The white M3WHM Tri-Element Hanging Ceiling Microphone with Hard Mount from Audix is designed for ceiling installations without drop tile ceilings (dry wall). It includes the M3 tri-element hanging ceiling microphone with a 4 x 4" lid that integrates the circuitry and RJ45 output with a minimum 1.5" depth for use with an optional standard 4 x 4" electrical box (sold separately). This audio capture solution offers ease of installation and can be used for video conferencing, distance learning, courtroom activities, surgical procedures, ambient room miking, and surveillance applications.
The M3 incorporates three phase-coherent hypercardioid capsules with tailored frequency responses optimized for speech intelligibility. It minimizes frequencies caused by noise, vibration, paper shuffling, fans, and air conditioning. A shielded silicone-jacket microphone cable ensures a balanced, shielded signal and a very clean look.
