Matrix Audio X-SPDIF 3 Interface Converter

Reach Higher Level

The new X-SPDIF3 USB digital audio interface allows your computer, tablet or mobile phone to easily output high-quality digital audio signal to peripheral digital audio devices, transmit in USB asynchronous mode, and achieve from USB input to Optical/Coaxial/AES/IIS-LVDS output interface conversion.

Compared with the previous generation, the IIS-LVDS output isolation is added, which completely isolates the digital output from the ground wire of the USB end, and bids farewell to the annoying noise of the USB front end. In addition, it supports up to 32Bit/768kHz PCM signal and 1Bit/DSD512 signal output, achieving an excellent output quality from both PC and mobile devices.

Filter the noise of digital audio signal
X-SPDIF3 converts audio data to S/PDIF or IIS-LVDS signals from USB connection, which can be called a "problem eliminater" 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, to let your existing mobile devices output high-quality digital audio signals to the DACs, During this process, the audio signal will be optimized and reformed, and the "impurity" from the front-end device will be isolated, providing perfect and pure digital audio signal to the back-end equipment, effectively improving the sound quality.

Femtosecond Clock
With 2 femtosecond clocks from Accusilicon as the reference clock source to accurately restore the nature of music. Working for 44.1kHz and 48kHz and their multiples of sampling rate respectively, the FPGA automatically performs frequency division and switching control, it is powered by an independent ultra-low noise LDO. The clean power supply allows you to enjoy music without worries.

IIS-LVDS Definition
The X-SPDIF3 can be configured to 4 kinds of IIS-LVDS interface definitions by toggling the switch on the bottom of the unit, to match various back-end devices. Enables the X-SPDIF3 has a wider range of applications.

Dual Clock Mode
With the switches on the button of the unit, the X-SPDIF3 can be configured to 2 different clock output modes, to match different back-end devices. Simply toggle the switches, the fun of Hi-Fi is at your fingertips.

Convert Audio Codes Freely
The X-SPDIF3 is equipped with a DoP conversion function, which converts DSD DoP codes to Native DSD, and output through the IIS-LVDS port directly. Easily to achieve the code conversion of DSD, and provide a new solution for the DACs that only support native DSD capabilities.

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

CNC Aluminum Chassis
In order to achieve a better electromagnetic shielding performance, reduce the effects of mechanical vibration, X-SPDIF3 follows the classic design of ?Matrix Audio?, using an aluminum CNC chassis, carefully crafting every corner, showing the charm of industrial aesthetics. Isolate the interference from peripheral devices, helping you to create a pure PC Hi-Fi audio system.
