Important Safety Instructions
Antenna grounding
Example of antenna grounding as per National Electrical
Code, ANSI/NFPA 70.
Note to CATV system installer
This reminder is provided to call the CATV system
installer’s attention to Article 820-40 of the NEC (of USA)
that provides guidelines for proper grounding. In particu-
lar, it specifies that the cable ground shall be connected
to the grounding system of the building, as close to the
point of cable entry as is practical.
18. Use proper power sources – Plug the product into
a proper power source, as described in the operating
instructions or as marked on the product.
19. Avoid power lines – Use extreme care when
installing an outside antenna system to keep from
touching power lines or circuits, as contact with
them may be fatal. Do not install external antennas
near overhead power lines or other electric light or
power circuits, nor where an antenna can fall into
such circuits or power lines.
20. Ground all outdoor antennas – If an external
antenna or cable system is connected to this
product, be sure the antenna or cable system is
grounded. This will provide some protection against
voltage surges and built-up static charges.

Before you begin
Thank you for purchasing the Bose® Lifestyle® 12 system. This complete audio home enter-
tainment system offers superb sound, elegance, technology, and simplicity for music and
home theater.
Your system includes:
•A Lifestyle
® music center with built-in AM/FM radio and compact disc (CD) player
•Inputs for a video sound source, an auxiliary source, and a tape deck
•Powered Acoustimass
® speakers with a hide-away Acoustimass module
•An easy-to-use remote control
Bose Videostage
® decoder technology enables the Lifestyle® 12 system to reproduce the
realism of movie sound especially for a home environment. When a movie soundtrack or CD
is produced in a surround sound format, specially encoded sound is sent to any or all of the
available speakers. Dialogue is usually sent to the front speakers. Sounds from the left or
right side of the picture are sent to left or right front speakers. Ambient sounds or special
effects may be sent to the surround (rear) speakers. Bose Videostage circuitry automatically
directs the sound to the correct speakers.
To select surround-encoded material, look for any of the terms Surround, Dolby Surround,
and the double-D symbol 
 * on tapes and discs, and the word “surround”
preceding a TV broadcast.
When sound is recorded in stereo, but not surround-encoded, Videostage decoder technol-
ogy directs it to the most appropriate speakers based on the signals received. When viewing
older movies or listening to other monaural programs on your Lifestyle
® 12 system,
Videostage circuitry directs sound so it appears to come from the center of the TV screen.
You can listen to any program material in SURROUND (5-speaker) mode, whether the
program is surround-encoded, stereo, or monaural. You will not hear sound from all five
speakers all of the time. Even with surround-encoded material there are times when no
sounds are directed to the surround speakers. You can select the speaker mode that sounds
best to you for each particular program.

Setting Up
Select the locations for your Lifestyle® 12 system
When you place your speakers according to the guidelines below, a combination of reflected
and direct sound provides the audio atmosphere of a home theater. You may experiment with
the placement and orientation of the cubes to produce the sound most pleasing to you. For
the best surround effect, adjust the speakers so you cannot pinpoint where the sound comes
from. It is preferable not to aim the cubes directly at the listener. For more discussion of
speaker placement and room acoustics, see “Fine-tuning your system” on page 23.
Speaker locations
Follow these guidelines to select locations that provide the maximum home theater effect
from your Lifestyle® 12 system (Figures 2 and 3).
CAUTION: Choose a stable and level surface for your speakers. Vibration can cause the
speakers to move, particularly on smooth surfaces like marble, glass, or highly polished
wood. For additional stability, you can add rubber feet to your speakers. You may obtain
rubber feet (part no. 178321), free of charge, from Bose
®. Contact Bose Customer Service
(see listings on the inside back cover).
Left and right front speakers
The sound from the left and right front speakers should seem to appear at the edge of the
picture, so that the acoustic image is close to the size of the visual image (Figure 2). The front
speaker cables allow up to 20 feet (6.1 m) distance from the Acoustimass
® module.
1. Place the cubes on line with the horizontal center of the TV screen.
2. Place them up to 3 feet (1 m) from the edge of the TV screen.
We recommend a maximum distance of 3 feet (1 m) so that the sound does not become
too separated from the picture. You may wish to vary this distance based on room condi-
tions and personal preference.
3. Direct one cube of each array forward. Direct the other cube toward the wall or in a
different direction to create reflected sound. (See the illustration of reflected sound pat-
terns in Figure 3.)
Note: The cube speakers are magnetically shielded so you can place them close to the
TV without affecting picture quality.
 
						

							AM191409_01_V.pdf   December 20, 2001 7
Center speaker
The sound from the center speaker should appear to come directly from the center of the
picture (Figure 2). The center speaker cable allows up to 20 feet (6.1 m) distance from the
Acoustimass
® module.
1. Place the speaker on line with the vertical center of the screen, above or below (which-
ever is closer to the screen), or the closest convenient location.
2. Place the speaker in line with the front of the screen (not pushed to the back of the TV).
3. Direct each of the cubes slightly away from center, to create a wider area of direct sound
(Figure 3).
Note: If you put the speakers in a bookcase unit, be sure to place each one at the front
edge of the shelf. Placing speakers in an enclosed space can change the tonal quality of the
sound. This effect is minimized if the shelves are filled with books.

Center
Surround speakers
The surround (rear) speakers create an area of sound around the listener. Place them in the
back half of your room. Direct the cubes so that you do not pinpoint the exact location of the
sound source (Figure 3). The surround cables allow up to 50 feet (15.2 m) distance from the
Acoustimass module.
Figure 3
Speaker placement
1. Place the speakers at ear height or higher, if possible.
2. Direct the cubes to reflect sound off one or more surfaces.
3. Do not direct the sound straight at the listener.

Setting Up
Acoustimass
® module
Follow these guidelines to select a location for the Acoustimass module.
Note: To avoid interference with the TV picture, place the Acoustimass module at least
18 inches (45 cm) from the TV.
1. Place the Acoustimass module along the same the wall as the TV, or close to the same
end of the room as the front speakers (see the example along the front wall in Figure 3).
2. Select a convenient location – under a table, behind a sofa. Do not allow furniture or
drapes to block the ventilation openings of the module.
3. Place the Acoustimass module within reach of the audio input cable, speaker cables, and
an AC power (mains) outlet.
4. Select a position for the Acoustimass module (Figure 4). For proper ventilation, place it on
the long edge, with the connectors facing the floor. An alternate position is on its largest
side, with the bass and treble controls facing up. Do not place the module on either end,
as shown by the last two views in Figure 4.

5. Once you have selected a position for the module, place the four self-adhesive rubber feet
near the corners of the bottom surface. The rubber feet provide increased stability and
protection from scratches.
6. Aim the port (the round opening) into the room or along the wall to avoid blocking the port
or creating too much bass.
7. For best bass performance, do not place the port at equal distances from any two walls or
from a wall and the ceiling.
CAUTION: Do not cover the ventilation openings of the Acoustimass module. The slots on
the end provide ventilation for the built-in electronic circuitry, and should not be blocked.
Music center
Select a location for the music center.
1. Allow enough room to open the CD player cover.
2. Place the music center close enough to the sound sources (TV, VCR, etc.) to allow for
cable length. If you need additional audio and/or video cables to connect all of your
components, see your dealer or call Bose
®.
3. Place the music center within 30 feet (9.1 m) of the Acoustimass module (the length of the
audio input cable).
