Singxer-SU1 with SOtM sCLK-EX Upgrade

Regular price $1,499.00

High-performance USB digital audio interface, using the latest XMOS family and Xilinx high-performance CPLD / FPGA chip. All internal Singxer clocks are replaced by the SOtM sCLK-EX high performance clock board to achieve ultimate audio signal quality. Digital input interface using a standard USB2.0 interface. Several output interfaces are available on this converter, including coaxial a 10Mhz Master Clock input and additional clock outputs.

It works as a hub by receiving and distributing USB audio signals, but regenerating the USB AUDIO signal by the high-performance super clock module, sCLK-EX, installed inside the Singxer SU1. The mid-low range sounds very deep, detailed and earnest, the high range sounds not distract but extremely delicate and open, and especially the very low range gives you transparency you have never heard before and gets you very natural and solid texture of performance.

External Power Suppy Required (9V DC)

The standard power supply is replaced by a 9V DC INPUT (SOtM Form Factor). Can be powered by a SOtM SPS-500

FEATURES

The SU-1 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-1 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-1 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.

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.
