Rubidium Atomic Clock

Rubicon is the first DAC to integrate a Rubidium atomic clock, which is 100,000 times more stable than a traditional crystal oscillator. Coupled with Antelope’s 64-bit Acoustically Focused Clocking technology, the Rubidium achieves a breakthrough in jitter management, improving the sound quality in an unprecedented way. The same technology is implemented in the company’s flagship master clocks used for scoring blockbusters such as Avatar and available at the best recording and mastering studios around the Globe.

Advanced technological fusion

The transformer-based, ultra-low noise, discrete JFET phono preamp is a complement that will be highly appreciated by many vinyl lovers. In addition to the 384 kHz DAC, Rubicon also includes ultra-high sample rate A/D conversion. These functionalities together with the high resolution USB recording capability provide the users with the sublime experience of digitizing their favorite tracks, still keeping the depth and the warmth of the original analog recordings.

DLNA streaming capability

In addition to the 384 kHz USB streaming, Rubicon offers extended flexibility and smooth user experience provided by the implemented DLNA capability. The DLNA streaming gives users the opportunity to wirelessly push audio files from their smart phone, PC or NAS (Network-attached storage) server and play the content through the high-sample rate DAC.
