Design and specifications are subject to change without notice.

The DSD (Direct Stream Digital) format is the core
technology of a Super Audio CD, allowing music
reproduction that is extremely faithful to the original
sound.
The DSD format, using a 2.8224 MHz sampling frequency
64 times higher than that of a conventional CD, and the 1-
bit quantization, makes possible recording of more than
four times the data information of the PCM format which
is used for a conventional CD.
Different from the PCM format which performs data
decimation and interpolation via digital filters, the DSD
format adopts the simple playback process.  In other
words, the A/D converted 1-bit digital signal only passes
through an analog low-pass filter before playback.
As a whole, the DSD format achieves both a wide
frequency range of theoretically over 100 kHz, and a wide
dynamic range across the audible frequency range at the
same time, and results in high-quality music reproduction
faithful to the original sound.
To play back a Super Audio CD recorded in the DSD
format with exceptional quality, the SCD-1/777ES employs 
a newly developed DSD decoder and D/A converter
system, as well as a chassis and loading mechanism
especially designed for this unit.

The SCD-1/777ES can also play back a conventional CD
