Black Lion Audio Micro Clock mk2 External Word Clock

Hear audible results with Black Lion Audio's Micro Clock mk2 external word clock. No hype here; just pristine signal path and more of the harmonics you want.

The quality of your digital audio is dependent upon the quality of your digital clock. The better the digital clock, the better the quality of your digital audio. The Black Lion Audio Micro Clock MK2 is the most cost-effective major upgrade to your digital studio. Hear the Black Lion Audio difference.

The Micro Clock mk2 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, their 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 mk2 is one of the best performing external word clocks within the pro audio market today.

When Black Lion Audio introduced the Micro Clock mk2 they didn't anticipate the amount of demand and controversy that managed to accompany it. External clocking is certainly a hot button issue. Some folks maintain that there's no basis for it. The reasoning behind this is that the device being clocked externally will simply filter the incoming clock signal through its phase lock loop, thereby eliminating any sort of benefit associated with the superior clock. In addition, read more the simple act of accepting the incoming signal and creating a signal that's in phase will add some jitter.

The biggest problem with this theory is that BLA knows nothing about the PLL filter in question; it's completely hypothetical. Many PLL's in pro audio are designed to filter out unwanted signals that are outside of the desired bandwidth, although some are configured to filter out unwanted harmonics that lie within the signal's frequency band. It's incredibly rare to find one that does both at the same time. In the case of the Micro Clock mk2, there is very little undesirable in-band or out of band content (below 10 picoseconds using a Delta Sigma average). There is, however, an abundance of desirable harmonically related in-band spectral content; more so than the average internal clock. No PLL filter is designed to remove these desirable harmonics; they're busy trying to remove the unwanted stuff. Simply put, the Micro Clock mk2 will not only provide audible improvement to your conversion process, but it will do it as well as or better than any other external clock on the market today.

The Micro Clock mk2 is simple and probably even boring looking by most standards. It's housed in a rugged yet basic 3 inch by 4 inch 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, but that's because those items create unwanted noise that affect the signal. For a modest black box, it does its job incredibly well and at a price that's unheard of for this level of performance!

The power supply is 12 volts DC using a wall wart that's capable of accepting both 120 and 240 volts AC. It features six selectable output frequencies from 44.1 kHz on up to 192 kHz. Output level is approximately 4 volts peak to peak. Jitter at the crystal oscillator is approximately 1 picosecond RMS, and it's just under 10 picoseconds RMS at the output. Both of these figures are obtained using a Delta Sigma averaging method. The Micro Clock mk2 is compatible with all modern digital devices that have 75 ohm BNC word clock input.

This box is AWESOME! There was an immediate, noticeable improvement in my tracks right outa the box! I had no idea how important a good clock is to the quality of the audio.I have more depth, width, and detail. I don't even have a lot of digital gear. I just hooked the Micro Clock up to my digital mixer, and that's it! I HIGHLY recommend purchasing this product!
