What customers say
Audiophiles consistently describe the SOtM sCLK-OCX10 as a transformative upgrade, focusing primarily on enhanced timing and precision. Users report that connected digital components achieve significantly more coherent, dynamic, and natural sound. Key benefits include an expanded soundstage with superior image specificity and substantially improved detail retrieval, creating an almost analog fluidity. While the premium price positions this as a high-end investment, owners feel the performance gains justify the cost for reference level systems. The meticulous engineering and robust build quality further solidify its reputation as an essential component for state of the art digital audio.
Know before you buy
The sCLK-OCX10 acts as a high-precision master clock generator that provides a stable 10 MHz reference signal to your digital audio components. By synchronizing your devices to this high-purity signal, it reduces jitter and improves the overall timing accuracy of your digital-to-analog conversion.
No, the sCLK-OCX10 does not include a power adapter. You will need to provide a 12Vdc power source to operate the unit.
Yes, the unit features four isolated BNC outputs, allowing you to connect up to four compatible audio components at the same time.
Your audio equipment must have a dedicated 10 MHz master clock input, typically labeled as 'Word Clock' or 'External Clock' input. Please verify that your device supports a 10 MHz sine wave signal before connecting.
The output impedance is configurable. While the standard unit uses 50-ohm BNC connectors, there is an option to select 75-ohm impedance to ensure proper matching with your specific audio components.
The analog sine wave output is designed to minimize high-frequency noise and interference. This approach helps deliver a smoother, more natural sound profile compared to the sharper, more aggressive edges of a square wave signal.
