Crown PZM Omnidirectioinal Boundary Microphone
Crown PZM Omnidirectional Boundary Microphone
The Crown PZM-6D Boundary Microphone is a high-performance hemispherical boundary layer microphone designed for pro recording, sound reinforcement and broadcasting applications. A pressure zone mic in a small metal housing, the PZM-6D offers hemispherical pattern for intelligible sound pickup and a switchable dual-frequency response for enhanced flexibility in mic placement and sonic character. The Crown PZM-6D Boundary Microphone has many applications, from miking full orchestras or individual musical instruments to security or teleconferencing. Each mic has a switchable dual frequency response: rising (R) or flat (F). The “rising” position adds brilliance. This makes it useful wherever a crisp attack is desired, such as on percussion, drums, or piano. The user can get a bright sound without boosting high frequencies on the recording console; the result is lower noise. The “flat” position provides a smooth, flat, high-frequency response for natural sound reproduction. The Crown PZM-6D Boundary Microphone has a smaller plate. Its low profile, unobtrusive appearance is appreciated in conference rooms, as well as on television, film and video productions. When suspended over an orchestra on a clear panel, the Crown PZM-6D Boundary Microphone practically disappears. Its miniature, permanently attached 15-foot cable also reduces visual clutter. The Crown PZM-6D Boundary Microphone has a 6-foot cable, and can be special-ordered from your Crown dealer. The output of either mic is a male 3-pin XLR-type, balanced and low impedance, which permits long cable runs without hum pickup or high-frequency loss. Like other Pressure Zone Microphones, Crown PZM-6D Boundary Microphone utilizes the Pressure Recording Process in which a miniature condenser microphone capsule is positioned very close to a sound-reflecting plate or boundary. The capsule is mounted in the “Pressure Zone” just above the boundary, a region where sound coming directly from the sound source combines in phase with sound reflected off the boundary. The benefits are excellent clarity and “reach,” a hemispherical polar pattern, uncolored off-axis response, and a wide smooth frequency response free of phase interference.
