SPATIAL offers the world's best external digital clocks in order to take our systems to the highest attainable performance level. High accuracy outboard word clocks improve the sound of the DAC and can be added at any time. Antelope Audio from England produces the world's finest clocking devices and we are excited to be able to offer them to our customers. All models are available in Black or Silver.

Audio Master Clock Generator
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.

For those refusing to accept compromises with audio quality there is the Isochrone 10M - a Rubidium Atomic Reference Generator based on real atomic technology. The 10M is designed specifically to appeal to the most discerning audiophiles and audio professionals. If your goal is to set up your system for maximum performance, you will certainly appreciate a clocking reference that is a staggering 100,000 times more accurate than the quartz oscillators used in most equipment.

Swiss-made Rubidium core for use as the clock source generator for OCX, and Trinity
Isochrone 10M brings to your system the most accurate clock on Earth - the Atomic clock. With the deviation of 1 second in 1,000 years, it is a real quantum leap in clocking technology, making all other reference generators pale by comparison. The heart of the Isochrone 10M is its Swiss-made, high precision sub-miniature Rubidium oscillator, capable of producing extremely stable sinusoidal frequencies.

Isochrone 10M renders unsurpassed audio quality. Because of its staggering precision, Isochrone 10M virtually eliminates any traces of jitter. If you have invested in top quality equipment and state-of-the-art audio, you need the 10M to realize the full potential of your gear. The atomic clock eliminates the last weak link in your system.

The Rubidium Atomic Clock is the perfect companion to the Isochrone audio master clocks such as the OCX or Trinity. When connected to the Isochrone 10M, these devices switch over automatically from oven based crystal to the superior Rubidium Core. Isochrone 10M is the ultimate tool in achieving analog sound. Experts agree that 10M is probably “the best sounding clock” ever produced.
