Reaching A Higher Level

The X-SPDIF 3 USB digital audio interface from Matrix Audio 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 convert from a USB audio input to an Optical, Coaxial, AES or IIS-LVDS output interface.

Upgraded from the previous generation, the IIS-LVDS output is now fully isolated, 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 computer and mobile devices.

Filter Out The Noise

X-SPDIF 3 converts audio data to S/PDIF or IIS-LVDS signals from a USB connection, which can be called a "problem eliminator" for digital signals.

When your computer, mobile phone, or tablet does not have a coaxial or optical fibre interface, you can use the X-SPDIF 3 for interface conversion, to let your existing devices output high-quality digital audio signals to your desired DAC.

During this process, the audio signal will be optimised 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 a set of dip-switches on the bottom of the unit, to match various back-end devices. This enables the X-SPDIF 3 to suit a wider range of applications.

External Power Supply

Both the bus power from a USB connection and external power supply are available for X-SPDIF 3, with a dedicated LED indicating 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-SPDIF 3. The USB bus power will be cut off when an external power supply is connected.

CNC Aluminium Chassis

In order to achieve better electromagnetic shielding performance and reduce the effects of mechanical vibration, the X-SPDIF 3 follows the classic design of Matrix Audio, using an aluminium CNC chassis, carefully crafting every corner, showing the charm of industrial aesthetics.
