POWER-CORD PROTECTION – The AC power cords
should be routed so that they are not likely to be
walked on. No object should bring weight to bear on
to the AC power cords.
LIGHTNING – For added protection for the speaker
during a lightning storm, or when it is left unattended
and unused for long periods of time, unplug them from
the wall outlet. This will prevent damage to the speaker
due to lightning and power-line surges.
OVERLOADING – Do not overload wall outlets, exten-
sion cords, or integral convenience receptacles as this
can result in a risk of fire or electric shock.
OBJECT AND LIQUID ENTRY – Never use probes of
any kind to reach into the speaker as they may touch
dangerous voltage points or short parts that could
result in a fire or electric shock. Never spill liquid of
any kind on the speaker.
SERVICING – Do not attempt to service the speaker
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 speak-
er from the wall outlet or other power source and refer
servicing to qualified service personnel under the fol-
lowing conditions:
a) When the power-cord or plug is damaged.
b) If liquid has been spilled, or objects have fallen into
the speaker.
c) If the speaker has been exposed to rain or water.
d) If the speaker does not operate normally by follow-
ing the operating instructions; or exhibits a distinct
change in performance.
e) If the speaker has been dropped or damaged in
any way.
REPLACEMENT PARTS – When replacement parts
are required, be sure the service technician uses
replacement parts specified by Cambridge
SoundWorks or have the same characteristics as the
original part. Substandard substitutions may result in
fire, electric shock, or other hazards.
SAFETY CHECK - Upon completion of any service or
repairs to the speaker, ask the service technician to
perform safety checks to determine that the speaker is
in proper operating condition.
READ INSTRUCTIONS – All safety and operating
instructions should be read before the speaker is
operated.
RETAIN INSTRUCTIONS – The safety and operating
instructions should be retained for future reference.
HEED WARNINGS – All warnings on the speaker and
in the operating instructions should be adhered to.
FOLLOW INSTRUCTIONS – All operating and use
instructions should be followed.
CLEANING – Unplug the speaker from the wall outlet
or other power source before cleaning. Use a damp
cloth for cleaning.
ATTACHMENTS – Do not use any adapters or attach-
ments not recommended by Cambridge SoundWorks
as they may cause hazards.
WATER AND MOISTURE – Do not use the speaker
near water-for example, near a bath tub, wash bowl,
kitchen sink, or laundry tub; in a wet basement; or near
a swimming pool or other similar areas.
ACCESSORIES – Do not place the speaker on an
unstable cart, stand, tripod, bracket, or table. The
speaker may fall, causing serious injury to a child or
adult and serious damage to the product.
VENTILATION – Slots, openings and metal fins in the
cabinet are provided for ventilation, to ensure reliable
operation of the speaker and to prevent it from over-
heating. These areas must not be blocked or covered
such as by placing the product on a bed, sofa, very
deep pile rug, or other similar surface. The speaker
should not be placed in a built-in installation such as a
bookcase or rack.
HEAT – The speaker should be situated away from heat
sources such as radiators, heat registers, stoves, and
other products (including amplifiers) that produce heat.
POWER SOURCES – The speaker should be operated
only from the type of power source indicated on the
label. If you are not sure of the type of power supply to
your home, consult your dealer or local power company.
POLARIZATION – The speaker is 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.

TABLE OF CONTENTS
INTRODUCTION
Thanks for choosing the MegaWorks 210D
loudspeaker.
It features the finest drivers, precision internal
crossover and amplifier circuitry and an elegant enclo-
sure design.
The satellite speakers feature “rare earth” magnetic
assemblies which are strong, yet small and light. This
increases the interior volume of the satellite enclosure
for better low frequency performance.
The Product Development Team at Cambridge
SoundWorks believes there is no better combination of
audiophile-level attention to detail and reasonable cost.
Inspecting For Damage
Examine the speaker system carefully for shipping
damage. If there is any, do not install or use the sys-
tem. Return the speaker to the store where you made
the purchase or call Cambridge SoundWorks at 1-800
FOR-HIFI (1-800-367-4434) for assistance.
After Unpacking
Store the shipping carton and packing material for
future transport needs.
QUICK SETUP
If you have connected amplified subwoofer/satellite
systems before, the Wiring Guide on pages 8-9 may
be all you need to get set up and operating.

POSITIONING YOUR SPEAKERS
SUBWOOFER/AMPLIFIER
Place the Subwoofer cabinet on the floor, preferably
near a wall. Do not place it on a desktop or shelf.
For maximum bass output, place the subwoofer near a
corner. If the subwoofer is placed away from the inter-
section of two room surfaces, the maximum bass out-
put will be reduced.
Use the Bass Level control to adjust the bass output to
your desired balance. Recommended Bass control
settings for each type of location are shown.
SATELLITES
Desktop Placement
The Desktop Stands improve the sound for both
a standing or seated listener.

POSITIONING THE SATELLITES
1111
Wall Placement
Avoid facing a satellite parallel to a nearby wall (within
6-8 inches). The reflected sound from the wall
degrades the sound coming directly from the satellite
(diagram A).
Try to position wall-mounted satellites so both are
approximately at your ear level while sitting or slightly
higher. Make sure the speakers form at least a 20-
degree angle with your listening position. An angle
greater than 55 degrees sounds like two separate
speakers, rather than forming a continuous image of
sound between the two speakers (diagram B).
When using the speaker for video sound, place the
satellites relatively close to the television monitor, form-
ing no more than a 45 degree angle with your listening
position (diagram C).
Shelf Placement
Place the satellites as close to the edge of the shelf as
possible for best sound (diagram D).

CONNECTIONS
Volume Control
A) If you are using the Desktop Stand, slide the
Volume Control onto the support strut on one
of the stands.
B) Insert the Volume Control’s plug into the jack
marked VOLUME CONTROL on the Subwoofer
input panel until it snaps in place.
It is not necessary to connect the Volume Control if your
audio signal source provides an output level adjustment
you would rather use.
Signal Connections
The MegaWorks 2.1 has two analog inputs and one
SPDIF digital input.
C) LINE IN A (analog): Connect the 3.5 mm minijack
output of any analog signal source to this 3.5 mm
stereo minijack input, using cable J.
LINE IN B is a second audio input that blends
with LINE IN A. Connect a second audio source
program here. For a source with a 3.5 mm minijack
output (like a headphone jack or line out jack on a
portable CD player), use a 2-meter signal cable
with a 3.5 mm miniplug at each end. Other sources
may need a cable with a 3.5 mm miniplug and two
RCA plugs or a 3.5 mm stereo miniplug and 3.5
mm stereo
minijack.
D) DIGITAL IN: Connect the output of a digital audio
signal source to this RCA jack. You can use cable I
to connect to most computer sound card digital
outputs. When a digital signal is present, the ana-
log audio inputs are automatically muted. Digital
signal format is auto-sensed.
Typical digital audio signals are 44.1 kHz 16 bit (like
CD audio) or 48 kHz 16 bit (like that stored on a
Digital Audio Tape-DAT).

Other Connection Situations
1) Using the MegaWorks 210D as a high performance
stereo television sound system.
a) A stereo television with audio signal output typically
has two RCA-type jacks (one red, one white). To
connect to these jacks, obtain a stereo signal cable
with two RCA plugs at one end and a 3.5 mm
stereo miniplug at the other end (a Cambridge
SoundWorks A12MMSRC 2-meter cable, for
instance). Connect the miniplug to LINE IN A of the
MegaWorks 210D and the RCA plugs to your televi-
sion’s red and white RCA jacks. (Do not connect to
yellow RCA jacks. These are video outputs.)
b) Some stereo televisions offer a choice of fixed or
variable audio output level. Choose the variable out-
put. The fixed output level bypasses the television’s
remote volume control.
c) Turn off your television’s internal speakers. This
control could be located on the front or back
control panels of your television, or it may be an
“on-screen” menu selection.

d) If your television has a variable audio output, you
may not need to connect the MegaWorks 210D’s
volume control. The television’s remote control will
adjust the volume level.
You will need to connect the MegaWorks 210D
volume control if either of these situations occurs:
* Noise is heard even at the television’s minimum
volume setting. In this case, connect the volume
control and set it low enough to make the noise
inaudible, then stow the volume control next to the
subwoofer.
* You find the MegaWorks is too “sensitive.” For
instance, if the output level is too loud when the
television “volume” setting is below 30%. Connect
the volume control and reduce it’s setting to
increase your television’s volume range. Then stow
the volume control next to the subwoofer.

2) Using the MegaWorks 210D as a sound system for a
component CD player.
Typically, there are two RCA-type jacks (one red,
one white) on the CD player. To connect to these
jacks, obtain a stereo signal cable with two RCA
plugs on one end and a 3.5 mm stereo miniplug at
the other end (a Cambridge SoundWorks
A12MMSRC 2-meter cable, for instance). Connect
the miniplug to LINE IN A of the MegaWorks 210D
and the RCA plugs to your CD player’s red and
white RCA jacks.
3) Using the MegaWorks 210D as a sound system for a
home stereo component with a digital output.
A home component digital output will typically be
an RCA-type jack. To connect to this output, obtain
a signal cable with an RCA plug at each end (a
Cambridge Works A1DCOAX2 2 meter cable, for
instance). If a cable with one RCA plug at each
end can’t be obtained, a stereo version can be
used. Just use one plug at each end of the
same color.
The MegaWorks 210D does not support optical
digital signals. The digital RCA jack output of many
components is labeled “coax” or “coaxial.”

Speaker Connections
To connect the 2-meter speaker cables (two wires at
each end):
Push back the red speaker input tab on a satellite,
exposing the wire hole.
Fully insert one of the wires with a red band into the
wire hole and release the tab.
Repeat the procedure with the adjacent speaker wire
and the black speaker input tab on that speaker.
Connect the two wires at the other end of that same
speaker cable to the red and black “R” speaker input
tabs on the subwoofer. This satellite becomes the
Right channel satellite.
Repeat the preceding process to connect the other
satellite (making it the Left channel satellite).

OPERATION AND FINAL ADJUSTMENT
161616
1) Use the Volume Control or the signal source control
to vary output level.
2) Defeat or cancel any “tone control” or other sound
adjustments within your audio program source.
Portable CD players may have “bass boost” switch-
es and many computer sound programs have
audio adjustments concealed in drop-down menus.
3) If possible, play a variety of musical CDs with good
deep bass content to judge the best setting of the
Bass and Treble controls.
Cleaning
The painted surfaces of the satellites and subwoofers
should be wiped with a damp cloth or brushed clean.
The grille panel material can be vacuumed or brushed
clean.
