Antelope Audio Pure2 Mastering AD/DA Converter and Clock provides digital clarity and 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.
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.
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.
