In keeping with our policy of creating essential audio interfaces, ARX is excited to present the new ARX USB I/O - a true Plug and Play USB digital/analog pro audio interface. It removes the need to use any existing sound card outputs, with their inherent noisy environment and problematic grounding.

Based on the same expanded Audibox Plus platform as the DI Plus and Plus 2 Rechargeable Direct boxes, the ARX USB I/O features full transformer balanced Inputs and Outputs, providing the isolation required to eliminate earth loops / ground hum and other extraneous interaction noise and distortion.

Plug and Play

The ARX USB I/O installs as a fully compatible generic USB audio device, requiring no special driver program installation on Mac OSX, Win XP, Vista and Win7.

The front panel has Left and Right transformer balanced analog XLR Input and output connectors that connect to any standard balanced analog inputs and outputs. On the rear panel there is a Type B USB connector, as well as a ground lift switch. A status LED on the rear panel indicates that the USB I/O is connected and operating.

The USB I/O is housed in a heavy duty all-steel chassis finished in attractive matt textured powdercoat, with hardwearing epoxy screen printing and slip resistant rubber pads. It is ideal for interfacing any USB equipped computer (especially notebook/laptop computers) with the balanced inputs and outputs of professional sound systems.
Security features include Kensington®-type computer lock slot and optional bracket kit for under-table mounting.

The ARX USB I/O is available in Dual Channel format, and is hand made in Australia
