Description
The AKG PZM11 LL WR is a weather-resistant Pressure Zone Microphone with a balanced line-level output, for fast-food restaurants, outdoor intercoms, toll booths, bridges, theme park security and home automation. A plastic membrane inside protects the capsule from water, and the microphone mounts in a standard electrical outlet box behind a louvered wall plate.
It keeps working during and after rain. If the membrane gets wet or iced over, the response changes for a while and returns to normal once it dries. The line-level output plugs straight into a recorder line input with no microphone preamp, and the screw-terminal output can be balanced or unbalanced. It runs on 12 to 24 V AC or DC. Keep high-pressure water sprays off the membrane, and do not submerge the microphone.
