[. . . ] DM SERIES MICROPHONES DM 70 and DM 80 Drum and Instrument Microphones Congratulations on purchasing the Nady DM 70 or DM 80 Microphone! [. . . ] 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 DM-70 and DM-80) are specially designed to accept only signals from the audio source directly in front of the mic cartridge. Thus, the cardioid pattern of the DM-70/DM-80 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 DM-70/DM-80 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 FOR YOUR DM 70/DM 80 · · · · The microphone should never be dropped or subjected to extreme shock. Store only in a padded case to protect it during transport.
