OCX-V Master Clock

Video-enabled master clock

The OCX-V is a video-enabled audio master clock that offers seamless operation with PAL, NTSC, and over a dozen HDTV standards. Its versatility is taken a step further by supporting simultaneous 0.1% and 4% pull-up/down functionality, enabling unprecedented flexibility. These features, plus impressive gear-boxing functionality make the OCX-V an indispensable tool for any video installation.

High quality crystal oscillator

The core of any master clock is the Crystal Oscillator. While other master clocks cut corners with their Oscillators, Antelope uses the best - Oven Controlled Discrete Transistor Crystal Oscillator. Before Antelope, this component was found only in high-performance aerospace and telecommunication hardware. A better oscillator means better clocking, delivering 4X-6X less jitter and 100 times greater stability than similar products.

Oven-controlled environment

The crystal oscillators in the Isochrone OCX-V are housed in a temperature-controlled oven, as commonly used in military and satellite communication. This keeps the oscillator at a constant temperature making the Isochrone extremely stable.

Proprietary clocking technology

The OCX will noticeably improve the sound quality of connected devices. 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 Igor Levin with his ground breaking Aardsync master clock. This legacy of amazing sound further evolves with AFC. Providing far more than impressive specs, AFC is a hybrid of advanced engineering and exhaustive listening tests designed to deliver extraordinary sound.

...the clarity is fantastic.

Truly astounding!

In particular, the image is greatly improved. It's wider and deeper, and the clarity is fantastic. Since they arrived at The Lodge, the Iscochrone 10M Atomic Clock and the OCX-V are probably the hardest working pieces of gear in our studios!

As one of the most extraordinary mastering engineers in US, Emily Lazar, founder of The Lodge, recognizes the integral role mastering plays in the creative musical process. Combining a decisive old-school style and sensibility with an intuitive and youthful knowledge of music and technology, Emily and her team capture the magic that can only be created in the right studio by the right people. Some of the esteemed artists she has worked with include: Depeche Mode, David Bowie, The Walkmen, Dean & Britta, Lou Reed, Björk, Armin van Buuren, Morrissey, Vampire Weekend, Foo Fighters, Jeff Buckley, Sonic Youth, Third Eye Blind, Natalie Merchant, Aimee Mann, Nadine Coyle (of Girls Aloud), Tiesto, The Shins, Donald Fagen, Beyoncé Knowles, Garbage, BT, The Donnas, The Naked & Famous, Fran Healy (of Travis), Sinéad O’Connor, Destiny’s Child, Noah & The Whale, Simple Plan, Say Anything, The Morning Benders, Wu Tang Clan, Vanessa Carlton, Sondre Lerche, Be Your Own Pet, Nada Surf and The Prodigy to name a few.
