ART USB Pre II 2x2 USB Audio Interface

Need a solid, affordable audio interface with 2 mic/line/instrument inputs, 5-pin MIDI I/O, and 192 kHz resolution? ART has you covered with the USB Pre II.

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.
