so how how much sensetivity should the mic give in order to have a good s/n ratio - 10mv/a, 20mv/a ect..? does it mean that if supply enough gain, than the edirol preamp won't work at all?
BTW, if i get a hot mic (much sensetivity) an use it for the line in, will i still need a preamp? or should i also consider impedance matching?
