PZM Series Hemispherical Boundary Mic with Line Level Output

The CROWN PZM®-10LL, part of the Pressure Zone Microphone®line, is designed for security, surveillance, and conference-table use. Because it does not look like a microphone, it is inconspicuous. It easily mounts into tables, walls or ceilings.

Like other Pressure Zone Microphones®, the CROWN PZM®-10LL uses a miniature mic capsule mounted close to 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. The CROWN PZM®-10LL will pick up conversations or other desired sounds with extra clarity and definition.
