The Crown® PZM®-11 is a Pressure Zone Microphone® designed for conference-room, security and surveillance applications. Each can be mounted in the ceiling or wall in a standard electrical outlet box. Providing excellent intelligibility, the PZM-11 is designed to look like a light switch so as not to draw attention.
The PZM-11 has a mic-level output and is powered by 12-48V phantom power.
Like other Pressure Zone Microphones, the PZM-11 utilizes the Pressure Recording Process in which a miniature condenser microphone capsule is mounted very close to a sound-refl ecting 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 refl ected off the boundary. The benefits are a wide, smooth frequency response free of phase interference, excellent clarity and "reach," and consistent pickup anywhere around the microphone.
In the PZM-11, low frequencies below the voice range are rolled off to reduce pickup of air-conditioning rumble. The high-frequency response is boosted slightly to aid clarity and articulation.
The microphone connector is a row of screw terminals for easy installation. The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss.
