RE20
Variable-D®
Dynamic Cardioid
Microphone
Key Features:
•
•
•
•
•
•
Favorite of broadcast show hosts and voiceover studios
Ideal for instrument recording, especially kick
drums and acoustic guitars
Studio condenser response yet no powering
required and immune to overloading
Large Acoustalloy diaphragm and low-mass
aluminum voice-coil
Dual-ported, continuously Variable-D® with
minimal proximity effect
Steel case and hum-bucking coil provide
exceptional magnetic shielding
General Description:
The Electro-Voice RE20 is a professional-quality dynamic cardioid
microphone created specially for recording, broadcast and soundreinforcement applications requiring essentially flat response over
a very wide frequency range. The wide frequency response, coupled
with excellent transient response, make the RE20 easily comparable
to the finest condenser cardioid microphones and an easily operated “bass tilt down” switch corrects spectrum balance for use in
long-reach situations or other applications where bass attenuation is
needed.
A true cardioid microphone, the RE20 offers greatest rejection at
180º off axis - directly to the rear of the microphone. Pattern control
is so consistent that the frequency response is nearly independent
of angular location of the sound source, creating virtually no off-axis
coloration, yet providing greatest possible rejection of unwanted
sounds. An integral blast and wind filter covers each acoustic opening on the RE20. In recording sessions or on stage, singers can
“close talk” the microphone, singing with their lips almost touching
the grille screen with no worry of “P-pops” or excessive sibilance.
Part of the filter also shock mounts the internal microphone element,
reducing the transfer of vibrations from external sources. The exceptional performance of the RE20 is achieved by using a large Acoustalloy diaphragm in combination with an exceptionally low-mass
aluminum voice coil. Using this diaphragm assembly, the RE20 is
capable of reproducing extremely high sound pressure levels with no
fear of the overload and distortion often experienced with phantompowered condensers. The RE20 will also continue to function flawlessly in high humidity and elevated temperatures that would seriously degrade competitive condenser microphones. A massive steel
housing and effective hum-bucking coil assure the RE20’s resistance
to magnetically induced hum and noise. This means the RE20 can
be used successfully in situations where other microphones would
experience unacceptable levels of hum and buzz.

General Description (cont’):
Polar Response:
The bass-boosting proximity effect common to most directional microphones when used close to the sound source, is eliminated in the
RE20. This is accomplished via the application of the EV-exclusive
Variable-D® technology. By controlling the effect of microphone
proximity, the RE20 can be located very close to sound sources without a loss in clarity or definition making the RE20 ideal for tight vocals and challenging instruments. It can be used inside bass drums,
on acoustic guitars, and is found in voice booths and broadcasting
studios everywhere.
Architects’ and Engineers’
Specifications:
The microphone shall be a cardioid type with integral blast filter
protecting all acoustic openings. The blast filter shall also serve as a
shock mount for the internal microphone element. The microphone
shall have a wide-range uniform frequency response from 45-18,000
Hz. An integral passive network shall be provided so that when the
filter switch is in the “on” position, low-frequency response shall tilt
down 4.5 dB from 400-100 Hz. With switch in “off” position, microphone shall be essentially “flat” from 80-6,000 Hz, with a broad 2.5
dB rise in response from 6,000-14,000 Hz, and nominally down 3 dB
at 18,000 Hz. Response below 80 Hz shall be nominally down 3 dB
at 45 Hz. Output level shall be 1.5mV/Pascal. Nominal impedance of
150 ohms. Response at any angular position away from the major
axis shall be essentially similar to the response on the major axis,
but attenuated uniformly at all frequencies by an amount appropriate
to that angular position. Attenuation at frequencies from 45-10,000
Hz (refer to major axis signal value) shall exceed 15 dB at 180° from
major axis in any plane. Attenuation above 10,000 Hz shall exceed 13
dB. Polar characteristics shall be sufficiently uniform in all planes so
that it is, effectively, a cardioid of revolution. There shall be a shield
to prevent dust and iron particles from reaching the diaphragm. The
case shall be made of steel. The microphone shall have a maximum
diameter of 54.4 mm (2.14 in.), a body diameter of 49.2 mm (1.94 in.)
and a length of 216.7 mm (8.53 in.). Finish shall be a nonreflecting
fawn beige. A stand adapter shall be supplied. The Electro-Voice
RE20 is specified.

The e 604
A clip-on classic with character
Character instead of mainstream. Close to the attack, robust, easy
to handle: the e 604 has long been a classic on the rims of tom-toms
and snares the world over. Thanks to the practical clip-on microphone
clamp, the microphone can be mounted in seconds and positioned
however you choose.
Lightly emphasized in the upper mids and highs, the e 604 provides a
forceful sound, open and clear in the lows. The snare receives a warm
to dynamic presence; woodwind instruments also receive a marked
spaciousness. This is no surprise since the sound design is based on
the legendary MD 421 microphone.
Features
• Compact dynamic microphone
• Handles extreme sound pressure levels (over 160 dB) without
distortion
• Impact-resistant fiberglass reinforced housing
• Extremely simple handling and flexible positioning
• Low sensitivity to handling noise
• Very low inherent self-noise
• Humbucking coil
• Integral stand mount

N/D868
N/DYM® Bass Drum
Microphone
Key Features:
•
Designed specifically for kick drum applications in live or studio environments
•
Optimized sensitivity for the high sound
pressure levels found in bass drum micing
•
Extended low-frequency response
•
No additional EQ required
•
Rugged steel construction for exceptional
durability
General Description:
The N/D868 is truly a top performer in any application.
Whether in a live sound or studio environment, the N/
D868 is able to handle incredibly high sound pressure
levels without distortion or overriding the input mixer.
With a response specifically designed to “kick” the N/
D868 can be used “as is”—no additional EQ required.
Electrovoice was the first to utilize the neodymium
magnet structure, and it remains at the heart of our new
N/DYM series of microphones. Experience the leader
again for the first time and hear the difference.
Operation
The low frequency response of the N/D868 microphone
varies with the distance from the sound source. Known
as “proximity effect,” maximum bass response is
produced in “close-up” use with the microphone 1/4
inch from the sound source. Normal bass response is
experienced with working distances greater than 24
inches.Working close to the microphone will produce a
more robust sound. Close up positioning of the
microphone will also reduce the potential for feedback
from the sound reinforcement system. Then, the bassboost 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.

Microphone Use and Placement
Please note that micing techniques are a matter of personal preference. These are merely guidelines to assist in the placement of the
microphone to gain optimal performance.
Usage
Optimal Placement
Kick Drum
Remove drum head and damp with a pillow or blanket. Position the mic on the
pillow or blanket a few inches in front of the drum beater. As an alternative,
position the mic on a small boom stand with the mic extended into the drum
and at a 90° angle to the drum beater.
Standard Placement & Use Guidelines
1. Always point the microphone at the desired source of sound, and away from any unwanted sources.
2.The microphone should be located close to the sound source to minimize interference from other potential sound sources.
3. Use the 3-to-1 rule when using multiple microphones. Place each microphone three times farther from other microphones as from the
desired sound source.
4. Minimize over-handling of the microphone to reduce unwanted mechanical noise.
5.Working close to the microphone will increase the bass tone and also provide increased gain-before-feedback.

Frequency Response
Polar Pattern
Output from the microphone's XLRM-type connector is low
impedance (Lo-Z) balanced. The signal appears across Pins 2 and
3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” – positive
acoustic pressure produces positive voltage at Pin 2.
Response in dB
The AT4049b is intended for use in professional applications where
remote power is available. It requires 48V DC phantom power, which
may be provided by a mixer or console, or by a separate, in-line
source such as the Audio-Technica AT8801 single-channel or
CP8506 four-channel phantom power supplies.

To avoid phase cancellation and poor sound, all mic cables must be
wired consistently: Pin 1-to-Pin 1, etc.
An integral 80 Hz hi-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The high-pass position
reduces the microphone's sensitivity to popping in close vocal use.
It also reduces the pickup of low-frequency ambient noise (such
as traffic, air-handling systems, etc.), room reverberation and
mechanically coupled vibrations.
The AT4049b consists of two modular subassemblies: an AT4900b-48
body and an AT4049b-EL head capsule (both available separately).
Additional interchangeable capsules are available in cardioid
(AT4051b-EL) and hypercardioid (AT4053b-EL).
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 110° F (43° C) for extended periods. Extremely
high humidity should also be avoided.

Studio & Stage Microphones
The Josephson Engineering C42 is an all-purpose cardioid condenser
microphone suitable for multiple recording applications including spot miking
acoustic and amplified instruments, drums and drum overheads, ensemble and
choir pickups, concert recording, sound effects and vocals. Standard C42
microphones are satin machined stainless steel for years of rugged use.
C42 electronics feature a selected discrete FET driving a fully balanced
symmetrical transformerless discrete class-A output stage. The output
impedance is low enough that very long cable runs may be used without signal
degradation. Although the microphone is specified for full P48 phantom power,
it will function with phantom power as low as 24 volts, with some limitation in
maximum SPL.
A stereo kit, the C42MP, includes a matched pair of C42 microphones in matte
black chrome finish and a protective hard shell case.

APPLICATIONS
The KSM141 produces superior results in any application requiring a high quality
microphone. Typical applications include:
•
•
•
•
•
•
•
Close miking of acoustic instruments such as piano, guitar, violins, drums, and
percussion
Overhead miking of drums and percussion instruments
Electric guitar amplifiers
Brass and woodwind instruments
Room ambience pick-up (guitar amplifier or drums)
Orchestras, choirs, wind ensembles
Low-frequency instruments such as double bass and kick drum
NOTE: Sound quality is strongly affected by microphone location and room acoustics.
To achieve the best overall sound for a particular application, it may be necessary to
experiment with microphone placement and various room treatments.

USING THE KSM141
Mounting the Microphone
To secure the KSM141 to a floor stand or boom, thread the mount onto the microphone
stand and insert the microphone into the microphone clip.
Power Requirements
This microphone requires phantom power and performs best with a 48 Vdc supply
(IEC-268-15/DIN 45 596). It can operate on voltages as low as 11 Vdc, but headroom
and sensitivity will be decreased slightly.
NOTE: Most modern mixers provide phantom power.
Cable Connections
Use a cable with XLR connectors at each end.
Load Impedance
Shure recommends a load impedance of at least 1000 Ω. When used with modern
microphone preamplifiers rated at about 2500 Ω, the KSM141 provides higher
maximum SPL capability and output clipping level. When the attenuation switch is set
to the -25 dB position, it can handle up to 164 dB SPL, and can output +15 dBV into a
load of 5000 Ω or greater.
Selecting a Polar Pattern
To select either the cardioid or omnidirectional polar pattern, rotate the knurled ring on
the microphone in either direction until you feel a detent. The image of the desired
polar pattern should be directly above the notch at the base of the ring.
NOTE: Operating the KSM141 in a non-detent position (no polar pattern selected) will
produce an unpredictable polar pattern and may adversely affect frequency response.
Cardioid. When this pattern is selected, the microphone picks up sounds
directly in front of the microphone and is least sensitive to those in back. This is the
most commonly used pattern in studio recording and live-sound applications. See
Figure 4.
Omnidirectional. Picks up sounds from all directions. This pattern is best for
picking up room ambience and for miking several sources, such as an ensemble or
multiple singers, simultaneously. The omnidirectional polar pattern exhibits no
proximity effect. See Figure 4.
WARNING: Rotating the polar pattern switch produces mechanical noise which,
when amplified, may damage the loudspeakers. Turn down any loudspeakers or
mute the microphone at the mixing console before changing the polar pattern.

Setting Low-Frequency Response
dB
A three-position switch on the KSM141 lets you adjust the low frequency response of
the microphone. The low frequency filters can be used to reduce wind noise, room
noise, or proximity effect. Refer to Figure 2.

Setting Attenuation
The attenuation switch lets you reduce the signal level by up to 25 dB without altering
frequency response. This can prevent extremely loud sounds from overloading the
microphone. Set the switch to the desired attenuation levels as follows:
0 dB - Move the switch to this position for “quiet” to “normal” sound levels.
-15 dB - Move the switch to this position when the microphone is approximately 0.75
meters (2 feet) from sound sources such as a kick drum, snare drum, or electric guitar
cabinet.
-25 dB - Move the switch to this position when the microphone is 4 inches (10 cm) or
less from extremely loud sound sources such as kick drum, snare drum, or guitar
cabinets.

he U 87 is probably the best known and
most widely used Neumann studio microphone. It is equipped with a
large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid and figure-8. These are
selectable with a switch below
the headgrille.
A 10 dB attenuation switch is
located on the rear. It enables
the microphone to handle
sound pressure levels up to
127 dB without distortion.
Furthermore, the low frequency response can be reduced to compensate for proximity effect.
Applications
The U 87 Ai condenser microphone is a large
diaphragm microphone with three polar patterns and a unique frequency and transient response characteristic.
Users recognize the microphone immediately
by its distinctive design. It is a good choice for
most general purpose applications in studios,
for broadcasting, film and television.
The U 87 Ai is used as a main microphone for
orchestra recordings, as a spot mic for single
instruments, and extensively as a vocal microphone for all types of music and speech.
Acoustic features
The U 87 Ai is addressed from the front, marked with the Neumann logo.
The frequency response of the
cardioid and figure-8 directional characteristics are very flat
for frontal sound incidence,
even in the upper frequency
range.
Features
• Variable large diaphragm
microphone
• Switchable low frequency
roll-off
• Pressure-gradient transducer
with double membrane capsule
• Switchable 10 dB preattenuation
• The studio microphone classic
• Ideal as main and as support
microphone in the most
differing recording situations
• Three directional characteristics: omni, cardioid, figure-8
The microphone can be used
very close to a sound source
without the sound becoming
unnaturally harsh.
By means of a high-pass filter
interferences through subsonic
and low frequencies are reduced remarkebly.

• For universal use
• The classical studio mic for vocalists (soloists and
background vocalists)
• Announcer’s mic for broadcasting, dubbing,
voice-over
• Overhead

Electrical features
• Note: To record instruments with very high sound
pressure levels we recommend our mics with
TLM circuitry
The letter A in the name indicates a more recent generation, as compared to the U 87 i
microphones that were built from 1967 to
1986. Modifications apply to the electronic
components of the microphone only; the capsule remained unchanged.
The present-day circuitry increases the operational headroom of the U 87 Ai by supplying
the bias voltages for the capsule through a reduced resistance. The result is a higher sensitivity of 10 dB for identical sound pressure levels, and an improved S/N ratio of 3 dB.
These are just some of the most common
applications. We recommend additional experimentation to gain maximum use from this microphone.

A switch located at the rear attenuates the sensitivity by 10 dB. When this switch is activated, the microphone accepts
sound pressure levels up to
127 dB (equivalent to a sound
pressure of 45 Pa) without distortion.
Selection of Accessories
An additional switch at the
rear allows to change the
microphone's cutoff frequency.
This reduces low frequency interference directly at the input
of the microphone amplifier.
This setting also compensates
for the unavoidable bass boost
that occurs with all pressure
gradient transducers when
they are used at close distance
(proximity effect).
The cardioid characteristic
maintains a smooth frequency
response at a distance of 30 to
40 cm, the figure-8 characteristic even at a distance of 15 to 20 cm.
