The Matrix Audio SC-1 Reference Clock (Open Box) is a 10MHz master clock source built around an oven-controlled crystal oscillator to synchronise digital audio components. By aligning digital-to-analogue converters, CD transports, and network players to an external timing reference, the unit minimises phase jitter during conversion. The result is sharper transient detail, precise stereo imaging, and a more natural acoustic stage. As a preowned open-box unit in full working condition, this device features only minor cosmetic marks on its top aluminum casing while delivering pristine factory-spec audio performance.Oven-Controlled Crystal Oscillator:At the foundation of the Matrix Audio SC-1 is a custom oven-controlled crystal oscillator (OCXO) utilising an SC-cut crystal. Encased within an insulated, temperature-regulated chamber, the crystal remains shielded from ambient temperature shifts. This stable thermal environment ensures low phase noise, maintaining better than -118dBc/Hz at a 1Hz offset directly at the output connectors for clean timing accuracy.Isolated Multi-Device Distribution:The unit provides four independent 10MHz outputs driven by individual buffer stages to supply multiple digital components from a single master reference. Each output maintains a consistent 50-ohm impedance without cross-channel loading. An integrated linear power supply featuring automatic mains voltage detection provides filtered, isolated direct current, while a rear 1PPS calibration terminal supports reference realignment.Authorized Dealer:We are an authorized dealer for Matrix Audio.
