Antelope Audio Pure 2 - Mastering AD/DA Converter & USB Audio Interfac
Description
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. Built for critical listening and precision audio work, this converter earns its place in mastering suites and high-end monitoring chains through transparent performance—the kind of sonic clarity that makes mix decisions reliable and translatable across playback systems.
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 for accurate monitoring and mastering-grade capture. The real performance edge comes from 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 on your masters and mixes.
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 your entire studio to a master reference. 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 integrates seamlessly into your workflow: use the intuitive Mac/Windows software control panel or configure via front-panel presets.

Frequently Asked Questions
What sample rates and bit depths does the Pure 2 support?
The Pure 2 handles 24-bit conversion at sample rates up to 192 kHz, using a Burr-Brown PCM4222 A/D converter and dual-DAC architecture for enhanced stereo imaging and detail.
How does the clocking in the Pure 2 improve my mixes and masters?
The 4th-generation Acoustically Focused Clocking (AFC) technology paired with an oven-controlled crystal oscillator (<±0.02 PPM tolerance) minimizes jitter, which translates directly to more defined stereo imaging, tighter low-end definition, and clearer overall transparency in your finished work.
What kind of inputs and outputs does it have?
The Pure 2 features 2 combo XLR/1/4" TRS balanced analog inputs, main XLR outputs, monitor 1/4" TRS outputs, plus digital connectivity via S/PDIF, TOSlink, AES/EBU, and USB 2.0; it also includes 8 word clock outputs and atomic clock input for external clock synchronization.
Can I control the output level precisely?
Yes—the Pure 2 includes a relay-controlled volume attenuator with 0.05 dB stepped precision and full bypass, and all control happens in the analog domain to avoid digital attenuation artifacts; you can adjust levels via the Mac/Windows software panel or front-panel presets.
Is this suitable for live sound or portable recording?
No—the Pure 2 is designed exclusively for studio mastering and critical monitoring; it requires rack mounting and is best kept in a stationary control room or mastering suite.
