The Lifestyle® remote control
The advanced radio-frequency remote control works from anywhere within most types
of home construction; its radio wave signals pass through walls and floors to reach the
music center. Simply press the desired button. You do not need to aim the remote at the
music center.
Note: Some types of buildings create “dead spots” where the remote will not operate.
Simply move the remote a foot or two and try again. You can also move the music center a
few feet to a location with better remote response.
Figure 19 shows the layout of the remote control.
Special buttons on the remote control select the speaker mode (5, 3 or 2 speakers), and
adjust the surround (rear) volume and the center speaker volume.

Listening to your Lifestyle® 12 system
Your Lifestyle® 12 system uses digital signal processing to bring even greater realism and
impact to both movies and music recordings. Built-in Dolby Digital decoding delivers up to
5.1 discrete audio channels (i.e., five for the independent cube speaker arrays and one for
rich bass from the Acoustimass
® module) from DVD, digital TV, next-generation cable boxes,
and satellite receivers. With analog formats, as well as for two-channel PCM and Dolby
Digital bitstreams, 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.
In addition, Videostage decoding processes a one-channel program and directs five-channel
sound to five independent speakers. Dialogue remains locked on-screen, while music and
ambient effects fill the room to increase your listening enjoyment.
Your Lifestyle
® 12 system offers the option of listening in 5, 3, or 2-speaker mode. The system
turns on in SURROUND (5-speaker) mode. For most video material (mono, stereo, or sur-
round), listening in 5 or 3-speaker mode helps anchor the dialogue to the picture while
providing a fuller sound.
Using enhanced mode for movie soundtracks
Pressing VIDEO or AUX turns the system on in enhanced mode, with bass and treble settings
specially designed for proper playback of movie soundtracks. Press the same button (VIDEO
or AUX) again to alternate between enhanced mode for movies and standard mode for other
listening. Pressing TAPE turns the system on in standard mode. Press TAPE again to alternate
between enhanced mode for movies and standard mode for other listening.
Note: Enhanced mode provides more bass and less treble, as is specified for proper
playback of movie sound.
Digital Dynamic Range® compression
Digital Dynamic Range® compression automatically 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., an explosion). This feature is engaged when you turn on the system but
you may turn it on (one chime) or off (two chimes) using the STEREO 
STEREO (2-speaker)
button.
Using simulated surround for mono movie material
Bose® Videostage decoding can process a one-channel program into five-speaker sound –
directing the signals so that dialogue remains locked on-screen, while music and ambient
effects fill the room. You experience a surround sensation, providing extra enjoyment when
you watch older (i.e., pre-stereo) movies. This feature can be used for mono TV, FM, and AM
programs. Press the SURROUND 
SURROUND (5-speaker) button to turn it on (one chime) or off (two
chimes). This feature is automatically engaged when a Dolby Digital bitstream indicates that it
contains a mono program.

Selecting listening material
To select material with compatible digital-audio bitstreams, look for the terms PCM or Dolby
Digital, or the symbol

Dolby Surround, the symbol 
3 on tapes and discs, or the word “surround” preced-
ing a TV broadcast. You can listen to any program material in SURROUND (5-speaker) mode,
though you may not hear sound from all five speakers all the time. Some monaural and stereo
materials will not cause sound to be directed to the surround speakers. Even with surround-
encoded material there are times when no sounds are directed to the surround speakers.

button on the Lifestyle
® remote control or music center to raise or lower the volume. Control
all other functions at the source, referring to its owner’s manual if necessary. To begin, make
sure the component is turned on and a tape, CD, DVD, laserdisc, etc. is loaded.
   Note: The Lifestyle® 12 system cannot turn a connected component on or off.
Turning the system on and selecting the component

Maintaining Your Lifestyle® 12 System
Fine-tuning your system
In most situations, following the speaker placement guidelines (see pages 6-8) provides
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 below.
Adjusting speaker controls
The Lifestyle® 12 system TREBLE and BASS controls are located on the Acoustimass®
module (Figure 20). 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.

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 21). 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 music center.
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.
