Black Lion Audio has announced the release of the Micro Clock MkIII XB, an update to its popular Micro Clock MkIII word clock.

The Micro Clock MkIII XB is the most accurate clock developed by BLA to date. The 0.6 pS RMS jitter spec of the Micro Clock MkIII XB is less than a third that of BLA’s previous flagship clock, the Micro Clock MkIII.

“We spent the better part of a year field-testing the Micro Clock MkIII XB,” BLA CEO Nate Bierdeman noted. “Reactions were overwhelmingly positive. The XB had desirable sonic impact across a wide variety of applications.”

Incredibly accurate crystal oscillators and superior quality galvanic isolation contribute to the extraordinarily low jitter measurement of the Micro Clock MkIII XB’s harmonically enhanced word clock output. Beyond improving the conversion quality of audio interfaces in the studio, the Micro Clock MkIII XB’s diminutive form factor combines with the ability to drive up to 1000 feet of coaxial cable to make it ideal for re-clocking live sound digital mixing consoles, and as the master word clock in large post-production or broadcast facilities.

The front panel of the Micro Clock MkIII XB features a large dimmable clock-frequency display, power switch and frequency selection knob. On the rear are six individually driven word clock outputs on BNC jacks, along with optical (TOSLink), S/PDIF (RCA) and AES (XLR) clock outputs.
