SINGXER SU-2 USB Digital Interface 768khz DSD1024 SPDIF AES/EBU I2S HDMI

High-performance USB digital audio interface, using the latest XMOS family and Xilinx high-performance CPLD / FPGA chip.

One pair of Accusilicon clocks (less than 90dBc @ 10Hz), extremely low jitter rate measured 0.2ps on 10Hz-1MHz band and 0.071ps on 12-80MHz band.

Master Clock 10Mhz / 50Ohm input available!

Digital input interface using a standard USB2.0 interface. Several output interfaces are available on this converter, including coaxial RCA and BNC output S / PDIF, XLR balanced outputs AES / EBU, and HDMI output IIS.


  • AUDIO-GD (Supports native DSD / DoP - All switches OFF)
  • HOLO AUDIO (Supports auto detect DSD - All switches OFF)
  • PS AUDIO (Supports DSD auto detect - All switches OFF)
  • GUSTARD (Switch 3 ON and Switch 6 ON)


  • Windows XP, 7, 8 & 10; both 32/64 bit. Drivers must be installed (Included with product)
  • Native Mac-OS 10.6 and later, Drivers detected by OS
  • Native Linux with UAC2 compliant kernel. Drivers detected by OS
  • Android OS 4.2 and above. Support OTG function.


  • The SU-2 is the first domestic and the XMOS latest xCORE - 200 series of USB digital interface. A new generation of XMOS chip, using the more advanced process technology, the performance was doubled the old one U8 chip, the processing capacity of up to 1000 MIPS.
  • Used the high-speed whole isolation design, can be isolation between PC and interface of noise interference cleanly. SU-2 adopted a preeminent circuit design, using the high- speed CPLD/FPGA digital audio signal for separate after restructuring, so as to make the signal after reforming completely unaffected by isolation chip itself shaking.
  • SU-2 internal main board adopts the technology of the uniform source synchronous clock, CPLD/FPGA internal using special algorithm of clock signal and digital audio signal phase control strictly, can ensure that the digital audio signal after isolation chip will not appear extra distortion because of the time delay and phase difference.
  • One pair of Accusilicon clocks. extremely -ow phase noise crystal oscillator (less than 90dBc @ 10Hz) is intended for professional recording equipment as well as audiophile electronics. These models offer a remarkably low jitter rate measured 0.2ps on 10Hz-1MHz band and 0.071ps on 12-80MHz band.
  • It is well known that the weight of the core of the digital audio is algorithm. Singxer team are occupied in the field of digital audio for many years, at the same time we get strong support from the XMOS FAE team, we are on the basis of the original firmware had done. Many of the technical improvement and optimization algorithm.
