The PZM®-11 present a low-cost solution for security and surveillance applications. Mounted on a standard wall plate the PZM®-11 doesn’t look like a microphone but rather an ordinary light switch.

Like other Pressure Zone Microphones, the PZM®-11 utilize the Pressure Recording Process™ in which a miniature condenser microphone capsule is mounted very close to a sound reflecting plate or boundary. The benefits are a wide, smooth frequency response free of phase interference, excellent clarity and “ reach”, and consistent pickup anywhere around the microphone.

Intelligibility is excellent, with low frequencies below the voice range rolled off to reduce the pickup of heating, ventilation or air-conditioning rumble (HVAC noise). The high-frequency response is boosted slightly to aid clarity and articulation. Electronics on the rear of the plate offer screw terminals, eliminating the need for connectors.

The PZM®-11 has a mic-level output and is powered by 12-48 V phantom power
