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 subwoofer
or control module 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 subwoofer or control module due to
lightning and power-line surges.

OVERLOADING – 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 use probes of
any kind to reach into the subwoofer or control module
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 subwoofer, control mod­ule or control module power supply.

SERVICING – Do not attempt to service the subwoofer
or control module 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 or control module from the wall outlet or other
power source and refer servicing to qualified service
personnel under the following conditions:

a) When the power-cord or plug is damaged.
b) If liquid has been spilled, or objects have fallen into

the subwoofer or control module.

c) If the subwoofer or control module has been

exposed to rain or water.

d) If the subwoofer or control module does not operate

normally by following the operating instructions; or
exhibits a distinct change in performance.

e) If the subwoofer or control module 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 subwoofer or control module, ask the
service technician to perform safety checks to deter­mine that the subwoofer or control module is in proper
operating condition.

READ INSTRUCTIONS – All safety and operating
instructions should be read before the subwoofer 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 subwoofer or control module
from the wall outlet or other power source before clean­ing. Use a damp cloth for cleaning.

ATTACHMENTS – Do not use any adapters or attach­ments not recommended by Cambridge SoundWorks
as they may cause hazards.

WATER AND MOISTURE – Do not use the subwoofer
or control module 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 subwoofer on an
unstable cart, stand, tripod, bracket, or table. The sub­woofer 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 subwoofer and to prevent it from over­heating. 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 subwoofer
should not be placed in a built-in installation such as a
bookcase or rack.

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 or control module
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 subwoofer 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.

INSPECTING FOR DAMAGE

Examine each part carefully for shipping damage. If

there is any, do not install or use the system. Return

the subwoofer to the store or merchant where you

made the purchase or call Cambridge SoundWorks at

1-800 FOR-HIFI (1-800-367-4434) for assistance.

1. low-pass:

Even though a subwoofer only produces “bass

notes”, the upper end of its range should be tailored

to blend well with your main speakers. The sub-

woofer should not produce any bass your main

speakers can produce. The low-pass control sets

this limit. The lowest setting (50 Hz) should be used

with large main speakers. Its middle settings should

be used with small floorstanding speakers or large

bookshelf speakers. Its highest setting should be

used with small speakers (see table on page 14).

2. On/Standby/Limit Indicator:

This indicator glows amber when the subwoofer is

in Standby. The subwoofer uses very little power in

this mode. It turns on rapidly whenever the main
system is used. This indicator glows green while the

subwoofer is On and operating. This indicator blinks
red whenever the subwoofer reaches its full output

(1000 watts for the P1000, 500 watts for the P500).

3. phase:

The phase control compensates for placement dif-

ferences between the main speakers, the subwoofer

and your listening position. Adjusting this control

affects the relatively narrow range of notes where

the main speakers and the subwoofer “overlap”.

Adjust it for maximum output in this narrow range (not

for “best sound”). The affect this control has can be

subtle. It’s easiest to adjust when percussion is playing

a repetitive pattern.

4. volume:

This control sets the overall output level of the sub-

woofer. Adjust it with the remote control for the best

overall blend with your main speakers, after you have

set the other controls.

5. equalizer level and equalizer frequency:

Your listening room’s shape and construction (and

where you listen within it) have an unpredictable affect

on deep bass. These two controls adjust deep bass.
equalizer frequency adjusts how deep into the bass

the subwoofer will respond. The 20 Hz setting indi-

cates the subwoofer is flat down to that frequency.
equalizer level adjusts the output centered around the

equalizer frequency setting.

These controls let you discover the strong and deep

sonic events in your favorite program material, part of

the fun of having a great powered subwoofer.

The lower you set the equalizer frequency and the higher

you set the equalizer level, the more amplifier power you

devote to producing the deepest bass.

This, in turn, can limit the maximum overall output of

your subwoofer. If you want maximum output, setting

the equalizer frequency at or above 30 Hz

can give it to you.
