Isochrone OCX achieves the breakthrough clock stability by placing the quartz crystal inan isolated, temperature controlled oven. Constant temperature control of the crystaloscillator and a proprietary Jitter Management Module provide unprecedented sonicbenefits. Isocrone OCX t a k e s t h e d i g it a l s o u n d ou t o f d i g it a l a u d i o, g i v i n g yo u t h e a ud i oin its purest form whether connected to digital mixer, Pro-Tools system, DAW or digitaleffects unit.

The amazingly stable Isochrone OCX can be taken to theultimate level by locking it to the most stable clock on Earth: the Atomic clock.

With added flexibility of being able to output multiple sample rates and the built in supportfor Pro Tools, Isocrone OCX e a si l y s u rp a ss e s t h e i n du s tr y s t an d ar d A ar d Sy n c I I , a nd i sd e s t i ne d t o b e c o me t h e n e w G o l d S t a nd a r d .

Alternate Sample Rate Switches for Word Clock outputs 7 and 8.Word clock outputs 7 and 8 are capable of outputting frequencies different from the OCXinternal clock. The first five settings choose frequencies that are multiples of the internalc l o c k .

When lit, it indicates that a valid sample rate isselected. When flashing, the output has been configured to provide a frequency outsidethe supported range (32kHz- 192 kHz).

For easy reference, the following chart indicates what frequencies outputs 7 and/or 8 willprovide depending on knob position and the selected sample rate.

Word Clock outputs 1-6 The sample rate provided by these BNC outputs alwaysmatches the sample rate indicated by the Frequency Display on the front panel.For best results, WC cables should not exceed 20ft. (6m.) in length. Longer cable runsresult in increased jitter and other clock errors.

Word Clock outputs 7-8The sample rate provided by these two outputs can match the sample rate of outputs 1-6 or be changed to alternate sample rates by using the corresponding knobs on the front panel.
