The Panasonic AG-MC200G Super-Directional Camera Mountable Shotgun Microphone can be used for making documentaries and reportage videos. Its super-directional pickup ensures the ambient noise and any interfering feedback is cut out. The microphone comes with a frequency range of 160 Hz to 20 kHz and a maximum sound pressure level of 127 dB. The Panasonic AG-MC200G has a three-pin XLR output and uses a standard +48V phantom power.
The signal to noise ratio (SNR) is a useful and universal way of comparing the relative amounts of signal and noise for any electronic system; high ratios will have very little visible noise whereas the opposite is true for low ratios.
