SUPPLIED MOUNTING ACCESSORIES
GENERAL
Shure models WL50/MC50 (omni) and WL51/MC51 (unidirectional) are subminiature, elec-
tret condenser lavalier microphones. They provide uncompromised sound quality and high
reliability with minimal visibility in sound reinforcement applications such as television broad-
casting and stage performances. Despite its small size, the microphone’s condenser ele-
ment provides full, clear and natural reproduction of speech. Each microphone is supplied
with two foam windscreens to minimize wind noise. The supplied mounting accessories con-
sist of a lapel clip, a tie clip, a pin mount, and a magnet mount, giving the user a wide variety
of options for placement.
MODEL VARIATIONS
WL50 (omni)/WL51 (uni): Intended for wireless use. Connects to Shure wireless
bodypack transmitters via a TA4F connector.
WL50X (omni)/WL51X (uni): Supplied with a 3 m (10 ft.) stripped and tinned cable for
wiring to an alternate connector.
WL50–LO: A lower sensitivity variation of the WL50, supplied with a TA4F connector.
(omnidirectional)
WL50X–LO: A lower sensitivity version of the WL50, supplied with stripped and tinned
leads. (omnidirectional)
MC50 (omni)/MC51 (uni): Intended for hardwired applications. WL50 or WL51
microphone supplied with an in-line preamplifier with a three-pin male XLR audio
connector.

WINDSCREENS
Two acoustic foam windscreens are supplied to help reduce undesirable wind noise.
EQUALIZATION CAPS
The WL50 and the MC50 omnidirectional models are each supplied with two types of equal-
ization caps for high frequency response shaping. The caps effect the response range be-
tween 5,000 and 20,000 Hz (see Figure 4), and can be distinguished by the color of their
mesh screens. The mild boost equalization cap has a very fine mesh, silver color screen,
and attenuates the natural high frequency peak of the microphone. The high boost equaliza-
tion cap has an open mesh gold color screen and does not attenuate the high frequency peak.
The WL51 and MC51 unidirectional models are supplied with the high boost equaliza-
tion cap only. The WL51 and MC51 models should never be used with the mild boost
equalization cap because the unidirectional pick-up pattern will be severely altered.
This is due to partial blocking of the front opening, and they will not perform correctly.
NOTE: For best sound quality, replace the equalization caps if they become
clogged with make-up.
USING THE MC50/MC51 WITH A MIXER
The preamplifier supplied with both the MC50 and MC51 requires phantom power ranging
from 11 to 52 Vdc. Connect the preamplifier to a mixer input with a minimum load impedance
of 800
Ω
to maximize operating headroom.
USING THE WL50/WL51 WITH OTHER BODYPACK TRANSMITTERS
If connecting the WL50/WL51 to anything OTHER than a Shure wireless bodypack, make
sure the device provides a reg5 Vdc (130
A minimum) to the red conductor. Refer
to the wiring diagrams in Figures 6 and 7.
WIRING THE WL50X/WL51X TO AN ALTERNATE CONNECTOR
Model WL50X/WL51X is supplied with a stripped and tinned cable for wiring to a variety of
connectors. Refer to the WL50X/WL51X wiring diagram in Figure 6. For additional informa-
tion on wiring the WL50X/WL51X to an alternate connector, contact Shure’s Applications De-
partment at (847) 600–8440 or 1–800–516–2525.
MOUNTING THE MICROPHONE
The WL50/WL51 and MC50/MC51 microphones come with the following
mounting accessories:
Swiveling Lapel Clip. Features a spring-loaded clasp that attaches easily to a necktie, lapel,
blouse or shirt, connected to a rotatable mounting clip. To mount, snap the microphone cable
into the clip near the neck of the microphone, then attach the clasp to an article of clothing.
Rotate the mounting clip to place the microphone at desired angle.
Dual Tie Clip. Features a spring-loaded clasp that attaches easily to a necktie or suit coat
lapel, and a clip that holds one or two microphones. To mount, snap the microphone cable(s)
into the clip near the neck of the microphone, then attach the clasp to an article of clothing.
Pin Mount. Features a translucent mounting clip with two straight pins that easily secure to
an article of clothing. To mount, slide the straight pins into clothing, then snap the microphone
cable into the mounting clip near the neck of the microphone.
Magnet Mount. Features a backplate that is worn under clothing and attaches to a magnetic
mount capable of holding one or two microphones. To mount, place the magnetic backplate
“necklace” around neck and under clothing, then align the magnet mount to the backplate and
secure it to clothing. Snap microphone cable(s) into the clip near the neck of the microphone,
and adjust the magnet mount to hold microphone at the desired angle.
WARNING: The magnet mount should not be used by persons
fitted with an implanted medical device, such as a pacemaker or
defibrillator.
