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.
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.
