Precision in Time

The more sophisticated a Hi-Fi digital audio system becomes, the more it relies on a stable timing reference. Engineered for exceptional stability and accuracy, the Eversolo C10 High-Precision Master Clock provides a reliable timing reference for high-performance HiFi systems. By minimizing timing errors, C10 helps preserve the integrity of the audio signal, bringing greater clarity, a more expansive soundstage, and a natural sense of musical coherence.

The Core of Stable Timing

How a crystal is cut defines how stable it remains through temperature changes, internal stress, and years of operation. The custom OCXO developed for C10 uses an SC-cut crystal. Its sophisticated, doubly rotated geometry makes the crystal less susceptible to temperature variation and internal stress. More demanding to manufacture, it provides a stronger foundation for frequency stability while supporting lower phase noise and improved long-term aging performance.

Precision oven control keeps the crystal at a stable operating temperature, minimizing the effects of environmental change on clock performance. Precision, held steady through every synchronization.

Every Clock Aligned

Combining an SC-cut quartz crystal with precision temperature control and a low-noise oscillator design, C10’s high-stability OCXO suppresses temperature-induced frequency drift, establishing a stable, clean 10 MHz reference.

The C10 features a high-precision PLL with a high-quality internal oscillator and precision feedback control to maintain accurate frequency and phase synchronization. Engineered to exacting standards, it provides stable, reliable timing for the entire system.

Eversolo’s proprietary Reference Timing Engine (RTE) turns the stable 10 MHz reference into system-wide timing order. Working with 1PPS external time synchronization, it brings the entire system onto a shared time scale.

Additional Features

1PPS Reference Timing
Even precision clocks can drift over time. With its GNSS 1PPS reference input, C10 uses the 1PPS timing pulse provided by global navigation satellite systems as a long-term reference, automatically recalibrating its internal time base to maintain accurate timing, second by second.

One Source, Four Outputs
C10 features four BNC clock outputs, all driven by the same high-precision clock source, giving multiple digital audio devices a unified reference for synchronization. Each output has its own dedicated buffer circuit to help isolate load changes and interference. Use one output or several at once, with stable, consistent clocking for streamers, DACs, and CD transports.

Stable Power
The C10’s toroidal transformer minimizes magnetic leakage and power-line noise, delivering clean, stable power to the clock module and control circuitry.

Flagship Source System
The C10 Master Clock can connect to streamers, CD transports, DACs, and other components with external clock inputs, bringing precise timing to an existing HiFi system.
