Electro-Voice N/D267 User manual

Description
The Electro-Voice N/D267, part of a new
generation of N/DYM®microphones, is de-
signed for high-quality vocal use in live-
sound and home-recording situations. The
N/D267 is a member of a family of micro-
phones that are manufactured with refine-
ments that enhance sonic smoothness, im-
prove gain-before-feedback, and provide
more consistent performance with greater
durability than earlier generations of
N/DYM®microphones. The N/D267’s
acoustic response is tuned to achieve an ex-
tended frequency range with improved tran-
sient response, presenting clear lead and
background vocals without the need for ex-
cessive equalization. Where exceptional
vocal clarity is desired, the N/D267 is the
microphone of choice.
As in all N/DYM®microphones, the N/D267
features EV’s outstanding neodymium-iron-
boron magnetic structure to provide greater
sensitivity and an exceptional signal-to-noise
ratio. In addition, the N/DYM®magnet ge-
ometry,combinedwith a largereinforced dia-
phragm design, produces a smooth, extended
frequency response with a warm, open and
transparentsoundqualitynormallyfoundonly
in studio-quality microphones.
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. Combining
AcoustiDYM™with the elastomeric Warm-
Grip™ handle and the windscreen bumper
produces an advanced technology, vibration
isolating system which dramatically reduces
all forms of handling noise for the most de-
manding situations.
The N/D267 employs a cardioid polar pat-
tern,providing enhanced front-areasensitiv-
ity and accoustic rejection directly behind
the microphone, reducing feedback under
liveperformance conditions. This is particu-
larly useful with typical monitor speaker
placement and high sound pressure level
(SPL) requirements. Additionally, the
N/D267’s polar patterns are unusually uni-
formwith frequency,ensuring superior gain-
before-feedback in live applications and su-
perior isolation when used in the studio.
The N/D267 pop filter’s unique design uti-
lizesaspeciallyprocessedAcoustifoamTM fil-
ter to minimize wind noise and vocal P-pops.
This design makes the pop filter an integral
part of the microphone’s removable front
grille assembly, allowing easy cleaning for
continued top performance. The N/D267S
has the added feature of an easily accessible
“on/off” switch.
Operation
The N/D267’s low-frequency response var-
ies with the distance of the sound source to
the microphone. This is known as “proxim-
ity effect.” Maximum bass response is pro-
duced 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 human voice will
soundmore robust. Working the microphone
close-up will also reduce the potential for
feedbackfrom a PA sound system. Thisben-
efit is in addition to the feedback-reducing
cardioid polar pattern. When close-talked,
the substantial bass boost provides an in-
crease 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/D267 will
provide reliable operation in extreme tem-
perature, humidity and other adverse condi-
tionsthatwould render typical condenser mi-
crophones useless. These N/D267 features
will provide years of trouble-free operation.
Certified Performance
Every N/D267 is inspected by a quality
control tester and subjected to a computer-
controlled test system that verifies numer-
ousperformance parameters. After the perfor-
mance meets or exceeds our rigorous stan-
dards, the actual measured frequency re-
sponse is plotted on a "Certificate of Per-
formance"and included with the microphone.
Certified performance may vary from pub-
lished "Average Response." This certificate
guaranties that each N/D267 will perform
to exacting standards of the 100% qual-
ity assurance testing, established by EV's
design engineers.
