Tri-element Hanging Ceiling Microphone


The M3 is an innovative, tri-element hanging microphone system designed for
applications where aesthetics, sound quality, and ease of installation are critical.
The M3 is an ideal audio capture solution for video conferencing, distance learning,
courtroom activities, and surgical procedures. It can also be used for ambient room
miking and surveillance.
The M3 incorporates three phase coherent hypercardioid capsules with tailored
frequency responses optimized for speech intelligibility. This is accomplished by
minimizing frequencies caused by noise, vibration, paper shuffling, keyboard strokes,
fans, and heating/air conditioning. Low noise preamp circuitry is employed for
highest possible signal to noise and studio quality sound. A high-quality silicone
jacketed microphone cable ensures a balanced, shielded signal and a very clean look.
Electronics above the ceiling are housed within a plenum rated junction box and
cable connections are made via an RJ45 connector embedded within a proprietary
brass housing for an airtight seal.
The M3 connects to the input of a mixer or dsp console via a breakout cable
(provided). The breakout cable consists of a female RJ45 connector that terminates
in either three terminal blocks or XLR connectors (optional). A variety of optional
shielded CAT7 cable lengths (from plenum rated junction box to break out cable) are
Installing the M3 requires drilling just one 5/8-inch hole in the ceiling, with no
additional tools needed. The M3 mounting hardware easily adjusts the cable hanging
height up to four feet from the ceiling surface without removing ceiling tiles. A wire
safety cable provides additional seismic restraint.
