Crown PZM11LLS2

Crown PZM11LLS2 Crown PZM11LLS2 Description: The Crown PZM-11LL 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 outstanding intelligibility, the PZM-11LL is designed to look like a light switch so as not to draw attention. The PZM-11LL has a line-level output and can be powered by 12-48V phantom power. Since the PZM-11LL has a high output, it can be plugged directly into a VCR line input - no costly mic preamp is needed. Like other Pressure Zone Microphones, the PZM-11LL 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, outstanding clarity and "reach", and consistant pickup anywhere around the microphone. In the PZM-11LL, 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 permits long cable runs without hum pickup or high-frequency loss.
