Make sure you can be heard even when people may not be focused on you with AKG’s PZM11 flush-mount boundary microphone. Designed for security and surveillance applications, the PZM11 offers consistent pickup anywhere around the mic. This is great to ensure that you’ll be heard even if you aren’t speaking directly in front of the microphone.
One common problem with a mic that offers such consistent pickup is that it can capture unwanted sounds. The PZM11 combats this with low-frequency roll-off: frequencies below the voice range are rolled off, reducing the pickup of noises from heating, ventilation, or air-conditioning rumble. In addition to cutting off those low-frequency noises, the speech you want the mic to hear is improved with a slightly boosted high-frequency response. The boosted high-frequency response helps with clarity and articulation.
The PZM11 has a mic-level output and the microphone itself runs on phantom power (12-48V). Electronics on the rear of the plate provide screw terminals so there is no need for connectors.

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.
