Thanks Raimund.
Yes, you are right, I would very much like to "generalize" some
understanding of digital recorders.
Example: A client of mine (reporter) had fallen in love with the
sound and use of the old Sennheiser MD21. He had tried it with LS10,
a Tascam and a Zoom recorder, but got far too much noise. However, it
worked just fine with the Sony D50. And this was NOT a matter of 4-5
db, caused by EIN differences.
Why?
90% of all Sony D10 users get a audibly lower self noise when using
the Telinga Clip-On's, compared to the built in mics. But some 10% doesn't.
Why?
The by far noisiest recording that I have heard with the Telinga SSM,
were made with a Nagra digital recorder.
Why?
I have a long list of such "mysteries" that I would very much like to
have explained, at least on a basic level. So would my clients. If
these "why's" cannot be straightened out at all, please say so and I
will rest my case.
Klas.
