Antelope 10MX Rubidium Atomic Clock

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 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.

Fostex HP-V8 vacuum tube headphone amplifier



The power section consists of toroidal power transformers, heater transformers and a choke transformer made by Bando Electronics

Output transformers are custom-made by Hashimoto Electric complying with balanced and unbalanced outputs

The proprietary powering system "Stabilized Tube-controlled Power Ciurcuit (ST-PC)" using KT88 tubes significantly reduces residual noise to achieve S/N ratio of 115dB

E88CC and 300B tubes are used as amplifier tubes and power tubes respectively

The base plate made of aluminum weighing 2kg and the OFC plate with teflon washers used for the power tubes mounting part completely eliminate vibration noise

High anti-vibration rubber feet isolate the chassis from the floor

Pure audio grade electric volume is used to completely eliminate the difference between L and R volumes

Custom-made electrolytic and film capacitors as well as Furutech AC inlet are adopted
