Omnidirectional Condenser Lavalier Microphone
General Description
Shure Model WL93 and SM93 Microphones are omnidirectional, subminiature, lavalier electret condenser microphones. Their
visually unobtrusive design and tailored frequency response make them ideal for body-worn applications in TV broadcasting,
theater, and sound reinforcement. Both the Model WL93 and the SM93 feature a small microphone element that provides full,
clear sound comparable to that of much larger microphones.
The WL93, intended for wireless use, connects directly to a Shure wireless body-pack transmitter. The SM93, intended for
wired applications, includes a preamplifier assembly for connection to three-pin professional (XLR) audio connectors. The
SM93 requires phantom power, and operates over a range of 11 to 52 Vdc, covering both DIN and IEC phantom power stan
dards.
FEATURES
Subminiature lavalier design; ideal size for theater, television broadcasting, video, film, and sound reinforcement
Small, inconspicuous mounting hardware
Full, clear sound comparable to larger microphones
Smooth extended frequency response with presence rise specially tailored for chest-worn microphone operation
Controlled low-frequency rolloff reduces low-frequency clothing and room noise
Low distortion, wide dynamic range
Uniform omnidirectional polar pattern
Preamplifier assembly (SM93) can be pocketed, strapped to the body, or clipped to belt or waistband
Wide-range phantom powering (SM93) accepts all commonly used voltages

CONNECTIONS
Connect the male, four-pin miniature connector (TA4M) at the end of the 93 microphone cable to the supplied preamplifier
(SM93) or to a Shure wireless body-pack (WL93).
NOTE: Do not connect the 93 microphone directly to a mixer without using the supplied preamplifier or body-pack.
MOUNTING THE MICROPHONE
The tie clips and mounting bracket provided with the WL93 and SM93 allow the user to wear the microphone in a variety of
ways. To achieve optimum pickup, attach the microphone to the user's chest. You can also obtain high-quality sound when the
microphone is worn in the hair, sewn into clothing, or attached to an acoustic instrument such as a guitar.
Tie Clip. A spring-loaded clasp attaches easily to a necktie, lapel, blouse, or shirt. Snap the microphone into the clip's
mounting bracket and attach the clip to an article of clothing. The dual tie clip supplied with the SM93 provides simultane
ous mounting of two microphones.
Sew-On Bracket. Sew the supplied sew-on mounting bracket directly to a garment (Figure 1). Use dark or light thread as
necessary to match the color of the bracket.
MOUNTING THE SM93 PREAMPLIFIER
Use the spring-loaded belt clip to hold the amplifier to a belt, skirt or trouser waistband, or inside pocket.
WINDSCREENS
An acoustic foam windscreen is supplied to help reduce undesirable wind noise associated with outdoor miking.
POWERING THE SM93 PREAMPLIFIER
Power the preamplifier supplied with the SM93 using any phantom supply providing 11 to 52 Vdc, such as the Shure Model
PS1A Power Supply.
SM93 PREAMPLIFIER IMPEDANCE
Use a minimum load impedance of 800 Ω or greater for maximum signal handling and minimum distortion. Load as low as 150
Ω can be used, but a reduction in output clipping level will result. Note that the power supply itself may add loading (3300 Ω in
the Shure PS1A) to the microphone.
USING OTHER PREAMPLIFIERS OR BODY-PACKS
If connecting the 93 microphone to anything OTHER than a Shure wireless body-pack or the preamplifier supplied with the
SM93, make sure it provides a regulated +5 Vdc source (40 µA minimum) at pin 2 of the microphone connector, as shown in
"MICROPHONE WIRING DIAGRAM" Figure.
