Portable 2-Channel 24-bit/48k with MIDI I/O

The iO2 EXPRESS is a compact, audio-recording interface for home studios and portable recording setups. This two-channel USB device for Mac and PC-based systems enables you to record at up to 24-bit resolution for input into virtually all DAW, recording, and performance software.

This compact recording interface is small enough to comfortably fit into your mobile recording rig, laptop bag, or backpack, yet contains high-quality components and circuitry suitable for the studio.


Discrete-design preamplifiers and true 48-volt phantom power ensure that you capture microphones’ complete signal. High quality analog-to-digital and digital-to-analog converters ensure that every detail of your session or performance gets recorded – and played back on your monitoring system. It’s class compliant, so you can use the plug-and-play iO2 EXPRESS with virtually any computer.

The iO2 EXPRESS is USB bus powered so you won’t need to carry a bulky power supply, and its performance is optimized for minimal laptop battery drain so you’ll be able to track long sessions and gigs remotely.


The iO2 EXPRESS has two input channels. Each channel has an XLR microphone input, a 1/4” TRS insert for external effects units, and a 1/4” TS jack that works with line-level sources and can accommodate direct connection of guitars.

The iO2 EXPRESS sends and receives two audio channels on a single USB cable for simple, universal interface. You can monitor your sessions on any studio monitoring or other loudspeaker system via dual 1/4” balanced outputs. For remote tracking and alternative playback, the iO2 EXPRESS has a 1/4” TRS headphone output.

The iO2 EXPRESS features traditional MIDI In and Out jacks for playing and controlling software with keyboard and pad controllers, workstations, and other MIDI-compatible instruments.


Each channel has a gain trim control, and there’s a master level control for optimal gain staging. When monitoring on headphones, you’ll appreciate the dedicated volume control.

You can also visually monitor levels and operation using the tricolor, stereo metering tree and lighted status indicators.


The iO2 EXPRESS comes complete with a copy of Steinberg Cubase LE digtal audio workstation (DAW) software. Cubase is one of the most popular DAWs in the world thanks to its intuitive approach to composing, recording, editing and mixing.

In addition to the included software, the iO2 EXPRESS is compatible with virtually all audio and MIDI software.

    Comments about Alesis IO2 Express USB Audio Interface:

    I was looking for something to have with me to lay down ideas when they strike...been banging around for months in my van and hasn't broken yet :p It records load AND clear. Doesn't help with vst processing like more expensive units do but it depends what your looking for. you can hear it here all "Van" recording

    Comments about Alesis IO2 Express USB Audio Interface:

    I thought that this Alesis io2 would be a good way to add two tracks and send it via USB to multi-track recording software. At first, I was impressed by the basic features, and the fact that it made two separate tracks/channels possible. It worked great at first yet, the phantom power seems too weak of a boost for my preference. The phantom power that it comes with, is only enough to activate a condenser microphone and make the signal register and function. I connected one channel/track to an effects processor with my guitar, and then my microphone with a tube pre-amp to the second channel/track, and that was the last time it ever worked. I do not think that should have blown it out, it's normal for musicians and engineers to need to chain things together and make circuits. I even tried adjusting the software and changing settings, checking the sample rate, buffers and drivers. But, this thing is toast; I only had it for a year and paid about [$]. At some places these things are up to $99.00! This device would be a fair/good deal, if it was at a much lower price, if it came with a 10 year warranty, if it was durable; able to handle both ordinary and more complicated applications, and if it came with improved phantom power. They really need to improve this thing and drop the price. Otherwise, they are just spiking the price for junk that they will not back up past 45 days or whatever you got*. I recommend, that if you can plug in to a power source, buy a real USB mixer instead, they are so much better for the price. Although this product failed me, Alesis and others are making quality USB mixers with phanton power.
