Shure RPM181/S – Supercardioid capsule for the Beta 181 microphone

Shure RPM181/S Supercardioid Polar Pattern Capsule

The Shure RPM181/S is a supercardioid replacement capsule engineered specifically for the Beta 181 side-address instrument microphone system. Designed for close-microphone applications, this capsule excels at isolating targeted sound sources while rejecting off-axis noise, making it an excellent choice for snare drums, acoustic instruments, and other high-impact or detail-critical recordings.

Featuring a tight supercardioid pickup pattern, the RPM181/S delivers focused audio capture with outstanding clarity and control in both studio and live environments. Its wide frequency response ensures accurate reproduction across the full audible spectrum, while its exceptionally high SPL handling allows it to manage loud sound sources without distortion.

The capsule integrates seamlessly with the Shure RPM181/PRE preamplifier, maintaining a compact and lightweight design of just 5.1 oz when assembled. With low self-noise, strong signal-to-noise performance, and minimal crossover distortion, the RPM181/S provides clean, natural sound with excellent low-frequency detail. This makes it a reliable and professional-grade solution for engineers seeking precision, consistency, and versatility within the modular Beta 181 microphone system.
