ART USB Pre IV 4x4 USB Audio Interface

The ART USB Pre IV is a high-quality 4-input/4-output 192 kHz capable digital interface. The inputs can accommodate any combination of uses including 4 microphone inputs or two high Z instrument and two-line inputs.

The USB Pre IV takes instrument or mic level signals and converts them with a 32-bit ADC containing sample rates from 44.1 to 192 kHz 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 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. Channels 1 & 2 are balanced transformer isolated outputs. Channels 3 & 4 are sent out through the headphone output jack.

The USB IV provides both MIDI IN and MIDI OUT though rear panel connections. The sample rate is set via the USB interface and its low latency ASIO/WDM driver.
