[. . . ] C SERIES DRUM/INSTRUMENT/ SPECIALTY-USE MICROPHONES CM 55 Clip-on Miniature Condenser Microphone Congratulations on purchasing the Nady CM 55 Microphone! [. . . ] Adjust the gooseneck to position the mic as desired close to the sound source. Be aware of the proximity effect (an increase in bass response) when the mic is placed close to the instrument. 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. If the microphone is placed too near a speaker during live stage use, 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 CM 55) are specially designed to accept only signals from the audio source directly in front of the mic cartridge. Thus, the hypercardioid pattern of the CM 55 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 P. A. This means that feedback will be greatly minimized with the CM 55 in all live performance miking applications. The hypercardioid pattern of the CM 55 also ensures optimum isolation of the instrument miked from the other instruments in the mix.
