MATRIX X-SPDIF 3 USB

The new X-SPDIF3 USB digital audio interface allows your computer, tablet, or mobile phone to easily output high-quality digital audio signals to peripheral digital audio devices, transmitting in USB asynchronous mode, and converting the interface from USB input to Optical/Coaxial/AES/IIS-LVDS output. Compared to the previous generation, the IIS-LVDS output isolation has been added, completely isolating the digital output from the USB ground wire, eliminating the annoying noise from the USB front end. Additionally, it supports PCM signals up to 32Bit/768kHz and DSD signals up to 1Bit/DSD512 output, achieving excellent output quality from both PC and mobile devices.

X-SPDIF3 converts audio data to S/PDIF or IIS-LVDS signals from the USB connection, and is defined as a "problem eliminator" for digital signals. When your computer, mobile phone, or tablet does not have a coaxial or optical fiber interface, you can use the X-SPDIF3 for interface conversion, allowing your existing mobile devices to output high-quality digital audio signals to DACs. During this process, the audio signal will be optimized and transformed, and the "impurity" from the front-end device will be isolated, providing a pure and perfect digital audio signal to the back-end equipment, effectively improving sound quality. It works for 44.1kHz and 48kHz and their respective sampling rate multiples, and the FPGA automatically performs frequency division and switching control, powered by an independent ultra-low noise LDO. The clean power supply allows you to enjoy music without worries.

Both bus power from the USB connection and external power supply are available for the X-SPDIF3, with a dedicated LED indicating the power status. When connecting devices with weak power supply capabilities, such as mobile phones and tablets, you can add an external power supply to drive the X-SPDIF3 to work stably. The USB bus power will be cut off when an external power supply is connected.
