Hello everybody!

That is not right. Above the frequency when the dish starts to
amplifies, it gets more and more directional.
And it has not a "wonky" frequency response, but a frequency response
of a parabol, which is a very good freq. response for certain purposes.


I also read, on and on, the advice to get a Sony machine in favor of
Olympus and Zoom if one wants to keep the noise down.

I think it is time to refresh the reasoning about recorder self
noise, mic self noise and mic output voltage.

To simplify the description of these relationships, let me make a
statement: There is not ONE modern (naturesound) microphone sold
today, which has so low output signal, that it is the recorder noise
that gets disturbing.

Which means: IF you connect a modern microphone to a modern recorder,
this microphone will provide such a powerful output signal, that it
is the microphone noise that will be disturbing.

Which means: Using the modern microphones sold today, one can ignore
the specs of recorder input noise.

Rob?? Raimund? Others? Please help explain.
