Your selection of a Shure SUPER-PROCardioid Microphone
will contribute significantly to the professional quality of
your performance. This ball-type microphone has a super
rugged steel mesh screen with a special filter which pro-
vides protection from wind, blast and "pop" (explosive
breath sounds). This feature allows you to work as close
to the microphone as you wish, to reduce the pickup of
unwanted sounds either indoors or out-of-doors.
Your microphone helps control feedback because it is uni-
directional. Since
it picks up sound only from the front of
the microphone, audience noise and other unwanted sounds
occurring at the rear or sides of the microphone are sup-
pressed. This permits
a greater working distance from the
microphone with minimal background sound pickup. The
PESOSP also features instant usage with low- or high-
impedance microphone inputs using the line matching
transformer supplied.
(See inside for information on how to use your
Shure Microphone more effectively.)

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 oc-
curs 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 micro-
phone. 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 sopnd 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 SUPER-PROTMmicrophone, a Shure Feed-
back 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 over-
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 prac-
tice 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 dam-
age 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 microphone,
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, 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,
Shure Brothers, Inc.

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, one of them or its cable (low impedance
only) is out of phase. All cables and microphones should
be tested in this manner to insure that they are in phase
with each other.
To change the phase of a low-impedance microphone
cable, either use a Shure AlSPR Phase Reverser or inter-
change the wires connected to pins
2 and 3 of the connec-
tor. 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 microphone is supplied wired for low impedance for
connection to low-impedance microphone inputs (rated at
19 to 300 ohms). For instant change for connection to
high-impedance
(?4 in. phone jack) microphone inputs,
connect the supplied cable (or any number of additional
CS 1 CNs) to the low-impedance side of the furnished
A95FP Line Matching Transformer and plug the high-
impedance side
(% in. phone plug) into the input.
For internal impedance change, remove male plug insert
by turning slotted setscrew inward (counterclockwise).
Disconnect two-terminal impedance selection socket from
rear of male insert, and reconnect socket in reverse posi-
tion so that pin
3 of male insert is inserted in socket
terminal "H". NOTE: After following the above direc-
tions, the PESOSP with the supplied two-conductor CSlCN
cable will be suitable for connection to high-impedance
inputs using three-pin professional audio connectors. For
direct connection to 1/4 in. phone jack inputs, replace the
CSICN cable with the CS-X: 6.lm (20 ft) single-con-
ductor shielded with three-pin professional audio connector
(female) on microphone end and
'/4 in. phone plug on
equipment end.

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 same type and model of microphone
so that the group
as a whole will be "balanced."
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 micro-
phones 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.
