The Micro Clock mk2 from Black Lion Audio is an external Wordclock generator that 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 an attempt to minimize noise that might affect the signal, the company has dispensed with any unneeded peripheral components such as lights, or a frequency display, and housed the unit in a basic and rugged chassis that provides optimum RF shielding.
