RE38N/D Dynamic Cardioid Microphone
RE38N/D Dynamic Cardioid Microphone

field response shown is the output when the
sound source is at least 24 inches from the
microphone grille. The low frequency re-
sponse increases due to “proximity effect”
when the sound source is less than 24 inches
from the microphone. This low frequency
response will continue to increase as the
sound source moves closer to the micro-
phone. The amount of “proximity effect” in
the output of the microphone can be con-
trolled by placing the microphone at differ-
ent distances from the sound source and with
the equalization choices provided in the
RE38N/D. Positions 9 through 16 have the
same low frequency shape as the respective
positions 1 through 8, the difference being
that high end response is “bright” in posi-
tions 9 through 16.
Architects’ and Engineers’
Specifications
The microphone shall be a dynamic cardioid
type with a wide uniform frequency response
from 70 to 20,000 Hz. The microphone shall
have bass-boosting “proximity effect” when
used up close and an easy to adjust equali-
zation switch permitting the selection of 16
different frequency response adjustments.
The open circuit voltage sensitivity shall be
2.5 mV/Pascal at 1000 Hz and the power
level sensitivity shall be -53 dB at 1000 Hz
where 0 dB equals 1 mW/Pascal. The mag-
netic circuit shall be a nonwelded circuit and
employ a neodymium alloy magnet. The
transducer shall employ a hum-buck coil
with a resulting hum sensitivity of -135 dBm
at 60 Hz in a 1 millioersted field and a shield
to prevent dust and iron particles from reach-
ing the diaphragm. Rated impedance shall
be 150 ohms. Line shall be balanced to
ground and phased. Pin 2 shall have a posi-
tive voltage with reference to Pin 3 with posi-
tive pressure on the diaphragm.
The microphone shall be supplied with a
Memraflex™ grille screen, pop filter and an
exceptional shock isolation system using
DynaDamp
TM
, an advanced foam elastomer
formulated for vibration control.
Response at any angular position away from
the major axis shall be essentially similar to
the response on the major axis, except at-
tenuated uniformly at all frequencies by an
amount appropriate to that angular position.
Polar characteristics shall be sufficiently uni-
form in all planes so that it is, effectively, a
cardioid of revolution.
Case material shall be aluminum and steel.
The microphone shall have a unique pivot-
ing yoke, detented to hold a set position, and
a stand adapter, to provide a highly flexible
mounting system. The microphone shall have
a maximum height of 122 mm (4.8 in.), length
of 89 mm (3.5 in.), width of 109 mm (4.3 in.)
and a net weight of 380 grams (13.4 oz). The
finish shall be a non-reflecting satin nickel.
The microphone shall have a built-in cable
connector insert similar or equivalent to a
Switchcraft QG3M. Accessories shall in-
clude an 81715 stand adapter, carrying case
and 3/32 inch screwdriver.
The Electro-Voice RE38N/D is specified.
Limited Warranty
Electro-Voice products are guaranteed
against malfunction due to defects in mate-
rials or workmanship for a specified period,
as noted in the individual product-line
statement(s) below, or in the individual prod-
uct data sheet or owner’s manual, beginning
with the date of original purchase. If such
malfunction occurs during the specified pe-
riod, the product will be repaired or replaced
(at our option) without charge. The product
will be returned to the customer prepaid. Ex-
clusions and Limitations: The Limited
Warranty does not apply to: (a) exterior fin-
ish or appearance; (b) certain specific items
described in the individual product-line
statement(s) below, or in the individual prod-
uct data sheet or owner’s manual; (c) mal-
function resulting from use or operation of
the product other than as specified in the
product data sheet or owner’s manual; (d)
malfunction resulting from misuse or abuse
of the product; or (e) malfunction occurring
at any time after repairs have been made to
the product by anyone other than Telex Com-
munications, Inc. Service or any of its autho-
rized service representatives. Obtaining
Warranty Service: To obtain warranty ser-
vice, a customer must deliver the product,
prepaid, to Telex Communications, Inc. Ser-
vice or any of its authorized service repre-
sentatives together with proof of purchase
of the product in the form of a bill of sale or
receipted invoice. A list of authorized ser-
vice representatives is available from Telex
Communications, Inc. Service at 600 Cecil
Street, Buchanan, MI 49107 (800/234-6831
or FAX 616/695-4743). Incidental and
Consequential Damages Excluded: Prod-
uct repair or replacement and return to the
customer are the only remedies provided to
the customer. Electro-Voice shall not be li-
able for any incidental or consequential dam-
ages including, without limitation, injury to
persons or property or loss of use. Some
states do not allow the exclusion or limita-
tion of incidental or consequential damages
so the above limitation or exclusion may not
apply to you. Other Rights: This warranty
gives you specific legal rights, and you may
also have other rights which vary from state
to state.
Electro-Voice Wired Microphones are
guaranteed against malfunction from any
cause for two (2) years from the date of origi-
nal purchase. In addition, the Limited War-
ranty for the acoustic system contained in
these microphones shall apply for the life of
the product, defined as a period of ten (10)
years from the date that the manufacture of
the specific microphone has been discontin-
ued. Any and all active electronics incorpo-
rated in these microphones are guaranteed
against malfunction due to defects in mate-
rials or workmanship for a period of three
(3) years from the date of original purchase.
The Limited Warranty does not extend to
cables, cable connectors, or switches. Addi-
tional details are included in the Uniform
Limited Warranty statement.
