Designed to be used with high
performance digital-to-analog
converters, the Aurender W20 is one
of the few music players to support
external word clocks often used in
studios and dual-wire mode, used by
many reference digital-to-analog
converters to separate transmission
of left and right channels for
better fidelity.
The Aurender W20 supports up to
24-bit, 192kHz playback on the SPDIF
outputs and is compatible with DSD (DSF,
DFF), WAV, FLAC, AIFF and other
major formats. With 6TB of storage
on two internal hard disk drives and
one 240GB solid-state drive cache
for playback, the W20 is the perfect
solution for even the most extensive
high resolution music collections.
Innovative Technology
In digital audio, jitter and
noise in the audio signal can
seriously affect the performance of
digital-to-analog converters. The
Aurender W20 is the world's first
music player to completely eliminate
noise from AC power supplies and AC
mains through the use of LiFePO4 (LFP)
batteries to power audio components.
An FPGA-based All Digital Phase
Locked Loop system with an
Oven-Controlled Crystal Oscillator (OCXO)
clock is used to maintain jitter to
below negligible levels and
specially designed circuitry
provides clean noise-free power to
the dedicated USB digital audio
output. A solid-state drive cache
for playback and extensive shielding
using thick aluminum partitions also
minimize and eliminate the many
types of jitter and noise associated
with the use of disk drives for
playback.
Full Range of Digital Audio
Outputs and Ports for Network
Connectivity
Designed to be matched with high
performance digital-to-analog
converters, the Aurender W20 is
equipped with various SPDIF outputs
(BNC, AES/EBU, coaxial, optical) and
one dedicated USB Audio Class 2.0
output. For network connectivity and
file transfers, the W20 comes with
one Gigabyte Ethernet port and two
USB 2.0 data ports.
Separate LiFePO4 (LFP) Battery
Power Supply for Audio Components
Two banks of LiFePO4 batteries
alternately power audio components
and recharge. This completely
isolates audio components from
ground noise and also eliminates
jitter incurred in converting AC to
DC. A third bank of batteries acts
as an Un-interruptible Power Supply
(UPS) and should any sudden power
outages occur, the Aurender W20 will
shut down safely.
Oven-Controlled Crystal
Oscillator (OCXO)
OCXOs are among the most
accurate and stable clocks in use
today. OCXOs are orders of magnitude
more accurate and stable than
commonly used ordinary crystal
oscillators usually found in
computers. Temperature changes cause
crystal oscillations to fluctuate
which can lead to jitter in the
digital audio signal. In addition,
ordinary crystals are much less
stable and lose accuracy over time.
In OCXO clocks, a very stable high
grade crystal oscillator is enclosed
in a compartment and kept at a
constant temperature to prevent
jitter from temperature fluctuations,
FPGA-based All Digital
Phase-Locked Loop System
An All Digital Phase-Locked Loop
system (ADPLL) incorporating
Field-Programmable Gate Arrays (FPGA)
with OCXO clocks precisely time
digital audio data transmissions and
minimize jitter to below negligible
levels.
Hard Disk Drive for Storage with
Solid-State Drive Cache for Playback
An internal hard drive provides
up to 6TB of storage and a 240G
solid-state drive is used to cache
music for playback. If a selected
song or album is already cached to
the solid-state drive, the hard
drive will remain asleep. This
minimizes wear and tear on the hard
drive. By caching songs to the
solid-state drive for playback,
jitter and noise resulting from
spinning disks, moving heads and
motors are also completely
eliminated.
Dedicated USB Audio Class 2.0
Output with Noise Free Power
Circuitry
The dedicated USB Audio Class
2.0 output is designed to deliver an
exceptionally transparent audio
signal free of noise and is shielded
from outside electronic interference.
When not in use, the power to the
USB Audio output can be shut offf
for improved fidelity.
Fanless Switching Mode Power
Supply (SMPS)
A fanless Switching Mode Power
Supply delivers stable power to
non-audio components and is enclosed
in a separate compartment to prevent
any interference to other components.
Isolated and Damped Hard Disk
Drives
The internal hard disk drives
are suspended on floating brackets
to minimize vibrations and housed in
a machined aluminum compartment for
complete isolation.
Supports Network-Attached Storage
(NAS)
The Aurender W20 is able play
music stored on NAS devices, should
there be a need for more storage
capacity,
Remote Internet Technical Support
Sending a Remote Support Request
through the Aurender App allows
engineers to quickly diagnose and
fix problems over the Internet,
should they occur.
Aurender iPad App
The Aurender iPad App is the
culmination of years of
collaboration with Aurender owners
and industry partners in order to
better satisfy user needs. Full of
convenient and easy-to-use features
that put music collections at the
control of your fingers, the
Aurender App enables even the
largest music collections to be
easily viewed, managed and played at
the press of a button. The Aurender
App is frequently upgraded to
provide the latest features and
improvements and can be
downloaded from the App Store
free of charge.
