The Micro Clock mk2 is a completely revolutionary design in external clocking from Black Lion Audio. The Micro Clock mk2 is a radical departure in design from its predecessor. It 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, our proprietary noise reduction circuitry dramatically eliminates the unwanted switching harmonics normally found in digital signals.
