OVERVIEW

A 24-bit USB recording interface.

The compact Alesis iO2 EXPRESS audio-recording interface is ideal for home studios and portable recording setups. The 2-channel USB interface 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.

The Alesis i02 EXPRESS recording interface is small enough to comfortably fit into your mobile recording rig, laptop bag, or backpack, yet it contains high-quality components and circuitry suitable for the studio.

Flexible recording and playback
The i02 EXPRESS interface's 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 Alesis 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.

Complete iO
The iO2 EXPRESS has 2 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 Alesis iO2 EXPRESS sends and receives 2 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.

Level management
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.

Complete the package
The Alesis iO2 EXPRESS comes complete with a copy of Steinberg Cubase LE digital 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 Alesis iO2 EXPRESS is compatible with virtually all audio and MIDI software.

  • 2-channel computer audio recording interface

*Technical Issue Update*The issues I was having that I stated back in October of last year are now resolved. Being that the IO2 Express does not have dedicated USB drivers, it relies solely on OS drivers, now the issue was that there is a well known driver conflict that can occur if you have any Logitech Cam installed. Rendering the unit useless via USB. A simple google search regarding Logitech and USB Audio driver conflict will bring up a simple fix requiring you to edit the registry. Once done the unit will now function as promised with only a question of personal taste. I still am disappointed in Alesis' lack of mention for trouble shooting on the product page of their website, in addition to their less than reliable customer service, but the unit now functions properly. This is meant to be a notice for anyone who is experiencing these issues and are about to return it. It will save you and the company you purchased from a headache.

I'll abbreviate this as I was kicked out when adding the final period to my lengthy statement. Controls are extremely touchy and pots have very little useable range. Condenser mics have to be turned up almost all the way. The Cuebase software waveform (Cuebase installation nightmare is another post) Waveform looks like overdriven splatter, but playback is fine. A sleigh turn of the pot up or down, however, gives no signal or a truly splattered signal. BTW, it won't power a high end Schoeps mic but works fine with a cheap sony condenser.

BIG PROBLEM - device no longer works with mu recording computer after upgrading to latest Yosimite Mac OS. Service was very helpful, telling me to use a different computer. This is my expensive field laptop. Come on Alesis, this is a current product and current OS on a common computer. You should have drivers that make this work.

Highly recommended

By Chloe Fields

from Portland

Comments about Alesis iO2 Express Audio Interface:

It's simple, cheap, and gets the job done. I bought this for a live gig and wound up using it as my primary recording device. If you can live with only 2 channles of input, this little device has all you need. Plug and play works beautifully in Windows 7. I've gotten the latency down to 8ms with the ASIO driver.

Great for Beginning Recording

By Stereophobe

from Syracuse, NY

Comments about Alesis iO2 Express Audio Interface:

This is the first USB interface I've owned, and I've been extraordinarily pleased with the quality of it. I get a smooth, clean sound out of both channels when recording through Cubase and Logic, and I never had any technical issues. The phantom power and extra inputs for peripherals are really nice to have for a unit this inexpensive. My one complaint is that I got some distortion in some of the sub-bass frequencies when monitoring (i.e. kickdrums would sound fuzzier than normal), but it wasn't a chronic issue and not a breaking point for someone who's just starting out recording.

Wow.

Comments about Alesis iO2 Express Audio Interface:

This is a pretty sweet interface for the price. I was torn between this and the Lexicon Alpha but I got this for the phantom power. Glad I did. It has zero latency and is packed with features for a unit this price. AND you can record in true stereo. I dig that. Only thing is that some parts feel a little cheap. Oh well; it doesn't leave my desktop, anyway. Overall, you should get it; you won't be disappointed at all, except in the crap software it comes with. Logic is where it's at.

    Comments about Alesis iO2 Express Audio Interface:

    I bought this to replace my old Alesis I/O2 from around 2005. I used that one at live gigs and the studio so it had a lot of miles on it even though it still works. My new I/O2 Express sounds exactly the same (same specs) and is basically the same except for the missing digital in/outs. All other interfaces in this price range (even those for much more) are missing the abilty to monitor the direct/USB mix. This function allows you to monitor what you're recording without any latency or causing the sound card to over work and stutter.

    Comments about Alesis iO2 Express Audio Interface:

    I got this a while back and when I first installed it on a Windows machine, I tried the included cubase software. The onerous DRM was almost a non-starter for me. I fought with the licensing tool and when I finally got everything set up, the volume levels were unusable. Nothing would record despite having the ASIO software installed. I would recommend avoiding the cubase software, there's nothing it offered that seemed better than any free alternative out there.

    I tried it with similar results on Linux and OSX.

    I came back to it a year later with Windows 8 and Audacity and found that everything just worked. It was great. I've only got the one mic, so I'm looking forward to trying a second mic for recording acoustic instruments in stereo.

    Plug and play

    By Anonymous

    from Undisclosed

    Comments about Alesis iO2 Express Audio Interface:

    I have bought it a month ago. It was very easy to setup. After plugging in I recomend to install the asio4all driver also to reduce the latency and the setup is done. Absolutely no other drivers, setting ups, instalation needed. The preamps are really good, and the direct/usb monitor mixing knob is very usefull. As I'm a keyboard player I like the midi interface too. I needed a phatom power too to run my condenser microphone. So its a really all in one product, really thinked over and developed and for small home studios. It is very easy to work with, and perfect choise for home studios.

        Comments about Alesis iO2 Express Audio Interface:

        ATTENTION MAC USERS

        Do NOT buy this. If you plan on using Cubase with it it won't work on Mac. You have to download a driver for it to sound good and you can't because it's only for PC. I plugged it into Garageband and there was really bad hissing. Bottom line is this is way to expensive for how it works in a studio.

          The Alesis took a few hours for me to figure out how set up the audio buses using the Cubase LE 5 DAW, but once I mastered that recording was quick. I really like the flexibiltiy and undetectable latency with monitoring the direct and output signals simultaneously. I am very satisfied with this product for recording electric/acoustic guitar, keyboard, vocals, etc...in my new hobby studio.
