The Crown® PZM-30D 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.

It 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 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 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.


    •  Type: Pressure Zone Microphone. •  Transducer: Electret condenser. •  Frequency response: 20 Hz to 20 kHz. See Fig. 1. •  Polar pattern: Hemispherical when used on a floor, wall or ceiling. •  Open circuit sensitivity: 7 mV/Pa* (–43 dB re 1 volt/ Pa). •  Power sensitivity: –43 dB re 1 mW/Pa. EIA sensitivity –135 dBm. •  Impedance: 240 ohms, balanced. Recommended minimum load impedance 1000 ohms. •  Self-noise: 20 dB equivalent sound pressure level, A-weighted. •  S/N rati 74 dB at 94 dB SPL. •  Maximum Sound Pressure Level: 150 dB SPL at the microphone produces 3% THD. •  Polarity: Positive pressure on the diaphragm produces positive voltage on pin 2 with respect to pin 3 of the output connector. •  Operating voltage: Phantom power, 12 to 48 volts DC, positive voltage on pins 2 and 3 with respect to pin 1 of the output connector. •  Current drain: 1.1 mA. •  Connector: Male 3-pin XLR-type. •  Cable: Permanently attached 15-foot (4.58-m) black cable with XLRM connector. Model •  Switch: Frequency-response select switch for rising or flat response. •  Color: Black. •  Weight: 6.5 ounces (184 grams). •  Dimensions: 3 in x 2.5 in. x .375 in. (7.62 cm x 6.35 cm x .95 cm). See Fig. 3. •  Included accessories: PZM windscreen, carrying pouch. •  Optional accessories: PH-1A phantom power supply (1 channel, battery or AC-adapter powered).
