PZM® (Pressure Zone Microphone®) series microphones are omnidirectional boundary microphones. They can be placed on a large surface such as a table, floor, wall, or lectern. PZMs prevent phase interference from surface reflections, allowing a wide, smooth response. Microphone sensitivity is boosted 6 dB by the surface mounting. Crown’s PZM series of pressure zone microphones offer serious tools for the sound reinforcement and recording professional, as well as cost-effective solutions for a variety of other needs. As the first licensed manufacturer of the Pressure Recording Process™ (the foundation of PZM technology), Crown has developed the most successful line of PZM microphones available today. Crown PZM series microphones let the user optimally place microphones in the performance venue. Designed for use on flat surfaces, PZMs can be placed where conventional microphones do not work well. Their wide, smooth frequency response makes them ideal for miking pianos, harps and other orchestral instruments. Their small size and low profile also make them an excellent choice for recording projects, conference rooms and security applications. These technical innovations, combined with numerous others, give Crown a leading edge in bringing high-quality PZM products to the market. Specifications Transducer type: Electret condenser. Frequency response (typical): 100 Hz to 20,000 Hz. Polar pattern: Hemispherical. Impedance: 75 ohms, balanced. Recommended minimum load impedance 1000 ohms. Open circuit sensitivity: 1.4V/Pa* (+3 dBV/Pa). Power sensitivity: +8 dBm/Pa*. Equivalent noise level (self-noise): 26 dB SPL typical (0 dB = .0002 dyne/cm2), A-weighted. S/N Ratio: 68 dB at 94 dB SPL. Maximum SPL: 120 dB SPL produces 3% THD. Operating voltage: 12 to 24V DC, positive voltage on red lead with respect to shield. Positive pressure on the diaphragm produces a positive voltage on white lead with respect to black lead. Current drain: 2.8 mA at 12V DC, 4.22 mA at 24V DC. Output connectors: None. Cable: 12-in., permanently attached 3-conductor shielded cable. Red: B+, White:audio+, Black: audio–, Shield: ground. Materials: Steel plate and housing. Finish: Off-white. May be painted any color; take care to first seal the opening between the capsule and boundary plate. *1 pascal = 10 dynes/cm2 = 10 microbars - 94 dB SPL.
