The PZM11 LL WR is a professional weather-resistant boundary layer microphone designed for fast-food restaurants, outdoor intercoms, toll booths, and more. 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 normal 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.
The PZM11 LL WR is a weather-resistant Pressure Zone Microphone® with a balanced, line-level output. A plastic membrane inside the microphone protects the mic capsule from water damage. The mic mounts in a standard electrical outlet box. Applications include fast-food restaurants, outdoor intercoms, toll booths, bridges, theme park security, home automation, and so on.
The microphone can be plugged directly into a VCR line input - no costly mic preamp is needed. Output (via screw terminals) can be balanced or unbalanced. Powering is by 12-24V ACor DC. The unit can be factory-set for phantom powering by special order.
In the PZM11LLWR, frequencies below the voice range are rolled off to reduce traffic rumble. The high-frequency response is boosted to help articulation. Because of its tailored response and PZM construction, the PZM11 LLWR will pick up conversations or other desired sounds with extra clarity.
The unit is "weather resistant", which means:
- The microphone will work during and after rainfall.
- The mic's frequency response will change temporarily if the membrane gets wet, but will return to normal when dry.
- If water freezes on the membrane, the mic's frequency response will change, but will return to normal when the ice melts and the membrane dries.
- High-pressure water sprays directly on the membrane (through the louvered wall plate) may damage the membrane.
- The microphone is not designed to be submerged.

About Boundary Microphones at Sound Productions
Optimize your audio with Sound Productions’ assortment of boundary microphones! A boundary microphone (sometimes called a “pressure zone microphone”) is comprised of one or more capsules built into a microphone that mounts on a flat surface such as a table, desk, wall, or ceiling. The low-profile design of most boundary mics makes them easy to place in a range of environments without taking up too much space, while wired and wireless options of different models give you the flexibility to place or reposition the mic as space allows.
A great choice for situations where you have more than one sound source you want to capture, boundary microphones are ideal for professional audio setups in businesses, such as board rooms, conference rooms, and office spaces. For instance, a boundary mic makes communication easier in group meetings where multiple people are collaborating. Boundary microphones work well for any multi-use environment where versatile miking is key.
