Antelope Audio Pure2 AD/DA Converter

Digital Clarity, Analog Warmth

The Antelope Audio Pure2 AD/DA Converter is a high-end mastering converter, powered by Antelope Audio’s legendary clocking and pristine analog circuitry

The Antelope Audio Pure2 AD/DA Converter is a mastering-grade 24-bit, 192 kHz AD/DA 2-channel converter and master clock that includes a relay-controlled volume attenuator. It features Antelope Audio’s world-renowned Acoustically Focused Clocking (AFC) technology, and also utilizes pristine analog circuitry, driven by a proprietary multi-stage linear power supply for unsurpassed digital clarity and analog realism.

Five High-Performance Components:

The famous Burr-Brown (TI) A/D converter PCM4222 is unsurpassed in terms of sound quality and performance.

A/D Converter with Optimized Overloads Handling:

The famous Burr-Brown (TI) A/D converter PCM4222 is unsurpassed in terms of sound quality and
performance.

D/A Converter with Optimized Dual DAC Architecture:

The separate DAC chips for the left and the right channel tremendously enhance the soundstage and signal-to-noise ratio.

High-End Headphone AMP with Dedicated D/A Converter:

The dedicated headphone DAC not only provides greater convenience and routing flexibility, but the option to monitor a secondary source independent from the main outs.

Relay-Based Analog Volume Control For Accrate Monitoring:

Pure 2 features Antelope’s high end analog volume control with a stepped relay attenuator allowing 0.05 dB precision for optimal monitoring transparency.

Master Clock with 4th Generation of Antelop’s AFC Jitter Management:

The flawless clocking in Pure 2 is ensured by the same oven-controlled crystal oscillator technology from Antelope’s flagship master clock Trinity and the top-seller Orion32 AD/DA.

Flexible Control

Access all Pure 2 features via Mac & PC app or through the front-panel controls

All Pure 2 features are available in an intuitive software control panel for Mac or Windows provides users the ability to manage all facets of the device operation. Pure 2 is also configurable via the front panel with user-definable presets.

Easy Life:

We know the engineer’s life is not a glamorous one. So we tried to make it easier.

You can set up Pure 2 in a couple of minutes. All you actually need is one USB cable (provided in the box) and a laptop of your choosing (Win 7.1 or higher / Mac OSx 10.9 or higher) and you can start capturing stereo audio at 192 kHz.

After setting it up, just download the Control Panel, a few clicks and you’re set.
