The Indigo IO from Echo is a CardBus Type II interface for use with notebook computers and features 24-bit/96kHz converters. The interface replaces the computer's onboard sound chip to provide pristine, crystal-clear full duplex 2 channel input, and 2 channel output 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 card offers 2 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 8 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.
