Models WL93 and SM93 User Guide

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.

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.

SM93, WL-93 specifications

The Shure WL-93 and SM93 are premium lavalier microphones designed for professional audio applications, particularly in live performance, broadcasting, and theater. These microphones are renowned for their exceptional sound quality, durability, and versatility, making them a preferred choice for audio engineers and performers alike.

One of the standout features of the WL-93 and SM93 is their compact and discreet design. With a low-profile appearance, these microphones are easily concealable, allowing users to achieve a clean and unobtrusive look in various settings. Their miniaturized size does not compromise on performance, as both models deliver high-quality audio that captures the nuances of the human voice with clarity and precision.

The WL-93 and SM93 benefit from Shure's advanced microphone technologies. They utilize a carefully engineered electret condenser capsule that ensures a wide frequency response and exceptional transient response. This means that they can accurately reproduce vocals across a broad range of frequencies, from deep lows to sparkling highs, making them suitable for different types of speaking and singing voices.

Another significant characteristic of the WL-93 and SM93 is their omnidirectional polar pattern. This sensitivity pattern picks up sound evenly from all directions, allowing for greater flexibility in positioning and movement. This quality is particularly valuable in performance environments where the microphone might not always be perfectly aimed at the sound source.

Additionally, both models feature a low self-noise and a high maximum SPL (Sound Pressure Level), meaning they can handle loud sound sources without distortion. Their durability is also noteworthy, with a robust design that includes sweat-resistant construction for use in physically demanding environments.

The WL-93 and SM93 are compatible with a variety of wireless transmitters, further enhancing their usability in wireless applications. This flexibility makes them ideal for use in theater productions, public speaking engagements, or any scenario where mobility is essential.

In summary, the Shure WL-93 and SM93 lavalier microphones stand out due to their compact design, advanced microphone technologies, omnidirectional characteristics, and robust performance. They are trusted tools for professionals seeking reliable and high-fidelity sound reproduction in various applications.
