If you have audio or digital devices with a word clock input then you need this master clock to synchronize their operation.
The Black Lion Audio Micro Clock MKIII XB is an ultra-tweaked version of the company's popular Micro Clock MKIII master clock. Through painstaking engineering, Black Lion reduced the jitter by two-thirds and spec'd their flagship clock with super-accurate crystal oscillators and high-caliber galvanic isolation, both of which contribute to the exemplary jitter performance.
