I got mine this afternoon. Nice little recorder. PLASTIC tripod mount though (H2's was metal)...
I did some EIN noise tests on it to start me off.
* NB I assumed that the H2n's gain range is 0 to 39dB with no part of the range set as "digital attenuation" (as on the H1 and the Sony M10).
LEVEL GAIN (dB) EIN
0 0.0 -99.1
1 3.9 -100.0
2 7.8 -100.2
3 11.7 -107.7
4 15.6 -108.0
5 19.5 -114.5
6 23.4 -114.4
7 27.3 -114.8
8 31.2 -114.4
9 35.1 -113.9
10 39.0 -114.0
I've done a few such tests of a few recorders I've had in my possession (one or two very briefly) and here's a plot:
My numbers seem to coincide with
other measurements out there and for the gain range where I tend to record (lowish i.e. 10-20dB) it would appear that the H2n and M10 are close. In the higher gain ranges the M10 is clearly ahead.
In any case, I think we can safely say that Zoom have fixed the noisy mic input compared with the H2
