Antelope Audio OCX-HD 768kHz HD Master Clock w/ 64-Bit Acoustically Focused Clocking

The Antelope Audio OCX‐HD is a state‐of‐the‐art 768 kHz HD master clock designed for mastering studios, recording facilities, post‐production, film scoring and high‐end live sound environments.

Building on the legacy of Antelope's iconic OCX series, the OCX‐HD sets a new benchmark in clock stability, connectivity and sonic precision.

At its core is Antelope's 4th‐generation 64‐bit Acoustically Focused Clocking (AFC) jitter‐management technology combined with an oven‐controlled crystal oscillator, ensuring exceptionally stable, accurate and musical clock generation. With support for sample rates up to 768 kHz, it delivers ultra‐high‐resolution timing for even the most demanding production workflows.

The OCX‐HD offers one of the industry's most comprehensive clocking I/O configurations: 10 Word Clock outputs, four AES/EBU outputs, two S/PDIF outputs, plus two Word Clock inputs, AES/EBU and S/PDIF inputs, and a Video Sync input supporting a wide range of SD and HD formats.

Designed for modern hybrid studios, the OCX‐HD features full software control via USB, enabling remote configuration, firmware updates, preset loading and detailed monitoring from macOS or Windows.
