model S303A Compact Disc Player (CD Transport with 16bit Non-‐oversampling DAC)
SEARCH FOR COMPACT DISC PLAYER
The model S303A is a newly designed Compact Disc player based on the 47 Treasure model 0647. It
consists of a single Compact Disc (CD) transport with an external 16 bit non-‐oversampling DAC. The
updated design offers even more natural sound reproduction than the previous model. The model S303A
has a very compact footprint with the same dimensions as a large MOLESKINE® notebook (140 mm wide
x 225 mm deep).
MOLESKINE® is registered trademark of Moleskine Italy
FEATURES
-‐ The model S303A uses a Philips TDA1543 16 bit non-‐oversampling DAC for clear and
vivid soundscape. The model S303A also supports more traditional connection types
between the CD transport and DAC such as S/PDIF (that require intermediate digital
signal conversions).
-‐ The model S303A uses a separate power supply for the CD transport to decrease induction noise from
the transformer and switching noise from rectifiers.
-‐ There is a separate digital power supply for controller and CD transport from analog power supply for
D/A converter.
-‐ A transformer is used for a source of power for the S303A. Using an EI core
transformer instead of a toroidal core transformer results in a more relaxed and
natural sound.
-‐ A discrete transistor regulator is used instead of an IC regulator (3 pins) for clear
and ultra low noise. An IC regulator can be regarded as a type of op-‐amp and is a
source of noise, so we do not use them in audio signal circuits.
-‐ The model S303A supports both an internal and external power supply for the
DAC. The model S303A can be switched from an internal rectified AC line to an
external power source such as an automobile battery or NiMH rechargeable
cell-‐batteries.
-‐ The model S303A front panel controls are user friendly, easy to operate. The front panel consists of a jog
dial and tactile push buttons.
-‐ You can also operate the S303A player from a compact sized remote control (available as an accessory).
The idle current is less than 10µA.
