The legendary 10M

DESCRIPTION

Rubidium atomic reference generator

For those refusing to accept compromises in 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.

The ultimate tool in achieving analog sound

The Rubidium Atomic Clock is the perfect companion to the Isochrone audio master clocks such as the OCX or OCX-V

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.

A sturdy mechanical construction

Suited for every environment

The Atomic Clock is distinguished by an extremely sturdy mechanical construction, making it highly resistant to mechanical shocks. In the Antelope tradition of making things easy to use, just connect and power it on; the status lights are visible at a glance and all information is prominently shown on the easy-to-read frequency display.

… My mixes came to life and my low end was punchy and round while my top end had sizzle but not knife stabbing in the ear.”

Rober Dugan Robert has been interested in audio from a very young age and decided to pursue a degree in Audio Engineering. He graduated from SAE Institute of Technology with an outstanding 4.0 GPA. Immediately following, he went on tour all over the world as a Tour Manager, Production Manager, Front of House Engineer, and Monitor engineer working with Grammy winning artist to small bands still trying to make it. Since August 2011 Robert has been working as Production Manager and Front of House Engineer with Mike Posner
