Except for the lady folks who seem to START in that range. What happens in so many female voices I hear (including broadcast stations) is that high central tonality dominates to the point of overwhelming the silibant range and 600-1200 NEEDS to be seriously suppressed to let the silibants emerge. I'm not sure 6 dB is enough for them. 73, Guy. > I like to add a bit of a > "notch" in the middle (-6dB at 800 Hz) ... cutting that band helps > to reduce background noise without impacting voice quality. > > With reasonable adjustments to enhance the frequencies important for > communications (vs. some "golden ear" belief in a bandwidth more > appropriate to classical music), reducing the power wasted in the > lower octaves that do not contribute to enunciation, and 10 to 15 dB > of clipping, the K3 can more than hold it own while remaining very > clean compared to the Yaecomwood rigs that drive the PA into clipping > in order to generate ALC! > > 73, > > ...
