Surround

®

program material.
It will decode the Dolby Surround
cut-scenes in many of today’s best
CD-based action games, and it’s
ready for the new era of DVD­based games.

DeskTop Theater 5.1 offers discrete

four-channel support for Microsoft

derivatives.

Also included is Creative Multi
Speaker Surround, which lets you
hear all of your favorite stereo
program material with a new and
exciting three-dimensional quality.

Inspecting
For Damage

Important Notes

channel sound cards such as Sound
Blaster 16 or the Sound Blaster
AWE series can also be used with
DeskTop Theater 5.1, 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 4
meters (12 feet) long. Typically, 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

These instructions assume you
have a DVD player with a SPDIF
output jack. This jack should provide
the Dolby Digital (AC-3) compressed
data stream (for example, the
Creative Labs PC-DVD Encore). These
instructions also assume your sound
card supports processing of
DirectSound

®

3D, including front and
rear two-channel minijack line
outputs (like Creative Labs Sound
Blaster PCI 64, PCI 128 or Sound
Blaster Live!). Conventional 2-

channel satellites, use the pair with
the longer cables instead.

One satellite of each pair has a
white plug. The other satellite has a
red plug. Use a satellite with a white
plug in the Left Front and Left
Surround positions. Use a satellite
with a red plug in the Right Front
and Right Surround positions.

The Subwoofer and Center
Channel speakers both have black
plugs on their cables to help
distinguish them from the smaller
satellites.

All the speakers are magnetically
shielded, including the subwoofer.
