The Nady CM 100 ultra linear classic diaphragm electret condenser microphone is optimally designed for precise alignment applications such as room acoustics corrections. Perfect also for many recording uses, both instruments and vocals. The CM 100 is supplied with a foam windscreen (FW-1/100). This windscreen fits over the grill portion of the microphone and 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 FW-1 or other windscreen should be used whenever someone is close miked to both protect the microphone and to also eliminate popping sounds from percussive breath sounds. The CM 100 can be used in live or studio alignment applicatoins or studio recording. It must be powered by 48V phantom power (such as supplied by the optional Nady SMPS-1 phantom power supply or a mixing console/alignment device equipped with phantom power), and amplified by a microphone pre-amp (such as built into amixer, or a stand-alone unit).
