Know before you buy
The sCLK-EX replaces standard, lower-quality clocks in your digital audio components with an ultra-low phase noise circuit. This reduces jitter and timing errors, resulting in a more precise, stable, and detailed sound reproduction.
Yes, the sCLK-EX supports up to four simultaneous clock outputs. This allows you to synchronize multiple compatible devices, such as your motherboard, LAN port, and USB expansion cards, to a single, high-precision timing source.
Yes, the board features an isolated external master clock input. This allows you to bypass the internal reference clock and sync the system with high-end external master clocks, such as Rubidium or Reference units, for even greater accuracy.
The board is designed to integrate with specific SOtM hardware, including the dX-USB HD, iM-USB HD, sMS-1000SQ, tX-USBexp, and tX-USBhubIN. Please ensure your specific model is listed as compatible before installation.
Yes, the board requires an external power adapter. It typically operates on 9Vdc, though it can also be configured for 12Vdc or a range between 6.5Vdc and 8.5Vdc depending on your specific setup requirements.
Isolated signal distribution prevents electrical noise from traveling between the clock and your connected components. By keeping these signals clean and separated, the board ensures that the timing precision remains unaffected by interference from other parts of your system.
