More Details
The DAC1 USB is a mastering-quality, 2-channel 192-kHz 24-bit digital-to-analog audio converter. For more then 10 years, engineers and audiophiles have come to rely on Benchmark for critical digital audio conversion. They consistently find themselves engaged in the music in a way that is rarely achieved with digital converters.
Benchmark has achieved unprecedented sonic purity in their converters through intelligent engineering, eliminating digital distortion artifacts, and maintaining a pristine analog delivery path. The DAC1 USB continues this tradition of excellence
The pristine audio path of the award-winning Classic DAC1 has made it the 'Benchmark' of standalone D-to-A converters. The DAC1 USB preserves the exact topology of the audio path of the Classic DAC1, while adding some of the most frequently requested features.
The DAC1 and DAC1 USB both include Benchmark's jitter-immune UltraLock™ clock system and Benchmark's 0-ohm HPA2™ headphone amplifier. The DAC1 USB features Benchmarks AdvancedUSB technology to ensure bit-transparent, high-resolution playback directly from your computer. The DAC1 USB also includes a programmable mute function that automatically mutes the main outputs upon insertion of a headphone plug. Other features that are exclusive to the DAC1 USB include a programmable headphone gain range, an automatic 'Standby' feature, and a high-current output stage designed to drive even the most difficult loads.
The DAC1 and DAC1 USB feature the HPA2™ - Benchmark's signature high-current, 0-Ohm headphone amplifier. The HPA2™ is arguably the ultimate reference headphone amplifier. It will deliver the full rated performance of the DAC1 and DAC1 USB to the headphones. The HPA2™ maintains less than 0.0003% THD+N under full load. The DAC1 and the DAC1 USB both have two 1/4" headphone jacks on the front panel. The performance of the HPA2™ remains consistent even when two headphones are being driven simultaneously.
