Antelope Audio Pure 2 - Mastering AD/DA Converter & USB Audio Interfac

Antelope Audio Pure 2 - Mastering AD/DA Converter & Master Clock

The Pure 2 occupies a slim 1U footprint while delivering mastering-grade conversion and world-class clocking in a remarkably compact form factor. This is a serious tool designed for critical listening and precision audio work—the kind of device that earns its place in mastering suites and high-end monitoring chains through transparent performance rather than flashy features.

Conversion & Clocking Performance

Built around 24-bit, 192 kHz AD/DA conversion with a Burr-Brown PCM4222 A/D converter and dual-DAC architecture, the Pure 2 delivers exceptional clarity and stereo imaging. The real differentiator is Antelope Audio's 4th-generation Acoustically Focused Clocking (AFC) technology paired with oven-controlled crystal oscillator clocking—this jitter management directly translates to more defined imaging and tighter low-end definition in your masters.

Connectivity & Control

Comprehensive I/O includes S/PDIF, TOSlink, AES, and USB 2.0 Hi-Speed connections, plus 8 word clock outputs and atomic clock input capability for syncing to external master clocks. Volume control comes via relay-controlled attenuator with 0.05dB precision and full bypass—analog-domain control ensures clean monitoring without digital attenuation artifacts. Control is seamless: use the intuitive Mac/Windows software control panel or configure via front-panel presets.
