The Indigo IO is a Type II Cardbus card for use with laptop computers and features 24-bit/96kHz converters. The card replaces the notebook computer's onboard sound chip to provide pristine, crystal-clear full duplex two channel in, two channel out operation.
This high quality stereo input/output device is ideal for listening to CDs or DVDs on the road, mixing professional audio and it can even be used for live performance applications. The Indigo IO offers two stereo 1/8 inch analog connectors, one for input, the other for output. It also includes a headphone amplifier for powering studio headphones.
A unique feature of the Indigo IO is the use of "virtual" outputs. The card appears to software as if it has eight separate outputs, which are digitally mixed down to the physical output using the supplied "console" software and its on-board DSP. This makes for compatibility with all popular multi-track software. And with Echo's "multi-client" drivers, more than one application, such as an editor and a software synthesizer, can be playing back at the same time.
