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. At Philips the future
starts today with the Super Audio Compact Disc
player. 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.

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.
