Introduction
NuPrime CDT-10 is a highly accurate professional CD player with powerful DSP-based decoder that
provides all Red Book error-correction capabilities with master-clock control of the entire decoding
system, thus lowering jitter significantly. The transport’s single speed minimizes vibration and
unbalanced discs. A selectable sampling rate converter (SRC) up samples the CD format to higher
sampling rate with ultra-low jitter and distortion.
Features
Highly Accurate CD Playback
 A powerful ARM chip LPC2103F CD reads, writes and controls error correction
 Philips SAA7824HL high-end laser reads/writes head control and decodes chips
 Supports CD-DA CD-R, CD-RW
 Algorithm reduces digital interference and jitter
 Coaxial output with a dedicated isolation transformer
 Low jitter I2S output for professional use
Sampling Rate Converter
 The sampling rate of CD playback can be up sampled to PCM and DSD, from 44.1kHz to
768kHz or DoP256
 The conversion is achieved by up-sampling to mega hertz before down converting to the
targeted sampling rate with ultra-low jitter and distortion
Power and Mechanical
