• 1U removable rack ears

The Black Lion Micro Clock M III is a master clock generator to synchronise all of your digital equipment.


The Micro Clock MkIII is a significant redesign of its predecessor, the Micro Clock MkII. Core technological improvements include lower-jitter crystal oscillators, higher-quality galvanic transformer isolation in the signal path, dedicated output drivers with better isolation, higher-precision signal division, and much heavier noise filtration throughout the circuit. All of this results in a more robust, lower-jitter clock signal than the Micro Clock MkII, with even more desirable harmonics in the clock's spectral band that impart an undeniable musical quality to the conversion process. The feature set has expanded to include an LED frequency display, six BNC outputs capable of up to 384kHz, AES and RCA S/PDIF outputs capable of up to 192kHz, an optical S/PDIF output capable of up to 96kHz, and removable 1U rack ears.
