makes the Super Audio CD and player?
Sony and Philips Electronics are responsible for
the creation of the Super Audio CD. Currently, Sony, Philips, Marantz,
Accuphase, Denon, Kenwood, Aiwa, and Sharp are manufacturing SACD players.
When can I buy
an SACD player?
Super Audio CD was launched in early September
1999. SACD players are now available for purchase in the United States and
around the world.
Where can I buy
SACD software can be found at traditional retail
What is the
technology behind SACD?
The sound of SACD comes directly from Direct Stream
Digital (DSD) recording technology. DSD's simplified mechanism for
recording and playback results in a frequency response of over 100kHz and
a dynamic range over 120dB across the audible frequency range. DSD
increases the resolution of music by more closely following the original
wave form of the music, which results in music reproduction that is
remarkably pure and faithful to the original. For additional information

What are the benefits
In addition to exceptional sound quality through the DSD system, the SACD
format can accommodate more than four times the information of the current
CD format. With this extra capacity, a standard Super Audio CD will
provide space for 2-channel stereo data, as well as an area for up to
6-track multi-channel data, storage capacity for text and images, disc
variations, copyright protection and much more.
Will my current
CD collection play on an SACD player?
Yes. Super Audio CD players can play back all
Can I play a
Super Audio CD on my current CD player?
Currently, SACDs from Sony Music must be played on
a super Audio CD player. Specifically, Sony's SACD titles are not hybrid
discs [i.e., the discs contain one high-density (HD) layer but do not
contain a CD layer]. SACDs from the specialty labels can be played on
current CD players.
What is SACD
SACD multi-channel sound can contain as many as six
separate channels, each captured on disc at the full DSD bit rate with the
full DSD sound quality. Some producers will use the added channels to
faithfully reproduce the precise acoustic signature of the performance
space. Others will realize new creative possibilities, immersing the
listener in a 360° field of sound. Multi-channel SACD takes its place
beside stereo SACD as another compelling way to enjoy music.
What is the ITU
One valuable guideline for multi-channel recording
and speaker set-up is the ITU standard. It positions the listener at the
center of a circle of speakers. The center speaker is located at 0°. Left
and right are at ±30°, forming an equilateral triangle with the
listener. Left surround and right surround speakers are positioned at ±110°,
with tweeters at or slightly above ear level.
