SKU: USV-AURENDER-W20 Categories: , ,



Designed to be used with high performance digital-to-analog converters, the Aurender W20 is one of the few music servers to support external word clocks – as used in recording studios – plus dual-wire mode AES/EBU used by many reference digital-to-analog converters to separate transmission of left and right channels for better fidelity.

However, even without using the word clock input or dual AES/EBU outputs, the mains-fed battery power supply of the W20 provides a dramatically lower noise floor for a completely silent background, making hum a thing of the past.

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 server 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 long term jitter to below negligible levels and specially designed circuitry provides clean, noise-free power to the dedicated USB digital audio output.

A solid-state caching drive for playback and extensive shielding using thick aluminium partitions also minimize and eliminate the many types of jitter and noise usually associated with the use of disk drives for playback.

Designed to be matched with high-performance digital-to-analog converters (DACs), the Aurender W20 is equipped with various SPDIF outputs (BNC, dual AES/EBU, coaxial and optical) and one dedicated USB Audio Class 2.0 output. For network connectivity and file transfers, the W20 also comes with one a Gigabit Ethernet port and two USB 2.0 data ports.

More Information



Founded in 2011 by Harry Lee, Aurender manufactures high performance, high-fidelity music servers and audio players. Most music servers were conceived as computers with some modifications to become music servers. In this manufacturing model, customers still end up dealing with a computer and all of its inherent hassles. Aurender's philosophy is to remove the hassles that take away from the enjoyment of computer (file) music.

Aurender stands for innovation, refined user experience, and impeccable quality.
