Setting Up
At the Acoustimass® module, check to be sure the connectors are firmly inserted into the
proper OUTPUT TO CUBE SPEAKER jacks.
• The black L connector goes into the L jack.
• The gray C connector goes into the C jack.
• The black R connector goes into the R jack.
Connect the module to the surround cube speakers
Use the 50 foot (15 m) cable with gray connectors to join the Acoustimass module to the
surround speakers.
• The gray connector marked LS goes into the gray terminal on the left surround speaker
(to your left as you face the TV).
• The gray connector marked RS goes into the gray terminal on the right surround
speaker.
At the Acoustimass module, make sure the gray connectors are firmly inserted into the LS
and RS OUTPUT TO CUBE SPEAKER jacks.
Connect the module to the receiver
Use the 20 foot (6 m) cable with five wire pairs to connect the Acoustimass module to your
surround sound receiver.
1. Connect all wires to the receiver in phase (+ to + and – to –).
a. Connect each wire marked with a red collar (+) to the appropriate red (+) output.
b. Connect each plain wire (–) to the appropriate black (–) output.
2. Match the label on the red collar of each wire pair to the SPEAKER OUTPUT label on
the receiver:
a. LEFT wires go to the LEFT FRONT SPEAKER OUTPUT connections.
b. CENTER wires go to the CENTER SPEAKER OUTPUT connections.
c. RIGHT wires go to the RIGHT FRONT SPEAKER OUTPUT connections.
d. LEFT SURROUND wires go to the LEFT SURROUND (rear) SPEAKER OUTPUT
connections.
e. RIGHT SURROUND wires go to the RIGHT SURROUND (rear) SPEAKER OUTPUT
connections.
3. At the Acoustimass module, check to make sure all connectors are firmly inserted into
the proper INPUT FROM RECEIVER OR AMPLIFIER jacks. Black connectors go into L
and R jacks. Gray connectors go into C, LS, and RS jacks.
CAUTION:
Do not connect the Acousti-
mass module directly to your
television unless the television
provides surround decoding
circuitry and amplified outputs
for all channels.

Setting Up
Check the connections
Check all connections from the receiver to the Acoustimass® module and the module to the
cube speakers, making sure the two speakers with black terminals are connected as front
speakers (Figure 11). Check to be sure all speakers are connected to the proper terminals
according to their position in your room (Figure 12).
At the receiver, make sure the wires are connected in phase (+ to + and – to –). Incorrect
wiring can result in a total loss of Acoustimass module output.
Be sure to correct any wiring problems before you plug your receiver in and turn it on.

 Setting Up
Attach the module end cover, if needed
The module end cover is designed to hide the cabling and extend the smooth, clean lines of
the Acoustimass® module. However, because the cover has a beveled surface, you cannot
stand the module on that end with the cover in place.
If you plan to use the cover, attach it to the cable end after all connections have been
checked (Figure 13). Gently push the end cover into the grommets on the Acoustimass
module.
Your set up is complete. Enjoy your Acoustimass-6 speaker system.

Using Your  Acoustimass®-6 Speakers
For realistic home theater sound
Each speaker produces only the sound directed to it by the steering logic in your surround
sound receiver. During a surround sound program, the front and center speakers will emit
sound almost constantly, while the surround speakers may be silent for periods of time.
How to set your Pro-Logic receiver
For use in video applications, be sure the SURROUND SOUND center mode setting of your
receiver is on NORMAL (Figure 14). You may press in the button labeled Loudness (Bass
Boost or Super Bass on some receivers) to see if you prefer that video sound.
Use the test tone on your receiver to further verify connections and to adjust the volume
level of the speakers.
To use the test tone
1. Press test tone ON at the remote.
2. Listen and confirm that each speaker reproduces sound as the tone moves from speaker
to speaker in this order: LEFT, CENTER, RIGHT, SURROUND. One tone should come
from both SURROUND speakers at the same time.
3. Adjust the volume levels of the CENTER and SURROUND speakers to achieve the
balance you prefer for your listening area.
Instructions for this process vary, depending on the brand and model of receiver you are
using. Follow your receiver owner’s guide instructions for more details on using the test tone.
To balance the bass and treble
Upholstered furniture, wall-to-wall carpets, or heavy drapes can muffle treble (high notes),
making your speaker system sound bass heavy. Bare floors and walls and hard surface
furniture can make your speaker system sound too shrill. After listening to your speakers,
you may want to adjust the balance of bass and treble. You can use the bass and treble
controls on your receiver.
Suggestion for spacious stereo sound
Try setting your receiver to the PHANTOM surround mode while listening to music from a CD
or cassette tape. This will enable you to enjoy a wide stereo image reproduced by the front
speakers, plus the ambience and spaciousness provided by your surround speakers.
If your receiver has a Loudness button, turn that off during regular stereo playback.
How to set your Dolby Digital (AC-3) receiver
Your Acoustimass-6 speakers are compatible with the output from Dolby Digital (AC-3)
receivers. Take special care to set the channel output according to the specifications listed in
the chart below. The Acoustimass speaker system is a full-range system and must be set as
LARGE speakers on the Dolby Digital screen menu. An exception is the center speaker,
which must be set as SMALL. Turn the subwoofer OFF. Finally, turn the LFE (low-frequency
effects) ON and set the crossover frequency to 200 Hz.
Receiver channel output                           Proper setting
Left and Right Front ............................................ LARGE
Center ................................................................. SMALL
Left and Right Surround ..................................... LARGE
Subwoofer ............................................................. OFF
LFE (low-frequency effects) .................................... ON
Crossover frequency ........................................... 200 Hz
Follow the receiver owner’s guide instructions for using the receiver test tone to verify your
connections and to adjust the volume levels of the speakers.

Maintaining Your  Acoustimass®-6 Speakers
Problem What to do
Troubleshooting
If you have a problem with your Acoustimass-6 speakers, turn off your sound source and try
the solutions below. If you still have a problem, contact your Bose® dealer to arrange for
service. Or, to contact Bose directly, refer to the inside back cover of this guide.
• Make sure the power cord of the receiver is plugged into an
operating AC wall outlet and the receiver is turned on.
• Be sure to select a source at the receiver (video, CD, tuner). System does not
function at all
•  Check the cube speaker and Acoustimass module connections.
Turn ON receiver.
•  Check connections of external components to the receiver.
•  Increase the volume.
•  Disconnect any headphones. No sound
•  Move the Acoustimass module closer to a wall or corner to
increase bass. Move it farther from a wall or corner to decrease
bass. Or adjust the bass/treble control on the receiver slightly. Not enough or too
much bass
Cleaning the speakers
Wipe the cube speakers using a damp cloth. Do not use solvents or chemicals. Do not
allow liquids to spill on or objects to drop into the Acoustimass module or the speaker
grilles. You may vacuum the grilles carefully; the drivers are directly behind the grille cloth.
No other maintenance is needed.
No bass Sound is distorted •  Make sure speaker cable is not damaged.
•  Reduce the volume of any external components connected to
the receiver.
•  Make sure the speaker connections at the receiver or amplifier
are correct (+ to + and – to –).
• If you are using the Dolby Pro-Logic mode, make sure surround
sound is turned ON.
• If you are using Dolby Digital (AC-3) programming, verify that
the settings are correct at the receiver. Also, be sure the source
material (laser disc or broadcast programming) is Dolby Digital
or AC-3 encoded. •  If your surround sound receiver is Pro-Logic, be sure your
receiver is connected to a stereo sound source (TV, VCR,
laserdisc or DSS player) by an RCA stereo cable. If the receiver
is connected directly to a stereo television, make sure that all
other program sources (VCR, laserdisc or DSS player) are
connected to the TV using RCA stereo cable as well.
• If your surround sound receiver is Dolby Digital (AC-3), be sure
the sound source (DSS, laser disc or DVD player) is connected
directly to your receiver as described in your receiver owner’s
guide. No surround sound
