Setting Up

Before you begin
Thank you for purchasing the Bose Lifestyle 20 music system. This remarkably compact system is a result of advanced technology developed by years of research. Technological innovations that make the Lifestyle 20 music system possible include the smallest CD changer now available for home use and Jewel CubeTM speakers one-half the size of the previous Acoustimass cube speakers. To create speakers this small, the magnet inside is formed using the rare earth element neodymium and has ten times more energy (per unit volume) than conventional magnets. For high performance from such a small package, a port 3.8 inches (9.7 cm) long was designed in the shape of a nautilus shell and enclosed inside the tiny cube. These, and numerous other innovations, bring you the Lifestyle 20 music system, offering superb sound, elegance, technology, and simplicity for music and home entertainment. Your system includes: A Lifestyle music center with built-in AM/FM radio and six-disc CD changer Powered Acoustimass speakers consisting of two Jewel Cube speakers and a hide-away Acoustimass module An easy-to-use remote control Inputs for two video sound sources, an auxiliary source, and a tape deck Capability for operating two listening zones Your Lifestyle music system offers several ways to listen to superbly reproduced sound. You can use its built-in sound sources, connect additional equipment such as a tape deck, laserdisc player, VCR, or TV, and use two listening zones. Please take the time to follow this owners guide carefully. It will help you set up and operate your Lifestyle music system, and enjoy all of its advanced features. Save your owners guide for future reference.
CAUTION: Remove and dispose of the three manufacturers shipping screws from the bottom of the Lifestyle music center before setting up your system.
The shipping screws are for use by the manufacturer only. They are not re-installable.

Unpack 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 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 20 music system contains the parts identified in Figure 1.
Note: Find the serial numbers on the bottom panel of the Acoustimass module and the bottom of the music center. Write them on your warranty card and in the spaces provided on page 3.

Fine-tuning your system

In most situations, following the speaker placement guidelines (see page 6) for your Lifestyle 20 music system 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.

Figure 24

Bass and treble controls
Adjusting speaker controls
The Lifestyle 20 music system TREBLE and BASS controls are located on the Acoustimass module (Figure 24). 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.

This one-of-a kind converter allows a compatible learning IR remote to communicate with Bose Lifestyle systems The Model C-1024A makes it possible for multiple BOSE sound and video components to respond to the commands issued by a single Pronto or Harmony 880 learning remote control. Small enough to be easily hidden, the C1024 is designed for placement behind the video display in the home theater room. Only the small IR sensor remains visible near the front of the display where it receives the remote control commands. System control is achieved through a serial jack connection from the C-1024A to the rear panel of the LIFESTYLE system. The C-1024 is compatible with the Bose music center models LIFESTYLE 20, 25 and 30 and the MRI LIFESTYLE 40 and 50.
