About the sCLK-OCX10

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 -- the higher purity of clock, the more accurate and better the sound quality.

The sCLK-OCX10 is specially designed for high-end audio equipment, bringing all the benefit of a master clock that is normally used in recording studios and high performance audio. It can be used with devices equipped with a BNC connector for a master clock input.

For SOtM products, the 10MHz master clock input connector can be added to SOtM products with an internal sCLK-EX clock (such as sMS-1000SQ, sMS-200ultra and tX-USBultra).

As many audiophiles know, a clock signal is an angled square digital signal, but the sCLK-OCX10 produces a pure analog sine wave of 10MHz. This sinusoidal clock signal is the method adopted for the best clock products because it generates much less noise than the angled square digital clock signal. The sCLK-OCX10 consists only of an analog circuit which contains 10 years of SOtM's experience. It derives high analog sound that is different from other master clocks on the market which output angled square digital clock signal.

The sCLK-OCX10 produces very delicate, smooth and natural sound especially in the mid- to low bandwidths. It brings very clear and significant improvement expected with the best analog devices -- so with the sCLK-OCX10, you can experience not only music played by a system, but the essence, artistry and heart of the music. 

The sCLK-OCX10 has four outputs, which can be used simultaneously with 4 BNC connectors for master clock input device. Output impedance can be set to 50 ohms or 75 ohms.

The resolution, textures, transparency and expression of sound is greatly affected by how and what power is supplied to your audio device. A power supply unit affects the quality of the entire audio system, and should never be considered as “just a power supply unit.”

The sPS-500 is an audio power supply designed specifically for high performance audio. It is built to eliminate noise generated by powered devices as well as to simply remove noise coming from an AC power source.

Using SOtM's unique technologies for noise cancellation and sound enhancement, and high quality audio components that are already proven in sound quality, you will hear superior sound improvement with the well-designed sPS-500.

The sPS-500 can easily cope with a wide range of AC power input – the output voltage can change to 7Vdc, 9Vdc, 12Vdc or 19Vdc depending on the power specification of your audio equipment – and the 50W output is flexible enough to be applied to various audio systems. It is also designed to provide more stable power through the input, output, overcurrent and overheat protection circuits.

The rich texture and detailed, luxurious sound created with the technology of the new sPS-500 will create a new listening experience with your audio system. A unique and impressive exterior design also makes the sPS-500 stand out from the crowd. The sPS-500 will help bring your audio system up to the next level.
