ART USBDI Stereo USB D/A Converter with Isolated Outputs

USB Direct Box

Need to get audio from a computer to a mixer or PA? The USB DI offers high-quality digital-to-analog conversion and balanced XLR outputs, providing a pristine signal to any analog sound system.

Custom output transformers isolate the digital and analog elements, eliminating ground loops and system noise.

A front panel switch selects between a fixed volume at the main outputs or variable adjustment with the Level knob, which also controls the headphone output. A ground lift switch on the rear panel engages an extra layer of hum protection.

The USB DI is class-compliant and bus-powered, so it doesn't require driver software or an external power supply.
