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.

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.

HDCD ® (High Defi nition Compatible Digital
patented process for delivering on Compact Disc the
full richness and details of the original microphone
feed.
HDCD encoded CDs sound better because they are
encoded with 20-bits of real musical information as
compared to 16-bits for all other CDs.
HDCD overcomes the limitation of the 16-bit CD
format by using a sophisticated system to encode
the additional four bits onto the CD while remaining
completely compatible with the CD format.
When listening to HDCD recordings, you hear more
dynamic range, a focused 3-D sound stage, and
extremely natural vocal and musical timbre. With
HDCD, you get the body, depth and emotion of the
original performance not a fl at, digital imitation.
