Shure WL93

Omnidirectional Condenser Lavalier Microphone

Shure WL93 Microphone is an omnidirectional, subminiature, lavalier electret condenser microphones. Its visually unobtrusive design and tailored frequency response makes it ideal for body-worn applications in TV broadcasting, theater, and sound reinforcement. The WL93 features 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. 

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

Connect the male, four-pin miniature connector (TA4M) at the end of the 93 microphone cable to the wireless body-pack (WL93).

CONNECTIONS

NOTE: Do not connect the 93 microphone directly to a mixer without using the supplied body-pack.

MOUNTING THE MICROPHONE

The tie clips and mounting bracket provided with the WL93 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.
• 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.

SEW-ON MOUNTING

WINDSCREENS

An acoustic foam windscreen is supplied to help reduce undesirable wind noise associated with outdoor miking.

USING OTHER BODY-PACKS

If connecting the 93 microphone to anything OTHER than a Shure wireless body-pack, 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.
