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

Pure2 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:

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 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 a 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 accurate monitoring

Pure2 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 Antelope’s AFC jitter management

The flawless clocking in Pure2 is ensured by the same oven-controlled crystal oscillator technology from Antelope’s flagship master clock Trinity and the top-seller Orion32 AD/DA.

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

You can set up Pure2 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.
