English Reality reproduced: Super Audio
CD
The future in digital sound reproduction is no
longer limited to a close simulation of reality. The
new audio standard IS reality! The human ear is no
longer capable of distinguishing audible reality
from digital reproduction. This Super Audio CD
player combines superior sound quality with the
possibility of playing almost all existing audio and
video formats with a single player.
The Super Audio standard is based on Direct
Stream Digital (DSD) technology. This new
direct-stream digital format comprises a 1-bit
system that has a digital sampling frequency that is
64 times higher than that of conventional audio
CD. The results are spectacular: a frequency
response of over 50k Hz and a 120dB dynamic
range over the entire audible spectrum. Mixed
with as many of the original frequencies as
possible, the audio information audible for human
ears sounds much more natural.
The next standard: hybrid disc
The Super Audio CD is the evolution of the CD
that provides ultra-high-quality sound. Additional
features, including multi-channel, can be offered.
On the high density (HD) Super Audio CD you
may have access to separate areas, containing
two-channel stereo and multi-channel.
But that is not all! The hybrid version of the SACD
guarantees backward compatibility with the
installed base of CD and DVD players. In addition
to the HD layer, the hybrid disc contains a
standard density CD layer with conventional two-
channel stereo CD audio information. The two
layers are read from the same side of the disc. The
HD layer is read by and DVD laser. The bottom
reflective layer with conventional CD sound is
read by the CD laser through the second, semi-
transmissive HD layer.
SACD: reality in sound...and
vision
This SACD player will not only surprise you with
its superior reproduction of almost all existing
audio formats. Connected to your TV, your
SACD player presents VCD and DVD-video
information as perfect digital studio-quality images
with truly 3-dimensional digital multi-channel
audio.
Super Audio CD
You will recognize Super Audio CDs by the logo.
There are three types of Super Audio CDs: single-
layer, dual-layer and hybrid discs. Each type may
contain two areas of recorded information: a High
Quality Stereo area and a High Quality Multi-
channel area.
– The single layer disc may contain both
information areas.
– The dual layer disc may contain both
information areas but a double amount of
information can be stored on the disc thanks
to the second layer.
– The hybrid disc may contain not only both
information areas but also a second, standard
CD layer, making it playable on standard CD
players.
Recorded information may vary per area. This is
indicated in the disc inlay. Areas can be selected
separately before or during playback, while playing
Super Audio CDs via the remote control or via
the On-Screen Display on your TV.
