The perfect solution for mastering, recording and project studios, film-scoring, post-production and live sound

For over a decade, Antelope’s legendary OCX Master Clock has been a dominant force in the audio world.

This legacy now continues with the newest master clock by Antelope Audio – Isochrone OCX HD.

The New Standard In Clocking

OCX HD and the vast choice of clocking options it offers studio professionals make it the most versatile audio clock on the market

OCX HD raises the bar yet again, delivering sample rate support of up to 768 kHz, Antelope’s best-in-class 4th generation Acoustically Focused Clocking (AFC) jitter management algorithm and oven-controlled crystal oscillator.

OCX HD Master Clock offers a great variety of clocking options – 10 configurable in pairs Word Clock Outputs on BNC, four AES/EBU Outputs and two more on S/PDIF. This vast assortment of connectivity makes the OCX HD the most versatile audio master clock on the market, while proven, proprietary clocking technology delivers the most musical and reliable audio sync generation on the market.
