Matrix Audio X-SPDIF 2 Interface Converter

32Bit/768kHz DSD512 USB Interface

Onto Higher Level

The newly designed USB Audio Class 2.0 asynchronous digital interface X-SPDIF 2, inherited the excellent quality from its last generation. You can connect the digital audio stream receive devices through the newly added IIS port, to avoid the loss caused by digital signal protocol conversion. X-SPDIF 2 built-in high-quality femtosecond clock and FPGA processing unit, it can playback up to 32bit/768kHz PCM audio stream and 1bit/22.4MHz DSD audio stream.

More Powerful X-CORE

The new generation XMOS U208 is an 8 core digital signal processing unit, it has powerful multi-core and multi-threaded processing capabilities, and it is the industry's most advanced USB Class 2.0 digital audio solution by far.

FPGA Control Centre

The strong XILINX SPARTAN FPGA assist XMOS manage and assign the clock, processing DoP transcoding and JITTER reduction for IIS port.

Audiophile Crystal Oscillators

X-SPDIF 2 uses 2 Accusilicon high-quality femtosecond clocks as reference clock source, which work at the state of 44.1kHz, 48kHz and their multiple sample rate. The FPGA automatically control the frequency assignment and switching, and the femtosecond clock has independent ultra-low noise LDO power supply.

Multi-level LDO

The power supply units of X-SPDIF 2 are constructed by multi-level, multi-group LDOs and solid capacitors, they can filter out the superimposed noise from power supply effectively. All the circuit powered by low noise or ultra-low noise LDO, which avoided the hi-frequency switch noise caused by DC/DC circuit. You also can obtain high quality power from USB bus.

Configurable IIS Port

X-SPDIF 2 support different standard of IIS, it can compatible for different devices by configuring the IIS definition switch. The DoP converting function transcode DoP audio stream to native DSD stream output from IIS port.

External Power Supply Supported

X-SPDIF 2 has a power supply interface, you can add an external linear power supply to it. It will disconnect the USB bus power automatically when you connect it to an external power, then the X-SPDIF 2 can work with mobile devices.

CNC Aluminum Chassis

In order to get the best electromagnetic shielding performance, to minimize the impact of mechanical vibration, X-SPDIF 2 still followed the CNC aluminum chassis design. We are not afraid of the complicated design and process, to make sure your computer can output high quality digital audio stream.

Supported Sample Rate

PCM 16-24Bit /44.1kHz、48kHz、88.2kHz、96kHz、176.4kHz、192kHz

PCM 16-32Bit /44.1kHz、48kHz、88.2kHz、96kHz、176.4kHz、192kHz、352.8kHz、384kHz、705.6kHz、768kHz
DSD64/128/256/(DoP) DSD64/128/256/512(Native)
NOTE: Please see the X-SPDIF 2 user manual for the IIS LVDS definition.

System Support: 
Windows7/8/8.1/10 system needs to install the supplied driver.
Mac OS X10.6.4 or above without installing the driver.
Most Android devices can be used via OTG cable.
The iOS devices can be used via Lightning to USB Camera Kit.


Power Supply Specs:
USB bus power supply: 5V/500mA
External power supply: DC 6~9V,≥800mA
Power supply port: outer diameter 5.5mm; inner diameter 2.1mm (+ for inner, - for outer)
NOTE: Do not connect to the power supply with a voltage above 9V, or will cause damage.It will auto disconnect USB bus supply after connected to the external power supply. It needs to connect to the external power supply when using mobile phone or pad which USB port with low current output.

Replacement for Stello U3
Monday, 30 March 2020  | 

1. It did the job - great product for those like me who have an audio pc and need to connect it to sp dif input. My Stello was a great product and the Matrix was more than an adequate replacement.
2. The sound was different, I thought. It was more detailed ("clinical" and with more defined stereo. My test was Miles Davis Kind of Blue on CD. Cannonball Adderley's alto sax was particularly distinctive. Well pleased and would recommend to those with similar needs.
