Operating Your Lifestyle ® 25 System
Listening to your Lifestyle ® 25 system
Your Lifestyle ® 25 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 (i.e., five for the independent cube speaker arrays 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 directs stereo information to the surround channels,
so the sound of stereo broadcasts and rented or recorded tapes can approach that of your
DVD discs.
In addition, Videostage decoding processes a one-channel program and directs 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.
Your Lifestyle ® 25 system offers the option of listening in 5, 3, or 2-speaker mode. The system
turns on in SURROUND (5-speaker) mode. For most video material (mono, stereo, or sur-
round), listening in 5 or 3-speaker mode helps anchor the dialogue to the picture while
providing a fuller sound.
Using enhanced mode for movie soundtracks
Pressing VIDEO 1, VIDEO 2, or AUX turns the system on in enhanced mode, with bass and
treble settings specially designed for proper playback of movie soundtracks. Press the same
button (VIDEO 1, VIDEO 2, or AUX) again to alternate between enhanced mode for movies
and standard mode for other listening. Pressing TAPE turns the system on in standard mode.
Press TAPE again to alternate between enhanced mode for movies and standard mode for
other listening.
Note: Enhanced mode provides more bass and less treble, as is specified for proper
playback of movie sound.
Digital Dynamic Range ® compression
Digital Dynamic Range ® compression automatically adjusts the volume to allow you to hear
soft sounds (particularly dialogue) and to prevent you from being overwhelmed by a loud
special effect (e.g., an explosion). This feature is engaged when you turn on the system, but
you may turn it on (one chime) or off (two chimes) using the STEREO
STEREO
(2-speaker) button.
Using simulated surround for mono movie material
Bose ® Videostage decoding can process a one-channel program into five-speaker sound –
directing the signals so that dialogue remains locked on-screen, while music and ambient
effects fill the room. You experience a surround sensation, providing extra enjoyment when
you watch older (i.e., pre-stereo) movies. This feature can be used for mono TV, FM, and AM
programs. Press the SURROUND
SURROUND
(5-speaker) button to turn it on (one chime) or off (two
chimes). This feature is automatically engaged when a Dolby Digital bitstream indicates that it
contains a mono program.
