Description
 
The PZM-6D is a Pressure Zone Microphone ideal for mounting on clear panels overhead or on a piano lid. Both are designed for professional recording, sound reinforcement and broadcasting. It 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 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 15-foot cable also reduces visual clutter.

Model PZM-6DS2 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, 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.

The PZM-30D and PZM-6D feature self-contained electronics which allows them to plug directly into a standard 12-48 VDC phantom power supply. Available from Crown is a single-channel AC/ battery phantom-power supply, model PH-1A. For special applications, you can make your own battery supply as suggested in Fig. 4.
