User manual BOSE ACOUSTIMASS 3 III

[. . . ] The tiny cube speakers fit almost anywhere, while the Acoustimass module is designed to be hidden behind drapes, under furniture, or in the corner of the room. Unpacking the system Unpack the system carefully. Avoid setting the module down on its connection panel, which could scratch a surface. (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. [. . . ] 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. The insulation around one wire is marked with a band or stripe. This marked wire is always positive (+). The plain wire is always negative (­). These correspond to the red (+) and black (­) terminals on the back of the speaker, amplifier, or receiver. Be sure to connect each wire to the proper terminal (positive to positive, negative to negative). 5 Setting Up Your Acoustimass® 3 Speaker System Connecting the cube speakers to the Acoustimass module ® English Use the following steps to connect the cube speakers to the rear panel of the Acoustimass module: 1. Turn the balance control on your amplifier all the way to the left. You should hear music from the left cube speaker only, although you may detect a faint sound from the other cube speaker. Turn the balance control all the way to the right. Now you should hear music from the right cube speaker only, although you may also hear a faint sound from the left cube speaker. Now play music that includes some deep bass passages. Listen with the balance control in the center position. 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. The bass should be the same or louder with the control in the center. 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. [. . . ] 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. Set the amplifier or receiver's balance control all the way to the right and turn on the power. [. . . ]
