The ART USB IV is a high-quality input/output and 192KHz-capable digital interface for connecting your computer to a wide variety of audio systems. The USB IV contains sample rates from 44.1kHz to 192kHz for computer input and features four inputs that can accommodate any combination of uses including four microphone inputs or two high Z instrument and two line inputs. USB audio is converted using high quality bit stereo DAC to analog audio and custom transformers remove ground loops and other system noise between the digital and analog noise between the digital and analog audio systems. Low latency monitoring is implemented by mixing the inputs with the outputs and is controlled by front panel switches. The USB IV provides both MIDI IN and MIDI OUT though rear panel connections. The front panel headphone output and illuminated input gain knobs allow for on the spot monitoring. With CUBASE LE Software and USB cable included, the USB IV is fully loaded for recording out of the box.
