Before you begin

We appreciate your choice of the Bose Acoustimass 16 Series II or 15 Series III home ! entertainment speaker system. Each system features a combination of cube speaker arrays, center front speaker, and a powered Acoustimass module. Together, they reproduce the ! full-spectrum sound of multi-channel digital programming for a powerful and realistic home theater experience.

Unpacking the carton

Carefully unpack the carton contents as follows: 1. 2. Remove the brown inner carton containing the cube speaker arrays and center front speaker. Gently roll the large carton onto its side and pull out the Acoustimass module.
WARNING: To avoid injury, use care in lifting the module, which weighs 33 pounds (15 kg). Save all packing materials, which provide the best means to transport the system, for ! possible future use. If any parts appear damaged, do not use them. Instead, repack the system in the original ! carton and contact your authorized Bose dealer. Or, to contact Bose directly, refer to the address list included in the carton. Figure 1

Franais SETTING UP

Choosing locations for your speakers
Keep these guidelines in mind when choosing a location for each speaker: Select a stable and level surface for each of the small speakers. ! Vibration can cause them to move, particularly on smooth surfaces like marble, glass, or highly polished wood. To prevent this problem, rubber feet are provided for attachment to the bottom of the center front speaker. Note: You may order additional rubber feet, free of charge, by contacting Bose. Refer to the address list included in the carton. The center front speaker is for use at the front of the room and near the center of your TV. The cube speaker arrays in your system are identical and can be used interchangeably. The top and bottom cubes of each speaker array can be rotated to create ! room-filling sound patterns (b and d). All of the small speakers are magnetically shielded to prevent interference with a TV picture. The Acoustimass module should be at least 2 feet (.6 m) from your TV set to prevent ! interference. The shape and size of your room and location of the furniture in it will affect your choice of speaker locations. Use the examples below as the basis, but not the rule, for your home ! theater setup. Figure 2

Sample speaker placement (a and c) and performance results (b and d) Acoustimass 16 system a. b.
Acoustimass 15 system c. d.
Bose wall brackets and floor or table stands expand the options for placement of your speakers. For further information, see Accessories on page 14. Note: The Acoustimass 15 Series III system is designed for use with an optional center rear cube speaker array. For further details, see Optional upgrade for your Acoustimass 15 system on page 10.
Placing the center front speaker
Sound from the center front speaker should seem to come from within the picture to give the most realistic performance of on-screen action and dialogue. Place the center front speaker above, on top of, or below your television. Do NOT rest the weight of the television on the speaker. Keep it in line with the vertical center of the screen, if possible, for the most accurate ! reproduction of dialogue (as shown in Figure 2 on page 5). CAUTION: Before placing the center front speaker on top of a television, attach the four supplied rubber feet to the bottom of the speaker. Position two of the feet near the front edge and close together on the bottom surface. Place the other two feet in the rear corners on the bottom.
Placing your left and right front speakers
The goal for these speakers is to create a sound image that is wider than the screen and seems natural to viewers sitting anywhere in the room. Place the front cube speaker arrays on either side of your TV. Keep them from 6 feet (2 m) to 15 feet (5 m) apart (as shown in Figure 2 on page 5).
Placing your rear speakers
While the rear (surround) speakers may deliver some dialogue, they serve primarily to ! deliver discrete sounds and special effects that expand the visual image. They help bring the viewer into the center of the action. Choose locations that are practical and convenient, while considering these recommended guidelines: Position the left and right rear cube speaker arrays so they can deliver sound on both sides of the viewer, rather than from directly behind (as shown in Figure 2 on page 5). Place these speakers at the same height as the ears of a seated viewer or higher. Rotate the top and bottom cubes of each speaker to direct the sound to both the front ! and the back of listeners. If your system has a center rear speaker, position it halfway between the rear left and right speakers (as shown in Figure 2 on page 5).

Placing your Acoustimass module
Bose Acoustimass speaker technology makes it difficult to locate the source of ! low-frequency sound from this module. So feel free to hide it from view, and: Locate the module at the same end of the room as the television screen. Keep the module at least 2 feet (.6 m) from your TV set to prevent interference. To increase bass effects, turn the front opening toward a wall; turn it away from the wall to decrease bass effects. Keep both the front opening and the ventilation grille on the bottom of the module at least ! 2 inches (5 cm) from any other surface. Do not block the ventilation grille located on the bottom of the module. ! Impeding ventilation can cause a reduction in the bass-frequency output from the module. Figure 3

Checking and finalizing connections
Before plugging in the Acoustimass module, check all connections from the receiver to the the module and the module to the small speakers (Figure 5 on page 8 and Figure 8). Make sure all cube speaker arrays are connected to the proper terminals according to their position in your room. Check to be sure all wires are connected to your surround receiver with the proper polarity (+ to + and to wires). Incorrect wiring can result in a total loss of module output. Correct any wiring problems before you plug in your receiver and turn it on. When all the connections check out, plug the power cord from the Acoustimass module into an AC (mains) outlet. Plug in the receiver also. Note: Bose recommends using a quality surge suppressor on all electronics equipment. Voltage variations and spikes can damage electronic components in any system. Using a highquality suppressor (available at electronics stores) can eliminate the vast majority of failures caused by a power surge.
Optional upgrade for your Acoustimass 15 system
Your Acoustimass 15 Series III speaker system can be upgraded to provide you with 6.1- ! or 6-channel surround sound. The 6.1 upgrade kit contains one cube speaker array, a 50-foot (15.2 m) connecting cable, and complete connection instructions. To purchase the 6.1 upgrade kit in the same color as your current system, contact your local authorized Bose retailer. Or to contact Bose directly, see the address list included in the ! carton. When ordering, you will need to provide the serial number of your Acoustimass module. ! Refer to For your records on page 2 if you recorded the number there. If not, you can locate the number on the rear of the module near the connection panel.
Getting the most from your home theater speakers
With system connections completed and the module plugged in, your Acoustimass system is now ready for use. You may want to familiarize yourself with the controls and built-in protections that adjust ! the audio of this system (Figure 9). They offer options to suit your particular style of use and ! preferences. CAUTION: This system provides an automatic protection circuit to help guard against damage from electrical stresses and overload of the system. At high volume levels, the circuit activates to reduce output, which slightly decreases the volume. If you notice this decrease, be aware that your system is functioning as designed. This volume reduction also indicates that power input to the system may exceed safe levels. Sustained listening at these levels is not recommended. Figure 9

Audio adjustment knobs

Adjusting the bass/room compensation
After placing the Acoustimass module where you want it, you can fine-tune it for that ! location. Make this adjustment only as necessary. For example: If the system performance is thin or lacks bass, turn the BASS control (shown above) clockwise to increase the low-frequency output of the module. If the audio is boomy or overemphasizes bass, turn the knob counter-clockwise ! to reduce the low-frequency output of the module. The setting made at the factory is meant for use in the most common room arrangements.

Adjusting the LFE level

The LFE (low-frequency effects) level control (shown above) is for use only with receivers that provide an LFE/SUBWOOFER channel. By turning the knob, you can adjust the relative level of the low-frequency effects from movie soundtracks. Use it to match the volume level of the LFE channel with volume levels of your other speaker channels. You can check all levels by using the test tones feature on your digital surround sound receiver. For details on using this feature, refer to the owners guide provided with your ! surround receiver.

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. Each of the five cube speaker arrays, along with the Powered Acoustimass module, reproduces the full-spectrum of sound from multi-channel digital programming. Integrated Signal Processing assures full bass performance from all channels, at all listening levels, regardless of your receiver settings. Your stereo VCR, stereo television, or DVD player sends the encoded program material to the surround-sound receiver, which interprets and distributes the information to the Powered Acoustimass module. The module delivers the bass for all channels and sends appropriate sounds to each cube array. The sound mix varies with different program types: dialogue is usually sent to the center speaker, a visual soundstage is created by the left and right front speakers, and you feel in the center of the action because sounds and special effects are directed to the surround (rear) speakers. At any point in a surround-sound performance, you may hear sound from one, a few, or all of the speakers. To select surround-encoded program material, look for any of the terms Surround, Dolby Surround, the double-D symbol *, other digital formats, or the word surround preceding a TV broadcast. Your system is fully compatible with the latest home theater receivers. You can also enjoy a wide variety of stereo programming that is not surround-encoded with your Acoustimass 15 speakers.

Unpack the carton

Remove any staples from the opened carton flaps. Remove the brown inner carton containing the five cube speaker arrays. Gently roll the carton over onto its side and then onto its opening. Slowly lift the carton from around the Powered Acoustimass modules packing cushions. Do not detach the removable cables connected to the Powered Acoustimass module. If the speakers or the 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. Please save all packing materials for possible future use.

Placing your speakers to achieve realistic home theater sound
A suggested home theater layout that conforms to the guidelines described above is shown in Figure 2. You may want to place the speakers differently, to take advantage of the sound characteristics of different rooms.
Note: The cube arrays are identical and can be used for any channel. All of the cube arrays are magnetically shielded to prevent interference with a television picture. Twist the cube arrays so the speakers create room-filling sound patterns. Note: Bose wall brackets and floor stands can extend your placement options. See Accessories on page 13. Please follow wall bracket instructions carefully. Proper mounting will insure optimum performance from your system.

Figure 2

One suggested home theater layout

Center cube speaker

The center speaker localizes action and dialogue on your screen. Sound should seem to come from within the picture. Place the center cube array above, below, or on top of your television. If below, be sure that it is not supporting the weight of the television in any way. Keep the cube array as close to the vertical center of the screen as possible, for the most accurate dialogue reproduction.
CAUTION: If you are placing the center cube array 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 Number 178321-04.
Setting Up Left and right front cube speakers
The left and right front speakers create a sound image wider than the screen that seems natural to viewers sitting anywhere in the room. You can place them near a TV screen with no picture interference. See figure 2. Place the front cube arrays on either side of your TV, at least 6 feet (2 m), or as much as 15 feet (5 m) apart.

Surround cube speakers

The surround, or rear, speakers add discrete sounds and special effects that expand the visual image, bringing the viewer into the center of the action. The surround speakers may carry dialog as well. The surround speakers should be positioned to allow the sound to reach the viewer from both sides, rather than from directly behind. See Figure 2. Place the speakers at ear height or higher, if possible Adjust the rear surround speakers to direct the sound to the front and back of the listener.
Powered Acoustimass module
Bose Acoustimass speaker technology takes advantage of the fact that the source of pure bass sound is difficult to locate, so you can hide the Powered Acoustimass module conveniently out of sight. Place the module at the same end of the room as the television monitor. You may hide the 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. You may stand the Powered Acoustimass module vertically or horizontally (Figure 3). After selecting a place for the module, attach the larger set of four rubber feet to the bottom surface for additional stability.

CAUTION: To prevent interference, keep the module at least 2 feet (.6 m) from the television.

Connect the speakers

Connect the cube arrays to the Powered Acoustimass module, and then connect the module to your receiver. The supplied cables make this easy. The cables may be separated or unzipped as much as needed to comfortably reach the speakers. See Figure 4.

Figure 4

Separating cables
CAUTION: Before making any connections turn off your receiver and unplug it from the outlet (AC power mains). Not doing so may result in damage to your system. CAUTION: Never connect the cubes directly to a receiver output. Always connect the cube arrays to the Powered Acoustimass module, then connect the module to the receiver. 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-wall installation. Check local building codes or enlist a qualified installer.
Connect the Powered Acoustimass module to the center and front cube arrays
Three individual 20 (6m) foot wire pairs connect the Powered Acoustimass module to the Center, Right, and Left front cube arrays. Each cable connects to the module with a single plug. 1. Connect the wire pair marked C to the center speaker. Just press the terminal tab on the back of the cube array to insert the marked wire into the red terminal and the plain wire into the black terminal. See Figure 5. Release the tab to secure the wires. 2. Connect the wire pair marked R to the right front speaker (to the right of the TV as you face it). 3. Connect the wire pair marked L to the left front speaker.

Setting Up Connect the Powered Acoustimass module to the surround cube arrays
The 50 foot (15 m) cable with two pairs of wires connects the Powered Acoustimass module to the Right and Left surround cube arrays. Each has an individual plug on the module end. 1. The wire marked R connects the module to the right surround speaker (on your right as you face the TV). As shown in Figure 5, press the terminal tab on the back of cube array to insert the marked wire into the red terminal and the plain wire into the black terminal. 2. The wire marked L connects the module to the left surround speaker. 3. Insert the connectors firmly into their jacks at the Powered Acoustimass module.

Connect the Powered Acoustimass module to the receiver
The 20 foot (6m) cable with five pairs of wires and a single wire with an RCA plug connects the module to the outputs on the receiver as shown in the table below.
Note: The RCA plug comes with a cover installed. Remove this cover for connection to the LFE/SUBWOOFER OUT jack. If your receiver has no LFE/SUBWOOFER OUT jack, leave the plug cover in place; in this case this wire will not be used.
Match the polarity on the receiver. Connect the wire pairs in phase (+ to + and to ). a. Attach each marked wire (+) to the appropriate + terminal. b. Attach each plain wire () to the appropriate terminal. Connect the RCA plug to the receivers LFE/SUBWOOFER OUT jack. At the Powered Acoustimass module, be sure the receiver cable connector is firmly inserted.

CAUTION: Do not connect the Powered Acoustimass module directly to your television unless the television provides surround decoding circuitry and amplified outputs for all channels. CAUTION: Do not allow exposed wires to brush against each other; this could damage your receiver.

Check the connections

Check all connections from the receiver to the Powered Acoustimass module and from the module to the cube arrays (Figure 6). Make sure all cube arrays are connected to the proper terminals according to their position in your room. Check that all wires are connected in phase (+ to + and to ). Incorrect wiring can result in a total loss of module output. Correct wiring problems before you plug your receiver in and turn it on.

LFE level control

The LFE level control on your Powered Acoustimass module increases or decreases the relative level of low frequency effects on movie soundtracks. Use it to regulate the presence of these underlying deep bass sounds. You may find it unnecessary to adjust this control. The factory, or detent setting is appropriate for a majority of listening situations.

Bass control

The Bass control on your Powered Acoustimass module can help you customize your listening room. Turning the control to the right will add bass to the sound in rooms that might be characterized as too shrill. Turning down the control will brighten the listening room. As with the LFE level control, you may find the factory setting to be completely appropriate for your listening room.
Setting your Dolby Pro-Logic receiver
For video applications, we recommend the surround-sound center mode setting of your receiver as WIDE (Figure 8). Instructions for this process vary, depending on the brand and model of receiver you are using. Follow your receiver owners guide for testing and adjusting the balance of each speaker.

Figure 8

Setting your Dolby Digital receiver
Your Acoustimass 15 speakers are fully compatible with the output from Dolby Digital receivers. Integrated Signal Processing assures full bass reproduction for all channels regardless of receiver settings. However, the table below suggests a set of recommended receiver settings. The cube speakers are full-range, or LARGE speakers on the Digital screen menu. Turn the subwoofer and the LFE (low frequency effects) ON. Set the crossover to the lowest number possible, typically 80 Hz.

Note: The Acoustimass 15 speaker system incorporates an automatic protection circuit, which guards against most kinds of damage from electrical stress or overload. This circuit activates at high volume levels to reduce output, causing a slight decrease in volume. This is normal operation and indicates that power input may be exceeding safe levels. Sustained listening at these levels is not recommended.
Using Your Acoustimass 15 Speakers Be sure to get the Dolby Digital signal
To be sure that the Dolby Digital or other digital signal from your DVD player reaches your receiver, connect its digital sound output to the digital sound input on your receiver. You must use a coaxial cable, with RCA connectors on each end, or an optical (Toslink) cable that has unique, square cable ends. See Figure 9. Be sure to connect the digital sound jacks; these are in addition to the traditional analog connections that carry the Dolby Pro-Logic signal. Many DVD players have a switch on the back which you must place in the digital position. If you cannot find such a switch, there may be an on screen menu where you must select digital audio. You must also be sure to select Dolby Digital at your receivers front panel or remote control. For example, when playing a movie on a DVD, you must select a video output, in this case DVD, and an audio output, Dolby Digital. You may also have to set up the digital signal using the receivers front panel or on-screen menu. Please consult your receiver owners manual for specific details.
