SHURE-QUALITY IS OUR FIRST CONSIDERATION

Congratulations on the purchase of your new Shure microphone! It will
serve you faithfully even in the most difficult circumstances. Because more
than 50 years of experience with microphones has taught us one thing: they
are not always used under ideal conditions. Far from it! So Shure develops,
designs, builds, and tests them for the worst conditions we can imagine.

We know they'll be flung into equipment boxes after performances. We
know they'll be called upon to function at humidity levels near 100%. We
know they'll be left in the direct rays of the midday sun for hours, waiting for
outdoor concerts to begin. Professional vocalists depend upon their
microphones much as musicians depend upon their instruments, but many
don't hesitate to throw their Shure microphones across the stage and down
on the floor-violently-as part of their performance. They never give it a se­cond thought. They know that Shure microphones shrug off abuse that would
make others fail.

Shure reliability begins during the design stage. Shure has a staff of
specialists whose sole function is to uncover any weaknesses before Shure
microphones are put into quantity production. During the testing process,
microphones are:

Heated at temperatures up to
Frozen down to
Shaken from side to

and violently
Subjected to steamy humidities-up to 100% at room temperature and

93% at
Subjected to ultraviolet rays, salt sprays, alcohol, sand, and water
And for good measure, dropped repeatedly

floors.
That is our
random are put through these same tests. Failure of any one microphone
brings production to a halt until the original design requirements are again
met.

That's why at Shure we say, quality is our first consideration. The pur­chasers of the millions of microphones bearing the name Shure during past
years, and those now buying their first Shure microphone can rely on us to
continue to follow the philosophy and policies that keep Shure microphones
working dependably-year after year after year.

Quality is our first consideration!

BASIC MICROPHONE TECHNIQUE

Good microphone technique will add to your effectiveness as a performer.
Keep the following points in mind when using your Shure Professional Enter­tainer Microphone.

1. Maintain the proper distance from the microphone. When you want a
warm, full sound, get close to the microphone and lower your voice. For a
wide open, driving sound, raise your voice and back away from the
microphone to avoid overdriving the amplifier into distortion.

2.

Don't change your distance from the microphone needlessly as this will
affect the level of sound coming from the loudspeakers.

3.

Your Shure PE Microphone is your link to the audience. Consider the
microphone an instrument and develop your technique through practice.

FEEDBACK AND UNIDIRECTIONAL MICROPHONES

A performer's worst enemy in using a microphone is "feedback". This is a

harsh hum, howl, or squeal that occurs when the microphone picks up sound
from the loudspeakers, reamplifies and rebroadcasts it over and over again.
This vicious circle results in feedback.

A

unidirectional microphone aids in preventing feedback because it rejects
sound that originates from the sides and rear. Sound pickup from the sides is
reduced by about one half, and pickup from the rear is reduced by about nine
tenths. You can demonstrate this reduction in pickup by repeating "Test one,
two" or some other convenient phrase as you rotate the microphone from
front to back.

Using unidirectional microphones close to the performer or instrument en­sures that the direct sound will be much louder than the feedback-producing
amplified sound. Because the amplifier gain can be turned up less to achieve
the desired overall loudness, the amplified sound will likely remain below the
volume that triggers feedback.

Other helps in preventing feedback are:

the sides as possible; be sure that the microphones point toward the per-

formers and away from the loudspeakers; and make certain that any stage
monitor speakers are positioned in front of the performers and face the
sensitve rear of the microphone.

keep the loudspeakers as far to

UNIDIRECTIONAL MICROPHONES, OMNIDIRECTIONAL
MICROPHONES. AND PROXIMITY EFFECT

Because of thei; usefulness in reducing the likelihood of feedback, unidirec­tional microphones are best in sound reinforcement and public address;
omnidirectional microphones are best in recording where feedback problems

When unidirectional microphones are used close to a vocalist or
strument, there is an increase in bass [low-frequency] output called proximity
effect. At a distance of about

Proximity effect can be used to improve your sound.

1.

With vocalists, it increases warmth, giving a fuller quality to the voice.

2.

With instruments, it provides a flat or boosted bass output w~thout tone
controls, simply by changing the distance between source and microphone;
and close miking provides natural isolation by minimizing bass pickup of
other instruments.

Most Shure unidirectional microphones are designed with a bass response
that provides control at low frequencies yet still allows proximity effect to be
used advantageously when desired. To employ proximity effect, you need to
hear the amplified result. Just as you practice your instrument, you

w~ll want
to practice your microphone technique to get the precise sound you want. [A
good way to hear the actual result of proximity effect is to use monitor
speakers or headphones if they are available.]

Omnidirectional microphones do not exhibit proximity effect when used
closeup. Because the response does not change with angle or distance from
the performer, an omnidirectional microphone is valuable when the sound
must stay the same for several performers positioned around the
microphone, or for a performer who moves from place to place during a play
or

~nterview. But be aware of feedback problems that may occur if omnidirec-

tional microphones are used when sound amplification is present.

CHOOSING A MICROPHONE EXTENSION CABLE

Low-impedance microphones can be used with practically unlimited lengths
of cable with no added noise or high-frequency loss. Any Shure 2-conductor
balanced cables

[e.g., C25B. C25E, C25F, C50F, C1 OOF, or C20H] can be
used as extension cables for Shure low-impedance microphones. These
cables can also be used in any required lengths or combinations between a
low-impedance microphone and the

C25G Low-to-High-Impedance Cable­Transformer or between the microphone and an A95UF Matching
Transformer.

High-impedance microphone cables are usually limited to 6.

avoid high-frequency loss or possible noise pickup. If longer cables are needed
with high-impedance microphones, use such Shure cables as the

C256,
C25E. C25F or C20H to reach the required distance. Then add the C20A to
plug into the equipment. Adjust the treble control on the equipment to com­pensate for the high-frequency
