Setting Up Your Acoustimass® 3 Speaker System

Before you begin

Thank you for purchasing the Bose® Acoustimass® 3 speaker system. Its quality construction and advanced technologies result from years of ongoing research at Bose.

Bose patented Acoustimass speaker technology delivers full, natural audio performance and, for all of the sound it produces, this Virtually Invisible® system takes up very little space. 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-backedrubber 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.

Bose mounting accessories, including wall/ceiling mounting brackets, floor stands, and table stands, add to your choice of where to place the cube speakers. 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.

Setting Up Your Acoustimass® 3 Speaker System

Selecting a location for the Acoustimass® module

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.

Figure 2

Choices on how to position the module

Using the cables correctly

Use the supplied cables to connect the cube speakers to the module and the module to your amplifier or receiver.

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-gaugespeaker 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).

Setting Up Your Acoustimass® 3 Speaker System

Connecting the cube speakers to the Acoustimass® module

Use the following steps to connect the cube speakers to the rear panel of the Acoustimass module:

1.Select one pair of wires, and locate the terminal tab on the rear of the left cube speaker.

2.Press the terminal tab on the back of the speaker and insert the marked wire into the red

(+) terminal and the plain wire into the black (–)terminal (Figure 3).

3.Release the terminal tab to secure both wires.

4.Repeat this process with the other pair of wires and the right cube speaker.

CAUTION: Do not connect your amplifier or receiver directly to the cube speakers. Cube speakers must be connected directly to the Acoustimass module or damage will result.

5.Locate the terminals marked OUTPUTS TO CUBE SPEAKERS on the rear panel of the Acoustimass module (Figure 4).

6.Connect the free end of the left cube speaker cable to the left (L) pair of terminals. Make sure that the marked wire is connected to the positive (+) terminal and the plain wire is connected to the negative (–)terminal.

7.Repeat step 6 for the right cube speaker cable, connecting its wires to the right (R) pair of terminals.

Figure 3

Connecting the Acoustimass module to your receiver or amplifier

Use the following steps to connect your Acoustimass module to your receiver or amplifier:

CAUTION: Correct wiring is important. Incorrect wiring will result in little or no bass output and could potentially damage the system.

1.Locate the terminals marked INPUTS FROM AMP OR RECEIVER on the rear panel of the Acoustimass module (Figure 4).

2.Connect either end of one of the remaining speaker cables to the left (L) pair of input terminals. Make sure that the marked wire is connected to the positive (+) terminal and the plain wire is connected to the negative (–)terminal.

3.Connect either end of the final speaker cable to the right (R) pair of input terminals. Make sure that the marked wire is connected to the positive (+) terminal and the plain wire is connected to the negative (–)terminal.

4.Connect the free end of the left (L) INPUTS cable to the LEFT speaker terminals of your amplifier or receiver. Connect the marked wire to the positive (+) terminal and the plain wire to the negative (–)terminal.

5.Connect the free end of the right (R) INPUTS cable to the RIGHT speaker terminals of your amplifier or receiver. Connect the marked wire to the positive (+) terminal and the plain wire to the negative (–)terminal.

CAUTION: Before you plug in your receiver or amplifier, make sure that no strands of wire from any terminal are brushing against any other terminal. Such “bridged” wires create short circuits which can damage your receiver or amplifier.

Operating Your Acoustimass® Speaker System

Checking the system

Make sure your system is working properly by following these steps:

1.Turn on your amplifier or receiver.

2.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. You should also hear the module.

3.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. You should also hear the module.

4.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. 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. It indicates that the power input may have exceeded safe levels. Setting the volume at or above this level for sustained periods is not recommended.
