Barcus-Berry Planer Wave
Piano System
Barcus-Berry Inc. has developed a new
type of sensor for piano pickup problems.
It is called the Barcus-Berry planer wave
piano system.
The sensing device measures abour
2 Yz" long, 1" high and Yz" wide. It can be
installed on any piano. It also permits special effects devices like chorus, flanging
and digital delay to be used. Traditionally
there have been microphones used that
have resulred in feedback problems. This
new pickup planar wave system virtually
eliminates feedback even when the piano
lid is open at full stick. It also provides
signal isolation, such as rejection of undesired ambient noise, and it assures consistent sound quality regardless of the acoustic environmenr in which the piano is
situated.
