  • Pristine sound with the lid up or down

  • Quick and simple set up

From $2999

The PianoMic™ System was designed to revolutionize piano miking and achieve an incredible improvement in piano sound for live and recording applications with no mic stands or booms. There is more gain before feedback, significantly less leakage from surrounding instruments and the same pristine sound quality with the piano lid either up or down. 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.

  • Cannot be seen from outside of the piano (needs no stands or mic booms)
  • Superb sound with the piano lid either up or down
  • Virtually no leakage from sounds outside the piano
  • Incredible gain before feedback
  • Recording studios can now record piano with other instruments in the same room
  • Handles sound pressure levels up to 148dB
  • Quick, Simple and Easy Setup
  • 40kHz Random Incidence Omnis
  • Hear the full range of the piano including the high and low strings with no hot spots
  • The telescoping bar allows the PianoMic™ to be quickly and easily installed in nearly all grand pianos and to place the microphones close to or away from the dampers and get the exact sound desired

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™.

“I can’t think of a product that makes miking a closed lid grand piano easier or that yields a more satisfying audio result.”



“Working with these mics I noticed an instant difference in our piano sound, and the musicians on stage noticed a huge change in their in-ear monitoring system. Not only was the bleed from the other instruments significantly lessened, but even with the lid fully closed the sound retained its natural character without sounding boxy like a boundary mic on a closed lid.”

“The PianoMic™ sits inside the piano and provides an excellent sound and plenty of gain before feedback with either the piano lid up or down.”


The ease of installation is huge. The PM40’s ability to really capture the true nature of the piano is without equal.

Andrew McMahon, Pianist, Jack's Mannequin

Live sound reinforcement on a piano has always been a challenge because there is always so much noise onstage and a lot of noise rolling off the P.A. back onto the stage. Once we started using the PM40, we found we were able to run with the volumes we wanted to run at; the tone was amazing and it sounded like a piano. We didn’t have to work to get it to sound that way–you just put the mic in the piano and go.

A lovely sounding microphone that maintains its integrity whether the piano is fully open, on a short stick or fully closed. This has helped maintain a level of consistency for the show in any situation we have found ourselves in. Be that indoors, outdoors or accompanied by other instruments.

The PM40 has taken our live piano sound, which was already pretty darn good, to new levels of accuracy and realism.
