Hi Gianni,
I tested the TASCAM HD-P2 some time ago. The frequency response of
it's A/D section is very similar to the SoundDevices 722 recorder:

So, the poor 0.5/-20dB figure in the specifications is obviously
related to the overall (A/D and D/A) response.
In my experience, the relatively low maximum microphone gain is good
enough for sensivive microphones (25...50 mV/Pa). Note that the
specified gain figure alone does not necessarily say anything about
the absolute input sensitivity (which would also depend on the input
voltage range of the A/D converter chip). The "maximum gain" figure of
Message: 46.
Subject: 2 dB actually seems to be the difference between the maximun
(-60dBu) and minimum (-13.8 dBu) trim settings.
