Hi John!
In his "self-noise" debate: Now when I hear your recordings again - after
getting acquainted with the NT1A, - I think I hear a hiss which does not
come from the mic.
It could be atmospheric noise (leaves, grass in very minor wind) but it
sounds electronic. Is it the PMD670 or something else?
Or is this what the NT1A sounds like when it is cold?
Which temperature did you have?
I hear it also on the Robin recording. Same "hiss".
Klas.
