Affordable Piano Amplification

Ensembles need to amplify pianos as they are quieter than other instruments, but the standard processes for amplifying pianos have two major problems. Microphones are an impractical method to amplify a piano's notes as they pick up unwanted noise in the form of reflections and ambient sounds. Currently other pickup system on the market have a steep price of $700.  With such a large price tag it can prohibitively expensive for enthusiast or a high school band.  

The Affordable Piano Amplification team has developed a system where sensors are placed on the soundboard of the piano and slid under the strings and cast iron plate. Wires connect the sensors to the amplification circuit, which is placed outside of the piano and outputs the resultant signal to a ¼” jack amplifier.
