The AKG 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 the like. A plastic membrane inside the microphone protects the mic capsule from water damage. The PZM11 LL WR will work during and after rainfall. If water freezes on the membrane, the mic's frequency response will change but will return to Accessories when the ice melts and the membrane dries. The PZM11 LL WR is powered by 12V - 24V DC provides line-level output and can be plugged directly into a VCR line input without the need for a costly mic preamp.
