Bose Acoustimass 3 Series II Owner's guide - Page 6

Where to Place the AcoustimasseModule. You can place the Acoustimass module almost any where in your listening room (Figure 1)-even Ounder a bed or table or behind a sofa-and in ther a vertical or horizontal position (Figure 4). ust be sure not to block the two slotted openings in the end of the unit, and leave at least 2 inches (approximately 5 cm) of open space between these openings and the wall or other surface. NOTE: While the cube arrays are shielded, the Acoustimass module is not shielded and should always be placed at least 2 feet from any monitor or television. The unique Acoustimass speaker technology of the Acoustimass•3 system delivers room-filling bass from almost anywhere. The most bass is generally produced with the module playing in the corner of a room. You can fine-tune the level of the bass simply by changing the location of the module within your room. Generally, we recommend that you place the module along a wall, not more than 5 fed (approximately 1 to 1.5 meters) from a corner. This provides a normal balance of frequencies from your Acoustimass•3 system. To increase the amount of bass, move the module closer to the walls and/or corners of your room. Or, to get less bass, move the module toward the center of your room. It should be reasonably easy to find a location that is both •onvenient and provides a pleasing level of bass. Room Acoustics. The acoustics (sound properties) of your listening room can affect the o✓erall sound quality of any speaker system, including your Acoustimass•3 system. In general, you can solve many acoustical problems by careful use of the tone controls on your amplifier or receiver. However, these controls may put greater power demands on your receiver or amplifier, especially if you turn them all the way up. Although your Bose* koustimass-3 system incorporates automatic protection circuitry that guards against most types of electrical stress, excessive tone control use can cause an amplifier or receiver to run out of power and distort, potentially damaging your system. Below are some common acoustical problems and tips for controlling them: 1. Not enough treble sound (high freguen- cies)- Rooms with a lot of sound absorbing furnishings such as stuffed furniture, walltowall carpet or heavy drapes may reduce the high frequencies from your koustimasse-3 system. Slightly turn up the treble control on your amplifier or receiver. Or, if you prefer, remove some of the sound absorbing furnishings from the room. 2. Too much treble sound-Rooms with too few sound•absorbing furnishings, especially those with bare floors and walls, may sound overly shrill or "bright!' Turn down the treble control or add throw carpets or drapes to absorb the sound. 3. Too much or too little bass (low frequencies)-Adjust the bass control on your ampliher or receiver, or move the Acoustimass module closer to or away from a wall and/or corner as described in the preceding section. External signal processors (such as graphic and parametric equalizers), although not recommended, can be used with your Acoustimass•3 system if you want a greater degree of acoustic control. Consult your Bose dealer for advice. Maintaining Your System You can easily clean the module and cubes of your Acoustimass-3 system with a damp cloth and, if necessary, a mild detergent such as dish soap. You may prefer to remove the grilles to clean them, as the drivers are located directly behind the grilles and can be easily damaged. Do not allow liquids to spill through the grille assemblies of the cube speaker or to enter the Acoustimass module in any way. 5
