Perfect way how to mike a grand piano – Helpinstill Grand Piano Humbucking Sensor

Miking a grand piano at live events such as philharmonic orchestra or rock show might be a challenging task.

Unlike vocals, horns or electric instruments like guitars played through amplifiers, the piano does not have a focused, single point for obvious mic placement that will enable us to hear the piano clearer. Pianos generate their considerable sound energy over a large area that effectively couples the vibrations of thin strings to the surrounding air, without any one spot ever being that loud.

Traditional usage of gradient microphone has several disadvantages like limited gain before feedback, crosstalk not only with other instruments but even with room acoustic. Moreover using more than one mike can introduce phase cancelation effect so it makes dead spots across the keyboard.

Of course, there’re other acquisition techniques like PZM – Pressure Zone Microphone or Vibration Transducer. But these still have some drawbacks.

There’s one technique that captures entire sound. It is called string sensing and operates on the same principle as an electric guitar pickup. That means natural piano sound without any chance of feedback or bleed-trough from other sound signal sources.

OteSound has bought patented Helpinstill Balanced-Line Grand Piano Humbucking Sensor that is the only string sensing pickup system currently on the market.
