Echo Indigo IO
Cardbus Type II sound card

Echo Indigo IO offers one stereo 1/8 inch analog input and output on a Type II Cardbus card 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 Echo Indigo IO is the use of "virtual" outputs. Indigo IO appears to software as if it has eight separate outputs, which are digitally mixed down to the physical outputs using Echo Indigo IO's "console" software and its on-board DSP. This makes Echo Indigo IO 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 Echo Indigo IO 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.
