• PZM® -6D is smaller, lighter, and has a permanently attached cable
PZM-6D
PZM-30D
The PZM®-30D and the PZM®-6D are Pressure Zone Microphones®. Both are designed for professional recording, sound reinforcement and broadcasting.
They have 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 PZM
®-30D is sturdy and reliable because it can be used with a rugged detachable cable. The PZM®-6D 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 PZM
®-6D practically disappears. Its miniature, permanently attached 4,6 m (15- ft.) cable also reduces visual clutter.
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, the PZM
®-30D and PZM®-6D utilize 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.
