sCLK-EX Clock Board

  • Sale
  • Regular price $700.00


The new clock board is available to output 4 points, so it could be connected to M/B, Lan port, tX-USBexp or tX-USBhubIN and another point at the same time by “a single sCLK-EX board”. The performance and features have been very much upgraded and improved than the current clock, so it will be a worthy challenge and news for all computer audiophile users.

Also the sCLK-EX can be synchronized to the external clock, so it can be synchronized with Rubidium or Reference clock.

Key Feature

Ultra low phase noise custom design oscillation circuit

Dual clock system for dX-USB HD, iM-USB HD, sMS-1000SQ and etc : Clock select input

Single clock system for tX-USBexp, tX-USBhub and etc

Wide operating voltage input range

Ultra low noise +5V output for system operation : 0.5A max
