HOW TO CONTROL FEEDBACK
A

performer's number one enemy in using a microphone is

"feedback." This is a harsh hum, howl or squeal which oc­curs when the microphone picks up sound from the
loudspeakers, re-amplifies and rebroadcasts it over and
over again.

The key factor in the prevention of feedback is the posi­tion of the loudspeakers in relation to the microphone.
Feedback occurs if the microphone picks up sound coming

from the loudspeakers. Keep the loudspeakers as far to the
sides as possible-so they do not point toward the micro­phone. Always keep the microphone pointed toward the
performer and away from the loudspeakers. When stage
monitor loudspeakers are used, make sure they are posi-

tioned in front of the performers and face the rear of the

microphone.

If you are in a room with hard walls, floor, and ceiling,

the sound from the loudspeakers may bounce back into the

microphone and create feedback. Solve this problem by

turning down the amplifier volume control and working

closer to the microphone.

(Important Note: If you cannot solve the feedback prob-

lem with your

B

microphone, a Shure

Feedback Controller is suggested.)

BASIC POINTS FOR PROFESSIONAL
MICROPHONE TECHNIQUE

Proper microphone technique will add to the overall ef-

fectiveness with which you project yourself to your

audience. Keep the following points in mind when using

the microphone:

I.

Maintain the proper distance from the nlicrophone.
When you wish to achieve an intimate tonal quality,
get closer to the microphone and lower your voice. For
wide-open "driving" effects, raise your voice and back

from the microphone so that you do not over-

away
drive your amplifier to distortion.

2.

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

from the loudspeakers.

3.

Consider the microphone as an instrument and prac­tice your technique to enhance your performance.

YOUR SHURE MICROPHONE IS BUILT TO LAST!

Your Shure Microphone is ruggedly built and should give

you years of uninterrupted service; however, remember

that it is a sensitive
phone, or subjecting it to unnecessarily rough treatment.
Normal usage, of course. will not impair performance of
the unit. Use the protective carrying case to prevent dam­age not only when traveling, but also when storing the
n~icrophone.
