Audix MG18HC — Miniature Hypercardioid Gooseneck Condenser Microphone
AX-MG18HC Overview
The Audix AX-MG18HC is a professional miniature gooseneck condenser microphone from the MG Series, designed for podium, presentation, meeting, and teleconferencing environments. It features dual preamp circuitry with one circuit housed in the capsule and a second built into the XLR base, delivering an internally balanced audio path that resists hum, noise, and RF interference from cell phones and wireless GSM devices. The hypercardioid polar pattern provides tight pickup isolation, rejecting ambient noise and off-axis sources in challenging acoustic environments. This microphone is well suited for houses of worship, corporate AV installations, government facilities, and broadcast applications requiring consistent, reliable speech reinforcement.
The MG Series gooseneck form factor integrates cleanly into fixed-installation podium and lectern setups, and the internally balanced circuitry ensures signal integrity across long cable runs without requiring additional external components.
