INTRODUCTION
The NuForce μDAC is a high-performance USB Digital Audio Converter (DAC) that connects your personal computer’s audio to your home stereo, desktop sound system, or headphones. The quality and versatility of the μDAC’s performance belie its diminutive size. With its extensive power supply, filtering capabilities, and charge-pump circuit as a foundation, the μDAC accurately processes incoming data via a USB audio receiver. A D/A converter stage then translates the data into an analog signal with a robust 2.0-Vrms-output capability. The NuForce μDAC’s performance equals or exceeds that of a great many audiophile CD players. The unit’s exemplary flexibility –– analog RCA, digital coaxial, and high-performance headphone outputs –– is bound to satisfy the needs of the most critical music lover.
