| Electro Voice ND468 Instrument Drum Microphone
The
Electro-Voice N/D468, part of a new generation of N/DYM ® microphones, is
specifically designed to accurately capture the sound of horns, acoustic and
electric guitars, and the percussive energy of drums in both live performance
and studio recording. The N/D468 is a member of a family of microphones
manufactured to enhance sonic smoothness, improve gain-before-feedback, and
provide more consistent performance with greater durability than earlier
generations of N/DYM ® microphones. EV's microphone designers created a smooth,
extended response with an open "top end" to reproduce instrumental sounds with
natural acoustic accuracy. The N/D468's reduced size and exclusive pivoting yoke
gives you maximum mechanical versatility on any in-strument. The N/D468 is the
musician's choice for a microphone with unsurpassed mechanical flexibility and
studio-quality acoustics.
Features
- Designed specifically for musical instruments
- Accurate response, even in high sound pressure level (SPL) applications
- Flexible mechanical design for optimum positioning
- Supercardioid pattern for exceptional acoustic isolation and feedback
rejection
Characteristic of all N/DYM® microphones is the outstanding
neodymium-iron-boron magnetic structure. This structure provides greater
sensitivity for exceptional signal-to-noise ratio and improved recording
quality. Combining the N/DYM® magnetic structure with a large, reinforced
diaphragm results in a transducer manifesting a warm, open and transparent sound
quality normally found in studio-quality microphones. The N/D468 also includes a
highly effective humbucking coil that reduces hum interference from lighting and
other electrical power sources.
N/DYM ® microphones feature EV's AcoustiDYM™ shock-mount system. This unique
vibration isolating system works as a multistage device. At low frequencies, a
rear sound wave cancels the diaphragm motion while, at high frequencies, the
specially designed rubber shock mount isolates the transducer from motion.
Combined with the windscreen bumper, the shock mount forms an advanced
technology, vibration isolating system that dramatically reduces all forms of
handling noise for the most demanding situations.
To ensure superior gain-before-feedback in live performance and acoustic
isolation in recording studio environments, the N/D468 is constructed with a
supercardioid polar pattern. The supercardioid pattern yields greater rejection
and acoustic isolation to off-axis sounds than the typical heart-shaped cardioid
pattern. For enhanced clarity, the polar response is also unusually uniform with
frequency. The impact of the supercardioid polar design is to reduce the
likelihood of feedback in live performance conditions, particularly with typical
monitor speaker placements.
The N/D468 pop filter's unique design utilizes a specially processed
Acoustifoam™ filter to minimize wind noise and vocal Ppops. This design makes
the pop filter an integral part of the microphone's removable front grille
assembly, allowing easy cleaning for continued top performance.
OPERATION
The N/D468's low-frequency response varies with the
distance of the sound source to the microphone. This is known as "proximity
effect." Maximum bass response is produced in "close-up" use with the microphone
1/4 inch from the sound source. Minimal bass response is experienced at
distances greater than 24 inches. By working closer to the microphone, the
instrument will sound more robust. The pivoting yoke designed for the N/D468
allows this type of versatile microphone placement.
"Close miking" will also reduce the potential for feedback from a PA sound
system. This benefit is in addition to the feedback-reducing supercardioid polar
pattern. When close-talked, the substantial bass boost provides an increase in
overall microphone output level. The mixer gain may be proportionately reduced,
resulting in a reduction of the system's sensitivity to feedback caused by sound
entering the microphone from the loudspeakers.
The dynamic element of the N/D468 will provide reliable operation in extreme
temperature, humidity and other adverse conditions that would render typical
condenser microphones useless. These N/D468 features will provide years of
trouble-free operation.
EV is famous throughout the industry for high quality and robust microphones
as used in studios, on stage, TV and broadcasting. Cardiline®, RE-Series,
Variable-D® are all well-known industry terms. Most of EVLs microphones are
low-impedance enabling long cable runs without RFI problems. By the way, it was
an EV mic which amplified Neil Armstrong's famous words on his arrival on the
moon's surface in 1969.
