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

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

The Pure 2 packs mastering-grade conversion and world-class clocking into a slim 1U footprint—serious sonic architecture for musicians and engineers who demand transparent, honest monitoring of their work. This is the kind of device that becomes invisible in the signal chain, letting you hear exactly what you're playing and recording without coloration or compromise.

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 the clarity and stereo imaging you need to trust your mixes and monitor chains. The real sonic advantage is Antelope Audio's 4th-generation Acoustically Focused Clocking (AFC) technology paired with oven-controlled crystal oscillator clocking—this precision jitter management means your low end locks in tight, your imaging stays defined, and every detail stays audible from first note to final master.

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 keeps your monitoring chain clean without digital attenuation artifacts that cloud your ears. Control is straightforward: use the intuitive Mac/Windows software control panel or configure via front-panel presets.
