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.

Adjusting center and surround levels
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.
