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.

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 Versadyne 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:

1.

Maintain the proper distance from the microphone.
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
away from the microphone so that you do not over­drive 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 instrument. Avoid dropping the micro-

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

microphone.

MICROPHONE CHECK-LIST

1.

Check microphone impedance-is it correct for the
amplifier input being used?

2.

Check microphone cable connectors to mixer and
amplifier-are they tightly plugged in?

3.

Check microphone, amplifier and/or mixer.
a. Are they turned on?
b. Are volume controls turned up?

IF THE MICROPHONE DOES NOT WORK

Check the above list.

If

the microphone still does not ap­pear to be operating, have the microphone and cable
checked by your Shure Professional Entertainer Products
Dealer, or write Service Department, Shure Brothers, Inc.
