Shure PE585V User Manual

MODEL PE585V
UNISPHEREE

A

Your selection of a Shure UNISPHERE~ Microphone will
contribute significantly to the professional quality of your
performance. This rugged unidirectional microphone effec­tively controls feedback (that very annoying loudspeaker
"squeal") because it picks up sound only from the front
of the microphone. Unwanted audience noise or other
noises occurring at the rear of the microphone are elim­inated or suppressed. This allows you to work at signif­icantly greater distances from your microphone than with
non-directional (omnidirectional) microphones, without
picking up objectionable background sound or feedback.
The built-in volume control on the microphone permits

P.A.

the user to change the loudness of the

system at the
microphone location. With the control on the microphone
partially turned down (turn knob counterclockwise so that

dot on knob is at
ness of the

P.A.

o'clock position), the basic overall loud-

system can be adjusted by the main volume
control at the amplifier location-then the user can adjust
the volume up or down at the microphone position. Maxi­mum volume occurs when the dot on the knob is adjacent

(12

to the dot on the microphone

o'clock position). In
many instances, minimum setting of the volume control
will reduce volume sufficiently so that the volume control

can be used

an On-Off switch.

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 posi­tioned 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.

BASIC POINTS FOR PROFESSIONAL
MICROPHONE TECHNIQUE

Proper microphone technique will add to the overall ef­fectiveness 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
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.

MICROPHONE CHECK-LIST

I.

Check microphone impedance-is it correct for the

amplifier input being used?

1.

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

3.

Check microphone, amplifier and/or mixer.
a.

Are they turned

b. Are volume controls turned up?

IF THE MICROPHONE DOES NOT WORK

Check the above list. If the nlicrophone then does not

appear to be operating, check it on a spare cable.

microphone still does not appear to be operating, have the

microphone and cable checked by your
