Adjusting speaker controls
The Lifestyle® 40 music system treble and bass controls are located on the Acoustimass® module (Figure 32). 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
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 33). 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.
