Placing the Acoustimass® module
Consider the guidelines below when choosing a location for the Acoustimass® module.
Make sure to place it:
• within reach of the cables to the music center and an AC (mains) power outlet
• at the same end of the room as the TV and the speakers (Figure 6)
• a minimum of 3 feet (1 meter) from the TV, to prevent interference from the module, which is 
not magnetically shielded
Figure 6
3-foot distance between 
the Acoustimass module 
and the TV
Attach the medium-sized rubber feet to the bottom of each foot on the module. The rubber 
feet provide increased stability and protection from scratches.
CAUTION:The Acoustimass module generates a magnetic field. Although this is not an 
immediate risk to your video tapes, audio tapes, and other magnetic media, you should not 
store any of these items directly on or near the module.
Keep the port and ventilation openings free and unimpeded:
• Choose a location that is convenient (under a table, behind a sofa or chair, screened by 
drapes) but will not block the ventilation openings of the module.
• Aim the port of the module into the room or along the wall. This prevents a blocked port or 
over-powering bass.
• Stand the Acoustimass module on its feet. Do not lay it on its side or stand it on either end 
(Figure 7).

Recommended orientation 
for the module
CAUTION:Do not block the openings on the back of the module, which provide ventilation
for the built-in circuitry.

Making the connections
The components of the 3•2•1 and 3•2•1 GS home entertainment systems are 
connected through the media center, using custom cables supplied with the system. The 
jacks on the rear of the media center are labeled (Figure 9), to help get everything hooked up 
right the first time.

rear of the media center
CAUTION:Do not plug the music system into an AC power (mains) outlet until all the 
components are connected.
Additional cables
If additional audio cables or longer cables are needed to make these connections, contact 
Bose. Before you call, refer to the list of offices included in the product carton.
Connecting the 3•2•1 speakers
1. Insert the single-plug end of the speaker cable into the SPEAKERS connector on the rear 
panel of the media center (Figure 10). Tighten the screws on either side of the plug.

Attaching the supplied antennas
On the rear panel of the media center there are jacks for AM and FM antennas (Figure 15).
Unwind the wires for each antenna to provide the best reception.
Note:An outdoor antenna may be used in place of the two that are supplied. To add an 
outdoor antenna, consult a qualified installer. Follow all safety instructions supplied with the 
antenna.
Figure 15
Adding the AM and FM 
antennas
FM antenna
Plug the connector into the FM antenna jack on the media center rear panel. Spread out the 
antenna arms at the other end and move them around to establish optimum FM reception. 
Extend the antenna as far from the media center and other external equipment as possible.
AM antenna
1. Plug the connector into the AM antenna jack on the media center.
2. Move the antenna loop as far as possible, at least 20 inches (50 centimeters) from the 
media center and at least 4 feet (1.2 meters) from the Acoustimass
® module. Experiment 
with positioning the loop for optimum AM reception.
3. Follow the instructions enclosed with the AM loop antenna to stand it on the supplied 
base, or mount it to a wall.
Connecting cable FM radio
Some cable TV providers make FM radio signals available through the cable service to your 
home. This connection is made to the external FM jack on the back panel of the media center. 
To connect to this service, contact your cable TV provider for assistance.
Note:Make sure that the cable radio installation includes a TV/FM splitter so that only the 
FM radio band, not the cable TV band, is received by the media center. If necessary, contact 
your cable company.

Connecting your TV to the media center
Note:If you will be using the 3•2•1 home entertainment system with both a TV and a VCR, 
skip this section and go to “Connecting your TV and VCR to the media center” on page 19.
Note:If your TV does not have an audio output jack, see “If your TV does not have audio out-
put jacks” on page 21.
1. Attach one end of the supplied video cable (yellow) to the VIDEO OUTPUT jack on the 
back of the media center (Figure 16).
2. Attach the other end of the video cable (yellow) into one of the video input jacks on your 
TV. 
3. Locate the AUDIO INPUT jacks on the back of the media center. Under the AUDIO INPUT 
heading, there are jacks labeled VIDEO 1, VIDEO 2, and AUX.
4. Attach the supplied stereo cable to the media center by inserting the white plug into the 
jack labeled VIDEO 1 (L), and the red plug into the jack labeled VIDEO 1 (R).
5. Attach the other end of the stereo cable to the TV by inserting the white plug into the

Make note of the video input jack you use
Most TVs have several video input jacks (for example: Video 1, Input 1, or Aux). 
When you connect the yellow video cable to one of these jacks, make note of the name of 
the jack you choose. You will need to select the corresponding video input setting on your 
TV in order to play a DVD. See “Selecting the correct video input on your TV” below.
Selecting the correct video input on your TV
In order to play a DVD, your television must be set to receive signals from the correct video 
input jack. 
Most TVs have a TV/VIDEO, INPUT, or AUX IN button for selecting the video input. When 
the TV is on, the display “VIDEO 1”, “VIDEO 2”, or “AUX” will usually appear in a 
corner of the screen to indicate which video input is currently selected.
Before playing a DVD, locate the name of the video input jack (on the TV) that you have 
connected the yellow video cable to, then turn the TV on and select the video input (on the 
screen) that matches the name of that jack. If you are unable to select the correct video 
input setting on your television, please consult your TV’s owner’s guide.

S-video as an alternate means to connect to the TV
An S-video input jack, provided on many TVs, delivers a higher-quality TV picture than the 
composite video output connection shown in Figure 16 on page 17.
To make this alternate connection, insert the end of an S-video cable from the TV into the 
S-VIDEO OUTPUT on the media center. This cable may be purchased from your Bose
®dealer
or a local electronics retailer.
Note:Some older TVs with standard TV cable connectors do not have a composite video or 
an S-video input. Such TVs are not compatible with any DVD players and require use of an RF 
modulator for this connection, which is available at your local electronics store.
Note:If you use S-video to connect your cable box to the media center, you must also use 
S-video to connect all other components (such as the TV and VCR) to the system. 
Turning off the internal speakers in your TV
When you listen to TV audio through your 3•2•1 home entertainment system, the speakers in 
your TV should not be on. Use the on-screen menu on your TV to locate the setting for 
INTERNAL SPEAKERS and select OFF. (Refer to your TV owner’s guide for instructions). 
Note:In some models, when the TV’s internal speakers are turned off, you may need to turn 
up the TV’s volume by 75% to 100% in order to hear audio from the 3•2•1 home 
entertainment system. (See your TV owner’s guide for details.)
If your TV does not have an option to turn off the internal speakers, reduce the volume on 
your TV to its lowest setting.
