At the heart of the system are two Random
Incidence, omnidirectional, 40 kHz High Definition Microphones™.
With a frequency response of 9 Hz to 40 kHz, the mics deliver extraordinary
impulse response and extremely short diaphragm settling times. In addition,
the microphones exhibit no proximity effect, regardless of their distance
from the piano strings or soundboard. The mics, when positioned close
to the sound source, also provide incredible gain before feedback.
In addition, there are multiple reflections
of each sound source from the soundboard, piano sides and piano lid. These
reflections, arriving from different angles, create what is known as a
“diffuse sound field.” A “random-incidence” microphone
is designed to be placed within such a diffuse sound field and pick up
sounds uniformly, whether they arrive at the front, the sides or the rear
of the microphone. The PianoMic™ System achieves much of its remarkable
performance through the use of specially designed, 40kHz random-incidence
High Definition Microphones™.
