Description Technical Specs   The WL51 lavalier microphone series sets a new standard for miniature microphones. Visually unobtrusive, the WL51s provide uncompromised sound quality and high reliability with minimal visibility in sound reinforcement applications such as television broadcasting and stage performances. Despite its small size, the microphone's condenser element provides full, clear and natural reproduction of speech. Designed for applications that require minimal visibility without compromising sound quality, these microphones are available individually, as well as with the Shure UHF, UC, SC and LX Wireless Systems.
