Art USBDI Stereo USB D/A Converter with Isolated Outputs - Manual (Page 5)

INTRODUCTION
The USB-DI Project Series is a high quality Digital to Analog Convertor for
connecting a computer to a stereo or PA system. It takes in USB audio, converts
it to analog audio and then isolates the output using custom transformers. The
output isolation is key to removing ground loops and other system noise between
the digital and analog audio systems.
A large knob on the front panel allows quick, precise control over the output level.
A separate headphone output allows you to monitor the system. The front panel
Main Outputs switch allows you to keep the isolated outputs at a fixed level while
controlling level of the Headphones output.
The line level XLR outputs are available for connecting to all sorts of systems.
The Main outputs are always isolated but allow you to control the ground refer-
ence to reduce noise.
The
USB-DI Project Series is powered by USB, drawing less than 200mA and
eliminating the need for an external power.

formers to eliminate the hum and buzz that may be caused by stray voltages and
ground loops. Depending on your application, computers, optical projectors and
many other consumer types of equipment can induce noise in your audio paths.
The
USB-DI Project Series is equipped to cover these problem areas and give
you a great clean audio path.
