Dolby Virtual Speaker is a technologycertified
by Dolby Laboratories that creates a virtualized
surround sound experience from two speakers using
a multichannel Dolby Digital source. Additionally,
Dolby Virtual Speaker can simulate the surround
sound effect produced by Dolby Pro Logic or Dolby
Pro Logic II.
Dolby Virtual Speaker retains all the original
Multichannel audio information and provides the
listener with the sensation of being surrounded by
additional speakers.
Dolby ® TrueHD is Dolby's next-generation lossless
technology developed for high-defi nition disc-based
media. Dolby TrueHD delivers tantalizing sound
that is bit-for-bit identical to the studio master,
unlocking the true high-definition entertainment
experience on next-generation discs. When coupled
with high-defi nition video, Dolby TrueHD offers an
unprecedented home theater experience that lets
you enjoy sound as stunning as the high-defi nition
picture.
Dolby Digital Plus is a highly sophisticated and
versatile audio codec based on Dolby Digital and

Circle Surround II® (CS-II) is a powerful and versatile
multichannel technology. CS-II is designed to enable
up to 6.1 multichannel surround sound playback
from mono, stereo, CS encoded sources and other
matrix encoded sources. In all cases the decoder
extends it into 6 channels of surround audio and a
LFE/subwoofer signal. The CS-II decoder creates
a listening environment that places the listener
"inside" music performances and dramatically
improves both hi-fi audio conventional surround-
encoded video material. CS-II provides composite
stereo rear channels to greatly improve separation
and image positioning– adding a heightened sense
of realism to both audio and A/V productions.
CS-II is packed with other useful feature like dialog
clarity (SRS Dialog) for movies and cinema-like bass
enrichment (TruBass). CS-II can enable the dialog
to become clearer and more discernable in movies
and it enables the bass frequencies contained in
the original programming to more closely achieve
low frequencies–overcoming the low frequency
limitations of the speakers by full octave.
