Electro Voice ND408A Supercardioid Dynamic Microphone

Electro Voice ND408A Dynamic Microphone

The Electro-Voice N/D408A 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/D408A to provide 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/D408A 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. N/DYM® Series II microphones feature Dyna Damp™ , an advanced vibration-isolation material. DynaDamp™ is a unique foamed elastomer, specifically formulated for vibration control. DynaDamp™ forms an advanced-technology vibration-isolation system which dramatically reduces all forms of vibration transmitted noise for the most demanding situations. The N/DYM® Series II pop filter incorporated a special molded retainer which insures optimum placement of the Acoustifoam™ filter material, for maximum rejection of both wind noise and vocal P-pops. The retainer makes the pop filter an integral part of the microphone's removable upper grille assembly, allowing easy cleaning for continued top performance. The uniform supercardioid polar pattern of the N/D408A 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.
