All user reviews of 5/5 for the Alesis iO|2 Express

With its simple yet compact design, the Alesis IO2 is indeed very small and thus very easy to transport.
Thanks to the XLR + guitar/line inputs you can connect mics, guitar, bass, and even a piano without problems. The built-in phantom power allows it to easily handle overhead-type mics, as well as any other condenser mic.

UTILIZATION

Connected via USB to a computer (I have a Macbook pro retina 2014), it allows you to record 2 tracks simultaneously, at 24bits/48kHz, with almost no noise and a more than decent gain. Plug and play on Mac and Windows, it has never left me high and dry, no interferences, and I've never had latency problems (which is very low and imperceptible).

GETTING STARTED

I got it from a friend, so I've never seen the box nor the documentation. But, overall, the design of this small audio interface is excellent and it couldn't be easier to use.
I've never had an issue, it's stable and effective.

OVERALL OPINION

Simple, small and effective, this audio interface is simply...simple. It meets my expectations by being able to record two tracks at 24b/48kHz with almost no latency and a pretty decent sound for this type of product. Furthermore, it's worth mentioning that it does a pretty good job as a soundcard, outputting audio, thanks to tis very comprehensive connections (1/4" jack, SPDIF, MIDI, USB).
A small wonder that I'll keep without hesitation and which, given its small size, will always come in handy in many situations where a bigger interface would be overkill!
So, yes, this small card is simply wonderful! You can buy it with your eyes closed!!

I use it to connect my guitar directly, several mics for vocals or to my amplify my amp directly with the DI output.

UTILIZATION

In terms of drivers, there's not much to say, it's ASIO4all, so there's no problems.
I use cubase 5, with guitar pro 5, overloud TH2, amplitube.
The latencies are all right, not very high but they could be better.

GETTING STARTED

You simply plug it via USB and you're done!
It broke once, I sent it back to Thomann, and two weeks later it was as good as new!

OVERALL OPINION

I've had this soundcard for 2 years and I dream about replacing it (with something of better quality).
It's my first soundcard, so I never tested any other cards before.
I love the card's simplicity, you simply have to plug it in and there's no need to do anything else.
Excellent value for money, I recommend it.

With hindsight, I think I'd buy the same card if I had the same budget.
