NAD D 1050 USB DAC Datasheet
D 1050
USB DAC
Our D 1050 USB DAC is the best way to add Computer Audio
and HD Digital to your component hi-fi system. In fact, all digital
sources will get a boost when the D 1050 takes over for the
inferior digital circuitry found in everything from Blu-ray, DVD
and CD players, to music streamers and set-top boxes. Both
the digital and the analogue circuits are highly optimised and
based on techniques developed over 40 years of NAD audio
engineering excellence. There is no reason to sacrifice audio
quality for convenience, as our D 1050 so vividly demonstrates.
> Totally Connected
The D 1050’s digital inputs allow you to connect many different
digital sources. SPDIF inputs support both coaxial and optical
connectors. The USB input is very special—its asynchronous
operation mode uses the D 1050’s high precision clock to
control the output of the connected USB device for lowest
possible jitter. It also supports USB Audio Codec 2.0 allowing
192kHz signal transmission via USB.
> Making it Count
We packed a lot of premium high spec parts inside the D 1050
USB DAC. But premium parts need optimal implementation to
get the actual performance they promise. This is where NAD’s
expertise with both digital and analogue circuits shows its true
value. Ultra short impedance-controlled signal paths are made
possible by multi-layer circuit boards and micro-miniaturized
surface mount components which are soldered with lead-free
high silver content solder. We also found that we could further
reduce noise by isolating the power supply from the sensitive
analog circuitry by using a highly efficient external type. These
details all contribute to the remarkable performance of this
advanced DAC.
> Magic from a DAC
The digital processing of the D 1050 features Delta/Sigma
architecture with active oversampling filters. This technique
effectively reduces out of band noise while maintaining linear
phase response and virtual elimination of filter ringing in the
pass band. This assures detailed and extended high frequency
response while taking full advantage of the extended response
of recordings sampled at 88.2kHz, 96kHz, 172.4kHz and
192 kHz. Separate precision clocks fed from pristine DC
supplies keep jitter (digital timing errors) to an absolute
minimum. Everything is bit perfect; we do not upscale or
downscale sample rates, and the incoming sample rate is
indicated on the front panel display.
> The Perfect Mix
Analogue outputs are fixed for highest resolution and include
both balanced and single-ended connections. The D 1050 also
includes a premium discrete headphone amplifier output with
a high quality volume control. Output impedance is extremely
low, minimizing the effect of connecting cables and keeping
noise vanishingly low.
> GREEN, GREEN, GREEN!
In designing our D 1050, our NAD team focussed on finding
new technologies that can improve musical performance while
requiring less power to operate and fewer non-renewable
resources to manufacture. The D 1050 is a DAC you’ll be proud
to own.
