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

OPTIONAL ACCESSORIES

• Foam windscreen

• XC-10 — 10’ XLR to XLR mic cable

• XC-20 — 20’ XLR to XLR mic cable

• XC-25 — 25’ XLR to XLR mic cable

• XC-50 — 50’ XLR to XLR mic cable

• Supercardioid polar pattern for maximum feedback rejection

• Rugged die-cast body, hardened steel mesh

• Superior internal shockmounting to eliminate handling noise

• Lightweight, rugged and durable

• Operates on a single internal AA battery with no phantom power
required

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.

PRECAUTIONS AND CARE OF YOUR SPC-25

• The capsule is the heart of the condenser microphone. If it
become dirty or wet, the sound will be degraded. Never spray
any liquid on the microphone head. Always use a foam
windscreen if you talk or sing close to the microphone grill
screen.

• The microphone should never be dropped or subjected to
extreme shock. Store only in a padded case to protect it during
transport.

• Keep the microphone away from extremely high temperatures
(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.

FREQUENCY RESPONSE

• After use in a high-moisture application such as a stage
performance, wipe off the microphone with a dry cloth and
permit it to air dry. Do not store the unit in a closed space (e.g.,
a plastic bag) until all moisture has evaporated.

• The optional foam windscreen for the SPC-25 is designed
primarily to decrease bass rumble (from wind noise pickup)
during outdoor live or recording use. It is also useful in keeping
mouth spray out of the microphone head. The windscreen
should be used whenever someone is close miked to both
protect the microphone and to also eliminate “popping” sounds
from percussive breath sounds.

(Note: Be aware that the foam windscreen will slightly attenuate

the high frequency response of the microphone.)
