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 Definition Compatible Digital
®
) is a
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 flat, digital
imitation.

Dolby Digital identifies the use of Dolby Digital
audio coding for such consumer formats as DVD
and DTV. As with film sound, Dolby Digital can
provide up to five full-range channels for left,
center, and right screen channels, independent left
and right surround channels, and a sixth ( ".1")
channel for low-frequency effects.
Dolby Surround Pro Logic II is an improved matrix
decoding technology that provides better spatiality
and directionality on Dolby Surround program
material; provides a convincing three-dimensional
soundfield on conventional stereo music recordings;
and is ideally suited to bring the surround experience
to automotive sound. While conventional surround
programming is fully compatible with Dolby Surround
Pro Logic II decoders, soundtracks will be able to be
encoded specifically to take full advantage of Pro
Logic II playback, including separate left and right
surround channels. (Such material is also
compatible with conventional Pro Logic decoders.)
Dolby Digital EX creates six full-bandwidth output
channels from 5.1-channel sources. This is done
using a matrix decoder that derives three surround
channels from the two in the original recording.
For best results, Dolby Digital EX should be used
with movies soundtracks recorded with Dolby
Digital Surround EX.
