HDCD
®
: The High Definition Compatible Digital
®
(HDCD) process is a sophisticated
dynamic-range-expansion and frequency-resolution enhancing algorithm used when
recording and playing back a CD, allowing much greater resolution and dynamic range
than previously possible. As much as 20 bits of musical resolution can be achieved with the
HDCD process, rivaling the highest-quality analog master tapes.
Developed by Pacific Microsonics, the HDCD process was designed to match the ultimate
resolving power of the human ear, while maintaining compatibility with the existing 16-bit
CD format. Moreover, even non-HDCD discs are played back with exceptional clarity,
because the HDCD hardware acts as an ultra-high-quality digital filter when a non-HDCD
disc is played.
•
Six precision Burr Brown PCM1702 20-bit DACs provide excellent low-level linearity
and dynamic range.
•
AccuLinear
®
analog circuitry provides superior reconstruction of the musical waveform.
This advanced technology incorporates discrete components within a single chip wafer to
provide greater speed and accuracy than either discrete or conventional integrated designs
can provide. This results in reduced transient distortion in the critical current-to-voltage
stage—a principal cause of harshness, glare and stridency commonly associated with CD
sound.

Digital Flywheel ™
reclocking circuitry is a state-of-the-art, proprietary, dual time constant
phase locked loop, utilizing
two
precision, voltage-controlled crystal oscillators (VCXOs)—
for both 44.1 kHz and 48 kHz. The electronic equivalent of a massive rotating flywheel,
Digital Flywheel
smooths out instantaneous time-base fluctuations (i.e., jitter), achieving up
to a thousand-fold reduction in high-frequency jitter. This unrivaled jitter performance is
especially crucial in achieving the ultimate musical resolution and soundstage focus made
possible by DTS and by the HDCD process.
•
Balanced stereo outputs utilize separate DACs for + and - polarity to achieve lowest
possible THD and greatest signal-to-noise ratio.
•
Remote volume control utilizes switched resistive array for ultimate transparency. Vol-
ume adjustable in 0.2 dB steps.
