The Shure Specialty to General Communications Microphone Series
WL 93 are economical omnidirectional, subminiature, lavalier, condenser microphones designed for general speech applications where a visually unobtrusive microphone is desirable. All WL93 models are supplied with a mounting block with attached tie bar, a sew-on mounting bracket, and an acoustic windscreen to minimize wind noise in outdoor applications. All WL-93 models include a cable terminated with a 4-pin mini connector which connects directly to a Shure wireless body-pack transmitter.
→ 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
