Audix M45 Overview
The white Audix M45 is a miniaturized shotgun condenser microphone designed for installation in conference rooms, lecture halls, classrooms, and other public meeting spaces. Optimized for vocal intelligibility and featuring a swivel-and-pivot base for convenient aiming and positioning, the microphone can cover an area approximately 10 to 15' wide and up to 25' deep according to the the acoustics of your room.
The M45 offers high sensitivity, an integrated preamp, immunity from RF interference, and is easy to install in a 1-1/2" hole with no additional tools required. Mic-level signal and LED control is over an RJ45 connection. An adapter is included to convert from RJ45 to an 8-conductor pluggable terminal block. For use in Dante networks, the optional Audix DN4 Enhanced Onramp for Dante | AES67 supports up to four devices and includes LED logic control.
The M45 microphone is designed, machined, assembled, and tested by Audix in Wilsonville, Oregon.
