Clarinet
The C 535 EB is perfectly suited for miking up the clarinet. The flat fre-
quency response with a slight treble boost of approximately 2 dB is
ideal for reproducing the sound spectrum of this instrument. Frequency
components between 800 Hz and 3 kHz are radiated exclusively from
the keys. At higher frequencies, radiation shifts toward the bell. Fre-
quencies above 5 kHz are radiated through the bell only. In order to
attain a well-balanced tone, mount the C 535 EB on a floor stand
(e.g. AKG St 200) and aim it at the conical portion of the clarinet,
directing it roughly toward the lowest key.
Flute
Most of the flute sound is radiated in the blowing direction of the player.
With frequencies higher than 3 kHz, preferred radiation shifts to the
right, toward the end of the flute body. When miking up the flute, the
position of the microphone depends primarily on which kind of music is
performed. Depending on the desired tone color, the C 535 EB may be
placed one to two inches, or 4 to 8 inches in front of the performerOs
lips. It is advisable to blow to the side of the microphone, in order to
avoid excessive wind noise. With extremely short working distances, it
is best to blow below the microphone.
During the actual performance, the position of the playerOs lips relative
to the microphone should, if possible, remain unchanged. If it is
necessary to capture the high frequency components above 3 kHz,
too, use an additional microphone, e.g. an AKG D 224 two-way
microphone.
Trumpet
As opposed to other instruments, microphone placement for trumpets
is easy because of the instrumentOs radiation pattern: up to about
500 Hz the sound is evenly distributed in all directions. Midrange fre-
quencies are radiated through the bell over a large angle in the playing
direction, the angle narrowing with rising frequency. Above 5 kHz the
radiation angle is about 30!. Mount the C 535 EB on a floor stand and
place it one to two feet away from the instrument, at an acute angle with
it. Thus, the trumpet player will not blow directly into the microphone so
as to avoid wind noise, above all at high sound levels.
Reduce the microphone level via the mode switch (position �14 dB flat),
in order to prevent microphone overloading and distortion during
passages of wide dynamic range.
