ART USBDI Overview
The ART USBDI simply converts the USB stereo digital audio signal from your computer into analog audio signal, enabling you to play higher-quality sound over your headphones and speakers. It can be connected to a variety of line-level input devices including mixers, receivers, and powered speakers. The two transformer-isolated balanced XLR line-level outputs are key to removing buzz, hum, and other system noise that could occur between the computer and your analog audio system. A Ground Lift switch adds another level of hum protection. The separate 3.5mm headphone output allows users to monitor the sound using a wide variety of headphone models.
A large knob on the USBDI's front panel allows quick and precise control over the output level. The Main Outputs Fixed/Variable switch allows you to either keep the main XLR outputs at a fixed level while controlling the level of the headphones (Fixed Mode) or adjust the level of the main XLR outputs (Variable Mode). The unit is powered via USB bus power from your computer, eliminating the need for an external power source.
