The Black Lion Audio Micro Clock MKII Sample Rate Generator is simple and probably even boring looking by most standards. 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. For a modest black box, it does its job incredibly well and at a price that's unheard of for this level of performance!
Black Lion Audio Micro Clock MKII Sample Rate Generator Features:
- Micro Clock MKII is compatible with all modern digital devices that have 75 ohm BNC word clock input
- Features six selectable output frequencies from 44.1 kHz on up to 192 kHz
- Output level is approximately 4 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
- Power supply is 12 volts DC using a wall wart
The Black Lion Audio Micro Clock MKII features ultra low jitter third order crystal oscillators with a revolutionary patent pending high current parallel drive circuit designed to increase the amount of desirable harmonics within the clock's spectral band. In addition to this, its 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 cancellation within the converted audio signal. Because of these technological advances, the Black Lion Audio Micro Clock MKII is one of the best performing external word clocks within the pro audio market today.
When introduced the Micro Clock MKII, Black Lion Audio did not anticipate the amount of demand and controversy that managed to accompany it. External clocking is certainly a hot button issue. Some folks maintain that there's no basis for it; that it's a sort of modern ‘emperor's new clothes.’ The reasoning behind this is that the device being clocked externally will simply filter the incoming clock signal through its phase lock loop, thereby eliminating any sort of benefit associated with the superior clock. In addition, the simple act of accepting the incoming signal and creating a new signal that is in phase will add some jitter.
In the case of the Black Lion Audio Micro Clock MKII, there is very little undesirable in band or out of band content. There is, however, an abundance of desirable harmonically related in band spectral content; more so than the average internal clock. Simply put, the Micro Clock MKII will not only provide audible improvement to your conversion process, but it will do it as well as or better than any other external clock on the market today.
