Now, as a reward for struggling through all that, here's an

for someone to make themselves look smart: What is the queer little
blue
thing labelled '100HX-6bB' [sic] with what looks to be a blue 'pull
out
bit' slap in the middle of this board from one of my mics:

Heh heh - bB instead of dB on a circuit board?


That sort of thing happens on stuff that is almost certainly sourced
from the Land Of The Noodle - it's a bit like a recording pro
mis-spelling the word 'cardioid'!



It's a bass roll off or high pass filter if you prefer. Cardiods and
ribbons tip up the bass when used close.


:-)



Can also be used to reduce handling noise or even traffic if using
outdoors. Handling or even wind noise can cause the electronics to
overload, so rolling off the bass before the mic and amp electronics
then
restoring it at a later point can be useful. A bit like an RIAA curve.


Interesting and, I suspect, pointing me toward some hitherto 'uncharted
territory' - namely, the weird and wonderful world of
'equalisation'...??
