Antelope Audio has just introduced Rubicon, a 384 kHz digital audio preamplifier which integrates a 10M Rubidium atomic clock. According to Antelope, Rubicon is the first DAC to integrate a Rubidium atomic clock, which is spec’d to be 100,000 times more stable than a traditional crystal oscillator. Coupled with a 64-bit acoustically focused clocking technology, the Rubidium supposedly achieves a breakthrough in jitter management, improving the sound quality.

In addition to the 384 kHz DAC, Rubicon also includes ultra-high sample rate A/D conversion. These functionalities, together with the USB recording capability, provide the users with the ability to digitize their favorite tracks while keeping the “warmth” of the original analog recordings. 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.

Inputs include:

• 1x PHONO Input on RCA
• 3x Inputs on RCA
• 1x HiZ Input on RCA
• 1x Combo Balanced Input on XLR/¼ TRS
