[. . . ] (Save the carton and packing materials in case you ever want to ship the system. ) If any parts appear damaged, do not attempt to use the system. Repack all parts in the original carton and notify your authorized Bose dealer immediately. Figure 1 What the carton contains Acoustimass module Two cube speakers Four (4) adhesive-backed rubber feet Four (4) speaker cables, 20 feet long Selecting locations for the cube speakers You can place the cube speakers anywhere from 3 to 15 feet (0. 9 - 4. 6 m) apart. For the most natural sound in average sized rooms, place them 6 to 12 feet (1. 8 - 3. 7 m) apart. Magnetic shielding allows you to place them close to a video screen without causing interference. [. . . ] For more information or to order accessories, contact your Bose dealer or call Bose Customer Service directly. Refer to the list of phone numbers inside the back cover. 4 Setting Up Your Acoustimass® 3 Speaker System Selecting a location for the Acoustimass module ® English The Acoustimass module can be hidden almost anywhere in a room. Leave at least 2 inches (5 cm) of space between the opening (port) and the wall. To prevent interference, keep the module at least 2 feet (0. 6 m) from any video screen. For a balanced sound in most rooms, place the module along a wall within 5 feet (1. 5 m) of the corner. To increase bass response, move the module closer to a corner without blocking the opening. To decrease the bass, place the module farther from the corner. Note: When you decide how you will position the module, attach the rubber feet to the bottom surface to protect the module and the floor.

CAUTION: Be sure all components are turned off and unplugged from the power outlet before making the connections. To place these components more than 20 feet (6. 2 - 9. 2 m) apart, you will need to splice in a length of 18-gauge speaker cable. To place them more than 30 feet (9. 2 m) apart, you will need heavier gauge wire. (See the wire recommendations on page 10. ) You can get additional speaker cable at electrical and hardware stores or by calling Bose Customer Service. (See the list of phone numbers inside the back cover. ) Speaker cables consist of two insulated wires. Make sure the cube speakers are connected to the module and not directly to the amplifier or receiver. 7 Operating Your Acoustimass® Speaker System Checking the system English Make sure your system is working properly by following these steps: 1. You should hear music from the left cube speaker only, although you may detect a faint sound from the other cube speaker. Now you should hear music from the right cube speaker only, although you may also hear a faint sound from the left cube speaker. Compare that sound to what you hear with the balance control in the far left position. Then compare the sound in the center balance position with sound when the control is in the right position. Be sure to return the balance control to the center position when you are finished. If your system does not respond as described, check all the wires for proper positive to positive and negative to negative connections. If your system still doesn't respond properly, see "Troubleshooting" on page 9. Understanding automatic system protection When played at high volume, the Acoustimass® 3 system's automatic protection circuit activates to prevent damage to the system from electrical stress or overload. When this happens, you may notice a slight decrease in volume, which is normal. Setting the volume at or above this level for sustained periods is not recommended. 8 Maintaining Your Acoustimass® Speaker System Cleaning your speakers Clean the cabinets of your Acoustimass® 3 system using a damp cloth. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. [. . . ] Do not allow liquids to spill through the speaker grilles or enter the Acoustimass module. To avoid damaging the drivers located directly behind the grille cloth, use light pressure only. English Troubleshooting If you have a problem with your Acoustimass 3 speaker system, turn off the amplifier or receiver and check all the connections between the cube speakers, the module, and amplifier or receiver. Since problems are likely to originate with components other than speakers, you may want to refer to your amplifier or receiver owner's guide. Problem The left cube speaker does not play or sounds distorted. What to do · Disconnect both speaker cables from the amplifier or receiver. Reconnect the cable from the bass module's L INPUTS to the amplifier or receiver's RIGHT speaker terminals. [. . . ]
