    Easy to hook up, but the included Cubase software is a total pain to activate--so I downloaded Audacity for free online which works fine. The bit rates the maunual tells you to assign for Windows 7 arent available, but I picked the closest one and the unit worked fine. You do have to modulate the gain/volume quite a bit to get the best results. I use the unit with a Korg M50 Keyboard and was shocked at how good the WAV file sounded with better than CD quality.

    Comments about Alesis iO2 Express USB Audio Interface:

    I am a novice when it comes to audio recording/ home studio set-ups... That being said I am pleased with how the i02 express performs. Not the sturdiest build, but built as expected at that price point. With a little trial-and-error I was able to successfully record with my DAW on a Windows 7 box and I have no complaints with sound quality. This device isn't exactly plug-n-play, but not complicated if you have good understanding on how Windows Audio devices & soundcards work (and how to use ASIO4All drivers for your DAW). I cannot compare this device to other "professional" tools since I am new to home recording, but I am having fun learning how to record (bad) music with it !

    Comments about Alesis iO2 Express USB Audio Interface:

    I find most video places put audio in second place. While the iO2 is an easy hook up, you really have to crank the pots for any quality volume. And then it's weak at best. I used to use a Delta 88, but those are long gone. I'm sure there are better products on the market, but this was a good price, and of course NOBODY beats B&H when it comes to service. Since I bought it I will tolerate it for now. I used to shop at [*]. What they don't know about customer service would fill volumes. All the best to B&H. Glad I found you.

          A super portable, compact audio interface for my Mac.
          WIth built in pre-amps and 48-volt phantom power it features 2 XLR inputs with a 1/4 inch TRS instrument jack and insert jack. It can accept line level signals or a direct guitar connection by simply flicking the switch on the front.
          It's cheap, it's useful and looks nice and just gets the job done. This will be certainly living in my laptop bag and going with me when I just have to capture an idea!

            Comments about Alesis iO2 Express USB Audio Interface:

            This unit is "class compliant" which means that with a modern machine, running modern OS (except possibly windoze 8) it should work. I bought four of them and they have stood up to fairly vigorous student use (7-12 grades) for a full year.

            The trick is to figure out how your system routes the signal. We had all kinds of trouble until we figured this out. Both the computer itself and your DAW have to be set to use the signal to/from the IOS. It should show up as "mono 1 io2" or something like that. Sometimes the computer seems to switch these settings at random, but it could just be students doing it. It is a great deal for the money.

            I wish the unit felt a bit sturdier, but like I said, it has held up.

              This interface is very convenient for small scale recording, and has simple and straightforward controls. I use it for direct bass guitar recording and mic'd vocals and other guitars. The USB-powered interface saves a lot of set-up convenience.

              All features worked for me out-of-the-box with the Linux-based DAW, Ardour.

                      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. It's made so that two separate tracks and multi channels are possible. That's a step up from the lower end products still out there. At first, I liked the basic features yet, most plug in powered USB mixers have many more than this USB powered IO device. It worked o.k. 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. You could tweak the signal once it's in the software but, I have seen phantom power that was much more intense, warmer and fuller. What broke mine is when I connected my effects processor and my guitar to one track/channel, and then my microphone and tube pre-amp, to the second track/channel. That was the last time it ever worked. I do not think that should have blown it out, its normal activity for musicians and engineers to need to chain things together and make circuits. I tried to fix it, by adjusting and checking the software settings, sample rate, buffers, sound card, and drivers. But, this thing is toast; and I only had it for a year. This device would be a fair/good deal, if it was at a much lower price, came with a 10 year warranty and if it was durable; able to handle both ordinary and more complicated applications, and also if it came with improved phantom power. They really need to improve this thing and drop the price. Otherwise, you pay a spiked price for junk that they will not back up past 45 days, or whatever the policy and warranty. I highly recommend, that if you can plug into a power source, buy a real mixer with USB instead. A wall plug in powered USB mixer with phantom power is usually always higher quality, has more features, greater value for a comparably better price. Check those out instead of this toy, and if you need a USB powered IO device, maybe try something else and put a warranty on it.

                      This audio interface works great . Just plug in your mic and guitar start up audacity or whatever multi-track and start recording. You can mix your channels even plug in a piano or drum set into the midi. It does everything I need and was very affordable.

                        The Alesis Io2 is a simple to use product. Specially when used with an ipad2 using Garageband.
                        When connected to Roland GI 20 midi guitar you can use the ipad to compose, improvise, record and just have fun using a Godin Guitar as a controller. You need an external USB power Hub to have the right power to get the signal into the ipad.
                        What a dream come true.

                        The Cubase is a oem product with ZERO support. It is very complicated to use. It is almost useless when you compare to the new generation software such as GarageBand on an ipad2. It is made for programmers and not reagular musicians.

                        Bought this to replace a Tascam interface that used 20% of CPU even when it was idle. The Alesis was recognized as soon as I plugged it into my Windows XP laptop, did everything well right out of the box. Uses hardly any CPU even when it's playing/recording. I'm not using the mic inputs because I use a real mixer in my studio, but everything else on it works just like it should.
