Before you begin
Thank you for purchasing the Bose® Acoustimass® 3speaker system Its quality construction
and advanced technologies result from years
of ongoing research at Bose
Bose patented Acoustimass speaker technology delivers full, natural audio performance and,
for all
of the sound it produces, this Virtually Invisible® system takes up very little space The
tiny cube speakers fit almost anywhere, while the Acoustimass module is designed to be
hidden behind drapes, under furniture, or
in the corner of the room
Unpacking the system
Unpack the system carefully Avoid setting the module down on its connection panel, which
could scratch asurface (Save the carton and packing materials
in case you ever want to ship
the system) If any parts appear damaged, do not attempt
to use the system Repack all parts
in the original carton and notify your authorized Bose dealer immediately
Figure 1
What the carton contains
Acoustimass module
Two cube speakers
[][]
Four (4) adhesive-backed
CO rubber feet
Cd Cd
Four (4) speaker cables, 20 feet long
Selecting locations for the cube speakers
You can place the cube speakers anywhere from 3to 15 feet (0 9 - 4 6 m) apart For the most
natural sound
in average sized rooms, place them 6 to 12 feet (1 8 - 37m) apart Magnetic
shielding allows you
to place them close to avideo screen without causing interference
Bose mounting accessories, including wall/ceiling mounting brackets, floor stands, and table
stands, add to your choice
of where to place the cube speakers For more information or to
order accessories, contact your Bose dealer or call Bose Customer Service directly Refer to
the list
of phone numbers inside the back cover

Selecting a location for the Acoustimass" module
The Acoustimass module can be hidden almost anywhere in aroom Leave at least 2inches
(5 cm) of space between the opening (port) and the wall To prevent interference, keep the
module at least 2feet
(0 6 m) from any video screen
For abalanced sound
in most rooms, place the module along awall within 5feet (15m) of the
corner
To increase bass response, move the module closer to acorner without blocking the
opening
To decrease the bass, place the module farther from the corner
) Note: When you decide how you will position the module, attach the rubber feet to the
bottom surface
to protect the module and the floor
Figure 2
Choices on how to position the
module
Using the cables correctly
Use the supplied cables to connect the cube speakers to the module and the module to your
amplifier or receiver
A. CAUTION: Be sure all components are turned off and unplugged from the power outlet
before making the connections
To place these components more than 20 feet (6 2 - 9 2 m) apart, you will need to splice in a
length
of 18-gauge speaker cable To place them more than 30 feet (9 2 m) apart, you will
need heavier gauge wire
(See the wire recommendations on page 10 ) You can get additional
speaker cable at electrical and hardware stores or by calling Bose Customer Service (See
the list
of phone numbers inside the back cover)
Speaker cables consist
of two insulated wires The insulation around one wire is marked with
aband or stripe This marked wire is always positive
(+) The plain wire is always negative (-)
These correspond
to the red (+) and black (-) terminals on the back of the speaker, amplifier,
or receiver Be sure to connect each wire to the proper terminal (positive to positive, negative
to negative)

Connecting the cube speakers to the Acoustimass® module
Use the following steps to connect the cube speakers to the rear panel of the Acoustimass
module
1Select one pair of wires, and locate the terminal tab on the rear ofthe left cube speaker
2Press the terminal tab on the back of the speaker and insert the marked wire into the red
(+) terminal and the plain wire into the black (-) terminal (Figure 3)
3Release the terminal tab to secure both wires
4Repeat this process with the other pair of wires and the right cube speaker
ACAUTION: Do not connectyour amplifier or receiver directly to the cube speakers Cube
speakers must be connected directly to the Acoustimass module
or damage will result
5Locate the terminals marked OUTPUTS TO CUBE SPEAKERS on the rear panel of the
Acoustimass module (Figure
4)
6Connect the free end of the left cube speaker cable to the left (L) pair of terminals Make
sure that the marked wire
is connected to the positive (+) terminal and the plain wire is
connected to the negative (-) terminal
7Repeat step 6for the right cube speaker cable, connecting its wires to the right
(R) pair of
terminals
Figure 3
Connecting the speaker cable
to the cube speaker
Connecting the Acoustimass module to your receiver or amplifier
Use the following steps to connect your Acoustimass module to your receiver or amplifier
A CAUTION: Correct wiring is important Incorrect wiring will result in little or no bass output
and could potentially damage the system
1Locate the terminals marked INPUTS FROM AMP OR RECEIVER on the rear panel of the
Acoustimass module (Figure
4)
2Connect either end of one of the remaining speaker cables to the left (L) pair of input
terminals Make sure that the marked wire is connected
to the positive (+) terminal and the
plain wire
is connected to the negative (-) terminal
3Connect either end of the final speaker cable to the right
(R) pair of input terminals Make
sure that the marked wire
is connected to the positive (+) terminal and the plain wire is
connected to the negative (-) terminal
6

4Connect the free end of the left (L) INPUTS cable to the LEFT speaker terminals of your
amplifier
or receiver Connect the marked wire to the positive (+) terminal and the plain
wire to the negative (-) terminal
5Connect the free end
of the right (R) INPUTS cable to the RIGHT speaker terminals of your
amplifier or receiver Connect the marked wire
to the positive (+) terminal and the plain
wire
to the negative (-) terminal
CAUTION: Before you plug in your receiver or amplifier, make sure that no strands of wire
from any terminal are brushing againstany other terminal Such "bridged" wires create short
circuits which can damage your receiver oramplifier

Completed connections
Checking your connections
To avoid damaging your speakers, check all connections and correct any problems before
plugging
in and turning on the amplifier or receiver Make sure the cube speakers are con-
nected to the module and not directly to the amplifier
or receiver

Checking the system
Make sure your system is working properly by following these steps
1
Turn on your amplifier or receiver
2
Turn the balance control on your amplifier all the way to the left You should hear music
from the left cube speaker only, although you may detect afaint sound from the other
cube speaker
You should also hear the module
3
Turn the balance control all the way to the right Now you should hear music from the right
cube speaker only, although you may also hear afaint sound from the left cube speaker
You should also hear the module
4Now play music that includes some deep bass passages Listen with the balance control
in the center position Compare that sound to what you hear with the balance control in
the far left position Then compare the sound in the center balance position with sound
when the control is
in the right position The bass should be the same or louder with the
control
in the center Be sure to return the balance control to the center position when you
are finished
If your system does not respond
as described, check all the wires for proper positive to
positive and negative to negative connections If your system still doesn't respond properly,
see "Troubleshooting" on page 9
Understanding automatic system protection
When played at high volume, the Acoustimass® 3system's automatic protection circuit
activates
to prevent damage to the system from electrical stress or overload When this
happens, you may notice aslight decrease
in volume, which is normal It indicates that the
power input may have exceeded safe levels Setting the volume at or above this level for
sustained periods is not recommended
R

Cleaning your speakers
Clean the cabinets of your Acoustimass® 3system using adamp cloth If necessary, use a
mild detergent such as dish soap Do not use any solvents, chemicals,
or cleaning solutions
containing alcohol, ammonia, or abrasives Do not allow liquids to spill through the speaker
grilles
or enter the Acoustimass module
