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 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 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 PAand monitor speakers. This means that feedback will be greatly minimized with the SPC­10 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-10
• 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.
• 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.
• To protect the mic cartridge and ensure the longest possible useful life, it is highly recommended that for vocal applica­tions, 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.
