The M3 condenser microphone is designed for the sound engineer on the go, from the stationary or mobile recording studio to the most improvised location. The M3 is extremely versatile: it can be powered with the typical 48 volt voltage or via a simple 9 volt battery. It has an adjustable high pass filter to cut annoying low frequencies and a three-stage pad to be able to attenuate sound sources with high pressures, as needed. The M3 offers a virtually linear frequency response over the entire audible range and a cardioid polar pattern for use in high-end shooting or live performance of vocals or acoustic instruments. The M3 has a convenient switch for off and a LED for battery status. Its metal casing is resistant to any type of mechanical stress.
