Accuphase :: DC-950 mdsd Precision Digital Processor

DC-801 Precision Digital Processor

Digital processor designed for ultimate SA-CD quality. Innovative digital signal processing technology MDSD (Multiple Double Speed DSD). Moving-average filter circuit configured with delay and eight parallel converters achieves straight D/A conversion of DSD signal. Seven digital inputs for enhanced versatility.

The DC-950 showcases Accuphase´s mastery of sophisticated digital technology and creative circuit topology. It is a digital processor designed to realize the ultimate in SA-CD reproduction.

A new technique called MDSD (Multiple Double Speed DSD) allows straight D/A conversion of the DSD signal. MDSD employs eight MDS++ type D/A converters operating in parallel to reduce conversion errors to an absolute minimum while at the same acting as a high-cut filter that removes noise in the high-frequency range. The Direct Balanced Filter is configured with entirely separate balanced and unbalanced signal paths, and a further refined "Ultra Jitter-Free +" PLL circuit extracts the master clock for the D/A converter with absolute precision. The overall result is music reproduction that finally brings out the full sonic potential of the SA-CD format.

For connectivity to various sources, the DC-950 offers a full complement of digital inputs: HS-Link, balanced, coaxial (3 streams), and optical (2 streams). This allows the music data to be supplied to the processor without any degradation in quality. Two sets of digital outputs (coaxial and optical) let the user easily connect a digital recorder, for recording of sources other than SA-CD. And there´s even a set of EXTERNAL DSP input/output connectors that allows using the Digital Voicing Equalizer DG-48 for sound field processing in the digital domain.
