Shure R189 Mini-Shotgun Microphone Cartridge for Microflex

Available in black or white, the R189 from Shure is a highly directional mini-shotgun microphone cartridge that threads onto all Microflex® (MX) gooseneck and overhead microphones, including those used with Microflex Wireless and Microflex Complete. The narrow pickup pattern rejects ambient noise and prevents feedback in rooms with sound reinforcement, making it an ideal choice for noisy conference rooms and live presentations.
