Realism and impact
Your Lifestyle
®
25 Series II home theater system is equipped with an all new Videostage
®
decoder that uses digital signal processing. The result is increased surround sound realism
and impact both for movie soundtracks and music recordings. Built-in Dolby Digital decoding
of inputs from DVD, digital TV, next-generation cable boxes, and satellite receivers provides
“5.1” capability – up to five discrete audio channels directed into five independent cube
speaker arrays, plus rich bass sound from the Acoustimass module. The Videostage decoder
processes analog formats, as well as two or even single-channel PCM and Dolby Digital
bitstreams, and helps to deliver the acoustic experience of the movies right in your home.
Compatibility
Your system is fully compatible with:
• Digital-audio bitstreams. Look for the symbol
1
or the terms Dolby Digital or
PCM on DVD-Video discs. Your Lifestyle
®
25 Series II system cannot process MPEG-2
or DTS digital bitstreams.
• Surround-sound sources such as VCRs, stereo TVs, cable boxes and satellite
receivers. 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.
• Surround-encoded analog or digital audio signals. Look for the terms Surround or
Dolby Surround, or the symbol
3
on tapes and discs, or the word “surround”
preceding a TV broadcast.
• Stereo program material from TV, FM, CD, and cassette. Videostage decoding
delivers five channels, even when the original source contained only one or two.
• Monaural program material. Videostage decoding can process a one-channel
program into five-channel sound and direct the result to five independent speakers.
Dialogue remains locked on-screen, while music and ambient effects fill the room.
Automatic sound level monitoring and control
Your enjoyment of movies at home is enhanced by Digital Dynamic Range
®
compression. This
technology automatically monitors and 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., a crash or explosion). This feature is especially useful for late night movie viewing – it
eliminates the need for you to constantly adjust the volume level. (See pages 22-23.)
