10MX features the atomic precision of 10M and Trinity’s groundbreaking jitter management algorithm

10MX is the newest and the premier member of the Isochrone family. It features technologies from two of Antelope’s legendary products. The atomic precision of the 10M and the sophisticated jitter-management algorithm of Trinity are combined in a futuristic, 1U rack space enclosure, providing the world’s most stable and musical clocking.

10MX is a fusion of proven technologies and contemporary industrial design, where no compromises are allowed and both build-quality, and performance-excellence are top priority. The new Rubidium Atomic Clock is an epiphany of more than 20 years’ expertise in the digital audio world, making vividly real the clarity, depth, width and 3-dimensionality distinctive of the analog sound.

10mx features

4 WORD CLOCK outputs

The master clock beast: 4 Word Clock outputs allowing up to 768 kHz


Flawless clocking powered by Antelope Audio’s world-renowned jitter management algorithm


The 10MX’s multiple atomic outputs allow up to 10 devices to be simultaneously clocked

Additional outputs

2 x S/PDIF and 2 x AES/EBU master clocking outputs up to 192 kHz


Intuitive Software Control Panel

PC/Mac connection

PC/Mac connection via USB, allowing remote control and firmware upgrades

10M & Trinity’s legacy



10MX fits any studio environment – from recording to mixing and mastering

10MX is perfectly suited for recording, mixing and mastering environments. Its form factor, occupying only 1U of rack space, makes it ideal for live sound application where rack slots are precious commodity.

The multiple atomic outputs allow up to 10 devices to be clocked simultaneously over BNC outputs of 10MHz. The unit can also be used as a master clock with 4 outputs, supporting the outstanding sampling rate of up to 768 kHz via BNC. Two more clocking outputs are available via AES and two via S/PDIF.
