The M40 has been designed for piano but works equally well in other applications such as boundary layer miking (conference, stage). Once again, the AMT product line stays consistent with the most natural sounding piano microphone system on the market. It is capable of picking up subtle passages as well as sound pressure levels up to 141dB. Its rugged construction of anodized aviation aluminum allows it to withstand high impact while being lightweight and non-corrosive. The M40's signal can be split and frequencies rolled off in a specific way to create a stereo image. The M40 comes with the AP40 aluminum pre-amp with chip technology, which can be powered by phantom power or 9-volt battery. Also comes with hard shell case.
