Perfect entry level interface

the io2 is the perfect entry level interface, it delivers high enough sound quality to record band demos, voice overs, any amateur level application really. however, the total harmonic distortion of the preamp/converters is not as good as more expensive preamps. what this means is that if you want to make a really loud track with pristine audio quality, you need better preamps to allow for better compression and gain when finishing tracks. this is perfect for people making a start at recording. this would not be perfect for musicians who want commercial sound levels.

Alesis iO2

I needed a quick way to get clean audio in and out of my secondary Pro Tools system. For $99 the iO2 seems to fill the bill. While I have not really put it through its paces, it works as advertised, and sounds good. My only complaint (but what do you want for $99) is the cheezy shiny silver plastic knobs, which are NOT the knobs that are shown in the picture. They just feel very cheap, and the knurled white plastic knobs shown in the photo would have been preferred, and would look more professional.

Does what is says it does...

Bought this to get a low cost interface for playing VSTi's from my notebook. Simple installation and hardeware interface, not like the rocket science needed to work with my EMU-1820M on my desktop PC. I recommend it for keyboardists/guitarists, or anyone not needing a lot of I/O for recording live bands (i.e., more than stereo).

Decent for a few months..

Gave me little feedback and decent tone through my setup. Worked for four or five months, then at the WORST possible moment (right before a session) the USB output stopped taking a charge. The gain meter stays in the red every second it is plugged in, and no audio will make it through to my monitors from the PC. I had a short warranty that came with it and it actually expired right before it died. Ah well, I moved on to an 11 Rack. Good for beginners with absolutely no other options. I would say you should still go for an M-Box instead. Alesis customer service is god-awful.

Solidly built but limited

Could not get to work with Cakewalk Sonar. No problem with Propellerhead Reason. The drivers supplied are less than robust which is an issue for MS Windows 7 as well as they use the native codec. I suspect that this is a USB 1.1 device: so, latency could be an issue. Without custom Asio drivers this is imminent. The ouput was clean and the unit is well built.
