AKG / Crown PZM10 Professional Flush-Mount Boundary Microphone

The PZM®-10 and PZM®-10LL, part of the Pressure Zone Microphone® line, are designed for security, surveillance, and conference-table use. Since they do not look like microphones, they are inconspicuous. Each mic's tubular housing mounts in a 25/32-inch diameter hole in a ceiling panel, wall or table.

The PZM®-10 has a mic-level output and a 3-pin XLR-type connector for easy plug-in installation. The mic requires 12 to 48 V phantom power.

Like other Pressure Zone Microphones®, the PZM®- 10 and PZM®-10LL use a miniature mic capsule mounted very near a sound-reflecting plate or boundary, in the Pressure Zone. In this zone, direct sound from the sound source combines in phase at all frequencies with reflected sound off the boundary. The benefits are many: 6 dB more sensitivity, 6 dB less noise, a wide smooth frequency response free of phase interference, excellent clarity and reach, and consistent pickup anywhere around the mic.

Frequencies below the voice range are rolled off to reduce pickup of air conditioning rumble. The high-frequency response is boosted slightly to help articulation. Because of their tailored response and PZM® construction, the PZM®-10 and PZM®-10LL will pick up conversations or other desired sounds with extra clarity and definition.

The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. The mic's humbucking transformer and steel case prevent hum pickup, even near fluorescent lights.
