Professional-grade clocking for the most discerning digital setups.
In a high-end digital system, timing is everything. A Master Clock serves as the heartbeat of your audio chain, ensuring that every digital component—from your streamer to your DAC—is perfectly synchronized. Our collection is headlined by MUTEC, the industry standard for ultra-low jitter clocking and signal re-generation. By providing a single, high-precision reference signal, a master clock eliminates the timing errors (jitter) that can smear the soundstage and veil fine detail. Whether you are looking to refine a professional studio setup or achieve the absolute pinnacle of home audio transparency, these units provide the ultimate foundation for digital clarity.

The Final Frontier of Digital Audio.
Upgrading your streamer or DAC is usually the first step in digital audio, but introducing a dedicated Master Clock is the ultimate endgame. Think of a digital audio signal like a live symphony orchestra. If the musicians (the 1s and 0s) are world-class, but the conductor (the internal clock) has a slightly unsteady hand, the performance feels blurred and fatiguing. A Master Clock replaces that unsteady hand with a robotic, atomic-level precision. Click through the tabs below to understand how digital timing works and why brands like MUTEC are the secret weapon in reference hi-fi systems.
The Enemy (Understanding Jitter)
When digital data travels from your streamer/transport into your DAC, it rides on a square wave frequency. If the timing of that wave fluctuates even by picoseconds (trillionths of a second), the DAC converts the audio at slightly the wrong moment.
- The Smearing Effect: This timing error is called Jitter. It doesn't cause pops or clicks; instead, it smears the high frequencies, muddies the bass, and flattens the 3D soundstage. It is the primary reason why digital audio can sometimes sound fatiguing, harsh, or "clinical" compared to the smooth, organic nature of a vinyl record.
- Phase Noise: Premium clock manufacturers focus heavily on reducing "phase noise" (the random fluctuations in the clock signal itself). The lower the phase noise, the cleaner the square wave, and the more accurately your DAC can reconstruct the original analogue waveform.
Re-Clockers vs. Reference Clocks
Depending on the connections available on your current DAC or Streamer, there are two distinct ways to upgrade your digital timing.
- Inline Re-Clockers: Devices like the legendary MUTEC MC3+ USB sit between your streamer and your DAC. You run your digital audio into the MUTEC, it scrubs the signal entirely, completely rebuilds the data using its own ultra-precise internal clock, and sends a mathematically perfect, jitter-free signal out to your DAC. This is brilliant for DACs that do not have dedicated clock inputs.
- 10MHz Reference Clocks: The absolute pinnacle (such as the MUTEC REF10). This device does not process music data at all. It is a pure, ultra-stable 10MHz oscillator. You connect it directly to the dedicated "10MHz Clock Input" on a compatible high-end DAC, Streamer, or Re-Clocker. It acts as the ultimate "heartbeat," forcing all your digital components to march to the exact same, flawless rhythm.
The MUTEC Advantage
When discussing master clocks, MUTEC is a foundational pillar. Designed and manufactured in Berlin, their equipment is trusted by the world’s most prestigious mastering studios and discerning audiophiles alike.
- Ultra-Low Phase Noise: While many brands boast about atomic Rubidium clocks, MUTEC focuses on what actually matters for audio: phase noise. Their proprietary, oven-controlled oscillators (OCXOs) are engineered to deliver the lowest possible phase noise in the critical audio band, vastly outperforming standard atomic clocks when it comes to musicality.
- Galvanic Isolation: MUTEC devices employ extreme internal shielding and galvanic isolation to ensure that the noisy electrical interference from a computer or streamer cannot travel down the cable and infect your delicate DAC circuitry.
Master Clocks FAQs
Does my DAC need a special input to use a Master Clock?
Does my DAC need a special input to use a Master Clock?
It depends on the type of clock you buy. If you want to use a pure Reference Clock (like a 10MHz generator), your DAC or Streamer must have a dedicated BNC input labelled "Word Clock In" or "10MHz In".
If your DAC does not have a clock input, you can still reap the massive benefits of re-clocking by purchasing an Inline Re-Clocker (like the MUTEC MC3+). You simply run your standard digital cable (USB, Coaxial, Optical) into the re-clocker, and another digital cable out of the re-clocker into your DAC.
Can a Re-Clocker fix the terrible audio coming from my standard PC or Mac?
Can a Re-Clocker fix the terrible audio coming from my standard PC or Mac?
Absolutely. This is one of their greatest use cases. Standard computers have horrific internal timing and massive amounts of electrical noise (EMI/RFI). By running a USB cable from your computer into a premium re-clocker, the device will galvanically isolate the signal (blocking the electrical noise) and completely rebuild the timing of the audio stream before handing it off to your DAC. It turns a standard, noisy PC into a world-class digital transport.
What is an OCXO, and why do high-end clocks use them?
What is an OCXO, and why do high-end clocks use them?
OCXO stands for Oven-Controlled Crystal Oscillator. Temperature changes in a room will cause the crystal inside a clock to physically expand or contract, which alters its timing frequency and creates jitter. An OCXO physically encapsulates the crystal inside a miniature, electronically controlled "oven" that keeps it at a constant, exact operating temperature, ensuring microscopic timing stability regardless of the environment.
Do I need special cables to connect a Master Clock?
Do I need special cables to connect a Master Clock?
Yes, the cable is critical. Master Clocks transmit high-frequency square waves, not analogue music. You must use a dedicated, high-quality BNC Clock Cable. Furthermore, you must match the impedance. Depending on the manufacturer, clock outputs are either 50-Ohm or 75-Ohm (MUTEC often provides both). You must use a 50-Ohm cable for a 50-Ohm connection to prevent signal reflections that cause the very jitter you are trying to eliminate!
Why shouldn't I just buy a better DAC instead of adding a clock?
Why shouldn't I just buy a better DAC instead of adding a clock?
A high-end DAC is crucial, but every DAC is entirely dependent on the quality of the signal fed into it. Even a £10,000 DAC will sound compromised if it is fed a jitter-filled signal from a noisy source. By adding a dedicated Re-Clocker or Master Clock, you are ensuring your DAC is operating at 100% of its theoretical capability.
Will adding a Master Clock change the "tone" of my system?
Will adding a Master Clock change the "tone" of my system?
A master clock is not a tone control; it does not add artificial warmth or boost the bass like an equalizer. Instead, it removes distortion. By removing the jitter that artificially brightens and smears the sound, the true, natural tone of your DAC and speakers is revealed. Listeners consistently report that the bass tightens up dramatically, and the top-end becomes incredibly smooth, detailed, and fatigue-free.
