The PZM11 LL WR is a professional weather-resistant boundary layer microphone designed for fast-food restaurants, outdoor intercoms, toll booths, SOS telephones, theme-park security and more. A plastic membrane inside the microphone protects the microphone capsule from water damage. The PZM11 LL WR will work during and after rainfall. If water freezes on the membrane, the microphone's frequency response will change but will return to normal when the ice melts and the membrane dries. The PZM11 LL WR provides line-level output and can be plugged directly into a VCR line input without the need for a costly microphone preamp.
