About the SU-6
The Singxer SU-6 is a USB-to-digital audio interface (digital-to-digital converter), not a DAC: it takes audio from a computer or other USB host and outputs digital signals for an external DAC. It uses an XMOS xCORE-200-series USB processor and FPGA-based processing, with femtosecond clocking and a supercapacitor-based power arrangement. Its range of outputs includes S/PDIF, AES/EBU, I²S, and clock signals. availability may vary by region.
