The Electro-Voice RE10 is a dynamic supercardioid microphone created specially for professional applications requiring a sharply controlled supercardioid directional pattern. The RE10 is similar to the Model RE15, but meets requirements where there is less need for precise unit-to-unit matching of microphones. Utilizing the major technological breakthrough of Variable-D design* (a means for deriving directionality), the RE10 features a degree of directional control so effective that frequency response is virtually independent of angular location of sound source. Like the RE15, the RE10 possesses a degree of directional control so effective that frequency response is virtually independent of location of sound source. The result is a microphone that generates little or no off-axis. (Typical cardioids provide greatest rejection in the horizontal plane when the microphone is tilted in its most natural position - 30 degrees from horizontal, as on a boom or floor stand. An easily operated "bass-tilt" switch corrects spectrum balance for boom use and other longer reach situations.
