Antelope Audio 10M Atomic Clock - Manual (Page 5)

Introduction
Thank you for purchasing this 10M Rubidium Atomic Clock the foremost device in the Antelope’s
ISOCHRONE product line specifically designed for the most discerning audio professionals. Before
you begin operating this unit, please read the instructions carefully to make sure you handle the
device properly and get the best possible performance.
Product Overview
ISOCHRONE 10M is a laboratory-grade atomic master clock for audio/video equipment and for
other uses for which ultra-high clocking precision is required. In audio, it virtually eliminates jitter by
providing your gear with clocking reference which is so stable that some testing instruments cannot
even measure it: 0.03 PPB (parts per BILLION), that is, deviation of 1 second in 1,000 years! As a
result, staging, transparency, imaging, separation, and depth are vastly improved and render the
warmth and fullness typically associated with analog sound.
The heart of the ISOCHRONE 10M is a Swiss-made high precision sub-miniature Rubidium
oscillator, which is 100,000 times more stable than the typical crystal oscillator. Rubidium is a very
soft and highly reactive element forming alloys even with gold, but it is best known for its capacity
to produce extremely stable sinusoidal frequencies. In this device, it generates a frequency of 10
MHz, hence the name “10M”.
You can use your ISOCHRONE 10M with any device that supports 10MHz (BNC) input clock. The
ISOCHRONE 10M can clock up to 8 devices simultaneously.
ISOCHRONE 10M has dual redundant power supply (100-240V AC and 15 V DC), which eliminates
downtime in case of power failure.
Note: Even though the device is an atomic clock, there are no radioactive components inside
ISOCHRONE 10M.
