The Shure QLXD14/83 is a digital wireless lavalier microphone system that's part of Shure's QLX-D line of digital wireless systems. QLX-D systems deliver streamlined performance with transparent 24-bit digital audio. Combining professional features with simplified setup and operation, these systems are ideal for mid-size events and installations in businesses, hotels, government offices, schools, houses of worship, and live performance spaces.With an improved presence response promoting clear, intelligible vocal reproduction, the WL-183 lavalier's omnidirectional pattern is perfect for speakers, presenters, and performers in applications where surrounding noise is low and a natural, open reproduction is preferred. Featuring an innovative 90° rotatable tie clip for precise positioning, the microphone offers flexible placement options and comes with a snap-fit windscreen, single tie clip, and zippered bag for easy storage and transport.
