Black Lion Audio Micro Clock MKIII Word Clock

Lock your interfaces or digital mixer to BLA's Micro Clock MkIII and hear the difference: Less jitter and clearer audio, at sample rates up to 384 kHz.

The Black Lion Audio 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 not only can sync all of your digital audio gear together, but can significantly improve the sound quality as well. It may be the most significant single upgrade you can make to your digital audio setup. Get ready to hear what you've been missing!

The Micro Clock MkIII is a significant redesign of its predecessor, the Micro Clock MkII. Core technological improvements begin with lower-jitter crystal oscillators, higher-quality galvanic transformer isolation in the signal path, dedicated output drivers with better isolation, higher-precision signal division, and 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 during the conversion process. The feature set has expanded to include an LED display with frequency readout, six BNC outputs capable of up to 384kHz, and AES, optical, and S/PDIF outputs capable of up to 192kHz.

"The best Clock for this money or for $5000 more"

Overall: 5 out of 5 stars
(see rating details)
This clock is by far the best possible upgrade one could make to their studio for under $5000, and it only costs 1/5 of that! I have heard other clocks ten times the price, that although did likewise bring an absolute and undeniable improvement, the improvement was not as drastic as with this BLA mk3, nor was it as easily affordable. This company is really doing something right and I don't know how long they've been around or how long they can keep this up, but I hope they do because their products are changing the game for small studios where every dollar must be wisely invested to maximize sonic improvements and keep us relevant in this competitive market.
