The Dac3 fulfills the original promise of digital music reproduction.
It surpasses previous expectations of digital music quality. This
performance results from a unique combination of design techniques,
new technologies and the superb stability of our new Ultra-Clock:
making the Dac3 a one of a kind product in the market.
The
surpassing musical performance rests on the solid foundation of
the Ultra-Clock™, a clock with performance found previously
only from separate Master Clock products. The Ultra-Clock™
provides jitter performance 50x better than other clocks. Specifications
of 1 picoseconds RMS and frequency accuracy of 0.0001% define
new benchmarks in clock stability. This Ultra-Clock™ allows
the Dac3 to reproduce music with new levels dynamic expression
and accuracy of timbre. Your music communicates as never before,
recalling the best of analog music reproduction, without the limitations
of either analog or other digital technologies. The Ultra-Clock™
works in concert with every detail of the Dac3’s design
to achieve a new level of musical realism:
Digital
input isolation and switching
Multi-Stage Jitter rejection
Linear Phase Digital filters
Low noise Digital to Analog conversion
Class A Analog output stage Current to Voltage conversion and
analog filtering
Class A Analog output buffer to drive the preamplifier or amplifier
stage
The Dac3 has been optimized to provide the highest level of performance
for all of these critical functions. It can provide digital preamplifier
as well as D/A conversion and bridge from traditional CD or DVD
player sources and from the isolated USB input for computer music
playback sources. The Dac3 has 5 digital inputs:
AES
with transformer coupled input for high common-mode noise rejection
in professional environments.
Transformer isolated SPDIF RCA input.
Transformer Isolated SPDIF BNC input.
Wide bandwidth TOSLINK input for versatile interface to consumer
grade equipment.
USB input with galvanic isolation for optimized connection to
a computer based music source with ground and power isolation
between the computer platform and the audio system.
All digital input sources experience 2 jitter rejection stages,
one analog PLL stage at the SPDIF input and a second digital PLL
stage at the Sample Rate conversion/filter stage. The new algorithm’s
170 dB of digital dynamic range insures a totally transparent
conversion to 24/192 data rate for the final DAC processing. The
Ultra-Clock™ used for the D/A conversion is located at the
output of the sample rate conversion stage. The USB input goes
through a 3rd de-jitter stage to insure optimum playback from
computer based sources.
The
PCM1792 dual-differential multi-bit delta-sigma DAC circuit achieves
remarkable analog performance. The 4.5VRMS true balanced XLR outputs
provide nearly 130dB of dynamic range. The noise floor of this
DAC/processor is so low and so clean that the Dac3 is optimally
used as a complete DAC/Preamplifier with a digital level control.
Because of dither applied to the 24bit word there is no loss of
effective resolution. The application of optimized dither insures
that the analog output noise floor maintains a clean sound, devoid
of any a-musical tones or artifacts. In a system with digital
sources the Dac3 can provide an optimum solution with the addition
of one of the Bel Canto e.One amplifier products, eliminating
the analog preamplifier.
