Know before you buy
The system features a telescoping bar that rests securely across the piano's frame. It is designed with protective padding to ensure it stays in place without scratching or damaging the finish of your instrument.
Yes, the PM40 is specifically engineered to provide consistent, high-quality audio regardless of whether the lid is fully open, on the short stick, or completely closed.
While omnidirectional mics are typically prone to feedback, the PM40 is designed for high gain before feedback. Its placement inside the piano allows it to capture the sound source directly, which helps isolate the piano from stage noise.
Absolutely. The system is rated to handle sound pressure levels up to 148dB, making it more than capable of capturing the full dynamic range of a grand piano without distortion.
The PM40 requires standard 48V phantom power from your mixer or audio interface. It draws 10mA of current to operate.
It is excellent for both. The wide frequency response of 9Hz to 40kHz provides the detail and accuracy required for professional studio sessions, while its ease of setup makes it a favorite for live sound engineers.
