Connecting power to your system CAUTION: If you purchased a dual-voltage system, it is important that you set the speakers to the correct voltage. To do this, refer to "Selecting the correct voltage" on page 6. Follow these steps to connect power to your Acoustimass powered speaker system: 1. Plug the power cord from the Acoustimass module into an AC power (mains) outlet. Insert the power cords of the Lifestyle® system into an AC power (mains) outlet. Turn Acoustimass module power switch to the ON position. Operating in more than one room Your Lifestyle® PersonalTM music center can control up to four sets of Bose® powered speakers, allowing your family to enjoy four different audio sources (CD, radio, TV, etc. ) in up to four rooms. These rooms are referred to as room A, B, C, and D, with room A being the primary room (the one used for a one-room system). If two or more rooms are connected to your system, the Personal music center displays ROOM and HOUSE buttons, and room indicators (A, B, C, and/or D). [. . . ] In the normal setting, the dots on each control are in the 12 o'clock 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 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. 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 ­). [. . . ]
