Benchmark DAC1 USB - 2 Channel DA Converter 24-bit 192 kHz
The DAC1 USB is a mastering-quality, 2-channel 192-kHz 24-bit digital-to-analog audio converter. Engineers and audiophiles have grown to rely on Benchmark for critical digital audio conversion for more then 10 years. They are consistently finding themselves engaged in the music in a way that is rarely achieved with digital converters. 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 Benchmark’s AdvancedUSB™ technology to ensure bit-transparent, high-resolution playback directly from your computer. The DAC1 USB also includes a ‘mains-mute’ function that automatically mutes the main outputs upon insertion of a headphone plug.
Other features that are exclusive to the DAC1 USB include selectable headphone gain ranges, an automatic standby feature, and a high-current output stage designed to drive even the most difficult loads. AdvancedUSB™ responds automatically to sample-rate changes to bypass the operating system’s sample-rate conversion. The DAC1 USB achieves transparent, audiophile-quality playback through a true plug-and-play solution. It is very important to have a 24-bit USB path, even for 16-bit playback, because digital volume controls and other DSP function s can increase 16-bit audio to 24 bits. If a 16-bit USB interface is used, up to 8 bits of each digital audio sample will be truncated - resulting in significant, non-musical digital distortion at audible levels. Benchmark converters perform with unprecedented sonic purity through intelligent engineering - eliminating digital distortion artifacts and achieving a pristine analog delivery path. The DAC1 USB continues this tradition of excellence.
