Antelope Audio’s 10M Atomic Clock will bring out the sonic details you’ve always dreamed of experiencing

To get ultimate sonic performance from your system, you need a clock with absolute accuracy and virtually zero jitter. The new Audiophile 10M Atomic Clock is a 10MHz rubidium atomic reference generator that, paired with Antelope’s renowned clocking algorithm, delivers astonishing audio quality. 100,000 times more stable than a typical crystal oscillator, the hyperfine energy levels of the non-radioactive rubidium core enable high-precision timing to 0.03 parts per billion, which equates to a loss of just one second per 1000 years!

All aspects of your sound will benefit – staging and imaging will become pin-sharp, and spectral separation and depth will gain clarity, detail, and range. The result will be the analogue immersion, dynamics, and detail that you always wished for.

10M is the preferred clock for trendsetting producers, audio engineers, artists and movie post-production studios

The Audiophile 10M Atomic Clock (a.k.a. Baby 10M) is an upgraded and enhanced version of the Antelope’s Isochrone 10M, which has become a new industry standard for ensuring audio quality and accurate sound reproduction. Leading producers, sound engineers, artists, and movie post production studios worldwide are using the 10M Atomic Clock together with our high-end Trinity master clock. They usually describe it as “mind-blowing”, an “instantaneous improvement”, “superior”, and fundamental in bringing “more detail, ambiance, and naturalness” to the digital signal. The results are described as “wider and more solid” with “crisp transients and a 3D depth of field.”
This experience is no longer exclusive to music and film studios. Exactly the same clocking technology and atomic precision is now available to the home audio listener.


10M is Zodiac Platinum’s best friend

The Audiophile 10M is especially designed to match the aesthetics of the Zodiac Platinum DSD DAC, which also has a direct 10MHz input. The pair are visually and technically perfect for each other, and together they transfer high-end studio technology directly to the home environment. With the Zodiac Platinum / 10M combo, for the first time ever, the home listener has the chance to experience the music with the same technology it was created with, sounding exactly the way it was meant to by the sound engineers that worked on it.


Use 10M with any device with a 10 MHz (BNC) input and clock two units simultaneously

Bring the original, unspoilt source to your speakers simply by connecting this ultra-accurate 10MHz clock and turning it on. The Zodiac Platinum DSD DAC will automatically switch from its crystal oscillator to the atomic clock reference, still using the 4th generation of Acoustically Focused Clocking algorithm implemented in the DAC, the same as it is in the top level Trinity Master Clock.

You can use your Audiophile 10M Atomic Clock with any device that supports 10MHz (BNC) input clock and clock two devices simultaneously.


The 10M Atomic Clock was designed to endure and stay eco-friendly

The Audiophile 10M Atomic Clock is made from only high-grade materials, including a custom-machined aluminum front panel. This sturdy mechanical construction makes it highly resistant to mechanical shocks. The much smaller chassis and heat sink of the Baby 10M, compared to that of its elder brother, is due to the implementation of energy saving technology, allowing three times less power consumption and thus a greatly reduced heat level.
