AKG PZM30 D

AKG PZM30 D High-performance hemispherical boundary layer microphone

The PZM30 D high-performance hemispherical boundary layer microphone is a Pressure Zone Microphone® designed for professional recording, sound reinforcement and broadcasting. The capsule is mounted in the “pressure zone”, an area where direct sound and reflected sound are in phase, which provides a 6dB higher sensitivity.

Two selectable frequency responses (flat/rising) provide greater flexibility in mic placement and sonic character. The rising position of the frequency switch adds brilliance and a crisp attack on percussion, drums, or piano. The PZM30 D comes in a very rugged, low-profile, metal housing with detachable cable that makes it sturdy and reliable for heavy duty applications.

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.
