ART Pro Audio USB-DI USB to Analogue Converter

The USB DI Project Series is a high quality Digital to analogue converter for connecting a computer to a stereo r PA system. It takes in USB audio, converts it to analogue audio and isolates the output using custom transformers. The output isolation is key to removing ground loops and other system noise between the digital and analogue audio systems.

Control
A large knob on the front panel allows for quick, precise control over the output level. A separate headphone output allows you to monitor the system. The front panel Main Output switch allows you to keep the isolated outputs at a fixed level while controlling headphone output level.

Connectivity
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 reference to reduce noise.

Power
The USB DI is powered by USB, drawing less than 200mA and eliminating the need for an external power supply.

Features
• Stepped volume control for easy recall of your previous output settings
• Fixed or variable output switch for allowing control from the unit or the external sound system
• Balanced Isolated outputs with XLR connectors for a robust, clipped connection.
• USB 2.0 connection to the computer for maximum compatibility
• Compact, durable aluminum chassis
