Shure MX391/C Microflex Boundary Cardioid Microphone

The Shure Microflex Boundary MX391 Cardioid Boundary Microphone is designed to deliver clear and intelligible speech capture for installed conferencing applications. Its low profile boundary design allows for discreet placement while maintaining consistent vocal pickup across meeting spaces.

This microphone features a flat frequency response across the vocal range for natural and uncolored sound reproduction. The cardioid pickup pattern helps focus on desired sound sources while reducing ambient room noise, making it ideal for boardrooms, classrooms, and fixed installation environments.

Built for professional installations, the MX391 uses a balanced transformerless output for increased immunity to noise over long cable runs. The included cable and separate preamplifier support reliable integration into permanent audio systems where speech clarity and consistency are critical.
