Audiobyte SuperHUB Multifunctional Streamer native I2S

Audiobyte SuperHUB Native I2S Multifunction Streamer

Crafted from a single block of high-quality aluminum, featuring a 3-inch IPS display with a wide viewing angle, linear power supply, dedicated FPGA audio hardware, high-quality programmable clocking, and based on a lightweight custom Linux system to ensure consistent sonic performance. It fully supports Roon, UpnP, DLNA, OpenHome, and comes with dedicated control apps for iOS and Android.

The Audiobyte SuperHUB is designed as a carefully engineered digital hub, capable of seamlessly integrating multiple digital sources into a single unit. Advanced digital signal processing, including reclocking and upsampling (transcoding), takes place entirely in the digital domain before transmitting optimized data streams to an external DAC.

Many enthusiasts also use it to upsample traditional PCM encoding into high-frequency DSD. The SuperHUB’s ultra-efficient FPGA-based audio engine performs powerful upsampling, eliminating the need for a bulky computer within the audio system.

Chassis

With such specialized hardware, we had to push the boundaries in chassis design as well, creating an enclosure machined from a solid block of aluminum, precision-engineered to house our components. The result is a combination of aesthetics and functionality that ensures high structural integrity, effective cooling, and vibration resistance, all within a design that minimizes seams and joints. Before anodizing, the chassis undergoes a sandblasting treatment that provides a smooth matte surface capable of blending elegantly into any audio system.

Operating Modes

For all of its inputs, especially traditional digital formats such as SPDIF and AES/EBU, the SuperHUB employs a robust jitter reduction technique. By leveraging Audiobyte’s proprietary technology based on digital PLLs and buffering stages, it achieves remarkable input jitter reduction of up to -60 dB.

A Phase-Locked Loop (PLL) is an electronic circuit equipped with a voltage-controlled oscillator that continuously adjusts itself to match the frequency of an incoming signal. PLLs are used to generate, stabilize, modulate, demodulate, filter, or recover signals from noisy communication channels where data may have been disrupted or interrupted.

Control: intuitive navigation through the capacitive IPS touchscreen, complemented by easy-to-use Android and iOS control applications.

At the heart of the SuperHUB lies a seventh-generation AMD ZYNQ SoC (system-on-chip), integrating both hardware and software operations within a single chip. Although the countless hours of hidden development may not be visible, the result is unmistakable: a smooth and uninterrupted musical flow that delivers long-lasting listening enjoyment.

Unlike competitors relying mainly on RPi-based streaming products or standard hardware modules, the SuperHUB is built entirely from the ground up on Audiobyte’s proprietary hardware platform. To achieve the best possible performance, we designed and developed a brand-new motherboard from scratch, featuring a custom 10-layer PCB that allowed our engineers to optimize signal routing. Combined with a linear power supply, this ensures perfect synergy between the audio hardware and CPU, culminating in an exceptional sonic experience.
