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 used in recording studios, and dual-wire mode used by many reference digital-to-analog converters to separate transmission of left and right channels for better fidelity.
With 12TB of (6TBx2) 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.
External Word Clock Support
Word Clocks are used in recording studios to synchronize timing between devices and ensure jitter-free and time-perfect data transmission.
It supports both word clock (dCS DACs or similar) or Master Clock.(MSB DACs or similar)
Dual-wire AES/EBU Mode
Dual-wire AES/EBU mode is used by many reference digital-to-analog converters to separate transmission of left and right channels for ultimate fidelity.
For example, when Dual AES/EBU mode is used, left and right chanel is transmitted at 96kHz rate to make 192kHz stereo transmision.
Since the max frequency is halved, transmission line requirement becomes less strict.
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.
Internal UPS to protect the storage from the unexpected power outage
Oven-Controlled Crystal Oscillator (OCXO) for long term jitter reduction
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. Moreover, 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 times digital audio data transmissions and minimizes jitter to below negligible levels
12TB Hard Disk Drive Storage with Solid-State Drive Cache for Playback
An internal hard drive provides 12TB 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, electrical and acoustic noise resulting from spinning disks, moving heads and motors are also completely eliminated.
Dedicated USB Audio Class 2.0 Output with Ultra Low Noise 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 off depending on the USB DAC’s requirement.
Quality Fanless Switching Mode Power Supply (SMPS for CPU board)
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 with its own Aluminum casing
The internal hard disk drives are suspended on floating brackets to minimize vibrations and housed in a machined aluminum compartment for complete isolation.
AMM and NAS(Network-Attached Storage) Support
If you already have NAS set-up, the Aurender W20 is able to play music stored on NAS devices,
AMM(Aurender Media Manager) software is available for Mac(OS X 10.9 or later) now. Windows version will be available later.
You can run AMM software on your platform of choice, please specify the location of your content on NAS then it will automatically find the Aurender in you local network and make a combining music database. It's transparent to the user, so once you run AMM , you can select the music with all the meta-data using the Aurender Conductor App without the knowledge of the location of your music files.
Remote Internet Technical Support
Sending a Remote Support Request through the Aurender App allows engineers to quickly diagnose and fix problems over the Internet.
