Aurender Music
Systems are one of the first systems
to employ playback from Solid State
Drives which provide performance
unmatchable by CD players and Hard
Disk Drives. The OCXO oscillators
used in Aurender S30 Music Systems
are 10,000 to 100,000 times more
accurate than ordinary crystal
oscillators used in most music
servers and players. The easy-to-use
iPad* user interface, up to 6
terabytes of memory and other unique
features, make the Aurender S30
Music System the ideal music storage
and playback solution for
discerningmusic lovers.
Features
- Free iPad* remote control
application from Apple* App Store
- Customized Linux OS for best audio
performance
- WAV, FLAC, APE and other formats
supported
- Up to 24-bit width and 192 kHz
sampling rate
- Switching-mode and linear power
supplies
- Playback from Solid State Drive
- Silent fanless design
- AMOLED displays.
Aurender iPad App
Using the Aurender App, the
easy-to-use iPad* becomes the master
control for the Aurender Music
System. The large display allows for
quick viewing and search of even the
largest music collections. The
Aurender Application for iPad* is
free and can be downloaded from the
Apple* App Store.
Convenient Features
- Intuitive search function for fast
easy selection
- Make and edit playlists with just
a touch of one's finger
- All details of song, album,
playlist and queue easily viewed on
large iPad display
- Automatic or custom categorization
of songs
- CD album front and back covers can
be stored and displayed along with
music
selection
- Web search function to search for
information on selected artist or
song
- Zoom in function
Technology
Aurender uses a customized Linux
operating system tuned for high
performance digital processing. In
addition, sampling rates from
44.1~192KHz with 16-bit and 24-bit
widths match or vastly exceed the
audio quality that can be obtained
from compact disks.
With today's technology, clock and
signal jitter can be lowered to a
point where their effects are
negligible. Ordinary crystal
oscillators have an accuracy of 10-4
to 10-5. Temperature Compensated
Crystal Oscillators (TCXO) have an
accuracy of 10-6. Oven Controlled
Crystal Oscillators have an accuracy
of 10-7 to 10-8. The next higher
performance oscillators are based on
Rubidium or Cesium and are used to
make atomic clocks. OCXO clocks are
10,000 to 100,000 times more
accurate than ordinary crystal
clocks and the sound quality
difference is very noticeable. In
the Aurender S30, an OCXO clock and
proprietary reclocking with
Field-programmable Gate Arrays (FPGA)
are combined to ensure virtual
jitter free performance and superb
audio performance.
The Aurender Music System is fanless
to eliminate vibrations, unwanted
electromagnetic fields and noise
emanating from the fan. Solid State
Drives, which have no moving parts,
are used to avoid vibrations,
electromagnetic interference, and
latency found in hard disk drives.
The use of solid-state drives vastly
lowers processor access times.
During playback, selections are
automatically cached using
proprietary technology from the hard
disk to the Solid State Drive. The
hard disk then falls asleep and the
music is played back using only the
solid state drive. This design
eliminates problems with sonic and
electromagnetic noise from spinning
hard disk drives.
Usually users will listen to a
limited selection of songs for a few
months. In this case, the HDD will
rarely move to transfer data to the
SSD. It is mostly on the SSD. The
less the HDDs move, the less the
disk bearings move. Worn out disk
bearings are the usual cause of HDD
failures. The rate of data transfer
to the SSD is limited to 50MB/sec.
due to the mechanical design of the
HDD. The fastest option would be to
use SSDs for both storage and
playback, but due to the high costs
of SSDs at present, it will be years
before this option is economically
feasible.
Care must also be taken when using
switched-mode power supplies which
generate undesirable electromagnetic
noise. In the Aurender Music System,
power is provided by both switching
mode and linear power supplies. The
switching mode power supply is
isolated from critical components
using thick aluminum walls and the
linear power supply is used for
sensitive critical components. Thick
aluminum is also used to isolate
physical and electromagnetic noise
from CPUs and hard disk drives.
The Aurender S30 Music System
delivers the best audio performance
possible. The superior audio quality
is definitely distinguishable even
when compared to much more expensive
high end systems.
Connections
The Aurender S30 Music System has
digital outputs (Coaxial, AES/EBU,
Optical) which are designed to be
connected to a Digital-to-Analog
Converter (DAC), or an amplifier
with digital inputs. The Aurender
must be connected to a wireless
router in order for the iPad to
function as a wireless master
control. |
