Operating Your Lifestyle® 12 System
Listening to your Lifestyle® 12 system
Your Lifestyle® 12 system offers the option of listening in 2, 3, or 5-speaker mode. The system
turns on in SURROUND (5-speaker) mode when VIDEO is selected and in STEREO (2-
speaker) mode for AM/FM, CD, TAPE, or AUX. You can change to the speaker mode that
sounds best to you for each particular program.
You can listen to any program material in SURROUND mode, whether the program is sur-
round-encoded, stereo, or monaural. You will not hear sound from all 5 speakers all of the
time. Even with surround-encoded material there are times when no sounds are directed to
the surround speakers. For most video material (mono, stereo, or surround), listening in 3 or
5-speaker mode helps anchor the dialogue to the picture while providing a fuller sound. See
additional discussion about selecting program material on page 4.
The system’s Videostage
® decoding technology directs the sound from surround-encoded
program material to the appropriate speakers to create the home theater effects. Monaural
program material is directed to the front speakers, primarily the center. For stereo material,
sounds encoded as left are directed to the left front, right to the right front, and both left and
right directed primarily to the center. Some sounds which are not specifically left or right may
also be directed to the surround speakers. Decide if the particular material sounds better to
you in 3 or 5-speaker mode.
Adjusting the volume
•Use the VOLUME  (up) or  (down) keys to raise or lower the volume.
•For SURROUND mode, use the SURROUND 
+ or –  keys to raise or lower the sound
level directed to the surround speakers.
•For STEREO+CENTER mode, use the SURROUND 
+ or –  keys to raise or lower the
sound level directed to the center speaker.
Turning the system off
•Press the OFF key on the remote or the console.
•To turn off your music system automatically after 15 minutes, press the AUTO OFF key on
the remote. Each additional press of AUTO OFF increases the time until shutoff by 15
minutes (up to 75 minutes). The display indicates AUTO OFF is set and flashes the amount
of time set.
Listening to video sound
Turning the video components on
Turn on the TV, VCR, laserdisc, DVD, or CDI player, or other video source. If you are viewing
video from a VCR, laserdisc, DVD, or CDI player, load a tape or disc.
Turning the system on and choosing video sound
Press the VIDEO key on the remote or the console to turn your music system on to play video
sound. The system turns on in SURROUND mode.
If your video component is connected to the music center AUX or TAPE jacks, press AUX or
TAPE to select the source. The system turns on in STEREO mode. Select SURROUND or
STEREO+CENTER mode, if desired.
Using enhanced bass for movie soundtracks
Pressing VIDEO turns the system on in enhanced bass mode, a bass level specially designed
for proper playback of movie soundtracks. Press VIDEO again to alternate between enhanced
bass for movies and standard bass for other listening.
Pressing AUX or TAPE turns the system on in standard bass mode. Press AUX or TAPE again
to alternate between standard bass for other listening and enhanced bass for movies.
Note: You may not hear a difference between enhanced and standard bass when listening
to movie soundtracks that do not have much very low bass content.

Maintaining Your Lifestyle® 12 System
Fine-tuning your system
In most situations, you only need to follow the speaker placement guidelines (see “Setting
Up” on pages 6-8) for your system to provide excellent sound quality.
You do not need to adjust tone settings for changes in volume, since Bose
® patented signal
processing technology provides a natural tonal balance over the full range of volume settings.
If desired, you can further fine-tune your system as described here.
Adjusting speaker controls
The Lifestyle® 12 system TREBLE and BASS controls are located on the Acoustimass®
module (Figure 21). They allow you to adjust the treble (high frequencies) and bass (low
frequencies). In the normal setting, the dots on each control are in the 12 o’clock position.
You can also locate the normal setting by feeling when the control settles into the notch at
this position. Turn the controls clockwise to increase, and counterclockwise to decrease, the
amount of treble or bass.
Compensating for room acoustics
The acoustics (sound qualities) of your room can affect the overall sound quality of any
speaker system. In general, you can reduce many problems with acoustics by the cautious
use of the TREBLE and BASS controls.
Too much or too little treble
Rooms with too few sound-absorbing furnishings, especially those with bare floors and walls,
may sound overly shrill or “bright.” Turning down the treble control (toward –)
decreases treble sound.
Rooms with a lot of sound-absorbing furnishings, such as upholstered furniture, wall-to-wall
carpet, or heavy drapes, may reduce the treble sound of your system. Moving speakers
further away from soft furnishings increases treble. You can increase treble sound by slightly
turning up the treble control (toward +).
Too much or too little bass
You can decrease bass sound by turning down the bass control (toward –). To increase bass,
turn up the bass control (toward +).
Acoustimass module placement affects the amount of bass you hear. Placing the module
closer to the corner of the room increases bass. Moving the module away from the corner
decreases bass.
Compensating for movie soundtracks
When a movie soundtrack is played in a motion picture theater, its bass is restored to the full
level intended by the movie’s sound designer. To perform the same way in your home, your
Lifestyle
® 12 system restores the bass to this level when you select VIDEO. In VIDEO, AUX, or
TAPE mode, you can choose between standard and enhanced bass.
In VIDEO mode, the system turns on enhanced bass for movies. Press VIDEO again to
change to standard bass.
In AUX or TAPE mode, the system turns on in standard bass. Press AUX or TAPE again to
change to enhanced bass for movies.

Maintaining Your Lifestyle® 12 System
Changing the house code settings
Each Lifestyle® remote control uses a system of matching house codes to communicate with
its corresponding music center. If your remote’s commands ever conflict with those of
another nearby Lifestyle
® system, you can easily set a new house code for your system and
its remote control(s) by following the procedures below.
1. Open the remote control battery cover.
2. Locate the miniature switches (Figure 22). Change the position of switch 2, 3, or 4 by
moving it in the opposite direction from its current setting.
Note: Do not change any other switches at this time.
3. Replace the battery cover on the remote control.
4. Press the OFF key on the console.
5. Open the CD cover.
6. Press the STORE key. The display will begin to flash ‘— —’.
7. Within two seconds while the display is flashing, press any key on the remote control.
The display stops flashing and momentarily shows ‘— —’ to confirm recognition of the
house code. The system will remain off.
8. If you have additional remote controls, open the battery cover of each one and change the
switches to match those of the first remote control. It is not necessary to repeat steps 4–7.

Adding speakers
Your Lifestyle® 12 system provides high quality audio for a single listening area. However, your
music center also provides connections (SPEAKERS A or SPEAKERS B) for adding a pair of
powered speakers in a second room. In the second room, you can listen to the sound source
that is playing in the main room.
You can purchase an additional remote control to keep in the second room.
Keep the following considerations in mind if you choose to connect secondary speakers.
Using speakers connected to the B outputs:
•You must use a second remote control, set to B (see instructions below), to turn on the
B speakers.
•Adjusting volume with this second remote adjusts volume for only the B speakers.
•Using the mute key on the second remote mutes or unmutes the second room speak-
ers.
Using speakers connected to the A outputs:
•The music center controls operate speakers connected to FIXED and A outputs.
•Adjusting volume from the music center control panel or with the remote control that
came with the system adjusts volume for speakers connected to FIXED and A outputs.
•Using the mute key on the main remote mutes or unmutes speakers connected to
FIXED and A outputs.
Setting a second remote for additional speakers
You need a second remote control, set to B, to operate speakers connected to the
SPEAKERS B outputs. When you purchase a second remote control, it is shipped set to A, to
control your main speakers. It will also control secondary speakers connected to
SPEAKERS A.
To set your second remote to control speakers connected to B, follow these steps:
1. Open the remote control battery cover.
2. Locate miniature switch 5. Slide the switch down (Figure 23).
3. Locate miniature switch 6. Slide the switch up (Figure 23).
4. Make sure that the house code switches match those on your first remote (see page 20).
5. Replace the battery cover on the remote control.
Note: Switches 7 and 8 are not for current system use.
