SC-1 Reference Clock

The new Reference SC-1 is Matrix Audio's first clock source and is meticulously designed for the streamers, DACs and CD players with synchronized reference clock inputs. With outstanding performance, it breathes new life into your audio system, unlocking a new realm of sound quality enhancement.

At 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.

The 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.

For 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, setting a new industry-leading standard and delivering purer, more stable clock signals.

Even 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. What’s more, we offer free calibration services to ensure your device remains accurate.

SC-1 features an advanced linear power supply with automatic voltage detection. It is equipped with sensitive voltage detection capabilities, enabling precise transformer winding switching based on the input voltage. Additionally, overvoltage and undervoltage protection functions are always on standby, providing comprehensive protection for stable device operation. Notably, 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. This exceptional design ensures superior clock signal quality from every aspect.
