Shure Medium Shotgun Microphone Cartridge, No Preamp

The RPM89M is a medium-length shotgun microphone capsule designed to fit modular shotgun microphone systems like the Shure VP89 and SM89. It employs a highly directional, hypercardioid (lobar) polar pattern that focuses on targeted sound sources while rejecting off‑axis noise, making it suited for broadcast, film, and field recording applications. The capsule is lightweight and compact, built from aluminum alloy for durability and consistent performance across a wide range of temperatures and humidity conditions. Its narrow pickup angle provides controlled ambience and distance reach for use in concerts, talk shows, audience response, and similar scenarios where focused capture is needed.

Key Features
• Hypercardioid, uniform polar pattern for superior off‑axis rejection designed to isolate sound sources.
• Narrow pickup angle that enhances directionality and reduces unwanted ambient sound.
• Excellent radio‑frequency (RF) immunity with low self‑noise for clean signal capture.
• Lightweight, compact aluminum alloy construction for rugged field use.
• Operates reliably across a wide range of environmental conditions.
• Typical frequency response covers roughly 50 Hz to 20 kHz, supporting natural sound reproduction.
• Sensitivity around –33.5 dBV/Pa for efficient signal pickup.
• High maximum SPL handling (up to ~132 dB) for loud sources without distortion.
