Fine-tuning your system In most situations, you only need to follow the speaker placement guidelines (see "Setting Up" on pages 6 and 7) for your system to provide excellent sound quality. You do not need to adjust tone settings for changes in volume, since Bose° patented, automatic dynamic equalization 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. Figure 17 Bass and treble controls Adjusting speaker controls The Companion powered speaker system TREBLE and BASS controls are located on the bass module. 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 +). Bass module placement affects the amount of bass you hear. Placing the bass module closer to the comer of the room will increase bass. Moving the bass module away from the corner will decrease bass. 19
