Connecting the Acoustimass® module to your receiver
CAUTION: Do not connect the Acoustimass module directly to your television unless the
television provides surround decoding circuitry and amplified outputs for all channels.
Use the 20 foot (6 m) cable with five wire pairs to connect the Acoustimass module to your
surround sound receiver. Refer to Figure 8.
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 INPUTS FROM RECEIVER OR AMPLIFIER jacks. Black connectors go into L and R
jacks. Gray connectors go into C, LS, and RS jacks.
Checking your connections
Check all connections from the receiver to the Acoustimass module and the module to the
cube speakers. Check to be sure all speakers are connected to the proper terminals accord-
ing to their position in your room. Refer to Figure 8.
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.
CAUTION: Do not allow exposed wires to brush against each other; this could damage your
receiver.

Setting Up Your Acoustimass® 6 Speaker System
Attaching the module end cover
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 of the module after all connections
have been checked (Figure 10). Gently push the end cover into the grommets on the Acousti-
mass module.
Your set up is complete. Enjoy your Acoustimass 6 speaker system.

Using your receiver’s test tone to verify connections and adjust
the volume level
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.
Balancing 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.
Listening to spacious stereo sound
Try setting your receiver to the HALL, DANCE, or JAZZ surround mode while listening to
music from a CD or cassette tape. This enables you to enjoy a wide stereo image reproduced
by the front speakers, plus the ambience and spaciousness provided by your surround
speakers.
Listening to 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.
Note:  If your television has surround sound or any sound enhancement feature built in
(“wide” or “enhanced”), turn it off. Set the TV for stereo playback only.
Using your Dolby Pro-Logic receiver
For use in video applications, be sure the SURROUND SOUND center mode of your receiver
is set to NORMAL (Figure 11). You may depress the Loudness button (Bass Boost or Super
Bass on some receivers) to see if you prefer that video sound.

EnglishUsing 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 and turn the LFE (low-frequency effects) ON.

Cleaning your 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.
