Description

This is a Pressure Zone Microphone designed for professional recording, sound reinforcement and broadcasting. It has many applications, from miking full orchestras or individual musical instruments to security or teleconferencing. This 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. These sturdy microphones are especially reliable because they can be used with a rugged detachable cable. The output 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 utilizes the Pressure Recording Process in which a miniature condenser microphone 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 a wide, smooth frequency response free of phase interference, with excellent clarity and reach, a hemispherical polar pattern, and uncolored off-axis response.

Features

  • Pressure Zone Microphone design prevents coloration from surface sound reflections
  • Choice of fl at response or rising high frequency response
  • PZM-30D uses a rugged detachable cable.
