yes it was clipping when gain was set at 0 dB, but not much, only a few dB.
This was the signal when gain was set at 0 dB (just before gain was set negative)
My test only clipped a little bit, but this was about the hottest signal I managed to produce.
BayTaper:
That's pretty interesting though. It's almost like it can pad it a little before it runs out of headroom. Strange. More tests might unlock some more clues...
Llorean:
One thing you could do is make a recording of something that clips at 0 gain, then make another recording of the same thing at negative something, then at negative something further, and see if all three clip, and if they do, at the same point.
This should tell you if lowering into the negatives can or cannot prevent clipping (if it's at a different point in each one, then you may just need to lower it further in the negatives than it seems like, maybe a bug of some sort in the peakmeter / clip detection output).

Hi guys
I never tried the AGC patch, but anxiously awaits it beeing committed.
For all I know, it's a fact that there's NO WAY to by any digital means save a signal from clipping if it's clipping BEFORE the analog->digital conversion (ADC)....
Could there be some built in steady digital gain raise AFTER the digital gain change?
What's the resolution before the dig. gain ch.? 16 bit? 20?
Is there a reduction stage from 20 bit to 16?
(As far as I know the H1x0 has a possibility to work with 20 bit sound in some stage.)
Maybe I should go to sleep...

My thoughts exactly, which is why I'm thinking negative gain makes no sense under any conditions, I just can't think of any reason why you'd use it?
