USING YOUR SPC-25
Depending on the application, the SPC-25 can either be handheld
or mounted on a microphone stand with a standard mic clip.
Be aware of the proximity effect (an increase in bass response)
when the mic is placed close to the mouth or instrument. This may
or may not be desirable. Experimenting with the position of the
mic with respect to the audio source will ensure the optimum
results you are seeking in any given application. Also, never place
your hand over the balIscreen of the mic during use, as this can
degrade the performance.
If the microphone is placed too near a speaker, an unpleasant
howling effect (acoustic feedback) may occur. Although all
microphones are prone to feedback to some extent, those with a
unidirectional polar pattern (such as the SPC-25) are specially
designed to accept only signals from the audio source directly in
front of the mic cartridge. Thus, the cardioid pattern of the SPC-25
ensures that it will deliver only the desired audio in front of the
mic, rejecting the unwanted audio from the rear, even in noisy
ambient conditions with high sound pressure levels from the PA
and monitor speakers. This means that feedback will be greatly
minimized with the SPC-25 in all live performance miking
applications.
Some useful ways in which to totally eliminate annoying feedback
include: experimenting with mic positions with respect to the
speakers, decreasing speaker volume (whenever possible), and
adjusting the equalization of the mic audio with the mixer.
