Digital Dynamic Range
This feature automatically monitors and adjusts the volume to let you hear soft sounds
(particularly dialogue), but reduces the chance of you being overwhelmed by a loud special
effect such as an explosion. Digital Dynamic Range compression is initially disengaged for all
sound sources.
You can engage or disengage Digital Dynamic Range compression using the Personal music
center. Press MENU and hold it for about two seconds. You should see drc on the display. If
not, press the left or right arrow button until drc is displayed. Using the left or right arrow
button below drc, select On or – – (Off) (Figure 26). The music center remembers your
settings in the event of a power loss.
Turning on the digital audio source
Turn on the DVD player, DTV, or other digital audio source. Make sure a disc is loaded in the
DVD player.
Turning on the system and choosing digital sound
Press AUX to turn your system on to play digital sound. If your Lifestyle

connected to the AUX jacks on the multi-room interface.
Selecting listening material
To select material with compatible digital-audio bitstreams, look for the terms PCM or Dolby
1
Digital, or the symbol
MPEG-2 or DTS digital bitstreams. Make sure a connection is made between your DVD
player or Digital TV's digital audio output and your system's digital audio input.
To select surround-encoded analog or digital audio material, look for the terms Surround or
Dolby Surround, the symbol 3 on tapes and discs, or the word "surround" preced-
ing a TV broadcast. You can listen to any program material in five-speaker (surround sound)
mode, though you may not hear sound from all five speakers all the time. Some monaural and
stereo materials will not cause sound to be directed to the surround speakers. Even with
surround-encoded material there are times when no sounds are directed to the surround
speakers.
