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
We appreciate your choice of the Bose Acoustimass 15 series II or Acoustimass 16 home entertainment speaker system. 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. The cube speaker arrays, along with the powered Acoustimass module, reproduce 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 speaker array. The sound mix varies with different program types: dialogue is usually sent to the center cube speaker array, a visual soundstage is created by the left and right front cube speaker arrays, and you feel as if you are in the center of the action because sounds and special effects are directed to the rear cube speaker arrays. At any point in a surround-sound performance, you may hear sound from one, a few, or all of the cube speaker arrays. To select surround-encoded program material, look for the terms Surround, Dolby Surround, the double-D symbol 3, Dolby Digital 1, other digital formats, or the word surround preceding a TV broadcast. Your system is compatible with home theater receivers. You can also enjoy a wide variety of stereo programming that is not surround-encoded.

Unpacking the carton

WARNING: The powered Acoustimass module weighs 33 pounds (15 kg). Use good lifting practice to avoid injury. WARNING: To avoid danger of suffocation, keep the plastic bags that wrap these speakers out of the reach of children. Note: This product is not to be powered by any DC-to-AC inverters that may be found in automobiles, recreational vehicles, boats, ships, or other similar situations. Carefully unpack the carton contents (Figure 1): 1. 2. 3. 4. Remove the brown inner carton containing the cube speaker arrays. Gently roll the carton over onto its side. Slowly pull the Acoustimass module from the carton. Stand the module up.

If the cube speaker arrays or the module appear damaged, do not use them. Repack everything in the original carton and contact your authorized Bose dealer immediately. Or, to contact Bose directly, see the list of offices and phone numbers enclosed with your system. 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.

Front center cube speaker array
The front center cube speaker array localizes action and dialogue on your screen. Sound should seem to come from within the picture. Place the front center cube speaker 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 front cube speaker array as close to the vertical center of the screen as possible, for the most accurate dialogue reproduction. CAUTION: Choose a stable and level surface for your cube speaker arrays. Vibration can cause them to move, particularly on smooth surfaces like marble, glass, or highly polished wood. If you are placing the center cube speaker array on top of your television, use the set of four rubber feet provided. You may obtain additional rubber feet (part number 178321-04), free of charge, by contacting Bose Customer Service. See the list of phone numbers included with your system.
Front left and right cube speaker arrays
The front left and right cube speaker arrays create a sound image wider than the screen that seems natural to viewers sitting anywhere in the room. You can place the cube speaker arrays near a TV screen with no picture interference. Place the front cube speaker arrays on either side of your TV, at least 6 feet (2m), or as much as 15 feet (5m) apart (see Figure 2).

Rear cube speaker arrays

The rear, or surround cube speaker arrays add discrete sounds and special effects that expand the visual image, bringing the viewer into the center of the action. The rear cube speaker arrays may carry dialogue as well. Position the left and right rear cube speaker arrays to allow the sound to reach the viewer from both sides, rather than from directly behind (see Figure 2). Place the rear cube speaker arrays at ear height (when seated) or higher, if possible. Rotate the top and bottom sections of the rear cube speaker arrays to direct the sound to the front and back of the listener. If you have a center rear cube speaker array (Acoustimass 16 system or upgraded Acoustimass 15 Series II system), place it so that it is centered between the rear left and right cube speaker arrays (see Figure 2).
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 furniture, but do not block the opening. Be sure there is at least 2 inches (5 cm) between any surface and the front opening or the grille on the bottom. If the opening faces the wall it increases the bass; if it faces away it decreases the bass. CAUTION: To prevent interference, keep the module at least 2feet(.6m) from your TV set. Figure 4

Powered Acoustimass module placement
Note: Placing the module horizontally, or on its side, may reduce ventilation, inhibiting its ability to play at full output for extended periods of time.
Setting Up Connecting the speakers
CAUTION: Never connect the cube speaker arrays directly to a receiver output. Always connect them 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.
Connecting front cube speaker arrays to the Acoustimass module
Three individual 20-foot (6.1m) speaker cables connect the center, right, and left front cube speaker arrays to the Acoustimass module (Figure 5). Be sure to match the correct cable with the corresponding speaker location. Front speaker cables have blue RCA connectors at one end with L (left), R (right), or C (center) molded into the connectors. The other ends of the cables have two wires. The red collars on the + wire are labeled LEFT, RIGHT, or CENTER. Note: The center rear cube speaker array is included with the Acoustimass 16 system or may be added to an Acoustimass 15 Series II system.

Connecting rear cube speaker arrays to the Acoustimass module
Each rear cube speaker array is connected to the Acoustimass module with a 50-foot (15m) speaker cable (Figure 5). Be sure to match the correct cable with the corresponding speaker location. Rear speaker cables have orange RCA connectors at one end with LR (left rear), RR (right rear), or CR (center rear) molded into the connectors. The other ends of the cables have two wires. The red collars on the + wires are labeled LEFT REAR, RIGHT REAR, or CENTER REAR. 1. Connect the wire pair marked RIGHT REAR to the right rear cube speaker array (on your right as you face the TV). Press the terminal tab on the back of the cube speaker array. Insert the marked wire into the red terminal and the plain wire into the black terminal. Release the tab to secure the wires. Connect the wire pair marked LEFT REAR to the left rear cube speaker array. If you have a center rear cube speaker array (Acoustimass 16 system or upgraded Acoustimass 15 Series II system), connect the wire pair marked CENTER REAR to the center rear cube speaker array.
Note: The Acoustimass 15 Series II system may be upgraded by adding a center rear cube speaker array. See Upgrading your Acoustimass 15 Series II speaker system on page 12. 4. Plug the other end of each cable into the RIGHT REAR, LEFT REAR, and CENTER REAR orange RCA jacks, respectively, on the Acoustimass module.
Connecting the Acoustimass module to the receiver
The 20-foot (6.1m) system input cable connects the module to your surround receiver (see Figure 6). The system input cable has a multi-pin connector on one end and several wire pairs on the other. The wire pairs of the cable may be separated or unzipped as much as needed to comfortably reach the surround receiver connections. Each wire pair is marked on the cable jacket with RIGHT, LEFT, CENTER, RIGHT SURROUND, LEFT SURROUND, or CENTER SURROUND to indicate where each wire connects to the receiver. CAUTION: Before making any connections turn off your receiver and unplug it from the AC (mains) outlet. Not doing so may result in damage to your system. CAUTION: Do not connect the powered Acoustimass module directly to your TV unless it provides surround decoding circuitry and amplified outputs for all channels. 1. 2. Insert the multi-pin connector on the system input cable into the input jack on the Acoustimass module. Tighten the two thumbscrews to assure a secure connection. Connect each wire pair on the other end of the system input cable to your surround receiver. Carefully match the polarity of the connections (+ to + and to ). Attach each marked wire (+) to the appropriate + terminal. Attach each plain wire () to the appropriate terminal. Note: The RCA plug of the system input cable 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. 3. If applicable, connect the RCA plug marked LFE on the system input cable to the LFE/SUBWOOFER OUT jack on your surround receiver.

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

Setting Up Checking the connections
Check all connections from the receiver to the Acoustimass module and from the module to the cube speaker arrays (Figure 5 and Figure 6). Make sure all cube speaker arrays are connected to the proper terminals according to their position in your room. Check that all wires are connected to your surround receiver 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.
Connecting the Acoustimass module to power
Note: Bose recommends using a quality surge suppressor on all electronics equipment. Voltage variations and spikes can damage electronic components in any system. A quality suppressor can eliminate the vast majority of failures attributed to surges and may be purchased at an electronics store. After you have checked all system connections, plug the power cord of the powered Acoustimass module into an AC (mains) receptacle. Your Acoustimass speaker system will turn on and off automatically as it receives a signal from your surround receiver.
Upgrading your Acoustimass 15 Series II speaker system
Your Acoustimass 15 Series II speaker system can be upgraded to provide you with 6.1 or 6 channel surround sound. The 6.1 upgrade kit contains one black (PC 029661) or white (PC 029662) cube speaker array, a 50-foot connecting cable, and complete connection instructions. To purchase the 6.1 upgrade kit, contact your local authorized Bose retailer or call Bose directly. See the list of Bose offices and phone numbers enclosed with your system. When ordering, you will need to know the serial number of your Acoustimass module.

Using your system For realistic home theater sound
CAUTION: The Acoustimass 15 Series II and Acoustimass 16 speaker systems incorporate 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.

Adjusting the LFE level

The LFE (low-frequency effects) level control on your powered Acoustimass module increases or decreases the relative level of low-frequency effects on movie sound tracks. Use it to regulate the presence of these underlying deep bass sounds. Use the test tones feature in your digital surround sound receiver to match the volume levels for each of the cube speakers. Then use the LFE control on the Acoustimass module to match the volume of the LFE channel to the cube speaker channels.
Adjusting the bass/room compensation level
This feature will allow you to fine-tune your system after you have placed the Acoustimass module in your selected location. If the room sounds thin or lacks bass, turn the BASS control in a clockwise direction to increase the bass level of the module. If the room sounds boomy or has too much bass, turn the knob in a counter-clockwise rotation to reduce the bass level of the module. The factory or detent setting is appropriate for a majority of listening situations.
Setting your digital surround sound receiver
Your Acoustimass 16 or Acoustimass 15 Series II speakers are fully compatible with the output from digital surround receivers. Integrated Signal Processing assures full bass reproduction for all channels regardless of receiver settings. However, the following table suggests a set of recommended receiver settings. The cube speaker arrays should be set to LARGE in the receivers digital display menu. The LFE, or subwoofer, is set to ON. If applicable, the crossover value should be set to the lowest number possible, typically 80 Hz.
