Series Subminiature Lavalier Microphones
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.
