True - I was just trying to correct your 1.2k, which while hardly a
typo was certainly a slip of the decimal point.
No - that's the input impedance of a Neve desk - one of the classic
designs. Others too. More modern ones may be higher.
One more thing - the Neve mic pre has a pretty poor noise performance.
At -128dBu equivalent at the input, that is about 6dB above pure
thermal noise. That is 4 or 5 dB more noise than they should be
achieving.
Please do your sums properly Don before making gaffes like that !
