Electro Voice ND757 Dynamic Vocal Microphone

Electro Voice ND757 Dynamic Vocal Microphone

The Electro-Voice N/D757 is a supercardioid dynamic microphone utilizing a revolutionary neodymium alloy to form the EV-exclusive N/DYM® magnet with four times the power potential of conventional microphone magnets. With a computer-optimized design, the N/DYM magnetic structure is maximized in the N/D757 to provide up to 6-dB more output sensitivity over conventional designs while the more uniform magnetic field lowers distortion during peak sound pressure levels. The large diaphragm contains 50 percent more surface area than conventional designs and is reinforced to prevent "breakup." The result is an extended high-frequency response with an open, transparent sound quality. The exceptional sensitivity of the N/D75 7 combined with the inherently low noise of a dynamic transducer insures a superior signal-to-noise ratio ready for digital recording and sampling. To further reduce noise, a highly effective hum-bucking coil is used to cancel hum from lighting and other sources. The N/D-Series design also features a unique shock mount totally surrounding the microphone element. Combined with the elastomeric Warm-Grip™ handle and windscreen bumper, this vibration-isolation system greatly reduces all forms of handling noise. An Acoustifoam™ pop filter is included to reduce both wind noise and "p-pop" breath sounds. The uniform supercardioid polar pattern of the N/D757 insures superior gain-before-feedback in live applications and better isolation in the studio-at all frequencies-compared with other directional microphones with widely varying polar characteristics.
