The ART USB Pre II digital interface takes instrument or mic level signals and converts them with a 32-bit ADC containing sample rates from 44.1kHz to 192kHz for computer input. USB audio is converted using a 32-bit stereo DAC to analog audio. Custom transformers remove ground loops and other system noise between digital and analog audio systems.
