These Electrovoice N/D 257 Microphones are used but in good condition.
The Electro-Voice N/D257 is a cardioid dynamic microphone utilizing a revolutionary neodymium alloy to form the EV-exclusive N/DY® magenta with four time the power potential of conventional microphone magnets. With a computer-optimized design, the N/DYM magnet structure provides unprecedented sensitivity 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 "break-up." The result is an extended high-frequency response with n open, transparent sound quality.
The exceptional sensitivity of the N/D257 combined with the inherently low noise of a dynamic transducer insures a superior signal-to-noise ratio ready for digital recording and sampling.
The N/D-Series design also features a unique shock mount totally surrounding the microphone element. Combined with the elec Warm-Grip™ handle and windscreen bumper, this vibration-isolation system greatly reduces all forms of handling noise. An Acousticfoam™ pop filter is included to reduce both wind noise and "p-pop" breath sounds.
The uniform cardioid polar pattern of the N/D/257 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.
