The Shure WL51 is a miniature unidirectional (cardioid) lavalier microphone with a sensitivity and frequency response suitable for professional video and sound reinforcement applications. The cardioid polar pattern effectively eliminates signal at the off-axis sections of the microphone capsule, reducing feedback and noise. The wide frequency response of 20Hz to 20kHz results in a full, clear natural reproduction of speech. The microphone is attached to a 5 foot cable which terminates to a TA4-female connection for complete integration with compatible Shure wireless microphone transmitters.
