PURE 2
Mastering AD/DA Converter & Clock
DIGITAL CLARITY, ANALOG WARMTH
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.
Pure 2 Features:
• A/D converter with optimized overload handling
• D/A converter with dual-DAC architecture
• High-end headphone amp with dedicated D/A converter
• Relay-based analog volume control for accurate monitoring
• Master clock with 4th-generation Antelope AFC jitter management
• Connections for S/PDIF, TOSlink, AES, and USB
• Intuitive software control panel for Mac/Windows
FLEXIBLE CONTROL
Access all Pure2 features via Mac & PC app or through the front-panel controls
All Pure2 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. Pure2 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 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.
