Crown PZM-11 Boundary Microphone
The Crown PZM-11 Boundary Microphone is a pressure zone mic 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 PZM-11 is designed to look like a light switch so as not to draw attention.
The Crown PZM-11 Boundary Microphone has a mic-level output and is powered by 12-48 V phantom power. Like other Pressure Zone Microphones®, the Crown PZM-11 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.
In the Crown PZM-11 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 Crown PZM-11 Boundary 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.
