Solve Sound Problems in Public Address, Broadcasting and Recording

Sensitive at Front
Dead at Rear

Shure Cardioids are working wonders for Sound Engineers
in every type of installation. A simple ear test quickly
tells how effectively they solve troublesome sound problems-
how greatly they improve the pick-up and reproduction of
voice and music. Shure Cardioids bring you all the advan-
tages of true uni-directional performance at low cost. They
provide smooth wide-range reproduction from 40 to 10,000
cycles over a wide angle at the front (both horizontally and
vertically) which diminishes sharply to a pronounced dead
zone at the rear (down 12-15 db at rear). You get the sound

you want, as you want it.

IN PUBLIC ADDRESS. What a difference-when you plug
a Shure Cardioid into the amplifier. You can get more volume
without feedback-cut down the pick-up of audience and
background noise-reduce reflected sound and reverbera-
tion effects 66%-and permit performers to move about more
freely. Where necessary, you can place the microphone and
loud speakers close together for better audience coverage. All
this makes it easier to set up your sound system in any loca-
tion without worrying about room acoustics or outdoor prob-
lems. You also add modern beauty to your entire sound
system. That is why Sound Engineers in all parts of the
world are replacing ordinary microphones with Shure Cardi-
oids on existing sound installations and using Cardioids on
news systems, too-in theatres, night clubs, auditoriums,
schools, churches and similarly difficult acoustic locations!

Ordinary Microphone

Shows how feedback occurs
with conventional Micro-
phones. Sound from loud-
speakers reaching the Micro-
phone directly and by reflec-
tion from walls, ceiling, and
floor, flows around the case
and into the front of the
Microphone, and is again
reproduced. Ordinary micro-
phones also pick up back-
ground and audience noise.

SIMPllFY INSTAllATION

IN BROADCASTING AND RECORDING. The Shure
Cardioid, of course, is ideal for studio work-and essential
when you take a microphone out of the studio on remote
pick-ups. The Cardioid cuts down reverberation effects-
reduces random noise pick-up-gives prominence and defini-
tion to the direct sound at the front of the microphone. In
small studios it permits you to place the microphone with
its back close to the studio wall without worrying about
troublesome reflections. This facilitates microphone place-
ment-simplifies microphone technique-improves sound
quality. When you consider its excellent performance and
comparatively low cost, you can readily understand why
more and more prominent broadcast stations and recording
studios are adopting the Cardioid as standard equipment.

THE SHURE UNIPHASE PRINCIPLE. Only the Shure
Cardioids give you all this at such surprisingly low cost! The
outstanding development of the Uniphase principle by Shure
Engineers (Shure Patents Allowed) made possible for the
first time true cardioid uni-directional performance in a single
microphone element instead of two. This eliminates the neces-
sity of matching two dissimilar units in one microphone. This
means uniformity and economy in production-and low
cost to you. Provides extra ruggedness, too.

DYNAMIC AND CRYSTAL. Shure Cardioid Microphones
are available in Uniplex Crystal and Unidyne Dynamic models
illustrated and described on the opposite page.
