Piano microphone system

Piano Mic PM40

Specifications PM40The PianoMic™ has quickly become the microphone system of choice for live performance, recording studios and churches. Live piano performances on stage or in churches enjoy the best piano sound ever with incredible gain before feedback and no mic stands or booms. Recording studios can now record piano in the same room with other instruments with minimal leakage. The telescoping bar allows the PianoMic™ to be quickly and easily installed in nearly all grand pianos.

The PMVM1 Touch-Fastner Mount is designed to mount the PM40 PianoMic™ electronics box around piano legs and other structures.

The PM40 provides pristine sound quality regardless of whether the piano lid is up or down. At the heart of the system are two Random Incidence, omnidirectional, 40 kHz High Definition Microphones™. With a frequency response of 4 Hz to 40 kHz, the mics deliver extraordinary impulse response and extremely short diaphragm setting 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.

Place the microphones inside the piano shell, 3 to 6 inches above the piano strings, to isolate the piano’s sound from sounds outside the instrument and to prevent piano sound leakage. You can use the PM40T’s adjustable, telescoping tube, which is supported by the sides of the piano case, to place the microphones close to or away from the dampers and get the exact sound desired.

PianoMic Random Incidence Mics

The innovative PianoMic™ System required the design of unique high definition microphones. Virtually all microphones used for recording and sound reinforcement are “free field” microphones, designed to pick up sounds in front of them. In contrast, the microphones in the PianoMic™ System are actually placed within the sound field of the piano, where sound is coming at the microphones from multiple sources and multiple directions. Each string is a separate sound source and the soundboard is also a sound source. 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™.
