Shure UL4 UniPlex Cardioid Lavalier Microphone — XLR Connector with RPM400 (Black)
UL4 Overview
The Shure UL4 UniPlex is a professional lavalier microphone featuring a cardioid polar pattern designed specifically for spoken-word applications where isolation from surrounding noise sources is essential. Its directional pickup makes it well-suited for environments with stage noise, audience bleed, or close-proximity presenters sharing the same space. Supplied with the Shure Plex cable and XLR connector with RPM400, this configuration integrates directly into standard wired audio systems without additional adapters. Audio engineers, broadcast technicians, AV integrators, and corporate presentation specialists will find the UL4 a reliable solution for demanding speech reinforcement scenarios.
The cardioid pattern provides meaningful rejection of off-axis sound sources, giving operators greater control over gain structure and mix clarity in live and broadcast environments.
