Crown PZM11 Boundary Layer Microphone Details

Crown PZM11 Boundary Layer Microphone is a pressure Zone Microphone® designed for conference-room, security and surveillance applications. It can be mounted in the ceiling or wall in a standard electrical outlet box. Providing excellent intelligibility, the Crown PZM®-11 Boundry Layer Microphone is designed to look like a light switch so as not to draw attention. Like other Pressure Zone Microphones®, the Crown PZM®-11 Boundry Layer Microphone utilizes the Pressure Recording Process" in which a miniature condenser microphone capsule is mounted 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 a wide, smooth frequency response free of phase interference, excellent clarity and "?reach," and consistent pickup anywhere around the microphone.


Crown PZM11 Boundary Layer Microphone has a mic-level output and is powered by 12-48 V phantom power. In the Crown PZM11 Boundary Layer Microphone, low frequencies below the voice range are rolled off to reduce pickup of heating, ventilation or air-conditioning rumble (HVAC 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.
