Shure UL4 UniPlex Cardioid Lavalier Microphone — Directional Lavalier for Professional Speech Applications
UL4 Overview
The Shure UL4 UniPlex is a professional lavalier microphone featuring a cardioid polar pattern designed specifically for spoken-word applications where directional isolation is a priority. Unlike omnidirectional lavalieres, the UL4 provides meaningful rejection of stage noise, audience sound, and nearby presenters, making it well-suited for conferences, broadcast, education environments, and live presentations. It ships with the Shure Plex cable and is available in four colors and three connector options to accommodate a wide range of wireless transmitter platforms. System integrators, broadcast engineers, and AV professionals will find the UL4 a reliable solution for demanding multi-presenter and high-ambient-noise environments.
The UniPlex cardioid design addresses a common challenge in close-proximity presentation scenarios, delivering focused voice capture while minimizing bleed from adjacent sources without requiring significant post-processing.
