Matrix Audio SC-1 Audio Grade Reference Clock

Matrix Audio SC-1

Precision 10 MHz reference clock designed for ultra-stable timing and elevated digital audio performance.

The Matrix Audio SC-1 is a high-precision external master clock created for audiophiles who demand absolute timing accuracy in their digital playback systems. It delivers an exceptionally stable 10 MHz signal that reduces jitter and phase noise, allowing connected devices like DACs, streamers, and servers to perform at their full potential.

Built around an ultra-low phase noise oven-controlled crystal oscillator (OCXO), the Matrix Audio SC-1 provides unmatched frequency stability and timing precision. Its influence on digital sound reproduction is immediately noticeable—enhanced spatial definition, more natural transients, and improved musical flow.

The Matrix Audio SC-1 includes four independent 10 MHz clock outputs with dedicated buffers, enabling you to synchronize multiple devices without signal degradation. The SC-1 also accepts a 1PPS input for external calibration and features automatic warm-up control for consistent performance.

Every detail of the Matrix Audio SC-1 reflects reference-level design, from its linear power supply with toroidal transformer to its vibration-damped aluminum chassis. It operates silently and maintains perfect long-term stability once powered on.

Top 20 Questions About Matrix Audio SC-1

What is the Matrix Audio SC-1?
The Matrix Audio SC-1 is a high-precision 10 MHz external reference clock designed to improve timing accuracy and sound quality in digital audio systems.

How does the Matrix Audio SC-1 improve audio performance?
It reduces jitter and phase noise in connected digital components, resulting in a more coherent soundstage, greater clarity, and enhanced dynamics.

Who should consider using the Matrix Audio SC-1?
It’s intended for audiophiles using streamers, DACs, or transports equipped with 10 MHz clock inputs who want to unlock the highest possible performance.

What type of oscillator is used in the Matrix Audio SC-1?
The SC-1 uses an oven-controlled crystal oscillator (OCXO) built with an SC-cut crystal for exceptional frequency stability.

How many clock outputs does the Matrix Audio SC-1 provide?
It includes four independent 10 MHz BNC outputs, each with its own buffer to prevent crosstalk and maintain signal purity.

Can the Matrix Audio SC-1 drive multiple devices at once?
Yes. All four outputs can be used simultaneously to synchronize up to four components with consistent clock timing.

Does the Matrix Audio SC-1 accept external reference signals?
Yes. It has a 1PPS input for calibration or synchronization with an external master reference source.

What is the phase noise performance of the Matrix Audio SC-1?
It achieves -118 dBc/Hz at 1 Hz offset, -140 dBc/Hz at 10 Hz, and -150 dBc/Hz at 100 Hz, representing world-class performance.

What type of waveform does the Matrix Audio SC-1 output?
The SC-1 outputs either a sine or square wave signal, factory-configured to match the connected device requirements.

What kind of power supply is used in the Matrix Audio SC-1?
It features a fully linear power supply with a toroidal transformer and multi-stage regulation for ultra-clean DC power.

Does the Matrix Audio SC-1 need time to warm up?
Yes. Its OCXO requires a short warm-up period to reach optimal temperature stability, after which it maintains constant performance.

Will the Matrix Audio SC-1 work with any audio brand?
Yes. It’s universally compatible with any component that accepts a 10 MHz BNC external clock input.

Is the Matrix Audio SC-1 difficult to install?
No. It’s plug-and-play—just connect a high-quality 50-ohm BNC clock cable from the SC-1 to your component’s 10 MHz input.

Does the Matrix Audio SC-1 make any noise?
No. It operates silently with passive cooling and zero fan noise.

Can I use the Matrix Audio SC-1 with a network switch?
Yes. It pairs perfectly with components like the Matrix Audio SS-1 Pro that feature a 10 MHz clock input.

Does the Matrix Audio SC-1 benefit lower-cost systems?
The greatest improvements are heard in high-resolution systems, but even mid-level systems can gain audible precision and smoothness.

How long does it take the Matrix Audio SC-1 to stabilize after power-up?
Typically within 10–15 minutes as the OCXO reaches optimal thermal stability.

What materials are used in the Matrix Audio SC-1 chassis?
It’s constructed from solid aluminum alloy to minimize vibration and shield sensitive clock circuitry.

How large and heavy is the Matrix Audio SC-1?
It measures 330 mm wide, 267 mm deep, and 97 mm high, with a weight of approximately 4.4 kg.
