The Micro Clock MKIII XB is the most accurate word clock we’ve developed to date. With only 0.6pS RMS of jitter at the BNC outputs, it has less than one third of the jitter of the standard Micro Clock MKIII! It boasts incredibly accurate crystal oscillators and superior quality galvanic isolation, both of which contribute to the extraordinarily low jitter measurement.

We spent the better part of a year field-testing the Micro Clock MKIII XB prior to its release, and got a lot of positive feedback on the impact it made in a wide variety of setups. Its small form factor and its ability to drive up to 1,000 feet of coaxial cable make it not only the perfect solution for improving the conversion quality of an audio interface, but also for re-clocking digital mixing consoles at live shows or houses of worship, and as the master word clock in large post-production or broadcast facilities. It can easily sync all of your digital gear together, even if it’s located in different rooms, or different buildings!


Controls Left to Right, see Pics 3 + 4

  1. POWER: engage to turn unit on, disengage to turn unit off
  2. DISPLAY CONTRAST: engage to dim display, disengage to brighten display
  3. FREQUENCY (kHz): rotate three clicks at a moderate speed to unlock and cycle through output frequencies as indicated on the display
  1. BNC Out: 5V, 75Ω output; termination is optional (44.1kHz – 384kHz)
  2. S/PDIF Out: unbalanced RCA output (44.1kHz – 192kHz)
  3. Optical Out: optical S/PDIF output; does not support ADAT (44.1kHz – 96kHz)
  4. AES Out: balanced XLR output (44.1kHz – 192kHz)
  5. DC In: 9VDC center pin positive, input jack (only use a BLA-specified power supply)

Everybody knows that larger setups of converters sound way better if clocked by a single clocking source, not serially – heaven forbid – but parallel with proper termination after each and every component.

I find the BLA Micro Clock unbeatable in this respect for 2 simple reasons:
1) The clock is more than formidable, even a step up from its orgianl version, whoever thought that possible.
Even our decadent and far to expenisve BURL Mothership will sound way better if clocked from the BLA than internally. Way better that is.
2) The BLA Microclock offers a total of 9 Outputs, 6 BNC plus one AES, spdif and optical each.
Whatever digital gear your customers may take to your studio to be incorporated in a session, you will never run out of resources to clock it all perfectly in no time.

Total no brainer.
Just get one.

BTW, get either, new or older version won’t matter much.
Either will improve your studio by a mile.
Of course, if you are areal gear porn nerd (as in “mastering suite”) you’ll need to get the XB  – not that you will sell a single record more 😉
