Hello,

I have iOne, AKG P220 (condenser) on the XLR input, phantom power ON. The level knob ('1') has to be turned *exactly* to just above 9 (if the entire range is 10) in order for the samples to be registered in the software. I tried the Studio, I tried Audacity. Any minute change in the knob position, and it either clips pretty much everything or is barely registering anything. That is to say that if I move it below 9 (say, to 8.5), the computer receives tiny samples, pretty much useless. So, essentially the knob acts like a switch, I can't really manage the level with it.

I did ask tech support about it, and they say it's normal, i.e. it was "designed to" do that. A tech in a local store, however, swears that this is not normal for audio interfaces and suggests that the preamp is faulty. I am not proficient enough in electronics to have an opinion of my own, sadly.

The question I have for you folks, does your iOne do the same? I wish I had another iOne, known to be working properly, to compare. Asking you is the next best thing, I suppose.

Can you help please?

Thank you.

I have the same problem adjusting mic levels, however I am using a dynamic mic and Audiobox iTwo. Behavior of the level knob is the same like you described. The lever is either too low or too high (clipping).
When I connect a guitar on a 1/4" instrumental input the adjusting of the level is much more continiously and easier then with a mic.
Is the device defective or it's a normal operation?

Thanks, Anton, for sharing your experience. I thought I'd get more responses by now... :roll: I did try a dynamic mic, for which I had to turn the knob all the way up to get any response at all. Yes, I can make it clip when I shout into it, otherwise it registers about -20 dB, which actually corresponds to what Presonus is saying on one of their support pages that I managed to dig out (sorry, don't have the link).

This has been discussed before:

The main problem is they are using the wrong kind of potentiometer. If this part was installed in just some of these units, all of us that bought these bad units should get a free repair :(

Do you have more information to backup this, or is this just an assumption with a very high probability?

Totally agree. That would mean a financial disaster for such cheap unit, nevertheless, fair and true.
