Shure R189 Mini-Shotgun Mic Cartridge — Black
R189 Overview
The Shure R189 is a lobar mini-shotgun microphone cartridge engineered for use with the full range of Microflex (MX) gooseneck and overhead microphones, including those deployed in Microflex Wireless and Microflex Complete systems. Its highly directional pickup pattern is purpose-built to reject off-axis ambient noise and minimize feedback in rooms with active sound reinforcement. This makes the R189 a practical solution for noisy conference environments, boardrooms, houses of worship, and live presentation settings. System integrators and AV professionals will find it a reliable upgrade or replacement cartridge across the Microflex platform.
The R189 threads directly onto compatible MX microphone bodies, enabling a straightforward cartridge swap without additional hardware or adapters.
