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 Microphone requires 12 to 48 V phantom power. The PZM®-10LL has a line-level output from its unterminated cable. It requires 12 to 24 V DC. Like other Pressure Zone Microphones®, the PZM®- 10 and PZM®-10LL use a miniature Microphone 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 the 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, with 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.
