With outstanding performance, it breathes new life into your audio system, unlocking a new realm of sound quality enhancement. At its core is a 10.000 MHz ultra-low phase noise OCXO module, delivering better than -118 dBc\/Hz phase noise at 1 Hz and 20 fs jitter at the output port.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003ePrecision OCXO at the core\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eAt the core of the SC-1 lies Matrix Audio's custom-made OCXO (Oven-Controlled Crystal Oscillator) module, utilizing an SC-cut crystal. Although this cutting process is highly complex, it enables the clock module with superior phase noise and aging characteristics. With precise temperature control by the oven chamber, the crystal operates in a highly stable environment, effectively minimizing the impact of ambient temperature fluctuations on phase noise and jitter.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFour independent buffers\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe SC-1 is equipped with four independent buffered clock outputs, all derived from the same source. While ensuring synchronized output, each output is equipped with its own buffering circuit, providing not only stable output impedance but also excellent driving capabilities. Whether using a single output or multiple outputs simultaneously, it delivers precise and stable performance, meeting your diverse requirements.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003e-118dBc ultra-low phase noise\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eFor a clock source device, the output noise is closely related to the internal OCXO clock module. However, the actual output noise is not exactly the same as the OCXO output noise, as the output buffering circuit introduces some performance loss. Therefore, phase noise at the output port of the device provides more practical reference value. With the excellent design of SC-1, it achieves ultra-low phase noise of better than -118dBc at 1Hz frequency at the clock output ports, delivering purer, more stable clock signals.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eClear status indication\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe SC-1 front panel features a warm-up status indicator LED. When the oven chamber is warming up, the indicator blinks. Once the warm-up is complete, the indicator stays on. This simple and intuitive design allows you to instantly know the operating status of the device.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eCustomizable output waveforms\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eWe offer two output waveform options: sine wave and square wave, catering to diverse device requirements or your demands. Square wave output is particularly recommended, as it provides higher locking accuracy compared to sine wave, delivering a more precise clock signal.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eConstant performance\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eEven with the precise clock system of the SC-1, slight drift or deviation over time is inevitable. To address this condition, we designed a 1PPS reference signal input terminal on the rear panel. When connected to an external second-based reference signal source, the device automatically performs calibration. The calibration status will be indicated by the LED on the front panel. We also offer free calibration services to ensure your device remains accurate.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eCBVB vibration absorption system\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eEquipped with Matrix Audio’s CBVB vibration absorption foot pads, the SC-1 effectively isolates external vibrations, minimizing interference and ensuring the clock remains in a stable operating state.

It is equipped with sensitive voltage detection capabilities, enabling precise transformer winding switching based on the input voltage. Overvoltage and undervoltage protection functions are always on standby, providing comprehensive protection for stable device operation. Dual multi-stage regulator supplies independently power the oven control circuit and the clock circuit, effectively eliminating any interference from oven chamber power fluctuations on the clock circuit.
