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, 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 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 speak­er 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 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 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 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 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 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.

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 intersection of two room surfaces, the maximum bass output 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.
Because all satellite speakers will have different sensi­tivity, final adjustment should be done by ear even if the settings do not agree with those shown here.
SATELLITES
Refer to the instructions that came with your satellite speakers.

CONNECTIONS
Volume Control
It is not necessary to connect the Volume Control if your audio signal source provides an output level adjustment. The volume control allows use with a source that do not have volume control, or where the source’s volume con­trol is inconvenient.
A) If you are using the ST50 Desktop Stand with
Newton Series MC50 or MC100 speakers, slide the Volume Control onto the support strut on one of the stands.
If you are not using the ST50 Desktop Stands, we have included a piece of hook and loop fastner material so that you may attach the control to any convenient surface.
B) Insert the Volume Control’s plug into the jack
marked VOLUME CONTROL on the Subwoofer input panel until it snaps in place.
Signal Connections
C) 5.1 Input Group (F,R, and C/S minijacks):
Connect the Front, Rear, and Center/Subwoofer signals to these jacks. The color code of the sup­plied cables should match the jacks.
D) Auxilliary Input (one minijack): Connect a
second stereo source to this jack. Using a cable appropriate for your source unit. Signal at the Auxilliary input will be mixed with the front and subwoofer channels. Note: There will be no center or rear channel output when using this input.

Speaker Connections
The BassCube 851 is supplied with speaker cable ter­minated with an RCA plug on one end and tinned bare wires on the other end. Each cable is color-coded to match jacks on the rear panel of the subwoofer.
White – Left Front speaker Red – Right Front speaker Green – Center Channel speaker Blue – Left Surround speaker Gray – Right Surround speaker
5-meter cables are supplied for the front and center channels, and 15-meter cables are supplied for the rear channels. These cables may be shortened if desired. If you need to extend these cables, connect another length of two-conductor speaker cable to the two bare wires with wire nuts.
Begin by routing each speaker cable from the sub­woofer to the location of each speaker. Connect each cable to its corresponding speaker according to the instructions supplied with that speaker. Speaker con­nectors could be spring terminals, binding posts, or screws depending on the make and model. Be sure to maintain the proper polarity at each connection by using the gray insulated conductor of the supplied cable for “+” and the black insulated conductor for “–.” Finally, insert each cable’s RCA plug into the matching RCA jack on the rear panel of the subwoofer.

AC Connection and Placement
Make sure the subwoofer Power switch is in the OFF position (O).
Plug the supplied power cable first into the subwoofer back panel AC socket. Then connect it to an AC power socket.
Place the satellites and subwoofer in their preferred positions, then switch the Power swith to the ON (I) position.
BassCube 851 Manual 6/11/02 3:39 PM Page 10
OPERATION AND FINAL ADJUSTMENT
1) Use the Volume Control or the signal source control to vary output level.
2) The BassCube 851 has built-in bass management. If you are using a Dolby Digital
®
or DTS®source, set
the surround processor settings to:
SUBWOOFER – “Off” or “None” LEFT AND RIGHT MAIN SPEAKERS – “Large”
If the processor gives you the choice to select “Large” for the center channel and surround speak­ers, do that also.
3) Defeat or cancel any “tone control” or other sound adjustments within your audio program source. Portable CD players may have “bass boost” switch­es and many computer sound programs have audio adjustments concealed in drop-down menus.
3) If possible, play a variety of program material with good deep bass content to judge the best setting of the Bass control and Treble switch. In most cases, setting the Treble switch to “flat” will give the most accurate sound.
In situations where you are very close to the speak­ers, such as in a desktop/PC system, the “reduce” position may be preferred.
Auto Standby Mode
When audio signal is absent for 30 seconds or more, the BassCube 851 amplifier goes into Standby Mode. It is normal for the BassCube 851 to remain slightly warm when in Standby Mode. It may be left in Standby Mode indefinitely.
Cleaning
The painted surfaces of the satellites and subwoofers should be wiped with a cloth or brushed clean.
