[. . . ] CBM 40 Condenser Boundary Microphone USER GUIDE Thanks for purchasing the Nady CBM 40 Boundary Microphone!This microphone is a wide-range back electret condenser with a cardioid polar pattern. [. . . ] Although designed primarily for high quality far field pickup of audio, such as for use with choirs and stage plays, the Nady CBM 40 can also be used in many creative applications. For example, wrapped in a blanket to deaden vibrations, it is a very effective kick drum mic when placed inside the kick drum. 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 CBM 40) are specially designed to accept only signals from audio sources in front of the mic element. Thus, the half cardioid pattern of the CBM 40 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 CBM 40 in all live performance miking applications. Of course, when using this mic in far field audio pickup applications, extra care must be taken to lessen feedback. 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 CBM 40 · The microphone should never be dropped or subjected to extreme shock. · 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.
