The Crown PZM-30GPB is a professional Pressure Zone Microphone (PZM) designed for broadcasting, sound reinforcement, and recording. By placing the mic capsule directly against a flat boundary, it eliminates phase cancellations caused by surface reflections, capturing a clear, hemispherical sound field.
• Technology: Pressure Recording Process mounts the miniature condenser capsule in the "pressure zone" (or boundary) to provide higher sensitivity and uncolored sound.
• Frequency Response: Switchable dual-response (Flat for smooth, natural audio; Rising for added brilliance and crisp attack on percussion and pianos).
• Maximum SPL: Can handle extremely loud audio sources (up to 150 dB SPL) without distorting.
• Power Requirement: Requires 12V to 48V DC phantom power. POWER SUPPLY INCLUDED, or 24v phantom power source may be utilized.

Common Applications
• Stage & Broadcasting: Widely used on conference tables, lecterns, and theater stages.
• Music Recording: Popular for capturing grand pianos (taped to the inside of the lid), drum room overheads, and kick drums. (Note: Acrylic sheet with mic stand mount is included. Useful for drum kit overhead.)
A pair is available. See additional listing.
