Antelope Audio Isochrone OCX – No Longer Available

Audio master clock generator
MFR# Isochrone OCX

Product Description

The Antelope Isochrone OCX emerges as the new quality standard in professional master clocks.  A master clock is the heart of the digital studio, essential to maintaining stability and preserving sonic integrity.  It is crucial that a master clock be flawless, and the Isochrone OCX exists to meet this need.  Uncompromised design has created the most stable, best sounding master clock available.

Features

  • Oven controlled discrete transistor crystal
  • Oscillator for lowest jitter
  • Atomic clock input resolves to Rubidium clock for perfect stability
  • Jitter management module improves sonic performance
  • Sample rates 32-192 kHz
  • Factory calibrated to better than +/- 0.02PPM accuracy via Atomic Clock
  • Can be recalibrated in the field to an Atomic Clock for better than +/- 0.02PPM accuracy
  • W/Cx256 "Superclock" output for Digidesign Pro-Tools systems
  • Outputs multiple, divisible sample rates
  • Eight word clock outputs
  • Two AES/EBU outputs
  • Two S/PDIF output

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.

Antelope Clocking. Driven by the Highest Quality Oscillator in Existence.
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.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
