From Our Research Team:
The New Quality Standard in Professional Master ClocksTime passes, and unfortunately, sometimes so do clocks. It was a loss for digital studios everywhere when Aardvark's Aardsync II master clock went quietly into that good night. And while we audiophiles mourned the passing of the amazing Aardsync, a testament to the sound quality that it imparted to digital recordings was the fact that no one was selling them on eBay. Cheer up! If ever there was an argument for the existence of reincarnation, it would the emergence of the new Isochrone OCX master clock from Antelope Audio - a master clock boasting truly advanced technology and the soul of the old Aardsync II. That's because the Isochrone OCX is the brainchild of Igor Levin, designer of the original Aardsync and founder of Antelope Audio.
Antelope Audio Isochrone OCX at a Glance:
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 Isochrone 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.
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.
Other master clocks use standard crystal oscillators which don't account for temperature at all, and quality suffers as a result. The indispensable benefits of oven control are found only with Isochrone Clocks.
Antelope's 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.
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.
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, and the OCX is the the only Master Clock capable of locking to this unprecedented technology.
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.
Antelope Audio Isochrone OCX Features:
A master clock is the heart of the digital studio, essential to maintaining stability and preserving sonic integrity. The Isochrone OCX exists to meet this need. Uncompromised design has created one of the most stable, best sounding master clocks available.

I'm a believer
by Jeremy Mang from Kokomo, INI was so used to my system problems and clocking issues that I no longer noticed them as issues. I was very leery to incorporate a piece like this at this cost. Why should I spend that amount of money... read more [+] on something that wont go in my signal chain??

Oh how I was wrong. Two days and two 8 hr sessions later not one crash, blip, hickup... nothing.... Not only that its like I can hear a depth and clarity in my monitors that I had never heard before. Mixing is a joy. I will never be without this ever again.
WHY DIDNT I GET THIS SOONER! close [-]
by Shawn from Providence, RIIt is simple, just buy one. Clarity, depth and it made more excited about mixing. Next Dangerous Music D Box.

Thanks Mark Stein
by David F. from Cleveland, TNI listened to my Sales Engineer - Patrick, in his suggestions and this one required a lot of convincing for me. I have never thought of the need for having a clock and to shell out that money that i ... read more [+]could do so many other things with. But he assured me the need to make my music clearer and my goal of having a top flight studio that competes commercially. Boy was he right - Top engineering friends could walk in and tell a difference. It is very evident that high end gear makes a difference in delivering what your client needs.

The OCX does not disappoint. It blew me away and that is saying a lot coming from being so skeptical about clocking in the first place to owning an OCX close [-]
by Tom Battaglia from Missoula, MTI was very skeptical when shelling out the bucks for this unit. My rep., Paul Rowan assured me that I could return it if I kept it in new condition without racking it, etc. When it arrived, I performe... read more [+]d some tests of playback at 44.1 from some commercially produced stems. In blind A/B comparisons, I was able to identify the OCX half of the time. When I compared test multi-track recordings made (OCX used during recording and playback vs. not) and played back at 48K, I could identify the OCX 100 percent of the time. The material was 11 tracks of drums close mic'd. The effect was clarity vs. muddiness. This is not to say that my interface's clock (RME HDSP RayDAT) is muddy, just that when combined with the OCX there is more clarity and separation. All pre-amp settings, eq, etc. was identical. Tracks were recorded back to back. close [-]

This is a magic box. Plug it into anything that has a digital input and it instantly sounds better. Mixes have more depth and come alive with much more detail.
