Improvements Include Dedicated Output Drivers, Heavier Noise Filtration
Image placeholder title

Unparalleled accuracy that not only can be measured, but heard

Black Lion Audio, an independently owned company based in Chicago, today announced the release of the Micro Clock MkIII, a significant redesign of its predecessor, the Micro Clock MkII.

The Micro Clock MkIII is the culmination of almost 10 years of research involving jitter-reducing, harmonic-enhancing design techniques not found in any other master word clocks on the market. It's the easiest way to upgrade your existing digital audio setup, whether it's for live, studio, or home use.

Core technological improvements include:

  • Lower-jitter crystal oscillators
  • Higher-quality galvanic transformer isolation in the signal path
  • Dedicated output drivers with better isolation
  • Higher-precision signal division
  • Much heavier noise filtration throughout the circuit.

All of this results in a more robust, lower-jitter clock signal than the Micro Clock MkII, with even more desirable harmonics in the clock’s spectral band that impart an undeniable musical quality to the conversion process. The feature set has expanded to include an LED frequency display, six BNC outputs capable of up to 384kHz, AES and RCA S/PDIF outputs capable of up to 192kHz, and an optical S/PDIF output capable of up to 96kHz.

"I’ve never been one who believes a particular clock is going to significantly change my world" says multi-Grammy Award winning producer/engineer Tony Maserati (Beyonce, Jason Mraz, Black Eyed Peas). "I’ve used some of the best names, and it’s comforting to know they all perform within a few degrees of one another, which is why I wasn’t dying to try a new one.

When Black Lion Audio sent me the Micro Clock MkIII, I waited till I had a room full of engineers and producers before plugging it in. In blind testing, the team chose the Micro Clock MkIII over our previous clock. I sat skeptical in the rear of the room. When I finally ventured to the sweet spot and A/B’d it for myself, it was clear. Black Lion Audio had surprised me. The Micro Clock MkIII produced a better depth of field and increased clarity.

In the world of mixing records, I’ll implement any gear into my system that brings my mixes closer to an approved master, faster. The mixes I’ve been doing with the Micro Clock MkIII have gotten better responses from my clients and make the decision-making process easier for me."
