{"v":"2.0","page_type":"product","title":"The Crown PZM-11 & PZM-11LL are Pressure Zone Microphones 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 andPZM-11LL are 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. The PZM-11LL has a line-level output and can be powered by 24V AC, 12-24V DC, or 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. To phantom power the PZM-11LL, a modification will have to be made to the electronics module. A factory modified version for direct phantom power is available as the PZM-11LLS2. Like other Pressure Zone Microphones, the PZM-11and PZM-11LL utilize 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 PZM-11and 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 allows long cable runs without hum pickup or high-frequency loss. PZM-11 is Mic Level & Powered is via 12-48 volts Phantom Power. PZM-11LL is Line Level & Powered by 24VAC, 12-24VDC, or Phantom Power.","breadcrumbs":[{"label":"Home","href":"/python/html6/index.html"},{"label":"Brands","href":"/python/html6/menu_brand_index/menu_brand_index_brands_87101ba214.html"},{"label":"Crown International","href":"/python/html6/menu_brand_products/1000/41000/menu_brand_products_CrownInternational_1_291d2b2638.html"},{"label":"PZM-11","href":null}],"content":{"product":{"mpn":"PZM-11","manufacturer":"Crown International","brand":"Crown International","brand_url":"/python/html6/menu_brand_products/1000/41000/menu_brand_products_CrownInternational_1_291d2b2638.html","title":"The Crown PZM-11 & PZM-11LL are Pressure Zone Microphones designed for conference-room, security and surveillance applications.
