The Allo USBridge Signature Player is based on a Raspberry Pi Compute Module 3+ SBC (Single Board Computer), offering this system great versatility. The Volumio operating system is pre-installed, and will allow you to easily access your entire audio library on a network or locally (USB storage).
The purpose of this module is to reduce noise on the USB bus as much as possible in order to provide the purest, most accurate and richest sound reproduction possible. For this purpose, the USBridge Signature includes an excellent USB control chip from TI and the Ethernet circuit is completely separate from the USB circuit, thus limiting interference. In addition, noise has been reduced on each power rail through the use of more than 30 LDO controllers. Even the power rail of the Micro SD port has its own LDO. Thus, the module does not include any switching elements that can generate noise.
As the USBridge Signature is based on a Pi Compute, Allo has chosen to integrate all the available connectivity on a standard Raspberry Pi, namely a GPIO port, USB-A, HDMI and a Micro SD slot. Therefore, anything that works with a Raspberry Pi will work with the USBridge Signature.
