AudioByte SUPER HUB I2S USB

Native I2S Multifunctional Streamer

Crafted from a single block of premium aluminium, featuring a 3-inch IPS wide-angle display, a linear power supply, dedicated FPGA audio hardware, high-quality programmable clock, and powered by a custom lightweight Linux system to ensure unwavering sonic performance. Seamlessly supports Roon, UpnP, DLNA, OpenHome and comes with dedicated iOS and Android control apps.

The Audiobyte SuperHUB stands as a meticulously designed digital hub, seamlessly uniting your various digital sources into one unit. Advanced digital signal conditioning, including reclocking and upsampling (transcoding), takes place in the digital domain before transmitting the refined data streams to an external DAC.

For all its inputs, particularly traditional digital formats like SPDIF and AES/EBU, SuperHUB employs a robust jitter elimination technique. Leveraging Audiobyte’s proprietary technology centered on digital PLLs and buffer stages, it achieves an impressive up to -60 dB reduction in incoming jitter.

Conventional high-performance computers are bulky, energy-intensive, and often introduce unwanted noise into audio systems.

Despite this, many enthusiasts employ them to upsample classic PCM encoding into high-rate DSD. SuperHUB’s ultra-efficient, FPGA-based audio engine executes powerful upsampling, rendering the need for a cumbersome computer in your setup obsolete.

Chasis

With such special hardware, we had to push de envelope for a matching case, so we designed a chassis from a solid block of aluminium, precision machined to house our components. The result is a blend of beauty and functionality, ensuring high structural integrity, adequate cooling and vibration resistance in a package that minimises seams and joints. Before anodization, the case undergoes a sandblasting treatment that results in a smooth surface a matte look that elegantly compliments your audio setup.

Digital Phase Locked Loop

A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize, modulate, demodulate, filter or recover a signal from a “noisy” communications channel where data has been interrupted.

Control: Effortless navigation through the IPS capacitive touchscreen, complemented by user-friendly Android and iOS control apps.

High Performance FPGA Audio

At the heart of the SuperHUB lies an AMD ZYNQ 7th generation SoC (system-on-chip) integrating hardware and software operations within a single chip. While the countless hours of concealed development efforts may remain unseen, the result is unmistakable – a fluid and continuous stream of music that bestows enduring audio delight.

In contrast to competitors, who predominantly rely on streaming products built around Rpi or off-the-shelf hardware modules, SuperHUB is constructed from the ground up on an exclusive Audiobyte hardware platform. To achieve the best possible results, we designed and built a new mainboard from scratch with a 10-layer custom PCB that allowed our engineers to optimize the signal path. Together with a linear power supply, this guarantees a seamless synergy between audio and CPU hardware, culminating in an exceptional audio experience.
