  • Description

    The Crown PZM-10 part of the Pressure Zone Microphone line, is designed for security, surveillance, and conference-table use. Since they do not look like microphones, they are inconspicuous. The mic’s tubular housing mounts in a 25/32-inch diameter hole in a ceiling panel, wall or table.

    The PZM-10 has a mic-level output and a 3-pin XLR-type connector for easy plug-in installation. The mic requires 12 to 48V phantom power. Like other Pressure Zone Microphones, the PZM-10 uses a miniature mic capsule mounted very near a sound-reflecting plate or boundary, in the Pressure Zone. In this zone, direct sound from the sound source combines in phase at all frequencies with reflected sound off the boundary. The benefits are many: 6 dB more sensitivity, 6 dB less noise, a wide smooth frequency response free of phase interference, excellent clarity and “reach,” and consistent pickup anywhere around the mic.

    Frequencies below the voice range are rolled off to reduce pickup of air conditioning rumble. The high-frequency response is boosted slightly to help articulation. Because of its tailored response and PZM construction, the PZM-10 will pick up conversations or other desired sounds with extra clarity and definition.

    The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. The mic’s humbucking transformer and steel case prevent hum pickup, even near fluorescent lights.


      •  Transducer type: Electret condenser. •  Frequency response (typical): 80 Hz to 20,000 Hz. •  Polar pattern: Hemispherical. •  Impedance: 240 ohms, balanced. •  Open circuit sensitivity: 2.5 mV/Pa* (–52 dBV/Pa). •  Power sensitivity: –52 dBm/Pa •  Equivalent noise level (self-noise): 26 dB SPL typical (0 dB = .0002 dyne/cm2), A-weighted. •  S/N Rati 68 dB at 94 dB SPL. •  Maximum SPL: 120 dB SPL produces 3% THD. •  Operating voltage: 12 to 48V phantom power, positive voltage on pins 2 and 3 with respect to pin 1. •  Polarity: Positive pressure on the diaphragm produces a positive voltage on pin 2 with respect to pin 3 of output connector. •  Current drain: 400 microamperes. •  Output connectors: Male XLR type (3-pin pro audio). •  Cable: None supplied. Use 2-conductor shielded mic cable. •  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. •  Net weight: 2.6 oz. (73.6 g).
