5. Once you have selected a position for the module, place the four self-adhesive rubber feet near the corners of the bottom surface. The rubber feet provide increased stability and protection from scratches. 6. Aim the port (the round opening) into the room or along the wall to avoid blocking the port or creating too much bass. 7. For best bass performance, do not place the port at equal distances from any two walls or from a wall and the ceiling.
CAUTION: Do not cover the ventilation openings of the Acoustimass module. The slots on the end provide ventilation for the built-in electronic circuitry, and should not be blocked. CAUTION: The magnetic field from the Acoustimass module is not an immediate risk to your video tapes, audio tapes, and other magnetic media. However, you should not store tapes directly on or near the Acoustimass module.

Music center

Select a location for the music center. 1. Allow enough room to open the CD player cover. 2. Place the music center close enough to the sound sources (TV, VCR, DVD player etc.) to allow for cable length. If you need additional audio and/or video cables to connect all of your components, see your dealer or call Bose. 3. Place the music center within 30 feet (9.1 m) of the Acoustimass module (the length of the audio input cable).
Connecting the speakers and Lifestyle music center
Once you have selected locations for your music system, connect the speakers. CAUTION: Make sure all components are unplugged from the power outlet before you begin hooking up the system.
Connecting the cube speaker arrays to the Acoustimass module
Each speaker cable contains two wires. The wire marked with a red collar is positive (+) and the plain one is negative (). These wires match the positive (red) and negative (black) terminals on the back of each speaker. To lengthen the cable, use heavy-duty RCA extension cables or splice in 18-gauge or thicker cord (connecting + to + and to ). To purchase cables, see your dealer or electronics store, or call Bose customer service.

If a valid digital signal is received by the Lifestyle 25 system through the audio input cable, the system plays that audio source. If no valid digital signal is received, it selects the backup analog signal being sent to AUX. When connecting your TV: Connect the TV fixed audio outputs to the VIDEO 2 inputs on the music center. Turn the TV speakers off or the volume all the way down. (If there is an internal/external speakers switch, select external speakers. Do not connect any speakers to the TV.) Turn off any special TV settings such as expanded stereo, mega-bass, phantom, or SAP. They prevent proper surround processing through your Lifestyle system. Set the TV balance control to the center of the dial or range. Set tone controls to flat or the middle position (neutral). Set TV to the stereo position.

To the module
(2) To direct video sound sources through your TV This is an alternative connection method. (See Figure 11.) If your stereo TV has fixed audio outputs (the audio signal level doesnt change) and it allows you to select the source of the signal (VCR, laserdisc, cable, etc.), then you can:
Connect your DVD player L and R outputs to the music center AUX inputs. Connect the DVD video output to one of the video inputs on the TV. Connect the coaxial digital audio output from your DVD player to the female RCA connection on the audio input cable (connecting the music center with the module) using a male-to-male RCA cable. Connect your home theater components to the TV inputs. Connect the TV fixed audio outputs to the VIDEO 1 inputs on the music center. Turn the TV speakers off or the volume all the way down. (If there is an internal/external speakers switch, select external speakers. Do not connect any speakers to the TV.) Turn off any special TV settings such as expanded stereo, mega-bass, phantom or SAP. They prevent proper surround processing through your Lifestyle system. Set the TV balance control to the center of the dial or range. Set tone controls to flat or the middle position (neutral). Set TV to the stereo position.
Note: If necessary, as a second choice, you can use the variable audio outputs from your stereo TV. Turn off or disconnect the TVs speakers and leave the volume control up close to the maximum setting. Note: If you connect your stereo VCR through your stereo TV, do not use coaxial cable. Instead, connect the VCR L and R audio outputs to the TV L and R audio inputs to ensure proper stereo and surround sound.

Figure 14

The AM loop antenna
1. Plug the AM antenna connector into the AM ANTENNA jack on the back of the Lifestyle music center. 2. Stand the loop antenna on the base, following the instructions enclosed with the antenna. 3. Move the loop part of the antenna as far as possible but at least 20 inches (50 cm) from the music center and at least 4 feet (1.2 m) from the Acoustimass module. Experiment with the orientation of the loop for optimum AM reception.
Connecting to a cable radio signal
To connect your system to the FM signal available from some cable TV companies, contact your cable provider for assistance. The connection is made to the FM 75 EXTERNAL antenna connector on the back of the system.
CAUTION: Be certain that the installation includes a signal splitter so that only the FM band, not the cable TV band, is transmitted to the system. It is necessary to use a splitter that filters the signal to prevent any re-emissions of the TV spectrum through the system.
Installing the batteries in the remote control
1. Slide open the battery compartment on the back of the remote (Figure 15). 2. Insert 3 AA or IEC-R6 1.5V batteries, or the equivalent, as shown. Match the + and symbols on the batteries with the + and markings inside the compartment. 3. Slide the battery compartment cover back into place. Replace the batteries when the remote control stops operating or its range seems reduced. Alkaline batteries are recommended.
Note: Do not change the settings of the factory-preset miniature switches. See Changing the house code settings on page 32 for information on how to prevent conflicts with other Lifestyle music systems.

Select the locations for your Lifestyle 25 system
When you place your speakers according to the guidelines below, a combination of reflected and direct sound provides the audio atmosphere of a home theater. You may experiment with the placement and orientation of the cubes to produce the sound most pleasing to you. For the best surround effect, adjust the speakers so you cannot identify the exact sound source. It is preferable not to aim the cubes directly at the listener. For more discussion of speaker placement and room acoustics, see Fine-tuning your system on page 22.

Speaker locations

CAUTION: Choose a stable and level surface for your speakers. Vibration can cause the speakers to move, particularly on smooth surfaces like marble, glass, or highly polished wood. For additional stability, you can add rubber feet to your speakers. You may obtain rubber feet (part no. 178321), free of charge, from Bose. Contact Bose Customer Service (see listings on the inside back cover).
Follow these guidelines to select locations that provide the maximum home theater effect from your Lifestyle 25 system (Figures 2 and 3).
Left and right front speakers The sound from the left and right front speakers should seem to appear at the edge of the picture, so that the acoustic image is close to the size of the visual image (Figure 2). 1. Place them on line with the horizontal center of the TV screen. 2. Place each speaker up to 3 feet (1 m) from the edge of the TV screen. We recommend a maximum distance of 3 feet (1 m) so that the sound does not become too separated from the picture. You may wish to vary this distance based on room conditions and personal preference. The front cables allow the cube speakers to be placed up to 20 feet (6.1 m) from the Acoustimass module. 3. Direct one cube of each array forward. Direct the other cube toward the wall or in a different direction to create reflected sound. (See the illustration of reflected sound patterns in Figure 3.)
Note: The cube speakers are magnetically shielded so you can place them close to the TV without affecting picture quality.
Center speaker The sound from the center speaker should appear to come directly from the center of the picture (Figure 2). The center cable allows the center speaker to be placed up to 20 feet (6.1 m) from the Acoustimass module. 1. Place the speaker on line with the vertical center of the screen, above or below (whichever is closer to the screen), or the closest convenient location. 2. Place the speaker in line with the front of the screen (not pushed to the back of the TV). 3. Direct each of the cubes slightly away from center, to create a wider area of direct sound (Figure 3).

Note: If you put the speakers in a bookcase unit, be sure to place each one at the front edge of the shelf. Placing speakers in an enclosed space can change the tonal quality of the sound. This effect is minimized if the shelves are filled with books.

Surround speakers The surround (rear) speakers create an area of sound around the listener. Place them in the back half of your room. Direct the cubes so that you do not pinpoint the exact location of the sound source (Figure 3). The surround cables allow the speakers to be placed up to 50 feet (15.2 m) from the Acoustimass module.

Acoustimass module positions
Follow these guidelines to select a location for the Acoustimass module. CAUTION: To avoid interference with the TV picture, place the module at least 18 inches (45 cm) from the TV. 1. Place the module along the same wall as the TV, or close to the same end of the room as the front speakers (see the example along the front wall in Figure 3). 2. Select a position for the module (Figure 4). For proper ventilation, place it on the long edge, with the connectors facing the floor. An alternate position is on its largest side, with the bass and treble controls facing up. Do not place the module on either end, as shown by the last two views in Figure 4.

Note: Once you have selected a position for the module, place the four self-adhesive rubber feet near the corners of the bottom surface. The rubber feet provide increased stability and protection from scratches.
3. Select a convenient location under a table, behind a sofa. Do not allow furniture or drapes to block the ventilation openings of the module. 4. Place it within reach of the audio input cable, speaker cables, and an electric outlet. 5. Aim the port (the round opening) into the room or along the wall to avoid blocking the port or creating too much bass.

Connecting the Acoustimass module to the music center
CAUTION: Make sure no strands of wire from any terminal touch any other terminal. Bridged wires create short circuits that affect proper operation of your system.
Connect the module to the music center with the audio input cable (Figure 6). 1. Plug the small black multi-pin connector (flat side facing up) into the jack marked SPEAKER ZONE 1 on the back of the music center. 2. Insert the right-angle multi-pin connector on the other end of the audio input cable into the AUDIO INPUT jack on the module. Align the connector at the angle shown in Figure 6.
Note: Be sure that each connector is inserted completely into each jack.
3. Extend the audio input cable as much as possible, since it includes an antenna for the remote control. For information on connecting zone 2, see Using two listening zones on pages 23-24.

Connecting your home theater components to the Lifestyle system
There are many variations of equipment in a home theater. A basic home theater system might include a stereo or mono TV and stereo VCR with the Lifestyle 25 system. Your home theater can include many other combinations of equipment, including cable TV box, laserdisc players, CDI players, additional VCRs, and satellite decoders.
Note: A mono TV only serves as a display for the video, not as a source for the audio.
In order for the Lifestyle system to provide home theater effects, the program material must be recorded in stereo or surround-encoded, and the device playing the material must be stereo. Look for the word surround on the tape, CD, or preceding the TV broadcast. To hear stereo or surround sound from encoded video tapes, you must have a stereo (HiFi) VCR. While not all VCRs are stereo devices, all CD and CDI players and nearly all laserdisc players play in stereo format.
Note: Line level outputs from most VCRs or laserdisc players are fixed. If your VCR, laserdisc player, or other video sound source has fixed and variable outputs, use the fixed outputs.
Setting up the primary video sound source
The Lifestyle music center has two sets of video sound inputs for the primary sources (Figure 10). If you set up your music center a distance from your TV, you may need extra long audio cables or extensions.

Figure 9

Connecting components through your TV Cable TV

Laserdisc

Note: Your Lifestyle 25 system includes one 6-foot (1.8 m) stereo cable to connect the right (R) and left (L) audio outputs from a component to the music center inputs. Cables may also be supplied with your components. If needed, cables are available at many electronics stores, or call Bose customer service. Most audio cables are color coded. Match red connectors to right (R) jacks and black or white connectors to left (L) jacks.
There are three basic methods for setting up your home theater. It is easiest to use a stereo TV as the switching center to select the sound source. The next easiest option is to use a stereo VCR as the switching center. The third option is to connect components directly to the Lifestyle music center, and select the source from the Lifestyle remote or control panel.
(1) To direct your video sound sources through your TV If your stereo TV has fixed audio outputs (the audio signal level does not change), and it allows you to select the source of the signal (VCR, laserdisc, cable, etc.):

Connect your home theater components (VCR, cable box, laserdisc player, etc.) to the appropriate TV inputs. See Figure 9. Connect the TV fixed audio outputs to the VIDEO 1 or 2 inputs of the music center. Turn the TV speakers off or the volume all the way down. (If there is an internal/external speakers switch, select external speakers. Do not connect any speakers to the TV.) Set the TV balance control to the center of the dial or range. Set tone controls to flat or the middle position (neutral). Set the TV to the stereo position.
Note: If you connect the audio outputs from your TV to the music center, be sure to use the audio (L and R) and video outputs from the VCR to the TV. If the audio signal passes through two coaxial cable connections (like the connection from a cable TV box), in some cases the stereo or surround encoding may be lost. Note: If necessary, as a second choice, you can use variable audio outputs from your stereo TV. Turn off or disconnect the TVs speakers and leave the volume control up close to the maximum setting.

Setting Up Figure 10

Music center connectors

Figure 11

Connecting components through your VCR Cable TV
(2) To direct your video sound sources through your VCR If your TV is not a stereo model, or does not have the appropriate outputs, connect your stereo VCR to the music center. Use the VCR as a tuner to select other connected sound sources. See Figure 11.
Connect your home theater components to the appropriate VCR inputs. Connect the VCR video out signal to the TV through VIDEO IN or composite video input. You can also use the RF (coaxial or 75) or antenna input. Turn the TV speakers off or the volume all the way down. (If there is an internal/external speakers switch, select external speakers. Do not connect any speakers to the TV.) Connect the VCR fixed audio outputs to the VIDEO 1 or 2 inputs of the music center. Note: To ensure proper stereo or surround sound, connect the L and R audio outputs from your stereo VCR directly to your music center L and R VIDEO 1 or 2 inputs, as shown in Figure 11. If you prefer to connect the audio outputs from your TV to the music center, be sure to use the audio (L and R) and video outputs from the VCR to the TV. If the audio signal passes through two coaxial cable connections (like the connection from a cable TV box), in some cases the stereo or surround encoding may be lost.

Cable TV Laserdisc

(3) To connect components directly to the Lifestyle music center If you cannot (or do not choose to) use your TV or VCR to select the sound sources, connect up to three sound sources directly to the Lifestyle music center. For example, connect a VCR into VIDEO 1, a laserdisc to VIDEO 2, and a TVs fixed audio outputs to AUX on the music center. See Figure 12. By pressing VIDEO 1, VIDEO 2, or AUX on the remote control or SOURCE SELECT on the music center control panel, you choose which sound source to hear.

Note: Selecting VIDEO 1 or 2 on your Lifestyle system automatically selects SURROUND (5-speaker) mode, and selecting AUX or TAPE automatically selects STEREO (2-speaker) mode. If you wish, you can change the speaker mode after you select the source.
Audio out Video out to TV

About the video source

Your TV is the display for the video (picture) signal. Therefore, the video signal must be connected directly to the TV. The video signal should not be connected to the Lifestyle music center.
Note: For assistance with video connections, see your video components manuals. Note: There is no video signal input (usually a yellow-coded jack) on the music center. The music center VIDEO INPUT jacks are for audio from a video source.

Other connections

Use standard RCA audio cables to connect other components to your Lifestyle system, matching the red connector to R (right), white (or black) connector to L (left). You can use a Y-adapter (available at electronics stores) to connect a mono source. However, the left and right speakers then play the same monaural sound.

Tape deck

To use an external tape recorder (analog audio cassette, analog open reel, digital audio tape, or Digital Compact Cassette), connect the inputs (REC) of the tape deck to the music center TAPE OUT jacks. Connect the outputs (PLAY) from the tape deck to the music center TAPE IN jacks. See Figure 13.
Additional CD player or changer
To use an external CD player or changer, connect the outputs from the component to the music center AUX INPUT jacks. See Figure 13.

Turntable

To connect a turntable, you need a phono preamplifier (with RIAA equalization). Consult your dealer for the appropriate model.
Note: The Lifestyle 25 system cannot turn a connected component on or off.

Fine-tuning your system

Figure 29

Bass and treble controls

In most situations, following the speaker placement guidelines (see pages 6-7) provides excellent sound quality. You do not need to adjust tone settings for changes in volume, since Bose patented signal processing technology provides a natural tonal balance over the full range of volume settings. If desired, you can further fine-tune your system as described below.
Adjusting speaker controls
The Lifestyle 25 system TREBLE and BASS controls are located on the Acoustimass module (Figure 29). They allow you to adjust the treble (high frequencies) and bass (low frequencies). In the normal setting, the dots on each control are in the 12 oclock position. You can also locate the normal setting by feeling when the control settles into the notch at this position. Turn the controls clockwise to increase, and counterclockwise to decrease, the amount of treble or bass.
Compensating for room acoustics
The acoustics (sound qualities) of your room can affect the overall sound quality of any speaker system. In general, you can reduce many problems with acoustics by the cautious use of the TREBLE and BASS controls.
Too much or too little treble Rooms with too few sound-absorbing furnishings, especially those with bare floors and walls, may sound overly shrill or bright. Turning down the treble control (toward ) decreases treble sound.
Rooms with a lot of sound-absorbing furnishings, such as upholstered furniture, wall-to-wall carpet, or heavy drapes, may reduce the treble sound of your system. Moving speakers farther away from soft furnishings increases treble. You can increase treble sound by slightly turning up the treble control (toward +).
Too much or too little bass You can decrease bass sound by turning down the bass control (toward ). To increase bass, turn up the bass control (toward +).
Acoustimass module placement affects the amount of bass you hear. Placing the module closer to the corner of the room will increase bass. Moving the module away from the corner will decrease bass.
Using two listening zones

Figure 30

Example of two listening zones: the Lifestyle 25 speakers in zone 1 and Acoustimass powered speaker system in zone 2

The Lifestyle 25 system can direct sound from one or two sound sources to two different listening areas at the same time. Each listening area, whether a room or a group of rooms (including outdoor areas), is referred to as a zone. By adding powered speakers and a second remote, you can establish two listening zones.

How zones work

Zones 1 and 2 can play different sound sources at the same time CD, AM/FM tuner, TAPE, VIDEO sound, or AUX. Both zones can listen to the same sound source at the same time. Only one radio station can be played at a time.

Living room Zone 1

Setting up two zones
Bedroom Zone 2 The Lifestyle 25 speakers are set up in zone 1. Any combination of rooms and floors in your home can be set up as zones. Use an appropriate Lifestyle system cable to connect a second Bose powered speaker system to the SPEAKER ZONE 2 jack on the back of the music center. You can also use special adapters to connect an existing stereo system. Use a second Lifestyle system remote control to operate zone 2. See your dealer or contact Bose for information on obtaining additional powered speakers, remote controls, cables, and adapters for connecting additional equipment.
Setting a second remote for zone 2
You need a second remote control, set to ZONE 2, to operate speakers connected to the ZONE 2 output. To set your second remote to control speakers in the second zone, follow these steps: 1. Open the remote control battery cover. 2. Locate miniature switch 8 (Figure 31). If it is set down for ZONE 1, slide it up for ZONE 2, using a paper clip, ballpoint pen, or similar object. 3. Make sure the house code switches (1, 2, 3, and 4) match those on your first remote. (See page 25 for more information on house codes.) 4. Replace the battery cover.

Operating Your Lifestyle 25 System Operating two listening zones
Controlling the zones from the remote controls To control two zones you need to have remotes set to each zone. See instructions on page 23 for setting a second remote to zone 2. You can select and control sources in each zone by commands from its remote control. You can control the volume in each zone directly from its remote control. You can turn each zone on and off directly from its remote control. You can listen to the same source in both zones. Controlling the zones from the music center control panel Turning two zones on and off from the music center involves a sequence of actions.
To turn zone 2 on from the music center, press and hold the ON/OFF key. Watch the display to see which zone is on or off. Release the key to keep the option shown. Holding the ON/OFF key causes this repeating sequence: zone 1 zone 2 First ON OFF Second ON ON Third OFF ON To turn the zones on or off from the music center when both zones are on, press the ON/OFF key for the following sequence: zone 1 zone 2 ON ON First press OFF ON Second press OFF OFF Third press ON OFF Fourth press OFF OFF Additional presses zone 1 repeats ON and OFF When zone 1 is on (even if zone 2 is also on), the music center keys control zone 1 only. When zone 2 is the only zone on, the music center keys control zone 2. If you press SOURCE SELECT for FM or AM while zone 2 is playing the other radio band, the band selected in zone 2 flashes on the display. If you do not want to change the band playing in zone 2, use SOURCE SELECT to choose another source within two seconds.
