Model 120 Helpinstill Grand Piano Sensor

For any size Grand Piano. Covers the entire range of the piano keyboard in three regions to insure uniform volume from every note. Our standard passive control box allows simple adjustments to the volumes of each section of the keyboard, and provides both a mic-level mono output via the XLR connector, and an instrument-level high-impedance mono output via a 1/4″ phone jack. Installs in minutes without tools or harm to the piano. This is the unit we recommend for 90% of our applications.
