The original Indigo has been discontinued. The Indigo io and Indigo dj are still available for purchase. Some information on this page may no longer be up-to-date.

It's the original award-winning Echo Indigo pro audio playback card! People all over the world have discovered the joy of listening to high fidelity audio on their notebook computers with the Indigo. No more noise!! The Indigo replaces your notebook computer's onboard sound chip to give you pristine, crystal-clear audio playback.

This high quality stereo output device is ideal for listening to CDs and DVDs on the road, mixing professional audio, and you can even use it for live performance applications. The Indigo offers one stereo 1/8 inch analog 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. It also includes a headphone amplifier for powering studio headphones, and the stereo output is duplicated on a second jack so you can share your music with a friend.

A unique feature of the Indigo is the use of "virtual" outputs. Indigo appears to software as if it has eight separate outputs, which are digitally mixed down to the physical outputs using Indigo's "console" software and its on-board DSP. This makes Indigo 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 at the same time.
