The Black Lion Audio Micro Clock MK2 is a high-quality external clock with ultra-low jitter, designed to keep your entire digital audio rig marching in perfect time. With three 75ohm BNC outputs and sample rates from 44.1kHz all the way through 192kHz, the Micro Clock MK2 is a marked improvement over the internal clock of most consumer-level interfaces and can subtly broaden the sound stage and clean up the sound of your converters.
