When computer audio first started to gain popularity, USB was the de facto standard for the digital audio signal transport. This was simply because computers have USB ports, not AES/EBU or other SPDIF ports. Unfortunately, USB can be a flawed protocol for digital audio transmission as it is prone to noise, jitter, and compatibility issues. Done properly, AES/EBU and SPDIF audio outputs represent a superior method of audio transmission with nearly universal compatibility, less jitter, and greater ease and flow to the overall musical presentation. N10 represents the state-of-the art of these protocols with its OCXO controlled SPDIF outputs – use them and discover a higher standard than USB.
Ultra High-Quality SPDIF and AES/EBU Digital Audio Outputs
N10’s AES/EBU, BNC, Coaxial, and Optical outputs provide a superior musical presentation. As opposed to an asynchonous USB connection, where the DAC pulls packets of information from the player, N10’s SPDIF and AES/EBU audio outputs push signal out to the DAC at intervals defined by the on-board OCXO clock. With a clock this precise, trust us, you want to use it!
Oven-Controlled Crystal Oscillator (OCXO) for Long-Term Jitter Reduction
OCXOs are among the most accurate and stable clocks in use today, and 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.
Precision DSD-to-PCM Conversion by FPGA
Many DACs support DSD decoding only on their USB inputs and not on SPDIF or AES/EBU. That’s why the Aurender N10 (and W20) feature an extremely high-quality DSD-to-PCM conversion by FPGA.
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.
4TB Hard Disk Drive Storage with Solid-State Drive Cache for Playback
Internal hard drives provide either 4TB 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 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.
USB HDD and NAS (Network-Attached Storage) Support
Best performance occurs when music is stored on the Aurender’s internal storage. However, the Aurender platform is also capable of seamlessly integrating content stored on a NAS or external USB hard drive.
Aurender Conductor App Packed with Convenient Features for Full-Function Control
The Aurender Conductor App turns the iPad into a versatile user interface for Aurender music servers. All settings and functions of the Aurender server can be easily accessed through the Settings menu, and the app comes with extensive features to make browsing and playing high resolution music collections a breeze.
MQA Core Decoder (optional in-app purchase)
Aurender’s optional MQA Core Decoder upgrade enables “first-level” MQA unfolding to play MQA files at up to 48 or 96 kHz.
Remote Internet Technical Support
Sending a Remote Support Request through the Aurender App allows engineers to quickly diagnose and correct problems over the Internet.
