The AKG 3325H00010 is a boundary microphone that mounts flush to a wall plate and supplies clear, intelligible speech in places where the elements and background noise often ruin conversations. Built for permanent installation, it delivers a dependable line-level signal that feeds recorders, paging amplifiers, and security systems without the cost or complexity of an external preamp.

To survive rain, snow, and wash-down hoses, the microphone relies on a thin plastic membrane that shields the capsule. Water beads on the surface instead of entering the housing, and even if the membrane freezes, performance returns as soon as the ice melts and dries.

In real-world settings such as fast-food drive-thru lanes, outdoor ticket booths, toll plazas, and theme park entrances, low-frequency rumble from traffic can overwhelm voices. The PZM11 LL WR counters that issue with a frequency response that rolls off unnecessary lows and adds presence in the vocal range, keeping every word crisp and easy to understand for customers and staff alike.

The unit operates on any 12 to 24 volt DC supply already present in most intercom or security panels. Because the output is at line level, installers can run cable over long distances without introducing hum or signal loss, and the receiving device rarely needs additional gain.

Installation is straightforward. Screw terminals on the rear accept bare wire, and the plate fits a standard single-gang box. Once in place, the low-profile design stays out of the way and requires almost no maintenance, making it a practical choice for facilities that need reliable audio year-round.

Highlights:
  • Weather resistant membrane protects the capsule from rain and wash-downs
  • Returns to normal performance after moisture or ice dries
  • Speech focused frequency response reduces traffic rumble and boosts articulation
  • Operates on 12 to 24 V DC, matching common intercom power rails
  • Line-level output connects directly to video recorders, paging amps, or mixers
  • Hemispherical polar pattern captures voices clearly across a service window or counter
  • Fits a standard wall plate and keeps a low profile in public areas
  • Screw terminal connections simplify field wiring and service
