You may know, though thousands of digital audio-related data, that it is imperative that digital audio devices require clock signals. The digital audio devices express very delicate audio signals using a digital data comprised of ‘0’ and ‘1’, 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 unhappily 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 at a digital domain, but at an analogue domain such that the digital audio may be called a part of analogue audio domain, and a method capable of more easily and more clearly understanding and feeling the accuracy of the clock is to experience through sCLK-EX, which is a clock module of SOtM. If you have ever experienced at least once the sound change in audio system applied with the sCLK clock module, there will be no need of further deliberate explanation of what result can be obtained when the sCLK-EX  clock module is used that is upgraded by one step in terms of function and audio quality. The sCLK-EX can be used for all digital devices that require clock signals such as DAC, USB host card, CD player, PC main board and 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 rubidium clock by using the Master clock option. You can easily reach to the completely new sound stage by 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.Key Feature Custom designed ultra low phase noise oscillation circuit Isolated differential clock signal distribution Quad clock systems Wide operating voltage input range Ultra low noise regulator circuit External master clock input Clock control input External master clock input
