Revolution Clock

Black Lion Audio Revolution Clock
The Black Lion Audio Revolution Clock is a portable word clock designed to keep every digital audio device in your studio running in perfect synchronization. Supporting connections over BNC, S/PDIF, optical, and AES/EBU, it is built to serve studios of virtually any size and configuration, capable of clocking up to seven devices simultaneously, four of them over BNC. Whether you are tracking a simple two-piece session or an elaborate multi-device production, the Revolution Clock is engineered to deliver the timing accuracy your music deserves.

Rock-Solid Sync Across Your Entire Digital Rig
The Revolution Clock delivers rock-solid clocking to keep all of your digital audio devices running in perfect sync, with support for sample rates ranging from 44.1kHz all the way up to 384kHz over BNC. At the heart of its performance is an impressively low jitter figure of just 0.5 picoseconds RMS at the BNC outputs, ensuring that every device in the chain operates with maximum timing precision. Once a system is properly clocked, many users observe a greater sense of space and depth in their mixes, thanks to more accurately reproduced reverbs and stereo imaging — and some even discover elements of their productions they had not previously heard at all.
Why Clocking Matters in Multi-Device Studios
When running multiple digital audio devices simultaneously without clock sync, clocking jitter can result in smearing of the stereo field, and this is particularly noticeable in transients and higher-frequency material like cymbals and lengthy reverb tails. Crucially, the effects of poor clocking are cumulative — noise and jitter may be difficult to detect on a simple two-track recording, but across a complex 64-track production, those issues begin to stack up in ways that can meaningfully degrade the final result. Superior clocking through a dedicated word clock like the Revolution Clock addresses these problems at the source, preserving the integrity of every signal passing through your studio.
Advanced Technology: MEMS Oscillators and Patented Macro-MMC
The Revolution Clock employs MEMS (Microelectromechanical systems) oscillators, which outperformed traditional quartz crystal oscillators in both subjective listening tests and objective stability measurements. MEMS oscillators require no thermal solution for stability, as their performance is less affected by temperature fluctuations, and they also offer greater shock resistance than quartz crystals — making them especially well-suited to portable and touring environments. Complementing this is Black Lion Audio's patented Macro-MMC technology, a proprietary clocking system developed through years of experience building dedicated word clocks and performing interface modification services. Macro-MMC ensures low noise and minimal jitter through strict component selection and proprietary methods of signal propagation, carrying a high-quality oscillator signal with full accuracy and integrity all the way to the unit's outputs.
Why We Love This
Our Gear Experts appreciate the Revolution Clock because it transforms the way their productions sound and feel. By eliminating the jitter that smears stereo imaging and muddies transients, it unlocks a greater sense of space and depth that was always in the recording but never fully audible. For producers working with large track counts, the benefits are especially dramatic — jitter and noise stack up fast, and the Revolution Clock keeps all of it at bay, letting the music breathe exactly as intended.
