This Crown PZM30D Boundary Microphone is a Pressure Zone Microphone designed for pro recording, sound reinforcement, and broadcasting. It has many applications, miking anything from full orchestras to individual instruments. Dual frequency response is switchable between rising (R) and flat (F). The R setting delivers the crisp attack needed for piano and percussion while the F setting offers smooth, flat, high-frequency response. With a frequency response of 20Hz to 20kHz and a maximum SPL of 150dB it can handle just about any sound capture chore you throw at it.
