sCLK-EX

 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.

FAQ

Can you customize the clock for my request?

Yes, it is possible to customize the sCLK-EX by your request. To do this,  you should give SOtM or the store  where you will purchase the correct information about the clock which you would like to replace to sCLK-EX.

To do this, high technical information should be required to check about the correct frequency, type of component, required voltage and other specifications and details to change your current clock system to sCLK-EX. If you are not proficient in such information or doing the process, please ask SOtM or the store from where you will purchase to do it. Otherwise, we highly recommend using the sCLK-EX combo packages such as ‘tX-USBexp + sCLK-EX48, tX-USBhubIN + sCLK-EX12, tX-USBexp + specific maind board + sCLK-EXXXXXX, etc)

And if you ask the customization of the sCLK-EX or your main board to SOtM or the store where you will purchase, some labor charge and  a round trip shipping fare should be required. 

 If the main board doesn’t work normally after the customization, SOtM or the store will take care of 50% of the repair cost .

how sound effects by internal power cables?

You can choose the wire between stranded UPOCC copper or stranded UPOCC silver, and the length choice could be made among 30cm, 50cnm or 100cm.

Normally the copper wire sounds relatively calm and neat, and the silver wire is relatively open and more delicate. 

  • 7N UPOCC Copper cable : it brings a very clean sound without having any distortion in sound.
  • Stranded 7N UPOCC standard Copper cable : it brings a clean sound with much musical nuance without having any distortion.
  • Stranded 7N UPOCC silver cable :Compared with copper wires, it brings more detailed and dynamic scenes, and brings the distinctive bright and precise sound propensity of silver wires.
  • Stranded 7N UPOCC Copper cable :Compared with the standard copper wire and silver wire, the sound character is middle of their propensities, it bring very detailed musical nuance.

Depending on which type of cable is used, it effects sound in your system hugely, so select the proper cable type for your system according to your sound taste.

The standard power cable which is supplied as a basic accessory is stranded UPOCC copper wire.
