Black Lion Audio Micro Clock MKII Word Clock Generator
The Black Lion Audio Micro Clock MKII Word Clock Generator is a simple, yet elegant design in external clocking. It features ultra-low jitter, third order crystal oscillators with a high current parallel drive circuit designed to maintain harmonic content of the signal regardless of loading conditions. In addition to this, proprietary noise reduction circuitry dramatically eliminates unwanted switching harmonics normally found in digital signals. The Micro Clock MKII is one of the best performing external word clocks in the pro audio market today.
The Black Lion Audio Micro Clock MKII is a completely revolutionary design in external clocking from Black Lion Audio. The Micro Clock MKII is a radical departure in design from its predecessor. It features ultra-low jitter third order crystal oscillators with a revolutionary patent-pending high current parallel drive circuit designed to increase the amount of desirable harmonics within the clock's spectral band. In addition to this, the proprietary noise reduction circuitry dramatically eliminates the unwanted switching harmonics normally found in digital signals. These are musically unrelated signals that create distortion and phase cancellation within the converted audio signal. Because of these technological advances, the Micro Clock MKII may well be one of the best performing external word clocks within the pro audio market today.
The Micro Clock MKII is simple and probably even boring looking by most standards. Its housed in a rugged 3 x 4 chassis that provides optimum RF shielding. It has no lights, no frequency display, and none of the usual visual candy that your friends might envy. However, for a modest black box, it does its job incredibly well and at a price thats unheard of for this level of performance!
The Micro Clock MKII features six selectable output frequencies from 44.1 kHz on up to 192 kHz. The output level is approximately 5 volts peak to peak. Jitter at the crystal oscillator is approximately 1 picosecond RMS, and just under 10 picoseconds RMS at the output. The power supply is a 9 volt DC wall wart thats capable of accepting both 120 and 240 volts AC. The clock is compatible with all modern digital devices that have 75 ohm BNC word clock inputs.
Black Lion Audio Micro Clock MKII Word Clock Generator Features
- Output: 3 galvanic-isolated BNC with fixed 75 ohm terminations @ 6 volts peak to peak
- Power: 9-12 volts DC
- Sampling Rates: Six selectable rates, 44.1 kHz-192 kHz
- Jitter: Maximum 1 pico second of intrinsic jitter, less than 10 picoseconds of accumulated jitter measured using a delta sigma averaging method.
What We Think
We have put this little guy up against some of the best clocks out there and it regularly meets and often exceeds their performance in regards to the resulting sound quality. It's a great piece for getting up to 3 digital devices w/ BNC word clock inputs to receive clock simultaneously, but it's an even better device for making all of those devices reach their peak sonic potential. When using it with a stock Digi002r and a DigimaxFS (which has word clock I/O and I clocked the Digi002r off of the ADAT input), the resulting audio was much clearer, deeper, and wider with much more specific ability to localize placement of specific elements within the mix. I even noticed an increase in overall level due to the increased frequency response. The Micro Clock is an amazing little device that is also an incredible value. The original MicroClock, the "Mk I", put out an AC word clock signal for MOTU units, which was the only brand that Black Lion Audio was modifying at that time that the Micro Clock was first designed. While a lot of gear could still read that signal, there were several digital devices that could not sync to it. The new Black Lion Audio Micro Clock MKII puts out a DC Pulse which is what every other piece of digital gear wants to see and it's still compatible with MOTU gear.

I"m used this clock for yamaha digital consoles all types. All consoles make is bests sound. sorry for bad inglish.
a little quirky with my Aurora Lynx converter. It doesn't sync up right away - I've found that if I switch the Playback Engine buffer size a few times (Pro Tools 9), and let the track play about 30 seconds it eventually locks to sync. It seems to have resolved some digital clicks and pops I had been struggling with. But what about the sound, you ask? Well - I *think* things sound a little more open and clearer, but it is very subtle.
The box could not be simpler. It does one thing which is to send out a rocksteady clock signal. I was clocking from my Rosetta converter before and things sounded pretty good. With the addition of the BLA clock everything sounds subtly tighter and more open. A great little box!
