Before you begin

Thank you for purchasing the Bose ^® Lifestyle ^® 50 system. Years of research lie behind this complete audio home entertainment system – the most advanced home theater system from Bose. Technological innovations that make the Lifestyle ^® 50 system unique include the Bose Personal ^™ music center, which places all system operations in the palm of your hand, and tiny Jewel Cube ^® speakers.

The interactive Personal music center is a clear departure from convention, communicating with the system through a two-way radio data link. The result for you is full control of this entertainment system as you move about your home.

The Bose Jewel Cube speakers are also far from conventional. Proprietary technologies ensure that these tiny speakers not only fill a room with sound, but also reproduce it more accurately than traditionally designed loudspeakers.

The other elements of the Lifestyle ^® 50 system are designed to be hidden from view:

• The elegant Lifestyle ^® CD changer, designed to give you flexibility in where it is placed
• The hideaway powered Acoustimass ^ module that delivers the rich, full, lifelike bass
• The Bose multi-room interface, with four independent audio outputs that allow you to enjoy Bose sound throughout your home.

Realism and impact

Your Lifestyle® 50 system is equipped with an all new Videostage® decoder that uses digital signal processing. The result is increased surround sound realism and impact both for movie soundtracks and music recordings. The Videostage decoder processes analog formats, as well as two or even single-channel PCM and Dolby Digital bitstreams, and helps to deliver the acoustic experience of the movies right in your home.

Compatibility

Your system is fully compatible with:

• Digital-audio bitstreams. Look for the symbol DOLBY or the terms Dolby Digital or PCM on DVD-Video disks. Your Lifestyle® 50 system cannot process MPEG-2 or DTS digital bitstreams.
• Surround-sound sources such as VCRs, stereo TVs, cable boxes and satellite receivers. Videostage decoding directs stereo information to the surround channels, so the sound of stereo broadcasts and rented or recorded tapes can approach that of your DVD disks.
• Surround-encoded analog or digital audio signals. Look for the terms Surround or Dolby Surround, or the symbol ☐[COLBY SURROUND] on tapes and discs, and the word “surround” preceding a TV broadcast.
• Stereo program material from TV, FM, CD and cassette. Videostage decoding delivers five channels, even when the original source contained only one or two.
• Monoaural program material. Videostage decoding can process a one-channel program into five-channel sound and direct the result to five independent speakers. Dialogue remains locked on-screen, while music and ambient effects fill the room.

Automatic sound level monitoring and control

Your enjoyment of movies is enhanced by Digital Dynamic Range® compression. This technology automatically monitors and adjusts the volume to let you to hear soft sounds, particularly dialogue, but prevents you from being overwhelmed by loud special effects. This is especially useful for late night viewing – it eliminates the need to constantly adjust the volume.

Unpacking the carton

Carefully unpack your system. Save all packing materials for possible future use. The original packing materials provide the safest way to transport your Lifestyle® 50 system. If any part of the product appears damaged, do not attempt to use the system. Notify Bose® or your authorized Bose dealer immediately.

Check to be sure your Lifestyle® 50 system contains the parts identified in Figure 1.

Note: Find the serial numbers on the bottom panels of the Personal™ music center, multi-room interface, CD changer, and Acoustimass® module. Then write them on your warranty card and in the spaces provided on page 3.
CAUTION: Be sure the three shipping screws on the bottom of the CD changer have been removed before setting up the system.
WARNING: The Acoustimass module weighs 33 pounds (15 kg). Use good lifting practice to avoid injury.
WARNING: To avoid danger of suffocation, keep the plastic bags out of the reach of children.

Selecting the locations for your Lifestyle® 50 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 Jewel Cube ^® speakers and Acoustimass ^® module to produce the sound most pleasing to you. For more discussion of speaker placement and room acoustics, see “Fine-tuning your system” on page 36.

Jewel Cube speakers

Follow these guidelines to select locations that provide the maximum home theater effect from your Lifestyle ^® 50 system (Figures 2 and 3).

CAUTION: Choose a stable and level surface for your Jewel Cube speakers. Vibration can cause the speakers to move, particularly on very smooth surfaces. For stability, peel off the backing from the two identical rubber feet and center them in the matching shapes on the bottom of each speaker.

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). The front speaker cables allow up to 20 feet (6.1 m) from the Acoustimass module.

1. Place the left and right front speakers so that they line up with the center of the TV screen.
2. Place them up to 3 feet (1 m) from the edge of the TV screen.

We recommend the 3-foot (1 m) maximum distance 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.

1. Direct one cube of each speaker forward. Direct the other cube toward the wall or in a different direction to create reflected sound. See the illustration of suggested reflected sound patterns in Figure 3.

Note: The Jewel Cube speakers are magnetically shielded so you can place them close to the TV without affecting picture quality.

Figure 2

Recommended front speaker locations

Figure 3
Speaker placement

Center speaker

The sound from the center speaker should appear to come directly from the center of the picture (Figure 2). The center speaker cable allows up to 20 feet (6.1 m) from the Acoustimass module.

Note: Do not place the speaker on its side, as this diminishes performance by blocking the Jewel Cube ports.

1. Place the center speaker directly above or below the center of the TV screen, or at the closest convenient location.
2. Align the speaker with the front of the TV screen (not pushed to the back of the TV).
3. Direct each cube speaker 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. The surround cables allow up to 50 feet (15.2 m) from the Acoustimass module.

1. Place the speakers at ear height or higher, if possible.
2. Adjust the rear surround speakers to direct the sound to the front and back of the listener (Figure 3).

Acoustimass® module

Follow these guidelines to select a location for the Acoustimass module.

Note: To avoid interference with the TV picture, place the Acoustimass module at least 18 inches (45 cm) from the TV.

1. Place the Acoustimass module along the same the wall or close to the same end of the room as the Jewel Cube ^® speakers (see the example along the front wall in Figure 3).
2. Select a convenient location – under a table, behind a sofa. Do not allow furniture or drapes to block the ventilation openings of the module.

3. Place the Acoustimass module within reach of the audio input cable, speaker cables, and an AC power (mains) outlet.

4. Select a position for the Acoustimass 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.

Figure 4
Acoustimass module positions

1. 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.
2. Aim the port (the round opening) into the room or along the wall to avoid blocking the port or creating too much bass.
3. 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.

Figure 5
The multi-room interface

Multi-room interface

Select a location for the multi-room interface. It may be placed out of sight if you like.

1. Place the multi-room interface within 30 feet (9.1 m) of the Acoustimass module (the length of the audio input cable).
2. Place the multi-room interface close enough to the sound sources (TV, VCR, DVD, 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® Customer Service.

CD changer

Select a convenient location for the CD changer.

1. Place the CD changer on a level surface. Allow enough room to lift the door.
2. Place the CD changer close enough to the multi-room interface to allow for cable length of 6 feet (2 m).

Connecting your home theater components to the Lifestyle® 50 system

There are many possible variations of equipment in a home theater system. In addition to the Lifestyle® 50 system, a home theater typically includes a stereo or mono TV and stereo VCR. In a digital home theater system, the primary source may be a DVD player. Your home theater might also include other types of equipment such as cable TV, laserdisc players, CDI players, additional VCRs, and a satellite decoder.

Note: A mono TV only serves as a display for the video, not as a source for the audio.

In order for the Lifestyle® 50 system to provide home theater effects, the program material must be 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 deliver stereo, all CD, DVD, and CDI players and nearly all laserdisc players do.

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 a digital sound source

Connect a DTV or DVD player's digital output directly to the female RCA jack on the audio input cable. Connect the DVD player's analog output to the AUX inputs of the multi-room interface. If your Lifestyle® system receives a valid digital signal, including PCM or Dolby Digital bitstreams, this digital sound is used. If no valid digital signal is received, your system selects the analog signal sent to the AUX inputs. The analog signal is processed by the Videostage® decoder to give you excellent home theater sound. If your digital audio source has an optical connector, you will need an adapter with an RCA (coaxial) connector. Consult your dealer or contact Bose®.

Note: Ensure the connection between the digital source and the Lifestyle® system is made using a 3 to 6 foot (1 to 2 m) standard audio cable or video cable. For longer lengths, use a 75 ohm cable.

Figure 11

Video sound source connec- tions to the multi-room interface

DTV or DVD analog outputs to AUX inputs Non-digital video sound source outputs to VIDEO inputs

Setting up a video sound source

The Lifestyle® 50 system has two sets of video sound inputs, VIDEO 1 and VIDEO 2, for your non-digital video sound sources, such as your TV or VCR (Figure 11).

Note: Your Lifestyle® 50 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 multi-room interface inputs. Cables may also be supplied with your components. If needed, audio cables are available at many electronics stores, or call Bose. Most audio cables are color coded. Match red connectors to right (R) jacks and black or white connectors to left (L) jacks.

How to set up your home theater

There are two basic methods for setting up your home theater. It is best to connect components directly to the Lifestyle ^® 50 multi-room interface, and select the sound source using the Personal ^™ music center. A second option is to use a stereo TV as the switching center to select the sound source. In each example, the analog outputs from the DVD player or other digital device are connected to the AUX inputs. You may need extra long audio cables or extensions for some of these connections.

Preferred method: Connect video sound sources directly to the Lifestyle® 50 system (Figure 12)

You may connect up to three video sound sources directly to your Lifestyle® 50 system. For example, connect the analog outputs of your DVD player to AUX, the VCR fixed outputs to VIDEO 1, and the TV to VIDEO 2 on the back of the multi-room interface. Connect the coaxial digital audio output from your DVD player to the female RCA coaxial connector on the audio input cable (connecting the multi-room interface with the module) using a male-to-male RCA audio cable.

If a valid digital signal is received by the Lifestyle® 50 system through the audio input cable, the system plays that audio source. If no valid digital signal is received, the system selects the analog audio signal sent to AUX.

When connecting your TV:

• Connect the TV fixed audio outputs to the VIDEO 2 inputs on the multi-room interface.
• 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 sound 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.

Alternate method: Connect video sound sources to your TV (Figure 13)

If your stereo TV has fixed audio outputs (audio outputs that do not change when you adjust the TV volume) 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 AUX inputs of the multi-room interface.
• 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 multi-room interface with the module) using a male-to-male RCA cable.
• Connect the TV fixed audio outputs to the VIDEO 1 inputs of the multi-room interface.
• 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 TV's 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.

About the video source

Your TV is the display for the video (picture) signal. Thus, the video signal must be connected directly to the TV. Do not connect it to the Lifestyle® 50 system.

Note: For assistance with video connections between your DVD player and/or VCR and TV, see your video components manuals.

Note: There is no video signal input (usually a yellow-coded jack) on the multi-room interface. The VIDEO INPUT jacks are for audio from a video source.

Connecting other external components

Use standard RCA audio cables to connect other components to your Lifestyle® system's multi-room interface, matching the red connector to R (right) and white (or black) connector to L (left).

You can use a Y-adapter (available at electronics stores) to connect a mono source.

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 interface RECORD OUT jacks. Connect the outputs (PLAY) from the tape deck to the interface TAPE IN jacks. See Figure 14.

Laserdisc player or additional CD changer

To use one of these components, connect its audio outputs to the multi-room interface VIDEO 1, VIDEO 2, or AUX (if not used for a digital source) input jacks, matching the red plug to R (right) and black or white plug to L (left). See Figure 14.

Turntable

To connect a turntable, you need a phono preamplifier (with RIAA equalization). You can order the appropriate model (PN 252603) from Bose® Customer Service (See the inside back cover for locations and phone numbers.). Connect the audio outputs of the phono preamplifier to the interface VIDEO 1, VIDEO 2, or AUX (if not used for a digital source) input jacks, matching the red plug to R (right) and black or white plug to L (left).

Note: The Lifestyle® 50 system cannot turn on or off a connected component.

Figure 14

Connecting external components

Connecting the antennas

The rear panel of your multi-room interface provides connections for the supplied AM and FM antennas (Figure 15). Untie and straighten the bundled wires on each antenna. Antennas provide better reception when their wires are fully extended.

Illustration of cable and ring components with a small component (no text or symbols)

FM antenna connections

1. Plug the FM antenna connector into the FM ANTENNA jack on the back of the interface.
2. Spread out the antenna arms. Experiment with both the placement and the angle of this antenna to provide optimum FM reception.

Note: A central antenna or cable, or an outdoor FM antenna, may be used with the antenna connections. To install an outdoor antenna, consult a qualified installer. Follow all safety instructions.

AM antenna connections

Note: To install the AM antenna on a wall, follow the instructions enclosed with the antenna.

1. Plug the AM antenna microplug into the AM ANTENNA jack on the interface.
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 away from the multi-room interface as possible, but at least 20 inches (50 cm) away, 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 75Ω EXTERNAL antenna connector on the back of the interface.

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.

Connecting power to your system

Plug the Acoustimass ^® module power cord into an AC power (mains) outlet. Then plug in the multi-room interface power pack.

Note: Your speakers will not operate unless you complete all cable and power connections before turning on the system.

CAUTION: Be sure the three shipping screws on the bottom of the CD changer have been removed before turning on the system.

Setting up the Personal™ music center

Set up the Personal music center after the rest of the system is connected and plugged in.

Note: When batteries are first installed in the music center, it sets up a radio-frequency link with the closest multi-room interface.

1. Hold the music center within a few feet of the multi-room interface.
2. Slide open the battery compartment on the back of the music center (Figure 17).
3. Insert 4 AAA or IEC-R03 1.5V batteries, or the equivalent, as shown. Match the + and - symbols on the batteries with the + and - markings inside the compartment.
4. Slide the battery compartment cover back into place.
5. Turn the music center over and touch the screen to wake it up if it appears blank. Press ON/OFF, FM, or any other source button to turn the system on.

If the music center continuously displays "NO RESPONSE," you need to try to establish its link with the multi-room interface again. Hold the music center close to the multi-room interface. Press and hold MUTE for about 5 seconds until you hear a beep and then release. After about 10 seconds, the music center should beep twice to confirm that the link is established.

Listening to the system

Your Lifestyle ^® 50 system uses digital signal processing to bring even greater realism and impact to both movies and music recordings. Built-in Dolby Digital decoding delivers up to 5.1 discrete audio channels (that is, five for the independent Jewel Cube ^® speakers and one for rich bass from the Acoustimass ^® module) from DVD, digital TV, next-generation cable boxes, and satellite receivers. With analog formats, as well as for two-channel PCM and Dolby Digital bitstreams, Videostage ^® decoding steers front information to the left, center, and right, and directs surround information to the left and right rear channels. As a result, the sound of stereo broadcasts and rented or recorded tapes can approach that of your DVD discs.

In addition, Videostage decoding can process a one-channel program and direct five-channel sound to five independent speakers. Dialogue remains locked on-screen, while music and ambient effects fill the room to increase your listening enjoyment.

You may choose to listen through two, three, or five speakers. Traditional stereo may be enjoyed through two or more speakers. Listening through three or five speakers helps anchor the dialogue of movies to the picture and provides a more solid image for music vocals. For the greatest surround effect, listening through five speakers gives you the most convincing sound experience.

Selecting the number of speakers

Initially, the AM and FM sources turn on in 2-speaker mode (front right and front left). All other sources initially turn on in 5-speaker mode. To change the speakers setting, press the MENU button until SPEAKERS is displayed (Figure 23). Use the or arrow buttons to change speaker mode from 5 to 3 or 2. Speaker settings are remembered for source and room.

Figure 23

The SPEAKERS selection display (Figure 23) also allows you to adjust the volume levels of the center and surround speakers. At the factory, these levels are set to zero. To adjust them, press the MENU button until SPEAKERS is displayed. Then use the or arrow buttons to adjust the levels.

• The CENTER level can be adjusted to soften or emphasize center speaker image.
• The SURROUND level can be adjusted to move the surround information forward in the room or further to the rear.

The system remembers the center and surround level settings for the room in which they were adjusted.

Using enhanced mode for movie soundtracks

Pressing VIDEO 1 or VIDEO 2 initially turns the system on in enhanced mode, with bass and treble settings specially designed for proper playback of movie soundtracks. Enhanced mode is turned on or off using the FILM BASS button on the display (Figure 24). When enhanced mode is on, the words FILM BASS appear on the display. Pressing TAPE initially turns the system on in the standard listening mode. FILM BASS cannot be engaged for AM, FM or CD.

Note: Enhanced mode provides more bass and less treble, as is specified for proper playback of movie soundtracks.

Figure 24

Selecting enhanced mode (FILM BASS) for movie soundtracks

Using simulated surround for mono movie material

Bose ^™ Videostage ^™ decoding can process a one-channel program into five-speaker sound, directing the signals so that dialogue remains locked on-screen, while music and ambient effects fill the room. You experience a surround sensation, providing extra enjoyment when you watch older, pre-stereo movies. This feature can be used for mono TV, FM, and AM programs. It is automatically turned on when a Dolby Digital bitstream indicates that it contains a mono program.

For other mono program sources, you can engage or disengage this feature using the Personal™ music center. Press MENU and hold it until drc or 1ch:5 appears on the display. If drc is displayed, press either of the top ◁ or ▷ arrow buttons to select 1ch:5 (Figure 25). Then use the lower ◁ or ▷ arrow buttons to select between On or -- (Off).

Receiving FM stereo or monaural broadcasts

When receiving sufficiently strong FM stereo broadcast signals, the radio automatically receives in the stereo mode; the STEREO indicator appears on the display. Weak stereo signals are received in the monoaural mode (the STEREO indicator is off).

To force the tuner to receive in stereo mode only, press and hold the center of the station display until you hear a high-pitched beep. To receive in monaural mode only, press and hold until you hear a low-pitched beep. However, even though you may have forced the stereo mode, monaural broadcast material is still heard in monaural. Retuning the station cancels any forcing.

Receiving AM stations

Normally, the AM radio receives sufficiently strong AM stations using a wide bandwidth filter. If you experience difficulty tuning to a weak AM station, you can force the AM tuner to use a narrow bandwidth filter to eliminate interference from other stations.

To force the tuner to use a narrow bandwidth filter, press and hold the center of the station display until you hear a low-pitched beep. To switch back to the wide bandwidth filter, press and hold until you hear a high-pitched beep. Retuning the station cancels any forcing.

Using the system with external components

Follow the instructions on pages 12-15 for connecting components.

Turn on your component directly or by using its remote control. Press VOLUME ▲ or ▼ on your Personal™ music center to raise or lower the volume. Control all other functions at the source, referring to its owner's manual if necessary. To begin, make sure the component is turned on and a tape, CD, DVD, laserdisc, etc. is loaded. If an external component sounds significantly louder or softer than other sources, see “Equalizing the volume levels of external sources” on page 37.

Note: The Lifestyle® 50 system cannot turn a connected component on or off.

Turning the system on and selecting the component

Press VIDEO 1, VIDEO 2, AUX, or TAPE on your Personal music center to select the desired component. This turns your system on and selects the component connected to that input. If the system is already on, this button selects the component.

The appropriate display indicator appears when the system is on and the component is selected.

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.

Using a tape recorder with your system

If you are listening to any source except TAPE, the output signal of that source is directed to the RECORD OUT jacks.

Note: The ROOM outputs of the Lifestyle® 50 system are designated by the letters A through D. In a multi-room system, the source that is playing in the room designated by the letter closest to the beginning of the alphabet is sent to the RECORD OUT jacks.

You may also specify a source to be directed to the RECORD OUT jacks even if you are not listening to that source. To do this:

1. Select RECORD OUT with the MENU button. The words RECORD OUT are displayed under the source display area (Figure 38).
2. Select a source to record. The selected source appears in the source display area in place of the dashes (Figure 38). If you want to remove your RECORD OUT selection, press CLEAR. The dashes reappear.

The selected source stays on until you turn RECORD OUT off. If the CD changer is selected for RECORD OUT, it shuts off after 24 hours if you have not turned it off sooner.

1. When you are ready, set the tape deck to record.

Fine-tuning your system

Figure 39
Treble and bass controls

Line drawing of a server unit with ventilation ducts and ports (no text or symbols)

In most situations, you only need to follow the speaker placement guidelines (see "Setting Up" on pages 6-8) for your system to provide excellent sound quality. You do not need to adjust tone settings for changes in volume, since Bose® patented integrated signal processing provides a natural tonal balance over the full range of volume settings.

If desired, you can further fine-tune your system as described here.

Adjusting speaker controls

The Lifestyle ^ 50 system treble and bass controls are located on the Acoustimass ^ module (Figure 39). 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 o'clock 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 careful use of the treble and bass controls.

Too much or too little treble

Rooms that reflect a lot of sound, 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 sound muffled or dull. Moving speakers further 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 also affects the amount of bass you hear. Placing the module closer to the corner of the room increases bass. Moving the module away from the corner decreases bass.

Optimizing AM/FM radio reception

You can adjust the orientation of your AM/FM antenna for the strongest signal by selecting SIGNAL LEVELS with the MENU button (Figure 40). Select the AM or FM radio, and the display shows you the strength level of the received signal. While watching the display, reposition your antenna until the highest possible signal level is achieved. The signal level can vary from 0 to 99. The manual tuning keys are provided so that you can check the signal strengths of multiple stations.

Figure 40
AM/FM antenna signal strength display

Equalizing the volume levels of external sources

The SIGNAL LEVELS selection in the MENU options allows you to adjust and equalize the volume gain levels received from externally connected sources (VIDEO 1, VIDEO 2, AUX, TAPE). For example, you can adjust the gain level of an external source so that volume level 50 on this source sounds as loud as level 50 from a built-in source.

1. Using the MENU button, select SIGNAL LEVELS.
2. Press VIDEO 1, VIDEO 2, TAPE or AUX and you are shown a gain adjustment display (Figure 41). After listening to the built-in sources (FM, AM, CD) at your preferred volume level, use the arrow keys to adjust the signal level settings (GAIN) of the connected sources until you get the same volumes. The adjustment range is from -15 to +15.

Operating in more than one room

Your Lifestyle ^® 50 system can control up to four sets of Bose ^® powered speakers, allowing your family to enjoy different audio sources (CD, radio, TV, etc.) in up to four rooms. These rooms are referred to as room A, B, C, and D, with room A being the primary room (the one used for a one-room system). If two or more rooms are connected to your system, the Personal ^™ music center displays ROOM and HOUSE buttons, and room indicators (A, B, C, and/or D). Figure 48 shows an example display for a two-room system.

Figure 48

Example display for a two-room system

The ROOM button lets you control a single room or two or more rooms that share a source

Understanding the room indicators

A boxed letter indicates the presently-selected room or rooms. The selected room is affected by any source changes, or any change you make using the VOLUME, MUTE, ON/OFF, or SLEEP buttons.
B An unboxed letter indicates a room listening to a shared source. A shared source is one that is playing in the controlled room as well as in up to three additional rooms. If you change the radio station, CD track, etc., of the shared source, the change affects all rooms sharing this source. However, you cannot change sources for all affected rooms at the same time. The VOLUME, MUTE, ON/OFF, and SLEEP buttons only affect the boxed room(s).
☐ An empty box appears for each connected room when you press the HOUSE button. When you change the volume in the HOUSE mode, the numerical level appearing on the display does not represent the actual volume level in all connected rooms. It only represents the actual volume in rooms represented by a boxed letter.

Using the ROOM button

The ROOM button allows you to select any connected room and control any sound source you want to hear in that room. Each time you press the ROOM button you can transfer control from one room to the next in A-B-C-D order. The room indicators on the display tell you what is currently selected. Rooms listening to a shared source can be linked and controlled as one room.

Turning on different sources in more than one room

Let's say you have a two-room system (rooms A and B) and the entire system is off. To turn on a different source in each room:

1. Wake up the Personal™ music center.
2. Press the ROOM button until the room indicator A is displayed. Press a source button, such as VIDEO 1, to turn on the system and listen to your DVD player in room A. Adjust the volume to the desired level.
3. Press the ROOM button again. The room indicator B is displayed. Press a different source button, such as CD, to listen to a CD in room B. Again, adjust the volume to the desired level.
4. Press the ROOM button again and notice that the room indicator ☑ displayed. You are controlling room A once again and the displays indicates that the VIDEO 1 source is on.

Setting up a shared source

Now, let's say the system is already on and you want to play the FM radio in rooms A and B:

1. Wake up the Personal music center.
2. Press the ROOM button until the room indicator is displayed. Press the FM source button and adjust the volume to the desired level for room A.
3. Press the ROOM button again to select room ☐Press the FM source button and adjust the volume to the desired level for room B. Now, the indicators A ☐ are displayed.
4. Press the ROOM button again. The indicators A B appear on the display indicating that you can control these two rooms together. Any button command given now (SOURCE, VOLUME, MUTE, ON/OFF, SLEEP) is applied to both rooms.

Note: Remember that there are limits to using different sources in different rooms. With one tuner, the system cannot play one radio station in one room and another radio station in another. Similarly, with one CD changer, the system cannot play two different CDs at the same time.

Linking rooms for common control

There are two ways to link rooms in order to control them as one.

• Set up a shared source in two or more rooms and select them together using the ROOM button. See “Setting up a shared source” above.
• Link all connected rooms using the HOUSE button. See “Using the HOUSE button” on page 43.

Returning to single-room control

After you have gained control of multiple rooms using the ROOM button, you can use the ROOM button again to gain control of a single room. Press ROOM until the room you want is displayed (A, B or C). Control that room as desired.

Using the HOUSE button

Using the HOUSE button, you can link all rooms together and control them as one. When you press the HOUSE button, an empty box indicator is displayed for each connected room. Any button pressed after that (any source button, VOLUME, MUTE, or SLEEP) affects every room. When you are done listening you can press OFF to turn off the entire system.

Note: If you do not press any additional buttons after pressing HOUSE, pressing HOUSE again cancels HOUSE mode.

Press the HOUSE button before each command to apply that command to all rooms:

Press ... To do this ...

HOUSE then a source Play the selected source in all connected rooms.

HOUSE then VOLUME ▲▼ Adjust the volume up or down by the same amount in all rooms that are on, or all connected rooms if they are all off. The system remembers the differences among the original room volume settings.

HOUSE then MUTE Silence all connected rooms that are on, even if any were previously muted individually. To cancel this command, press HOUSE then MUTE again. Any rooms that were muted before this command was given stay silent until individually unmuted. If you unmute an individual room after it was muted by a HOUSE - MUTE command, the other rooms remain silent until each one is unmuted individually. Pressing HOUSE then VOLUME ▲ unmutes all muted rooms.

HOUSE then SLEEP Set the SLEEP timer for all rooms that are on. The SLEEP time selected applies to all rooms that are on even if they are playing different sources. If the SLEEP timer was already set in one or more rooms, the display shows the longest time already set. You can accept this time or change it for all the rooms. To cancel the HOUSE - SLEEP command, press HOUSE, SLEEP, CLEAR, and then DONE.

HOUSE then OFF Turn off the entire system.

Note: Instead of setting the whole house to one sleep time, you can set different sleep times for individual rooms by using the ROOM button to select each room and setting SLEEP.

When two or more rooms are linked, adjusting the SLEEP time affects all linked rooms (indicated by boxed letters).

Using more than one Personal™ music center

If you have a multi-room system, you can add additional music centers for some or all of the connected rooms. Each multi-room interface can be controlled by a maximum of four music centers. Each music center can control up to four rooms.

To add a new music center to your system, follow the setup instructions on page 17. Be sure to install the batteries and turn it on for the first time close to the multi-room interface to allow the new music center to set up a radio frequency link with your system. If the multi-room interface is not plugged in or the music center is out of range, the display indicates NO RESPONSE.

Finding a misplaced Personal™ music center

The “find me” feature assists you in locating the music center. Press the LOCATE MUSIC CENTER button on the back of the multi-room interface (under the antenna connections, next to the CD changer cable connection). The volume drops in any rooms that are on and any music center within range of the multi-room interface eventually begins beeping and flashing. The beeping and flashing continues for two minutes. Touching the screen of any music center stops it from beeping and flashing. Pressing VOLUME ▲ on any music center cancels the LOCATE MUSIC CENTER function.
