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

Changing the HDMI video resolution
Your Lifestyle system transmits video at the highest possible resolution to your HDTV. Occasionally, you may want to change to a lower resolution, even though your HDTV can display a higher resolution. For example, if a source signal is converted by your Lifestyle system to a much higher resolution, the result may not be pleasing to your eye. In that case, you could change to a lower resolution. The video resolution can only be set when the Lifestyle system is connected to an HDTV through the HDMI OUT connector. Also, the video resolution cannot be set lower than that of the video signal entering your Lifestyle system (no down-conversion). Finally, setting the video resolution (that your Lifestyle system transmits to the TV) for CBL-SAT, DVD, VCR, or AUX changes the resolution for all other sources. The video resolution you set for the HDMI output applies across all the sources.
To change to a lower resolution, do the following: 1. On the Lifestyle remote, press the Settings button and see if (Video Resolution) is in the list
of menu options. If it is, go to Step 2. Otherwise, the ability to access this option has been disabled in the System menu, and you must complete Steps A through D (below) to enable it. A. On your remote, press System to display the system menu on the HDTV. B. Move right to (Video), then press ENTER.
