Bose Lifestyle 20 Owner's guide - Page 8

Setting Up English ® Select the locations for your Lifestyle® 20 music system When you place your speakers according to the guidelines below, a combination of reflected and direct sound provides a good stereo image virtually everywhere in the room. You may experiment with the placement and orientation of the Jewel CubeTM speakers and Acoustimass® module to produce sound most pleasing to you. To adjust your system for the characteristics of your listening room, see "Fine-tuning your system" on page 18. Figure 2 Recommended speaker locations Jewel Cube speakers 1. For the most lifelike sound, place the Jewel Cube speakers 6-12 feet (1.8-3.6 m) apart. They can be as close as 3 feet (1 m) or as far apart as 15 feet (4.6 m). 2. Place the Jewel Cube speakers 6-12 inches (15-30 cm) from the surface behind them. 3. Direct one cube of each speaker toward the center of the room (Figure 2). Direct the other cube toward a side wall to create reflected sound. Note:The Jewel Cube speakers are magnetically shielded so you can place them close to a TV without affecting picture quality. Acoustimass module Follow these guidelines to select a location for the Acoustimass module. 1. Place the Acoustimass module along a side wall near the front of the room, if possible (Figure 2). You can place the module along the same wall as the speakers, if more convenient. 2. Aim the round opening (port) along the wall, 2 feet (.6 m) from a corner (Figure 2). Avoid blocking the port. 3. Select a convenient location - under a table, behind a sofa. Do not allow furniture or drapes to block the ventilation openings on the module. 4. Place the Acoustimass module within reach of the audio input cable, speaker cables, and an electric outlet. 5. For proper ventilation, place the Acoustimass module on its long side, with the connectors facing the floor (Figure 3). Or place it on its largest side, with the bass and treble controls facing up. Do not place the module on either end. 6. Once you have selected a position for the Acoustimass module, place the four selfadhesive rubber feet near the corners of the bottom surface. On a bare floor, the rubber feet provide increased stability and protection from scratches. 7. For best bass performance, do not place the module midway between any two walls. Note:To avoid interference with the TV picture, keep the Acoustimass module at least 18 inches (45 cm) from any TV. 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 rubber feet and center them in the matching shapes on the bottom of each speaker.

Place the music center on a level surface and allow enough room to lift the door. 2. Make sure it is close enough to any additional sound sources (TV, VCR, etc.) to allow for cable length. 3. Keep the music center within 30 feet (9.1 m) of the Acoustimass module (the length of the audio input cable). 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. 6 October 29, 2001 AM178934_09_V.pdf
