Crown PZM Series PZM-10 - microphone

The Crown PZM-10 is designed for security, surveillance, and conference-table use. Since it does not look like microphone, it is inconspicuous. The PZM-10 has a mic-level output and a 3-pin XLR-type connector for easy plug-in installation. The PZM-10 uses 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, amazing 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 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.
