Here is an excellent PZM for sale. I used it for a few sessions back when I had a huge vaulted ceiling in my home studio; when I actually had enough space to have 2 such mics permanently installed... I've since moved to a smaller room and haven't used this one in a few years. It's in excellent condition and ready for many more years of service. The original carrying case is included. Thanks for looking!

MANUFACTURER'S DESCRIPTION:

The Crown® PZM®-30D is a Pressure Zone Microphone® designed for professional recording, sound reinforcement and broadcasting. It has many applications, from miking full orchestras or individual musical instruments to security or teleconferencing.

The PZM-30D has a switchable dual frequency response: rising (R) or flat (F). The “rising” position adds brilliance. This makes it useful wherever a crisp attack is desired, such as on percussion, drums, or piano. The user can get a bright sound without boosting high frequencies on the recording console; the result is lower noise.

The “flat” position provides a smooth, flat, high-frequency response for natural sound reproduction. These sturdy microphones are especially reliable because they can be used with a rugged detachable cable.

The output is a male 3-pin XLR-type, balanced and low impedance, which permits long cable runs without hum pickup or high-frequency loss. Like other Pressure Zone Microphones, the PZM-30D™ utilizes the Pressure Recording Process in which a miniature condenser microphone capsule is positioned very close to a sound-reflecting plate or boundary.

The capsule is mounted in the “Pressure Zone” just above the boundary, a region where sound coming directly from the sound source combines in phase with sound reflected off the boundary. The benefits are excellent clarity and "reach," a hemispherical polar pattern, uncolored off-axis response, and a wide smooth frequency response free of phase interference
