The sCLK-OCX10 is a master clock generator that produces a high purity 10 MHz clock signal.

In digital audio devices, the clock signal acts as the heart of the product, a higher purity clock brings more accurate and better sound quality. However, the higher purity clocks also requires higher costs, therefore, a high-purity 10MHz clock, like a master clock, is not installed inside of the audio device but connected to the internal clock and synchronized by a master clock as the way to improve sound quality.

The sCLK-OCX10 is a specially designed product for high end audio equipment which brings all the benefits of master clocks that have been used primarily in recording studios and high performance audio. It could be the paramount digital device for audiophiles who want the best sound quality. It can be used with  devices equipped with a BNC connector for their master clock input. For SOtM products, 10MHz master clock input connectors can be optionally added to products with the sCLK-EX installed such as the sMS-1000SQ, the sMS-200ultra,  and the tX-USBultra can be used with the sCLK-OCX10.
