PZM Series

PZM (Pressure Zone Microphone) Series 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 PZM Series 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.

PZM-10 A low-profile microphone featuring a cylindrical design for ceiling, wall or tabletop installations. Intelligibility is excellent, with low frequencies below the voice range rolled off to reduce the pickup of HVAC rumble. XLR connector, phantom powered.


PZM-10LL Same as the PZM-10 but line-level output. Pigtail output, powered by 12-14V DC (not phantom power).


PZM-11 This low-cost microphone mounts on a standard wall plate. The PZM-11 resembles a light switch rather than a microphone. Intelligibility is excellent, with low frequencies below the voice range rolled off to reduce the pickup of HVAC rumble. Electronics on the rear of the plate offer screw terminals, eliminating the need for connectors. Powering is via 12-48 volts phantom power.
PZM-11LL Same as the PZM-11, except that the PZM-11LL features line-level output and is powered by 24VAC, 12-24VDC, or phantom power.
PZM-11LLWR A weather-resistant model designed for outdoor use. A plastic membrane inside the microphone protects the microphone capsule from water damage. The mic mounts in a standard electrical outlet box and has screw-terminal connections. Applications include fast-food restaurants, outdoor intercoms, toll booths, bridges, theme park security and home automation. Powering is by 12-24V AC or DC. PZM-11LLWRS1 (available on special order) is powered by phantom power.


PZM-20R Perfect for permanent flush-mounting in conference tables, lecterns, pulpits, walls, you name it. A hemispherical pickup pattern, rising high-frequency response and low-frequency roll-off makes the PZM-20R a great choice for clear speech pickup. It also mounts in shallow cavities or a standard electrical wall box and can be powered directly from phantom power via screw terminals. White version (PZM-20RW) also available.


PZM-30D In the PZM-30D, a switchable dual-frequency response provides a "rising" position that adds brilliance and articulation, while the "flat" position maintains a smooth and natural high-frequency response. The built-in XLR connector accepts a rugged cable. Phantom powered.
PZM-6D A smaller plate makes the PZM-6D more inconspicuous than the PZM-30D, while performance is the same. Ideal for mounting on clear panels overhead or on a piano lid. The microphone offers switchable dual-frequency "rising" or "flat" response. Miniaturized electronics found in the PZM-6D's XLR-type connector housing are attached to the mic via a 12-foot mini cable. Model PZM-6DS2 has a 6-foot mini cable, and can be custom ordered from your Crown dealer.
PZM-185 Budget model ideal for applications such as conferences, group discussions, interviews, broadcast, home video production, lectures, and recordings. XLR connector on 8-foot mini cable, battery or phantom powered.
