H2 nie znam z doswiadczenia ... moze niestety.
Ale,
Nie wiem czemu piszesz o noise ratio H2 skoro nie ma takich specyfikacji od producenta - jeżeli masz linki dla takowych w H2, daj linkacza.
Dobrze wiesz, ze producenci chetnie pomijaja te fragmenty specyfikacji, ktore szkodza marketingowi
. W tym przypadku posilkowalem sie forami (testy userow):
Pierwsze:
.... I measured the recording signal to noise ratios for various sampling rates, with shorted inputs: 86dB unweighted both in 96kHz/24bit and 44.1kHz/24bit modes. In absolute terms this is fairly poor, failing even the requirements for an ideal 16 bit system (96dB SNR), but it still betters any cassette recorder and performs at the level of affordable USB or FireWire computer audio interfaces, and as such can be used for simple audio measurements to....
Drugie:
The noise floor is not spectacular, but is not too bad. With the inputs terminated in 150 ohms, the peak noise was -70 dBFS, but that improved to about -85 dBFS or better, measuring it as an A-weighted rms figure, which is how most noise is measured. While this certainly isn’t what one would expect out of the Sound Devices, it is far better than the 50-60 dB(A) that one can achieve with an analog cassette tape without Dolby.
