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 particularly 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!
Acoustic Guitar
The sound of the acoustic guitar is very weak. Therefore, it is necessary
in many cases to boost effectively the loudness of this instrument in
relation to other instruments. Microphone placement depends primarily
on the kind of guitar played and the playing technique used.
Gut and nylon strings produce few harmonics. Bass is radiated mainly
through the sound hole, treble by the top. Direct the C 535 EB toward a
point on an imaginary line through the bridge, on the lower half of the
body. Steel strings produce more overtones than gut or nylon strings.
Direct the C 535 EB toward the sound hole rather than the top. Working
distance should be about 8 inches depending, however, on the playing
technique employed by the musician. Changing microphone orientation
and/or distance will change the tone reproduced. Since it is necessary
to place the microphone close to the instrument, the bass response will
be exaggerated. This proximity effect may be compensated for by
setting the mode switch to –14 dB .
Bass boost may also be avoided by directing the C 535 EB toward fret
no. 14, approximately where the neck joints the body.
Steel-string guitars with built-in pickups inevitably produce a rather flat
tone because magnetic pickups work well only in the midrange.
Because of the radiation characteristics of acoustic guitars – high
frequency components are radiated by the strings themselves, low
frequencies being radiated through the sound hole – a well-balanced
sound can be achieved by using an additional microphone.
