Operating Your Lifestyle ® 50 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 integrated signal process-
ing 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 ® 50 system treble and bass controls are located on the Acoustimass ® module
(Figure 39). 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 careful use
of the treble and bass controls.
Too much or too little treble
Rooms that reflect a lot of sound, 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 sound muffled or dull. 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 also 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.
Optimizing AM/FM radio reception
You can adjust the orientation of your AM/FM antenna for the strongest signal by selecting
SIGNAL LEVELS with the MENU button (Figure 40). Select the AM or FM radio, and the
display shows you the strength level of the received signal. While watching the display,
reposition your antenna until the highest possible signal level is achieved. The signal level can
vary from 0 to 99. The manual tuning keys are provided so that you can check the signal
strengths of multiple stations.
