The Antelope OCX HD is a premium-grade master clock designed for high-resolution audio and video production environments. Building on the legacy of Antelope’s respected OCX line, the Antelope OCX HD combines refined timing accuracy with advanced connectivity to meet the demands of modern studios working at sample rates up to 768 kHz.
At the heart of the Antelope OCX HD is Antelope’s proprietary 4th generation Acoustically Focused Clocking (AFC) technology, backed by a high-stability oven-controlled crystal oscillator (OCXO). This technology provides exceptional clock signal integrity, reducing jitter and enhancing the sonic detail and stereo image of digital systems. The OCX HD is capable of delivering precise clocking to a wide range of connected devices with 10 word clock outputs on BNC, four AES/EBU outputs on XLR, and two S/PDIF outputs on RCA.
In addition to audio clocking, the Antelope OCX HD includes a video sync generator with support for all common SD and HD formats, making it suitable for post-production and broadcast environments. Users can sync the Antelope OCX HD to an external 10 MHz atomic clock or use it as the master source. Sample rate selection is straightforward via front panel controls and a dedicated display, allowing quick switching between rates ranging from 32 kHz to 768 kHz.
The unit offers multiple pull-up and pull-down options and varispeed functionality for flexible system integration. Its rugged 1U rackmount chassis and user-friendly interface ensure it is equally at home in mastering studios, film dubbing stages, or live broadcast settings.
With class-leading specifications, reliable long-term performance, and extensive format support, the Antelope OCX HD is a world-class clocking solution built to serve as the central timing reference in professional audio and video systems.
