About SOtM SCLK-EX2MC
You may know, with countless digital audio-related data, that it is imperative that digital audio devices have clock signals.
The digital audio devices express very delicate audio signals using a digital data comprised of ‘0’s and ‘1’s, and although the digital audio devices can also transmit the audio signals to other devices, the digital audio signals have to be converted eventually to analogue signals to reach us because the digital data cannot be felt or understood by our senses. This process is called a Digital to Analog Conversion, and the digital data in this process is converted to an analogue signal in response to a signal (clock signal) where ‘0’ and ‘1’ are repeated at a predetermined time interval.
Theoretically, although a perfect clock signal must repeat ‘0’ and ‘1’ at a predetermined time interval, the perfect clock signal unfortunately does not exist in this world. All clock signals have a time error, and a more perfect analogue signal can be made when the number of errors grows fewer.
The time error, that is, the accuracy of clock is measured and managed not in the digital domain, but in the analogue domain such that the digital audio may be called a part of the analogue audio domain. A method to more easily and more clearly understand and feel the accuracy of the clock is to experience the sCLK-EX, which is a clock module of SOtM.
If you have ever experienced at least once the sound changes in an audio system incorporating an sCLK clock module, there will be no need for further deliberate explanation of what results can be obtained when the sCLK-EX clock module is used. It is on another level in terms of function and audio quality.
The sCLK-EX can be used for all digital devices that require clock signals such as a DAC, a USB host card, a CD player, a PC main board and a LAN controller. The sCLK-EX can simultaneously use four (4) clock outputs so that one single sCLK-EX board can be used for various frequencies including the system clock, LAN port clock and USB clock in your PC.
Furthermore, the device can be used synchronously with a high precision clock such as a rubidium clock by using the Master clock option.
You can easily reach a completely new sound stage with a single sCLK-EX board. You are requested to please experience a different dimensional world brought by sCLK-EK, which is an upgraded version approved by already advanced technology and sound.

- 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.
