The MX184 premium supercardioid lavalier microphone brings a new level of sophistication to personal voice reproduction. Like all Microflex family microphones, this lavalier uses an interchangeable condenser cartridge, meaning there will always be a lavalier to suit your application. Wide dynamic range and frequency response for accurate sound reproduction. Interchangeable cartridges, that provide an optimal choice for each application. Rotatable tie-clip, that pivots in 90 degree increments for placement flexibility. Supplied snap-fit foam windscreen, that controls breath noise and stays on securely. Balanced, transformerless output for increased immunity to noise over long cable runs.
