The Shure WL93 is the wireless version of the omnidirectional, subminiature SM93 lavalier electret condenser microphone. The visually unobtrusive design and tailored frequency response makes it 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.
