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 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.

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.
