Vivaldi DAC uses the latest
groundbreaking dCS technology
including ‘next generation’ versions
of the dCS Ring DAC™, Digital
Processing Platform and Clocking
System so that, as the hub of a
digital audio system, an array of
features guarantees superlative
performance from any digital source.
Vivaldi
DAC features standard AES3, Dual AES,
SDIF-2 and S/PDIF inputs in addition
to an asynchronous USB 2.0
interface. The enhanced digital
volume control allows direct
connection to a power amplifier so
that in the majority of systems
there is no need for a separate
preamplifier. Maximum output can be
set at either two or six volts to
suit different amplifier and speaker
combinations.
The unique design of the legendary
dCS Ring DAC™ combines exceptional
linearity with very high speed
operation enabling it to deliver
true 24-bit performance even at low
signal levels. The latest generation
of our proprietary Ring DAC™
incorporates a number of important
technical advances that have
resulted in enhanced dynamic range,
reduced jitter, improved channel
separation and greatly improved
musical realism.
The powerful digital processing
platform of Vivaldi DAC is based
around Field Programmable Gate Array
(FPGA) chips, Digital Signal
Processing (DSP) chips and a
microcontroller system. All use code
developed and maintained in the UK
by dCS. Offering twice the logic
capacity of previous generations,
Vivaldi DAC is the current
state-of-the-art in digital audio
and delivers unmatched sonic and
measured performance.
dCS pioneered the use of external
clocks in digital audio systems, and
the redesigned multi-stage
Phase-Locked-Loop (PLL) system used
in Vivaldi DAC sets world-beating
standards for accuracy and control
of troublesome jitter from the
incoming audio stream.
Featuring a completely new interface
designed to handle all high
resolution musical formats up to DXD
(24-bit data at 352.8 and 384kS/s)
plus DSD/64 or DSD/128, the
optimised DSP filters available to
Vivaldi DAC owners will ensure you
can extract every last nuance of
musical detail and emotion by tuning
the system to suit your personal
preference.
The dCS ‘soft’ approach to
programmable logic makes it
extremely easy for users to update
Vivaldi DAC software, whether adding
new features, installing performance
upgrades or adapting to changes in
digital formats.
Used as a standalone DAC or as part
of a complete Vivaldi digital audio
playback system Vivaldi DAC gives a
performance of effortless realism
each and every time.
Key Features

-
The interface
runs in asynchronous USB mode,
making the DAC immune to jitter
from noisy computer master
clocks.
-
Improved
power supplies give lower
running temperature and superior
tolerance to AC supply
variations.

Multi-stage
regulation ensures sensitive
analogue circuitry is unaffected
by digital interference.
-
Separate
power circuits for the digital
and analogue sections further
enhance the purity of the power
supply.
-
Aerospace-grade machined
aluminium chassis fitted with
tuned acoustic damping panels
reduces magnetic effects and
vibration.
