The ARX USB DI is a true plug-and-play, professional, digital to analog audio interface that enables sound from a computer to be connected directly to any sound console via the computers USB port, eliminating the need to use any of the computer's existing audio outputs with all their inherent problems.

It features full transformer balanced output isolation to eliminate earth loops and the associated hum, and other extraneous noise and distortion, that is commonly experienced when connecting a computer to a sound system.

The USB DI installs onto the computer as a fully compatible generic USB audio device that is powered from the computer's USB port and requires no special driver software installation on Windows XP, Windows Vista, Windows 7 and Apple Mac OS X.

The USB DI is housed in a heavy duty, all-steel, chassis finished in attractive matt textured powdercoat paint with hard wearing epoxy screen printing and slip resistant rubber pads. It is ideal for interfacing any USB equipped computer (especially notebook computers) with the balanced inputs of professional sound systems.

The USB DI is perfect for schools, theatres and conference centres.
