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
the user to change the loudness of the
P.A.
system at the
microphone location. With the control on the microphone
partially turned down (turn knob counterclockwise so that
dot on knob is at
9
o'clock position), the basic overall loud-
ness of the
P.A.
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
to the dot on the microphone
(12
o'clock position). In
many instances, minimum setting of the volume control
will reduce volume sufficiently so that the volume control
can be used
as
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 posi-
tion 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.
(Important Note:
1f you cannot solve the feedback prob-
lem with your
UNISPHERE~
A microphone, a Shure
Feedback Controller is suggested.)
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
instrunlent. Avoid dropping the microphone, 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
on?
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.
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.

PHASING
To test two microphones and/or their cables for proper
phasing, connect them to an amplifier and talk or sing into
them while holding
them three or four inches apart. The
sound from the speakers should be the same when talking
into either microphone or directly between them if they
are in phase with each other. If the sound drops drastically,
or if a dead spot is found when talking between the two
microphones, they are out of phase. All cables and micro-
phones should be tested in this manner to insure that they
are in phase with each other.
To change the phase of a microphone, the microphone
cartridge leads must be interchanged (see Figure 2). This
should be performed by your dealer, the Shure Factory
Service Department, or other qualified service personnel.
IMPEDANCE
Your Model PE585V is a high-impedance microphone.
If
cable lengths over
7.6
meters (25 feet) are required, or
if the microphone is to be connected to a low-impedance
input, it will be necessary to transform the microphone
line to low impedance. Shure Model A95 Series Line
Matching Transformers are available for use in those cases.
These transformers provide a proper impedance match
between a high-impedance microphone line and a
low-
impedance input and are supplied with various input and
output connectors.
USING MORE THAN ONE MICROPHONE
It
is often desirable for a group to use a separate micro-
phone for each individual performer. In this case, the
following points should be remembered:
1.
It is best if the microphones are individually controlled
for volume through a separate Shure microphone
mixer.
If
this is not possible, it is desirable that each
performer use the sarne type and rnodel
of
microphone
so that the group as a whole wjil1
he
"halanced."
2.
Check the placement of the microphones with relation
to loudspeakers (as previously mentioned) so that
feedback is minimized.
3.
As additional microphones are added the possibility of
feedback increases. Turn off, or down, unused microphones to help solve this problem.
SHURE FEEDBACK CONTROLLER
Lets you "tune" your sound system to the acoustics of the
room. The result is more overall sound power
without
feedback. Eight linear-motion filter controls are infinitely
variable from
0
to
12
dB cut. Below
63
Hz
and Above
8
kHz roll-off switches attenuate low and high frequencies.
Can be installed between mixer or console and amplifier
for total system control, or following each microphone as
a single-channel preamplifier with feedback control.
