Setting Up
Before you begin
Thank you for purchasing the Bose® Lifestyle® 25 Series II system. This complete audio home
entertainment system offers superb sound, elegance, technology, and simplicity for music
and home theater. Your system is fully compatible with digital program material and includes:
•A Lifestyle
® music center with built-in AM/FM radio and six-disc CD changer
•Inputs for two video sound sources, a digital sound source, and a tape deck (or other
auxiliary source)
•Capability for operating two listening zones
•Powered Acoustimass
® speakers with a hideaway Acoustimass module and five cube
speaker arrays
•An easy-to-use remote control
Realism and impact
Your Lifestyle® 25 Series II home theater system is equipped with an all new Videostage®
decoder that uses digital signal processing. The result is increased surround sound realism
and impact both for movie soundtracks and music recordings. Built-in Dolby Digital decoding
of inputs from DVD, digital TV, next-generation cable boxes, and satellite receivers provides
“5.1” capability – up to five discrete audio channels directed into five independent cube
speaker arrays, plus rich bass sound from the Acoustimass module. The Videostage decoder
processes analog formats, as well as two or even single-channel PCM and Dolby Digital
bitstreams, and helps to deliver the acoustic experience of the movies right in your home.
Compatibility
Your system is fully compatible with:
•Digital-audio bitstreams. Look for the symbol 
1 or the terms Dolby Digital or
PCM on DVD-Video discs. Your Lifestyle® 25 Series II system cannot process MPEG-2
or DTS digital bitstreams.
•Surround-sound sources such as VCRs, stereo TVs, cable boxes and satellite
receivers. Videostage decoding directs stereo information to the surround channels, so
the sound of stereo broadcasts and rented or recorded tapes can approach that of
your DVD discs.
•Surround-encoded analog or digital audio signals. Look for the terms Surround or
Dolby Surround, or the symbol 
3 on tapes and discs, or the word “surround”
preceding a TV broadcast.
•Stereo program material from TV, FM, CD, and cassette. Videostage decoding
delivers five channels, even when the original source contained only one or two.
•Monaural program material. Videostage decoding can process a one-channel
program into five-channel sound and direct the result to five independent speakers.
Dialogue remains locked on-screen, while music and ambient effects fill the room.
Automatic sound level monitoring and control
Your enjoyment of movies at home is enhanced by Digital Dynamic Range® compression. This
technology automatically monitors and adjusts the volume to allow you to hear soft sounds,
particularly dialogue, and to prevent you from being overwhelmed by a loud special effect
(e.g., a crash or explosion). This feature is especially useful for late night movie viewing – it
eliminates the need for you to constantly adjust the volume level. (See pages 22-23.)

Setting Up
Selecting the locations for your Lifestyle® 25 Series II 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
more discussion of speaker placement and room acoustics, see “Fine-tuning your system”
on page 29.
Speaker locations
Follow these guidelines to select locations that provide the maximum home theater effect
from your Lifestyle® 25 system (Figures 2 and 3).
CAUTION: Choose a stable and level surface for your speakers. Vibration can cause the
cube speakers to move, particularly on smooth surfaces like marble, glass, or highly polished
wood. If you are placing the center speaker on top of the television, use the smaller of the two
sets of rubber feet provided. You may obtain additional rubber feet (part no. 178321), free of
charge, by contacting 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).
1. Place the cubes so that they line up with the 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. The front cables allow the cube speakers to be placed up
to 20 feet (6.1 m) from the Acoustimass module.
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.
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 center speaker directly above or below the center of the TV screen, or at the
closest convenient location.
2. Align the speaker with the front of the TV 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.

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 cannot 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.

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 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.
CAUTION: The magnetic field from the Acoustimass module is not an immediate risk to your
video tapes, audio tapes, and other magnetic media. However, you should not store tapes
directly on or near the Acoustimass module.
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, DVD player 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).
