Featuring the WL93 lavalier microphone, QLXD14/93 combines professional features with simplified setup and operation. QLX-D delivers outstanding wireless functionality ideal for mid-size events and installations in businesses, hotels, and government offices with conferencing spaces; schools, houses of worship, and live performance spaces.

QLX-D Digital Wireless delivers defined, streamlined performance with transparent 24-bit digital audio. Combining professional features with simplified setup and operation, QLX-D offers outstanding wireless functionality for demanding live sound events and installations. Shure digital wireless technology enables QLX-D to transmit clearly detailed audio with extended, virtually flat frequency response. Designed to be highly RF spectrum efficient, QLX-D can operate more than 60 compatible channels simultaneously in a single frequency band. Automatic channel scan and IR sync make finding and assigning an open frequency quick and easy. Ethernet connection provides networked channel scanning across multiple receivers and Shure Wireless Workbench control software compatibility for advanced frequency coordination. AES-256 encryption comes standard and can be easily enabled for secure wireless transmission. QLX-D also adds Shure rechargeable power options to provide dramatic long-term cost savings and extended transmitter battery life over alkaline batteries, and battery metering that reports remaining runtime in hours and minutes. With clearly defined performance and innovation, QLX-D delivers the very latest in digital wireless technology from Shure.
