GENERAL
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 standards.

broadcasting, video, film, and sound reinforcement

VARIATIONS
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 simultaneous 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.
