Pro gear, of
course, uses the "hotter" signal for exactly the same reason: better
dynamic
range, better noise rejection, better S/N ratio.
Pro gear typically uses balanced signals, unlike home and car pre-amp
outputs, which COMPLETELY irradiates extraneous noise (which is necessary in
a pro environment where you typically have VERY long pre-amp runs AND all
sorts of electromagnetic interference).
"Irradiates"? Heheheh... only in a nuclear-powered system
Not all pro components have balanced I/O... most, but not all.
Balanced I/O reduces and ALMOST completely erradicates (I think that's the word
you were after) noise *induced in the wiring* (not completely, and not in all
instances - check out various stories around the 'net of church sound systems
pickup up truckers' CBs!) but have no effect on various noise floors inherent in
all electronic gear.
