The Crown PZM-30D Boundary Microphone is a pressure zone microphone designed for professional recording, sound reinforcement and broadcasting. Featuring hemispherical polar pattern for intelligible pickup of sound from any direction, the PZM-30D's pressure zone microphone technology prevents sound coloration from surface reflections.

The Crown PZM-30D Boundary Microphone's capsule is mounted in the pressure zone, an area where direct sound and reflected sound are in phase, which provides a 6dB higher sensitivity. Two selectable frequency responses (flat/rising) provide greater flexibility in mic placement and sonic character. The rising position of the frequency switch adds brilliance and a crisp attack on percussion, drums, or piano.

The Crown PZM-30D comes in a very rugged, low-profile, metal housing with detachable cable that makes it sturdy and reliable for heavy duty applications.

    Love PZM's

    As long-time user of PZM's (the inexpensive RadioShack Realistic variety), I wanted to get a "real" (pun intended) one, i.e. the Crown that the RSR was modeled after. It doesn't disappoint, especially as it has the "rising" (top-end boost) switch... I use it on high-hats, utilizing it's natural bass rejection (when not mounted on a largish flat surface). I also use it whenever I don't want out-of-phase sound (PZM design is such that there is no phase-cancellation). Great for capturing audio that sounds just like the human ear perceives it. Fantastic for sample and environmental recording. The only issue I have is that the plate is made from some kind of ABS-type plastic, whereas my good ol' RSR models were solid steel... a sign of the times, I'm afraid. One star less for this! Otherwise, highly recommended

What We Think


The Crown PZM-30D is one of our favorite microphones to have in the studio toolkit. Why? It's really versatile and doesn't get in anyone's way. In a more traditional studio, taping this PZM to the control room window produces one of the best drum room sounds you can imagine. Trying to record piano in the midst of an orchestra or a loud band performance on stage? Tape the PZM under the inside of the lid about dead-center and facing the hammers; done. Recording brass and Woodwinds and need to capture the "glue" to help blend the close mics on them together? The PZM taped to plexi gobos will get you covered. These mics are excellent at picking up the sound of the studio and the stage. They're a must have in the realm of musical theatre and can really help in a number of other ways to bring fantastic acoustic performances to life in your recordings. We cannot recommend this microphone highly enough.
