This quality microphone is designed for discriminating users
with the most exacting professional requirements. The rugged
"333" is highly recommended for motion-picture studios, TV
studios, radio stations, professional recording, and all other
uses where quality requirements are of the highest. The "333"
is super-cardioid, uni-directional-reduces the pickup of random
noise energy by 73Yc-prevents the pickup of moving props
and scuffling feet. The "333" Studio features the patented,
world-famous Shure "Uniphase" acoustical network system-a
field-proved standard of quality.

OMNI-DIRECTIONAL DYNAMIC M I C R O P H O N E *
The Studio "525" is a n exceptionally fine, slender microphone
of broadcast quality. It is custom-built to provide high fidelity
reproduction of voice and music. The microphone has complete
versatility and reliability for indoor and outdoor use and may
be used: (1) o n a conventional floor o r desk stand, ( 2 ) in the
hand, and (3) with the lavalier cord and belt clip assembly.
The use of high efficiency magnetic materials and specially
designed magnetic circuits has made it possible t o develop this
small microphone and still achieve maximum operating efficiency. The n~icrophoneis ruggedly built to withstand hard
usage and is unaffected by temperature and humidity variations.

MICROPHONE*
This professional quality multi-impedance microphone is widely
used for tape recording, broadcast and highest quality Public
Address use. The "300" has a specially designed anti-"PFF"
filter screen-which
eliminates pickup of distracting breath
noises. I t provides sound pickup a t the front and rear of the
microphone, but greatly reduces pickup a t the sides. One of the
outstanding features of the "300" is the fact that the microphone
can be placed a t a 73% greater distance from the performer than
is possible with omni-directional microphones. I t is ideal for
highest-quality reproduction, especially wherever multi-person
pickup is desired, yet background noise must be reduced.

SPECIFICATIONS FOR MODEL 315
vlodel 3155 shown)
This rugged high fidelity multi-impedance microphone
is recommended for fine quality, general-purpose uses.
The 315 will reproduce voice and music in a clear,
natural-tone quality, which makes it ideal for use in
auditoriums, night clubs, schools and churches. It is
similar in features and design to the Studio Model 300.
The 3 15 is used for those numerous public-address
applications where its streamlined design and striking
beauty lend dignity and prestige to any setting in
which it is used. This gradient microphone is a favorite of professional performers and educators because
it provides unusual freedom of motion on the platform
-making it possible for the user to stand at a 73y0
greater distance from the microphone than is possible
with omni-directional microphones.

The Slendynes are the most versatile fine quality probe
microphones ever developed-actually five microphones in one because of their practical design and
useful accessories. They can be used for indoor or
outdoor applications in the following manner: (1) in
the hand; (2) on a floor or desk stand; (3) hung
around the neck on a lavalier cord and clip assembly;
(4) "on-off" switch adapter; (5) "high and low" dualimpedance switch. The Slendynes are ideal for high
quality public address, theater-stage sound systems and
all recording applications where an omni-directional
microphone is desirable. These microphones are ruggedly built to withstand hard usage, and are unaffected
by temperature and humidity variations.

For many years the Unidynes have been the most
widely used microphones throughout the world. They
are specified by leading sound engineers and requested
by famed celebrities-for
those important events
where the faithfulness of sound reproduction is most
critical. And now, "The Best is Even Bettero-for the
famed Unidynes are now 41% higher in output level!
This means that the Unidynes are ideal for use with
low-gain tape recorders and low-gain P. A. systemsin addition to their famed use with highest quality
sound systems.
Models 55s and 55SW are highly recommended for
fine quality public address, theater-stage sound systems,
recording and remote broadcasting. They are also the
field-proved standards for fixed-station use in the police,
fire, transportation, forestry and commercial services.
Model 5568 is specially designed to meet the high
technical requirements of broadcast and television
studios. It will endure the heavy punishment of daily
use and abuse-will
operate at optimum efficiency
while conventional microphones are "out of service,"
due to their frequent need for maintenance and repair.
It is held within close tolerances in frequency response
and directivity. The Broadcast Unidyne is ideal for
high quality station and remote broadcasting, publicaddress, theater-stage sound systems and recording
applications. The 5568 is provided with a vibrationisolation unit of live rubber construction. This specially designed shock-mount completely eliminates
metal-to-metal contact between microphone and stand.

The perfect improvement-replacement
for carbon microphones now used in mobile communications equipment. An outstanding feature incorporated in this unit
is a TRANSISTOR AMPLIFIER, housed
within the case. It is powered by the
current available from the carbon microphone circuit. Does not require batteries
or extra power-supplies. Provides remarkable speech clarity and is free from
theagingcommon to carbon microphones
used under conditions of vibration. Recommended for mobile communications
where carbon microphones have been
in use: police, bus, trucking, taxicab,

The response characteristic of these microphones has been
tailored to meet the demands of radio communications. These
microphones are ideally suited for single-sideband broadcast.
The rising response characteristic with sharp cutoff below
300 and above 3000 cps. eliminates the need for audio filters.
These units utilize a rugged, time-proven, controlled magnetic
element, with high output equalling that of a crystal unit. The 440

The M C Series of small microphones are
specially designed for use in vacuum-tube
devices, such as small, compact hearingaids, amplifiers, transmitters, dictating
equipment-wherever
size and weight are
important factors. They also are highly
recommended for use in small transistortype devices. The M C series are metal
cased for hum protection. They are rugged
units, immune to mechanical shock, and
to varying conditions of heat and humidity.
The M C Series of microphones have also

now! a tru8zcnidirectional microphone in modern, convenient
probe design at a new low price thatmakes i t practical for
every sound system to enjoy freedom from feedback
MODEL 245
The lowest priced probe-type microphone with truly
unidirectional characteristics . . . provides exceptional
performance at moderate cost.
The Shure "Uniplex" employs the same "Uniphase"
principle found in higher priced Shure unidirectional microphones. lts wide, useful pickup angle at the front and
effective elimination of pickup atthe rear provide the ideal
solution to feedback problems in low-cost P.A. systems.
The 245 is a natural for home recording, particularly in
stereo; excellent for base-station usage, paging, and
language laboratories. The 245 is lightweight and versatile, comes complete with stand adapter to permit instant
conversion from stand to hand-held use and back again.

IN CYCLES PER SECONO
Figure A
The frequency response of the Model 245
series is from 50 to 7000 cycles per second.
(See Figure A.) The microphone response is
symmetrical about the axis with the response
down 6 db at the sides, 15 db or more at the
rear. (See Figure B.) This reduced rear response feature permits more volume without
feedback which simplifies microphone and
speaker placement and greatly improves systems using conventional ~ i e r n n h ~ n e s
