It is crucial that a master clock be flawless, and the Isochrone OCXHD exists to meet this need. Uncompromised design has created the most stable, best sounding clock.
A new quality standard in professional master clocks
The Antelope's Isochrone OCXHD 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.
Jitter Management Module
Low jitter operation is critical in the modern studio. Antelope's Jitter Management Module implemented in Isochrone OCX 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.
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.
Atomic clock input
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 OCXHD and Trinity are the only Master Clocks capable of locking to this unprecedented technology.
