Crown's PZM (Pressure Zone Microphone) Series are omnidirectional boundary microphones. They can be placed on a large surface such as a table, floor, wall, or lectern. The Crown PZM 6RB Pressure Zone Microphone prevents phase interference from surface reflections, allowing a wide, smooth response. Microphone sensitivity is boosted 6 dB by the surface mounting.

The Crown PZM 6RB microphone lets the user optimally place microphones in the performance venue. Designed for use on flat surfaces, The Crown PZM 6RB can be placed where conventional microphones do not work well. Their wide, smooth frequency response makes them ideal for miking pianos, harps and other orchestral instruments. Their small size and low profile also make them an excellent choice for recording projects, conference rooms and security applications.
