The M40P is a bold new direction for microphones suited for piano. The M40P has been designed for piano but works equally well in other applications such as boundary layer micing (conference, stage).
The “P” version of the M40 includes two main differences from the standard M40. The M40P includes an external power supply and a transformer in the circuit.
Once again, the AMT product line stays consistent with the most natural sounding piano microphone system on the market. Mono in design, the system allows for use with a closed piano lid – the only system on the market that will allow for that. 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 M40P’s signal can be split and frequencies rolled off in a specific way to create a stereo image.
The M40P terminates to the AP 41 aluminum pre-amp with chip technology, which can be powered by phantom power or the included external power supply.
