Antelope Audio OCX HD 768 kHz HD Master Clock
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.
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.
Additionally, OCX HD offers two Word Clock Inputs and a Video Sync Input, which can resolve to a huge variety of SD and HD formats, as well as clock distribution with gear-boxing, and pull-up and pull-down rates, as featured in the triple clock powerhouse, Trinity Master Clock. A 10 MHz Input allows for syncing with Antelope’s newest Atomic Clock – 10MX.
Antelope’s latest master clock benefits from flexible firmware update functionality, as featured in all new-generation Antelope products, allowing for fast and easy firmware updates on the user-friendly software control panel, available for both OS X and Windows. The desktop app provides convenient remote control to simplify project workflow. The device is also easily configurable from an elegant front panel, which will add a futuristic aesthetic to any gear rack.

Oven Control
Oscillator accuracy is compromised when exposed to temperature fluctuations. The Isochrone OCX addresses this completely with oven control. The oven’s temperature controlled environment allows unparalleled oscillator stability.Antelopes Jitter Management Module
Jitter free operation is critical in the modern studio. Antelope’s Jitter Management Module makes jitter essentially nonexistent. Adaptive Loop Filtering is taken to the next level with a sophisticated DSP Based Multistage IIR filter, ensuring a jitter free, great sounding studio.Atomic Clock
The Isochrone OCX can be locked to the most accurate clock on Earth: the Atomic clock. A studio can truly achieve perfect stability with the power of Atomic Clock. The OCX, OCX-V and Trinity are the only Master Clocks capable of locking to this unprecedented technology.
Intuitive Design
No nested menus to scroll through, control positions are plainly visible on front panel of the unit.
The core of any master clock is the Crystal Oscillator, and clock performance is impacted greatly by the type of Oscillator used. While other master clocks cut corners with their Oscillators, Antelope chose the best. The Oven Controlled Discrete Transistor Crystal Oscillator is without question the most stable, jitter free in existence. Before the OCX, these oscillators were found only in aerospace and telecommunication hardware designed for critical operations. The OCX is the only master clock to address jitter at the source. Its Oven Controlled Discrete Transistor Oscillator provides 4X-6X less jitter and 100X greater stability than its closest competitor.
Acoustically Focused Clocking, The Next Generation Of DDS Technology
Connecting a device to the OCX will make it sound noticeably better. This is achieved with Antelope’s exclusive Acoustically Focused Clocking technology (AFC). AFC is the 3rd generation of DDS, a technology introduced over ten years ago by Isochrone engineer Igor Levin with his ground breaking Aardsync master clock. The AardSync was immediately recognized as the industry’s best sounding clock. It’s successor, the AardSyncII, provided even greater sonic benefits with its 2nd generation DDS technology. This legacy of amazing sound continues to evolve with AFC. AFC was designed to provide far more than impressive specs, Advanced engineering combined with exhaustive listening tests culminated in AFC’s extraordinary sound.
Peace Of Mind
Clocking is a critical task, and should never be complex. With straightforward controls dedicated to specific tasks, warning lights for critical errors, and a highly visible, accurate frequency display, the OCX’s operating status is apparent with a momentary glance.
