SOtM sCLK-OCX10ultra

Precision at the Heart of Digital Audio

In a digital audio system, the clock is a critical element, the very heart of the system, determining the precise timing of every digital device.

As clock purity improves, sound becomes more precise, while accurate synchronization between devices becomes the key to unlocking the full potential of the entire system.

The SOtM sCLK-OCX10ultra is a next-generation high-end Master Clock Generator that takes the technology of the acclaimed sCLK-OCX10 to an entirely new level.

Ultra-Precise 10MHz Master Clock

Built upon ultra-precision oscillator technology and SOtM’s refined circuit design, the sCLK-OCX10ultra provides an exceptionally stable and clean reference clock.

By supplying the same 10MHz reference clock to network players, digital sources, DACs and other compatible digital audio devices, it allows the entire system to operate from a single, highly precise timing reference.

10 Independent Isolated Clock Outputs

With 10 independent isolated BNC outputs, the sCLK-OCX10ultra can synchronize an entire digital audio system from a single master clock, eliminating the need for multiple clock generators even in complex high-end systems.

Each clock output incorporates an independent isolation design, helping minimize unwanted electrical interaction and interference between connected components when multiple devices are synchronized simultaneously.

Extremely Low Phase Noise

Phase noise is one of the most important factors determining the performance of a master clock.

Through oscillator technology evolved from its predecessor, the sCLK-OCX10ultra achieves approximately
5dB lower phase noise in the critical low-frequency region around 10Hz, further improving timing precision and overall clock performance.

The internal oscillator achieves phase-noise performance down to -170dB/Hz, together with outstanding temperature stability of ±5ppb.

Pure 10MHz Analog Sine-Wave Output

Unlike conventional clock products that generate digital square-wave signals, the sCLK-OCX10ultra utilizes SOtM’s proprietary analog circuit technology to produce a
pure 10MHz analog sine-wave clock signal with extremely low noise.

This approach goes beyond simple sound tuning. By refining the clock signal itself, the foundation of digital audio timing, SOtM aims to achieve a more natural, delicate and sophisticated musical presentation.

Greater Space, Detail and Musical Density

With ultra-precise clock synchronization, a digital audio system can deliver a more stable soundstage, a more natural sense of space and greater refinement in musical detail.

The sCLK-OCX10ultra is designed to preserve subtle musical information across the entire frequency range while vividly conveying the dynamic energy and individual character of instruments.

In particular, the mid and low frequencies gain greater weight, texture and musical density, creating the kind of natural and immersive presentation traditionally associated with high-end analog sources such as reel-to-reel tape machines and turntables.

Beyond simply reproducing sound, the sCLK-OCX10ultra reveals subtle nuances, spatial depth, instrumental energy and the emotion contained within the recording, helping create a more complete and immersive musical experience.

Experience a new level of digital audio with the SOtM sCLK-OCX10ultra.
