Black Lion Audio Micro Clock mk2 External Word Clock

Description

The Black Lion Audio Micro Clock mk2 External Word Clock features ultra-low jitter, third order crystal oscillators with a high current parallel drive circuit designed to increase the amount of desirable harmonics within the clock’s spectral band.

In addition to this, a 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 cancellations 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.

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.

The Black Lion Audio 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 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 inputs.

The main features of the Black Lion Audio Micro Clock mk2 External Word Clock include:
