1 Technical Highlights
1.1 Layout
The SACD-Player 746 has two housings, the Player itself and the External Power
Supply.
CD-Player: The analogue circuits are physically separated from
digital circuits. After the Sample-Rate-Converter unit the CD-Player is realized in
pure dual mono layout. Shields between the different sections of the CD-Player ef-
fectively reduce interferences between them.
External Power Supply: The power supplies are located in a separate, external
housing. This reduces potential interferences even further.
1.2 SACD/CD-mechanism
The SACD-Player 746 has a high quality SACD/CD-mechanism (Esoteric UMK-5). In
order to reduce errors from vibrations the drive is mounted on rubber damping ele-
ments.
1.3 DSP (Digital Signal Processor)
A powerful DSP performs the calculations for the upsampling to 24Bit, 384kHz.
The DSD data of a SACD is converted into PCM format during the upsampling pro-
cess. The converted data is extrapolated by a 3
rd order polynomial algorithm. Addi-
tionally this DSP performs computations for the volume control and the balance set-
tings. Thanks to the 32Bit floating comma architecture of the DSP these calcula-
tions go without the usually increase of the quantification noise.
1.4
The SACD-Player 746 incorporates the unique and innovative, DSP based Zero-
Phase-Technology. Every digital to analogue converter requires an analogue low pass
