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 video sound source (stereo VCR, laserdisc or digital video player, 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-6home theater speakers are also compatible with Dolby Digital(AC-3)receivers and program material. The special settings for Dolby Digital are described on page 14.

You can also enjoy a wide variety of stereo programming that is not surround-encodedwith yourAcoustimass-6speakers. Simply adjust your receiver as described on page 14.

*Dolby and the double-Dsymbol are trademarks of Dolby Laboratories Licensing Corporation.

Setting Up

Unpack the carton

Remove any staples from the opened carton flaps.

Lift out the two brown inner cartons.

Remove the five cube speakers from their packaging.

Remove the Acoustimass® module end cover from its packaging.

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 19 pounds (8.6 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®-6speakers 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 (60 cm) 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.

Placing it near a corner increases bass output from the module.

A suggested home theater layout that conforms to the guidelines described above is shown in Figure 2.

You may choose to place the speakers differently, to take advantage of the sound characteristics of different rooms. For instance, where walls are absent or the room is large, you may prefer not to angle the left and right speakers as shown. You can experiment to find the best position.

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.

Setting Up

Select the locations for your speakers

The lengths of cable supplied with your Acoustimass®-6system provide a great deal of flexibility in speaker placement. Optional Bose® extension cable,add-onconnectors, wall brackets, and floor stands can add to your choices. See “Accessories” on page 17.

Left and right front cube speakers

Use the two cube speakers with black terminals that are marked L/R (Figure 3). There are several ways to achieve an accurate left and right sound image (Figure 4).

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). Placing them in a line above the top of the TV is another choice (position 2).

Aim the speakers inward for more accurate imaging or outward for a more spacious effect. Adjust them according to your preference.

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

Setting Up

Center cube speaker

Select one speaker with a gray terminal marked C/S as the front center speaker (Figure 5). Sound from the center speaker should seem to come from within the picture.

Figure 6 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.

Aim this speaker straight ahead for onscreen imaging.

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

Note: To obtain additional rubber feet, free, call Bose® Customer Service (listed on the inside back cover), and ask for Part Number178321-04.

Surround cube speakers

The remaining two speakers with gray terminals marked C/S are the surround speakers. Their left and right rear channel sound should reach the viewer from both sides, rather than from directly behind (Figure 7).

Put one on the left and the other on the right, beside or just to the rear of the home theater seating area.

Position them so they do not create a direct sound path to the ears of the listeners (position 1).

Generally aim them away from the viewers, toward the rear or side walls (positions 2 or 3).

If you want these speakers directly behind the seating area, make sure they are not directed at the viewers.

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

Suggested choices for center speaker placement

CAUTION: Before placing the center speaker on top of a television, attach the four small rubber feet to its bottom surface. They give added stability on slippery surfaces, such as polished furniture, marble, or glass.

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.

Placing the module close to a corner increases the bass output. Moving it toward the center of the wall reduces the output.

If the opening faces the wall, it further 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 module vertically or horizontally (Figure 8). Attach the large set of rubber feet to the bottom surface. If you plan to stand the module on the cable connection end, do not use the module end cover, but be sure to attach the large rubber feet to protect the connections.

Setting Up

Connect the speakers

Note: You can refer to Figure 12 on page 12 for an overview of the completed connections.

The supplied cables make it easy for you to connect your system. Each cable connector is colored gray or black and embossed with a letter to identify the cube speaker, the output, or the input it matches. 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 needed to comfortably reach the speakers (Figure 9). Separate the cables as you are laying out the cable lengths. However, you may want to keep the unextended length of cable joined, making it easier to hide.

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

Note: If you have already installed cable behind walls or under floors, or believe you need to splice the supplied cables for any other reason, inquire about theadd-onconnectors and extension cable available from Bose® Customer Service. Refer to page 17 for details on these accessories. Bose Customer Service telephone numbers are listed on the inside back cover.

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.

Figure 9

Separating cables

CAUTION:

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.
