Echo Indigo io Cardbus Adapter

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 high quality digital input.

A unique feature of the 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 Indigo IO's "console" software and its on-board DSP. This makes 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 Indigo IO at the same time.[1]


Installation was easy and fast on a Toshiba Satellite M70, 1.86GHz 1GB RAM 100GB HD running WinXP Pro SP3 by following the manufacturers instructions. There were no problems encountered.


You need to select the Indigo io as your default audio device in Start|Settings|Control Panel|Sound and Audio Devices under the Audio tab. Once this is done you need to open Band in a Box and ensure the correct I/O devices are selected. Once this is done BiaB will output audio to the Indigo card.

The output was far superior to the built in card with its RealTek drivers. Indigo boasts the best signal to noise ratio of any consumer level audio interface.

Use of this card has been flawless since installation.


  • The Indigo io Card does not include a midi synthesizer.
  • There are only 2 possible physical inputs, that is the L and R channels on the stereo input. There are 8 "virtual" inputs and outputs, but it would require additional hardware to make use of these in recording more than 2 tracks simultaneously.
  • The ASIO drivers from Echo DON'T work with Band in a Box at any buffer settings. Whether the problem is with the Echo drivers or Band in a Box is unknown at this time. However, as a solution, Asio4All works just fine with very low latency, about 6ms using BiaB 2010 b292, RB 2010 b4, WinXP Pro SP3, Toshiba Satellite M70, 1.86GHz 1GB 100GB HD.
