Like Compact Disc applications, SACD
players are developed around an optical laser unit
which reads digital information from a disc and
forward them to a servo-decoding board. As a result,
this board provides subcode information to the user
section, audio streams to the digital-to-analogue
conversion board, ...
However, unlike Compact Disc, SACD discs are based
on new technologies in order to provide a much
better audio quality: DSD conversion to 1-bit
resolution with a 2.2884MHz sampling frequency,
improved dynamic range (greater than 120dB across
the audio band) and frequency response ranging from
DC to 100kHz. SACD consequently offers a far better
musicality, after digital-to-analogue conversion,
than standard CDs or any other optical media in the
audio market. Multi-channel possibility,
watermarking copy-protection and hybrid discs are
also part of the SACD success in the high-end audio
domain. More information on SACD can be found in the
technology pages of the DAISy site.
For OEM applications, a range of complete SACD
modules will be proposed. These modules are the
result of many years of experiences that DAISy got
in the optical reading systems. Thus, it includes
the latest technologies in order to assure the best
playability with optical discs. Such playability is
also guaranteed by the careful attention which has
been paid to EMC during the design phase of the
servo board. Finally, this range of SACD modules
will offer the latest options as regard to audio
decoding: Super Bit Mapping Direct Conversion,
frequency over-sampling,...
Because CD and SACD are based on similar optical
reading technologies, the applications using these
modules are often high-end audio players which
provides an excellent audio quality with both
formats, CD & SACD. Besides, an audio
manufacturer can bring his know-how in order to
improve the digital-to-analogue section of the
player.
Thanks to the modularity of the GyrFalcon concept,
our range of SACD modules can be used with different
loading systems (metal loaders, Slot-in mechanism),
various displays kits with the most sophisticated
technologies, dedicated Power Supply Units, and many
other additional possibilities (D to A conversion
modules, SACD remote control handsets) : the aim of
our products is to avoid to manufacturers a long and
expensive software and hardware development and to
reduce time to market for the launching of their
players.
