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. Figure 20 Bass and treble controls 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 Treble speaker system. In general, you can reduce many problems with acoustics by the cautious Bass 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.
