To answer an earlier question, I used this at a fairly standard rock-pub show alongside a H4. Check the levels beforehand to make sure I had headroom (the live meters are great!) but there was still brickwalling on the H1 but not the H4 (the H1 was a bit closer to stage, which may be the reason - can't be sure now). So yeah, the recording level being after the ADC is a bit... useless here. I'd be glad to be told it was a misconfiguration on my part, though, if anyone else has tried one of these.
The recording level isn't after the ADC. A while ago in another thread on this forum there was a link to a thread on a different forum where the H1 was put through some analysis, I'm 99% sure the conclusion was that a recording level of 15-20 ish (I forget the exact number) was 0 gain. Anything below that is digital attenuation, and everything above up to 100 is internal pre-amp gain. Again, I forget the total amount of gain availible... 30-40 dB ish I think.
Considering the recording Level control is the only adjustment of levels (On the H2 you have a separate 3-step gain control, in addition to the post-ADC recording level - I will concede that this is a ridiculous design), then it cannot be post-ADC on the H1 because then there would be zero way to control the pre-amp gain. Which, considering that the input jack is both Line In and Mic In, is impossible.
If your recording was brickwalled it's because the internal mics were overloaded. I'd never use the internal mics of a sub $100 recorder in
any situation unless absolutely necessary (never mind a high SPL situation). Even then, I'd assume it was going to turn out junk.
IIRC, the same 'analysis thread' indicated that the pre-amp gain between 20 and 36 was (relatively) noisy, but after 37 there's a sudden drop off in the noise level, and it's pretty clean from then up.
I own a H1 - I would never use the internal mics. In a real pinch, I would be willing to use the internal pre-amp. What I bought it for, however, was for use with an external pre-amp. As a Line In, ADC & Bit Bucket I see nothing wrong with it at all. I can't imagine that a decent external mic & pre will sound significantly worse going Line In on the H1 compared to Line In the more expensive recorders, and for such a low price, I can deal with flimsy build quality.
