measures:
❒
Reorient or relocate the receiving antenna.
❒
Increase the distance between the equipment and receiver.
❒
Connect the equipment to an outlet on a circuit different from
that to which the receiver is connected.
❒
Consult the dealer or an experienced radio/ TV technician.
CAUTION: To comply with the limits for the Class B digital device,
pursuant to Part 15 of the FCC Rules, this device must be installed
with computer equipment certified to comply with the Class B limits.
All cables used to connect the computer and peripherals must be

IMPORTANT SAFETY INSTRUCTIONS
READ INSTRUCTIONS - All safety and
operating instructions should be read before
the MegaWorks THX 6.1 650D 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 instruction s
should be adhered to.
FOLLOW INSTRUCTIONS - All operating
and usage instructions should be followed.
CLEANING - Unplug the subwoofer from the wall
outlet or other power source before cleaning. Do
not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.
ATTA C H ME N T S - Do not use attachments not
recommended by Cambridge SoundWorks and
Creative Technology as they may cause hazards.
WATER AND MOISTURE - Do not use the
subwoofer 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 MegaWorks
THX 6.1 650D system on an unstable cart,
stand, tripod, bracket, or table. The subwoofer
or satellites 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 and Creative Technology, 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 and Creative
Technology.
VENTILATION - Slots and openings in the
cabinet are provided for ventilation, to ensure
reliable operation of the subwoofer and to
prevent it from overheating; and 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 subwoofer should not be
placed in a built-in installation such as a
bookcase or rack unless proper ventilation is
provided or Cambridge SoundWorks’ and
Creative Technology ’s instructions have been
adhered to.
HEAT - The subwoofer should be situated away
from heat sources such as radiators, heat
registers, stoves, and other products
(including amplifiers) that produce heat.
POWER SOURCES - The subwoofer 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.
POLARISATION - The subwoofer may be
equipped with a polarised 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 polarised plug.
POWER-CORD PROTECTION - Power-
supply 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 subwoofer.
LIGHTNING - For added protection for the
MegaWorks THX 6.1 650D 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 subwoofer due to lightning and powerline surges.
OVER LOAD ING - Do not overload wall outlets,
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 subwoofer 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 subwoofer.
SERVICING - Do not attempt to service the
subwoofer 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 subwoofer 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 object have fallen
into the subwoofer.
c) If the subwoofer 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 replacemen t
parts are required, be sure the service
technician has used replacement parts specified
by Cambridge SoundWorks and Creative
Technology, or have the same characteristics as
the original part. Unauthorised substitutions
may result in fire, electric shock, or other
hazards.
SAFETY CHECK - Upon completion of any
service or repairs to the MegaWorks THX 6.1
650D system, ask the service technician to
perform safety checks to determine that the
MegaWorks THX 6.1 650D system is in proper
operating condition.
WALL OR CEILING MOUNTING - The
MegaWorks THX 6.1 650D satellites should be
mounted to a wall or ceiling only as
recommended by Cambridge SoundWorks and
Creative Technology.

Using Multiple Inputs
The MegaWorks THX 6.1 650D
allows you to mix a second audio
program source with the main
program source (Analog Input 1
or Digital Input).
About the built-in
Digital-to-Analog
Converters
MegaWorks THX 6.1 650D
features high performance true 24bit Digital-to-Analog Converters
supporting 44.1 kHz to 96 kHz
sampling rates. Using the 3.5 mm
4-pole mini-socket digital input
connection, owners of Sound
Blaster Live! and Audigy series
audio cards can enjoy the sonic
realism of movies featuring up to
5.1 channels of digital
soundtracks. (6.1 channel support
via analog inputs only.)

Controlling
Noise and
Distortion
MegaWorks THX 6.1 650D has
moderately high input sensitivity, so
it may amplify the hum and hiss
inherent in some audio program
sources. Any noise is not due to a
fault in the speaker system.
You can minimise background noise
as follows:
❒
Use the MegaWorks THX 6.1
650D remote control as your
master volume control.
❒
If your speaker system is
connected to a computer, adjust
the settings of your computer’s
sound control software. (If you
are using Creative Sound Blaster
software, this would be the
Surround Mixer application).
Turn off any input controls that
you do not need, such as
Microphone, and set the
remaining input controls to about
70% of their maximum volume.
❒
Adjust the master output volume
of your sound control software,
such that your speaker system
reaches a comfortably loud
volume in its default volume
settings.
