Echo Indigo IOX Express Card

ExpressCard notebook pro audio recording has never sounded so good, or been this convenient and affordable. Indigo IOx offers one stereo 1/8 inch analog input and output on an ExpressCard powered by your notebook computer. It combines this with 24-bit/96kHz converters for the quality you deserve. Also included is a 6 foot audio cable for RCA or 1/4 inch connections.
A unique feature of the Indigo IOx is the use of "virtual" outputs. Indigo IOx appears to software as if it has eight separate outputs, which are digitally mixed down to the physical outputs using Indigo IOx's "console" software and its on-board DSP. This makes Indigo IOx compatible with all popular multi-track software. And, with Echo's "multi-client" drivers, more than one application (such as an editor and a software synth) can be playing back through Indigo IOx at the same time.

Product Specifications 
Echo Digital Audio is proud to use only specifications of production units. While other companies quote specs of their converters alone in laboratory settings, the numbers you see on this page represent the actual unit in your hands. Since people often rely heavily on specs when deciding what gear to buy, we like to bring you numbers that really mean something.
