USING YOUR SPC-10
The SPC-10 can be used with any standard mixer, powered
mixer/amplifier, or mic preamp. Using either an XLR to XLR or
XLR to 1/4” phone plug low impedance cable, connect the
female XLR end to the SPC-10 and the other end (male XLR
or 1/4” phone plug, as appropriate) to your equipment.
Depending on the application, the SPC-10 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 instru-
ment. 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 unpleas-
ant 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-10) 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-10 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-
10 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 (whenev-
er possible), and adjusting the equalization of the mic audio
with the mixer.
PRECAUTIONS AND CARE OF YOUR SPC-10
• The microphone should never be dropped or subjected to
extreme shock. Store only in a padded case to protect it dur-
ing transport.
• Keep the microphone away from extremely high tempera-
tures (above 140°F or 60°C) and humidity. Avoid leaving the
microphone in direct sunlight for long periods of time.
• When using the microphone outdoors, avoid getting it wet.
• After use in a high-moisture application such as a stage per-
formance, wipe off the microphone with a dry cloth and per-
mit it to air dry. Do not store the unit in a closed space (e.g.,
a plastic bag) until all moisture has evaporated.
• To protect the mic cartridge and ensure the longest possible
useful life, it is highly recommended that for vocal applica-
tions, an external foam windscreen be used over the ball
grille. This will prevent the buildup of saliva and perspiration
on the cartridge diaphragm, which degrades performance
and shortens the useful life of the microphone. Such a wind
“sock” will also eliminate wind noise when the mic is used in
a windy outdoor environment.
