Setting Up

Before you begin

Bose® Virtually Invisible® speaker technology allows you to enjoy lifelike home performances from the very latest surround sound encoded movies, CDs, and television shows, without a room full of speakers.

Your stereo VCR or stereo television sends the encoded program material to the surround sound receiver, which interprets it by distributing various sounds to particular speakers. Although the sound mix varies with different types of programs, dialogue is usually sent to the center speaker while sounds from the left or right side of the picture go to the left or right front speakers. Ambient sounds and special effects are directed to one or both of the surround (rear) speakers. The unique, easy-to-hideAcoustimass® module delivers bass for all channels. At any point in a surround sound performance, you may hear sound from all or just a few of the speakers, but the overall experience puts you in the center of the action.

To select surround-encodedprogram material, look for any of the terms Surround, Dolby Surround, and thedouble-Dsymbol* on tapes and discs, and the word “surround” preceding a TV broadcast. YourAcoustimass-10home theater speakers are also compatible with DolbyAC-3receivers and program material. The special settings for Dolby Surround andAC-3are described on page 11.

You can also enjoy a wide variety of stereo programming that is not surround-encodedwith yourAcoustimass-10speakers. Simply adjust your receiver accordingly.

Unpack the carton

Remove any staples from the opened carton flaps.

Remove the brown inner carton containing the five cube speaker arrays and the Acoustimass module terminal cover.

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.

Do not detach the removable cables connected to the Acoustimass module.

If the speakers or the Acoustimass module appear damaged, do not use them. Repack everything in the original carton and contact your authorized Bose dealer immediately.

Note: Now is a good time to record the serial number of these speakers on page 2 of this guide and on your warranty card. It is a good idea to save all packing materials for possible future use.

WARNING:

The Acoustimass module weighs 23 pounds (10.5 kg). Use good lifting practice to avoid injury.

To avoid danger of suffocation, keep the plastic bags that wrap these speakers out of the reach of children.

Setting Up

Placing your Acoustimass®-10speakers to achieve realistic home theater sound

The center speaker localizes action and dialogue on your screen. Sound from the center speaker should seem to come from within the picture.

The left and right front speakers create a sound image wider than the screen that seems natural to viewers sitting anywhere in the room.

The surround speakers add subtle sounds and special effects that expand the visual image, bringing the viewer into the center of the action. The surround speakers should be positioned to allow the sound to reach the viewer from both sides, rather than from directly behind.

You can place the front and center speakers near a TV screen with no picture interference, because all of the cube speakers are magnetically shielded.

The Acoustimass module is not magnetically shielded and should be at least 2 feet (.6 m) from your screen, but at the same end of the room as the front and center speakers. Bose® Acoustimass speaker technology takes advantage of the fact that the source of bass sound is difficult to locate, so you can hide the Acoustimass module conveniently out of sight.

A suggested home theater layout that conforms to the guidelines described above is shown in Figure 2. Twist the pairs of cube speakers so they describe angles that create room-fillingsound patterns.

You may choose to place the speakers differently, to take advantage of the sound characteristics of different rooms. Your speakers come with sufficient cable lengths to allow you to have the following distances between components:

Up to 20 feet (6 m) between the Acoustimass module and the receiver.

Up to 20 feet (6 m) between the Acoustimass module and the front and center cube speakers.

Up to 50 feet (15 m) between the Acoustimass module and the surround speakers.

Bose wall brackets and floor stands can extend your placement options. See “Accessories” on page 14.

NOTE:

Please follow wall bracket instructions carefully. Proper mounting will insure optimum performance from your system.

Setting Up

Select the locations for your speakers

The cables provided with your Acoustimass®-10system vary in length and provide a great deal of flexibility in speaker placement.

Left and right front cube speakers

Use the two cube speakers with black terminals. Figure 3 shows suggested ways to achieve an accurate left and right sound image.

Place the front speakers on either side of your TV, at least 6 feet (2 m), or as much as 15 feet (5 m) apart.

Place them in line with the center of the screen for the best sound balance (position 1). Or, place them in a lateral position, with one high and the other low (position 2). Placing them in a line above the top of the TV is a third choice (position 3).

The speaker on the left as you face the TV is connected to the LEFT FRONT jack on the Acoustimass module.

Center cube speaker

Select one speaker with a gray terminal for the front center speaker. Sound from the center speaker should seem to come from within the picture.

Figure 4 shows suggested positions for the center speaker.

Place the center cube speaker above, below, or on top of your television. If below, be sure that the cube speaker is not supporting the weight of the television in any way.

Keep it as close to the vertical center of the screen as possible, for the most accurate dialogue reproduction (positions 1 or 2).

Figure 3

Suggested choices for left and right front speaker placement

CAUTION: If you are placing the center speaker on top of the television, use the smaller of the two sets of four rubber feet provided. This will provide extra stability on surfaces such as marble or glass. Additional rubber feet are available, free, by calling the Bose® customer service numbers inside the back cover of this manual. Ask for Part Number178321-04.

Setting Up

Surround cube speakers

The remaining two speakers with gray terminals are to be used as surround speakers. The left and right rear channel sound should reach the viewer from both sides, rather than from directly behind. Refer to Figure 5.

Put one on the left and the other on the right, keeping them as far apart as possible, beside or just to the rear of the home theater seating area.

Place them high up, to avoid a direct sound path to the ears of the listeners (position 1).

If you want these speakers directly behind the seating area, make sure they are not directed at the viewers (positions 2 and 3).

The rear speaker on the left as you face the TV is connected to the LEFT SURROUND jack on the Acoustimass® module.

Acoustimass module

Bose® recommends putting your Acoustimass module at the same end of the room as the television monitor. To prevent interference, keep the module at least 2 feet (60 cm) from the television.

You may hide the Acoustimass module behind or under furniture, but do not block the opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.

If the opening faces the wall it increases the bass; if it faces away it decreases the bass. For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or corner.

Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the cable connection end, remove the cover by gently pulling it away.

After selecting a place for the Acoustimass module, attach the larger set of four rubber feet to the bottom surface for additional stability. The feet protect the cable connections and must be mounted when the Acoustimass module is standing on that end.

Setting Up

Connect the speakers

The supplied cables make it easy for you to connect your system. The connections at the Acoustimass® module are already made for you. There are three sets of cables, joined together to form ribbons, which may be separated or “unzipped” as much as needed to comfortably reach the speakers (Figure 7). Separate the cables as you are laying out the cable lengths.

The 20 foot (6 m) cable with three pairs of wires connects the Acoustimass module to thecenter, left, and right front cube speakers.

The 50 foot (15 m) cable with two pairs of wires connects the Acoustimass module to theleft and right surround cube speakers.

The 20 foot (6 m) cable with five pairs of wires connects the Acoustimass module to theoutputs on the receiver. Separate these wires just enough to reach the connectors.

Use the cable correctly

Each cable consists of insulated wire pairs attached to colored RCA connectors. The colors match the connector terminals on the cube speakers and are embossed with L, R, C, LS, and RS. The connectors have locating pins that assist you in making the correct connections (Figure 8).

The black connector marked L goes to the left front speaker.

The gray connector marked C goes to the center speaker.

The black connector marked R goes to the right front speaker.

The gray connector marked LS goes to the left surround speaker.

The gray connector marked RS goes to the right surround speaker.

Note: Do not attempt to splice cables. Do not use standard RCA cables to lengthen any of the supplied cables. Call Bose® customer service for cables specifically designed for this purpose (Part Number 187092). See the customer service numbers inside the back cover.

Figure 7

Separating cables

CAUTION:

Before making any connections turn off your receiver or amplifier and unplug it from the outlet (AC power mains). Not doing so may result in damage to your system.

Never connect the cubes directly to an receiver output. Always connect the cube speakers to the Acoustimass module, then connect the Acoustimass module to the receiver.

Never use broken or frayed wiring, which can result in electrical shock or damage to your system.

The supplied cables are not intended for in-wallinstallation. Check local building codes or enlist a qualified installer.

Setting Up

Check the connections

Check all connections from the receiver to the Acoustimass® module and the module to the cube speakers (Figure 9). Make sure all speakers are connected to the proper terminals according to their position in your room. Also make sure the two speakers with black terminal tabs are connected as front speakers.

At the receiver, check that the wires are connected in phase (+ to + and – to –).Incorrect wiring can result in a total loss of Acoustimass module output.

Be sure to correct any wiring problems before you plug your receiver in and turn it on.

CAUTION:

Do not allow exposed wires to brush against each other; this could damage your receiver.
