Antelope Audio Pure 2 Mastering AD/DA Converter and Master Clock

Mastering-Grade Conversion for High-Fidelity Audio Workflows
The Antelope Audio Pure 2 is a professional 2x5 mastering AD/DA converter and USB interface designed to deliver precise digital audio conversion and top-tier clocking stability. Ideal for mastering engineers and studio professionals, this unit brings advanced conversion and routing capabilities together with Antelope’s acclaimed 64-bit Acoustically Focused Clocking. Pure 2 combines analog warmth with digital accuracy, providing a pristine signal path for mastering, monitoring, and playback precision.

High-Resolution A/D Conversion with Optimized Analog Handling
Pure 2’s analog-to-digital conversion is built around a Burr-Brown PCM4222 chip, chosen for its outstanding transparency and sonic integrity. The analog input stage is carefully tuned to manage overloads gracefully, ensuring smoother clipping characteristics and a more musical response even in demanding recording conditions. Whether pushing into saturation or capturing delicate details, the Pure 2 offers exceptional control and depth.

Dual DAC Architecture for Enhanced Stereo Imaging
D/A conversion on the Pure 2 uses two separate DAC chips—one for each stereo channel—resulting in improved signal-to-noise ratio, greater channel separation, and highly accurate stereo imaging. This dual DAC approach contributes to a more lifelike and immersive monitoring experience, essential for critical listening environments where spatial detail matters. The output stage delivers clarity, punch, and low distortion, whether used for mixing reference or mastering playback.

Transparent Analog Volume Control for Precision Monitoring
A relay-based stepped attenuator handles volume adjustment on the main outputs with 0.05 dB accuracy. This analog control method ensures transparent gain control with no signal degradation or coloration, allowing for reliable A/B testing and consistent monitoring decisions. The design avoids the pitfalls of digital volume attenuation and is ideal for professional mastering setups where every dB matters.

Dedicated Headphone D/A for Flexible Cue Monitoring
Monitoring flexibility is enhanced by a dedicated headphone DAC and amplifier, which allows users to route and monitor an independent source without interrupting the main output path. This setup is especially useful for mastering engineers needing to cross-reference mixes or cue alternative playback channels. The high-end headphone amp delivers enough power and clarity to handle a range of studio headphones with ease.

Master Clock Stability with 4th Generation Jitter Management
Pure 2 is powered by Antelope’s 64-bit AFC jitter reduction algorithm and oven-controlled crystal oscillator, delivering ultra-stable clocking performance across digital studio gear. Multiple Wordclock outputs allow Pure 2 to serve as the master clock for an entire facility. It also supports synchronization with Antelope’s 10M Atomic Clock, providing even greater timing precision for the most demanding mastering and mixing applications.

Software Control Panel and Preset Management for Workflow Efficiency
A user-friendly software control panel, compatible with both macOS and Windows, allows comprehensive management of routing, volume, and device settings directly from your computer. The front panel also supports user-defined preset slots for quick access to frequently used configurations, simplifying complex workflows and improving session recall across mastering and tracking environments.
