The Indigo DJ from Echo is a CardBus Type II interface for use with notebook computers and features 24-bit/96kHz converters. The interface replaces the notebook computer's onboard sound chip to provide pristine, crystal-clear 4-channel audio playback.
The card offers 2 stereo 1/8 inch analog outputs and also includes a headphone amplifier for powering studio headphones. This high-quality, dual-stereo output device is ideal for listening to CDs or DVDs on the road, mixing professional audio or for use in live performance applications. For live performance, the second output can be used to set up a preview cue mix, separate from the main audio program.
A unique feature of the Indigo DJ 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 outputs 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.
