AudioBox ITwo : Excellent quality mobile stereo audio interface with a little glitch

When you want a simple audio interface that can be used to create pro class mono/stereo recording, with portability as a prime focus, this is the one. As a bonus it is also very reasonably priced!

Thechnically it is almost superb, the preamps are absolutely fantastic and of top notch pro quality, the playback D/A stage is also very good and transparent.

But it also has little design or production glitsch: the preamp pots appear to produce a big gain difference at a point when they are almost turned up all the way. This way the last gain change is not very refined and can bring some trouble when a high gain is needed. I estimate that there is a sudden 10 dB gain difference at some point.

This was a bit disappointing to find out. I expected some more perfection of PreSonus.

Then the iOS app sofware is having some annoying bugs and is missing some important features. But that is all fixable...

This is unfortunately not the case with the gain pots, that is how it is.

But regarding the portability and connections: Great!

I use a powerbank of 11000 mAh to power the interface and that goes on for hours and hours, so the interface must be very power economic.

It can also be used as a simple standalone headphone amplifier, or a mic/instrument preamplifier.

So in all a very versatile unit and despite the gain pot problem a very good main interface in a simple audio setup with outstanding dual channel mobile recording features.
