The Matrix Audio SC-1 Reference Clock delivers precision timing signals through four independent 50-ohm BNC outputs to unify your entire digital music playback chain. By serving as the master synchronisation hub for compatible digital-to-analogue converters, CD transports, and network players, the unit locks your digital equipment into a unified rhythm to bring greater focus, natural instrument separation, and effortless clarity to your favourite recordings.Master Timing Architecture:At the heart of the Matrix Audio SC-1 is a custom oven-controlled crystal oscillator utilising an SC-cut quartz crystal. The internal crystal rests inside a temperature-regulated chamber that shields the delicate quartz element from surrounding room temperatures. By preserving a stable thermal climate, the clock achieves exceptionally low phase noise and steady frequency delivery, allowing your soundstage to open up with sharper imaging and authentic musical texture.Multi-Component Distribution:To power multiple high-fidelity components at the same time, the clock provides four isolated outputs driven by a central reference oscillator. Each individual port features dedicated buffer circuitry that maintains uniform 50-ohm impedance and clean signal transfer across every connection. This isolated distribution prevents connected network players and DACs from interfering with one another, ensuring each piece of equipment receives an uncorrupted timing signal.Isolated Power Design:Electrical noise can quickly degrade subtle timing accuracy, so the internal architecture utilises an advanced linear power supply with separate regulation pathways. Independent voltage regulators keep power to the heating chamber isolated from the sensitive clock generation electronics, preventing heating current draws from affecting audio performance. Additionally, the unit is built in a ventilated aluminum chassis supported by vibration-damping foot pads to guard against airborne and surface vibrations.Authorized Dealer:We are an authorized dealer for Matrix Audio, giving you dedicated access to experienced technical advice whenever you need guidance with your setup. Purchasing from an authorized dealer ensures you receive complete protection with the full manufacturer's warranty and lifelong enjoyment of your music collection.
