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, a higher purity clock brings more accurate and better sound quality. However, the higher purity clocks also requires higher costs, therefore, a high-purity 10MHz clock, like a master clock, is not installed inside of the audio device but connected to the internal clock and synchronized by a master clock as the way to improve sound quality.
The sCLK-OCX10 is a specially designed product for high end audio equipment which brings all the benefits of master clocks that have been used primarily in recording studios and high performance audio. It could be the paramount digital device for audiophiles who want the best sound quality. It can be used with devices equipped with a BNC connector for their master clock input. For SOtM products, 10MHz master clock input connectors can be optionally added to products with the sCLK-EX installed such as the sMS-1000SQ, the sMS-200ultra, and the tX-USBultra can be used with the sCLK-OCX10.
As many audiophiles know, the clock signal is an angled square digital signal, but the sCLK-OCX10 produces a pure analog sine wave of 10 MHz, and this sinusoidal clock signal is the method adopted for the best clock performance because it produces significantly less noise than the angled square digital clock signal. In order to implement this, the sCLK-OCX10 consists of only analog circuitry which contains 10 years of know-how of SOtM, it derives high analog sound that is different from other master clocks on the market which output angled square digital clock signals.
Throughout all bandwidth, the sCLK-OCX10 produces a very delicate, smooth and natural sound without losing the inherent energy that every instrument has, especially in the mid-low bandwidths. It brings very clear and significant improvement which normally can be expected by the best analog devices, so with the sCLK-OCX10, you can experience not only music played by a system, but the essence and the artistry of the music’s heart. And such experience means absolute improvement that can be only achieved through SOtM’s technology rather than tweaking sound.
The sCLK-OCX10 has four outputs, and it can be used simultaneously with 4 BNC connectors for master clock input devices. Optionally, the output impedance can be set and selectable to 50 ohms or 75 ohms.
