Franais SETTING UP

Placing your speakers to achieve realistic home theater sound
Keep these guidelines in mind when choosing a location for each speaker: The Acoustimass module should be at least 2 feet (.6 m) from your TV set to prevent interference. All of the small speakers are magnetically shielded to prevent interference with a TV picture. 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. In an Acoustimass 10 system, the center front speaker is for use at the front of the room and near the center of your TV. The other cube array speakers are identical and can be placed interchangeably around the room (Figure 2a and 2b). The top and bottom cube on each cube array speaker can be rotated to create room-filling sound patterns. In the Acoustimass 6 system, all five single cube speakers are identical and can be placed interchangeably around the room (Figure 2c and 2d). 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 10 Series IV system a. b.
Acoustimass 6 Series III system c. d.
Front left and right speakers
The goal for these is to create a sound image wider than the screen that seems natural to viewers sitting anywhere in the room. Place these two front speakers 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).

Center speaker

Sound from the center speaker should seem to come from within the picture to give the most realistic performance of on-screen action and dialogue. Place the center speaker above, on top of, or below your TV. Do NOT rest the weight of the TV on the speaker. Keep the speaker 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 speaker on top of your 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 at the rear outer edges on the bottom.

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 speakers 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. For the Acoustimass 10 system, rotate the top and bottom sections of the rear cube speaker arrays to direct the sound to the front and back of the listener (see Figure 3 on page 7). For the Acoustimass 6 system, aim the rear cube speakers slightly behind the listener or reflect the sound off the rear wall (see Figure 2 on page 5).
Powered Acoustimass module
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 TV 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 grilles located on the bottom of the module.! Impeding ventilation can cause a reduction in the bass-frequency output from the module. Figure 3

Connecting the Acoustimass module to the receiver
The system input cable is 20 feet (6.1 m) long and connects to your surround receiver. Unlike the speaker cables, this input cable has a multi-pin connector that inserts into the Audio Input jack on the module (Figure 6). Figure 6
System input cable connection Module input jack
System input cable connector
At the other end of the system input cable, multiple wire pairs unzip for easy reach and insertion into terminals on your receiver. A red collar marks a wire as positive (+) wire. CAUTION: Do NOT connect your module to the TV, which lacks the required amplification. The single RCA connector at that end is for use ONLY with a receiver that handles ! low-frequency effects and provides an LFE/SUBWOOFER jack (Figure 7). Figure 7
Unzipping the paired wires RCA connector for LFE only Wire pair
CAUTION: Before making these connections, turn off your receiver to prevent unwanted noises when you plug the Acoustimass module into it. To make the connections (Figure 8 on page 10): 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 secure the connection. Connect each wire pair on the other end of the system input cable to your surround receiver, which should have audio output terminals labeled: Right, Left, and Center for the front audio channels. Right Surround and Left Surround for the rear channels. ! The specific labels on your receiver may differ slightly. CAUTION: Do not allow exposed wires to brush against each other; this could damage your receiver. 3. Carefully match the polarity of the connections (+ to + and to ). Attach each red-collared wire (+) to the appropriate + terminal. Attach each plain wire () to the appropriate terminal. 4. If applicable to your receiver, insert the RCA plug marked LFE on the system input cable into the LFE/SUBWOOFER OUT jack on your surround receiver. Remove the cover first.

Checking the 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 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.
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 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.
Franais USING YOUR SYSTEM
Setting your digital surround sound receiver
Speakers in your Acoustimass 6 Series III or Acoustimass 10 Series IV system are fully ! compatible with the audio output of digital surround receivers. The systems integrated signal processing supports full low-frequency reproduction from all channels. To gain complete advantage of these system capabilities, you may want to adjust some! settings on your receiver. To make changes, use the digital display menu on the receiver and refer to the list of recommended settings, below. Speaker Left and right Center Left and right surround LFE/Subwoofer Receiver setting LARGE LARGE LARGE ON
Note: If your receiver provides it, the LFE or Subwoofer option setting should be ON and the crossover value at the lowest number possible, which is typically 80 Hz.
Receiving a digital audio signal
For the digital audio signal from your DVD player to reach your surround receiver, you need a digital audio connection between the DVD player and receiver (Figure 10). 1. 2. Use either the Optical or Coaxial input (not both) on the receiver to connect to the digital output from the DVD. Be sure to select the digital output in the setup menu of your DVD player.

Connecting the Acoustimass module to the receiver
The system input cable is 20 feet (6.1 m) long and connects to your surround receiver. Unlike the speaker cables, this input cable has a multi-pin connector that inserts into the Audio Input jack on the module (Figure 6). Figure 6

At the other end of the system input cable, multiple wire pairs unzip for easy reach and insertion into terminals on your receiver. A red collar marks a wire as positive (+) wire. CAUTION: Do NOT connect your module to the TV, which lacks the required amplification. The single RCA connector at that end is for use ONLY with a receiver that handles ! low-frequency effects and provides an LFE/SUBWOOFER jack (Figure 7). Figure 7
Unzipping the paired wires RCA connector for LFE only Wire pair
CAUTION: Before making these connections, turn off your receiver to prevent unwanted noises when you plug the Acoustimass module into it. To make the connections (Figure 8 on page 10): 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 secure the connection. Connect each wire pair on the other end of the system input cable to your surround receiver, which should have audio output terminals labeled: Right, Left, and Center for the front audio channels. Right Surround and Left Surround for the rear channels. ! The specific labels on your receiver may differ slightly. CAUTION: Do not allow exposed wires to brush against each other; this could damage your receiver. 3. Carefully match the polarity of the connections (+ to + and to ). Attach each red-collared wire (+) to the appropriate + terminal. Attach each plain wire () to the appropriate terminal. 4. If applicable to your receiver, insert the RCA plug marked LFE on the system input cable into the LFE/SUBWOOFER OUT jack on your surround receiver. Remove the cover first.

Checking the 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 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.

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 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.
Franais USING YOUR SYSTEM
Setting your digital surround sound receiver
Speakers in your Acoustimass 6 Series III or Acoustimass 10 Series IV system are fully ! compatible with the audio output of digital surround receivers. The systems integrated signal processing supports full low-frequency reproduction from all channels. To gain complete advantage of these system capabilities, you may want to adjust some! settings on your receiver. To make changes, use the digital display menu on the receiver and refer to the list of recommended settings, below. Speaker Left and right Center Left and right surround LFE/Subwoofer Receiver setting LARGE LARGE LARGE ON
Note: If your receiver provides it, the LFE or Subwoofer option setting should be ON and the crossover value at the lowest number possible, which is typically 80 Hz.

Receiving a digital audio signal
For the digital audio signal from your DVD player to reach your surround receiver, you need a digital audio connection between the DVD player and receiver (Figure 10). 1. 2. Use either the Optical or Coaxial input (not both) on the receiver to connect to the digital output from the DVD. Be sure to select the digital output in the setup menu of your DVD player.
For additional setup and operating information, please refer to the owners guide that came with your surround receiver. Figure 10
Digital signal receiver connections Use one or the other, NOT both
Setting your analog surround sound receiver
For analog (non-digital) surround sound applications, we recommend that you set the ! surround sound center mode of your receiver to Wide. For instructions on how to change this setting, refer to the owners guide provided with your surround receiver.

Troubleshooting

If you have a problem with your Acoustimass speaker system, turn off your sound source and try the following solutions. If you still have a problem, contact your Bose dealer to arrange for service. To contact Bose directly, refer to the address list included in the carton. Problem System does not function at all No sound What to do Make sure the receiver and powered Acoustimass module are plugged into an operating AC outlet and that the receiver is turned on. Be sure to select an audio source on the receiver (video, CD, DVD, tuner). Increase the volume. Disconnect any headphones. Check the speaker connections. Make sure that both the powered Acoustimass module and the receiver are plugged in. For digital sound, be sure a coaxial or optical cable connects the digital output of the DVD player with the digital input on your receiver. Be sure the audio source selected is correct. For example, select DVD audio on your receiver to hear the DVD sound.

No surround sound

Make sure the source material contains surround sound. If you are using the Dolby Pro-Logic mode on your receiver, make sure surround sound is turned on. Be sure the source material (DVD, laser disc, or broadcast programming) is Dolby Digital encoded. Be sure your receiver is processing a signal from a Hi-Fi VCR, stereo TV, laserdisc, or DVD player, or other surround sound source. If you are using digital programming, verify that the settings are correct at the receiver. Be sure the speaker connections from the receiver to the amplifier are in the correct phase, red-collared wire to red jack (+ to + and to ). Move your Acoustimass module closer to a wall or corner to increase bass. Move it farther from a wall or corner to decrease bass. Adjust the LFE level or Room Compensation control. Make sure speaker wire is not damaged. Reduce the volume of external components connected to the receiver.
