ART is proud to introduce the  USB Pre IV.  This new digital interface is a high quality input/output and 192KHz capable digital interface for connecting a computer to a wide variety of audio systems.

The USB IV 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 the digital and analog noise between the digital and analog audio systems

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

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.
