Setting Up

Before you begin

The Bose® Acoustimass® 5 Series III speaker system offers many advantages over conventional speakers. For one, the system adjusts to deliver the best combination of direct and reflected sound for your listening environment and musical taste. And this Virtually Invisible® speaker system requires very little space to deliver a lifelike musical performance formerly associated withroom-dominatingloudspeakers.

Sections 1 – 5 give you step-by-stepinstructions on how to set up and connect the system to your components, so you can begin enjoying it as soon as possible. The remaining sections provide more detailed information on arranging your system for the best possible performance.

1. Unpacking the carton

Unpack your system and familiarize yourself with the parts identified in Figure 1. If any part of the product appears damaged, do not attempt to use the system. Repack it in the original carton and notify Bose or your authorized Bose dealer immediately.

Remove any staples from the opened carton flaps.

Remove the inner cartons containing the two cube speaker arrays.

Gently roll the carton over onto its side and then onto its opening.

Carefully lift the carton from around the Acoustimass module and packing cushions.

WARNING: The Acoustimass module weighs 18.8 pounds (8.5 kg). Use good lifting practice to avoid injury.

WARNING: To avoid danger of suffocation, keep the plastic bags out of the reach of children.

Note: Now is a good time to record the serial number of these speakers on page 3 of this guide and on your warranty card. It is a good idea to save all packing materials for possible future use.

Setting Up

2.Selecting the locations for your Acoustimass® system components

1.You can place the Acoustimass module almost anywhere in your listening room, in either a vertical or horizontal position (Figure 2). It can be hidden under a bed or table or even behind a sofa, as long as you remember not to block the round opening in the end of the unit. Allow at least 2 inches (5 cm) of space between that end and any surface. After selecting a place for the Acoustimass module, attach the four rubber feet to the bottom surface for additional stability. If you choose to stand the module on its connection end, the feet must be attached to protect the wire connections.

CAUTION: The Acoustimass module is not magnetically shielded and should be kept at least two feet (.6 m) from a television.

Figure 2

Acoustimass module positions

2.Next, select the positions for the left and right cube arrays. Remember that wires from the arrays connect to the Acoustimass module, so you should locate the cube arrays close enough to the module to enable the wires to reach it. The cube arrays are magnetically shielded, so they may be placed near a television.

Note: Bose® wall brackets and floor stands can increase your placement options. See page 12 for details and ordering information.

Note: While the wires provided are adequate for most installations, you may increase the distance between the cube arrays and the Acoustimass module by splicing in additional wire. If you do so, use similar gauge or thicker wire, and make sure you maintain the correct phase (+ to + and – to–),and properly connect the wires.

3. Examining the cables and connections

Locate the four identical pairs of wires packed with the system.

Two wire pairs connect your cube arrays to the Acoustimass module.

The other two wire pairs connect the Acoustimass module to your receiver or amplifier.

Examine the ends of the wires. The marked wire (with a red, striped, or printed marker) connects to the positive (+) terminal at each connection.

The cube arrays and the Acoustimass module have red positive (+) connections.

Connecting cube arrays to the Acoustimass module

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

4.Next, locate the terminals marked OUTPUTS TO CUBE SPEAKERS on the rear of the Acoustimass module (Figure 4).

5.Connect the other ends of the wires from the left cube array to the pair of terminals marked L. Make sure that the marked wire is connected to the positive (+) and the plain wire is connected to the negative (–)terminal.

6.Now, repeat step 5 for the right cube array, connecting its wires to the terminals marked R.

5.Connecting the Acoustimass® 5 Series III system to your receiver

1.Select one of the remaining two pairs of wires, and locate the left channel terminals on the Acoustimass module marked INPUTS FROM AMP OR RECEIVER. Depress the red, positive (+) tab, insert the marked wire and release the tab. Repeat the process for the black, negative (–)tab and the plain wire (Figure 5).

2.Then follow the same procedure for the right channel, using the last pair of wires.

3.Disconnect your receiver or amplifier from the AC power (mains) outlet.

4.Locate the speaker outputs on your receiver. Connect the other ends of the wire from the left channel of the Acoustimass module to the terminals marked L or LEFT. Make sure that the marked wire is connected to the positive (+) and the plain wire is connected to the negative (–)terminal.

5.Repeat these last two steps for the right channel.

6.Your set-upis complete. Plug in your receiver, turn the system on, and enjoy your Acoustimass 5 Series III speakers!

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.

Fine Tuning Your Acoustimass® 5 Series III Speaker System

Checking your speaker system

As you begin listening to your Acoustimass 5 Series III speaker system, the following test will help you determine that it is working properly:

A.Turn the balance control on your receiver or amplifier all the way to the left. If you have connected the cube arrays properly, you will hear the music from the left cube array, but not the right one. You may notice a very faint sound issuing from the right cube array, which is normal.

B.Now, turn the balance control all the way to the right. If your cube arrays are connected properly, this time you will hear music only from the right one. You may also detect a very faint sound from the other cube array.

C.Return the balance control to the center position. Play a musical selection with deep bass. Now turn the balance control all the way to the left and listen, and then turn the balance all the way to the right and listen. If the system is connected properly, the center position should exhibit the same or greater bass response than either the left-onlyorright-onlypositions. If it exhibits less, check to make sure that your components are connected as described on pages 6 and 7.

D.Return the balance control to the center position.

If your system does not appear to be working properly, refer to the Troubleshooting section on page 11.

Positioning your speaker system to get the best sound

Your Acoustimass 5 Series III speaker system may be used in a variety of ways. Here are some guidelines.

Cube considerations

A.In average-sizedlistening rooms, the best stereo effects result when the left and right cube arrays are spaced 6 to 12 feet apart (1.8 – 3.6 m). However, you can still achieve excellent results with separation as little as 3 feet (1 m) or as great as 15 feet (4.5 m).

B.The cube arrays are magnetically shielded for use with video systems and may be placed near your television without adversely affecting picture quality. However, the Acoustimass module is not shielded and should be kept at least 2 feet (.6 m) from a television.

C.Though there is no “correct” position for the cube arrays or the angle between them, the most lifelike effect will be achieved by providing a balance of direct and reflected sound. Experiment with the positions of the cubes for the results you prefer. Figure 6 shows some typical cube arrangements.

D.You may use the cube arrays with both cubes facing forward. This eliminates the benefits of direct and reflected sound, but may be appropriate for very small listening areas.
