causing wind and pop noise, and vowels determining the timbre of
a voice by certain formants (predominant frequency bands).
The compass of the human voice extends from about 90 Hz to
around 10 kHz (including fundamentals and harmonics). The reason
why the C535 EB is particularly suited for vocalist use is that it is
the first condenser microphone to offer the required robustness
and insensitivity to exication by structure-borne noise. Another
important feature is the four-position mode switch recessed in the
microphone shaft. It allows the user to adjust the microphone to
the specific situation.
1) The sensitivity may be changed from about 7 mV/Pa, which
is typical of condenser microphones, to a value 14 dB lower
(about 1/5th). Thus, the microphone C535 EB may be connec-
ted to such devices as are designed to accept dynamic
microphones.
2) A so-called low-cut filter serves to reduce low frequency noise
(like rumble, floor noise etc.) below 100 Hz with a slope of
about 12 dB/octave.
3) A rolloff filter compensates the proximity effect (low frequency
boost when the microphone is closer than one foot to the
sound source) typically experienced with single diaphragm
systems. The elastic suspension of the microphone system
eliminates unwanted handling noise. The built-in wind and
pop screen inside the wiremesh front grille will suppress par-
ticularly accentuated explosives to such an extent as to avoid
overloading the sound system in the low frequency region.
Practice and experiment to find out how to use this high quality
sound transducer to the best effect. Find out how you can actively
change the sound by singing directly into the microphone or to the
side of it, by holding it close to your mouth or a bit farther away and
practice to create your own sound!
