About Shure RPM181/S

How can you enhance your audio recording experience The answer lies in the Shure RPM181/S Supercardioid Polar Pattern Capsule. This high-quality, durable capsule is one of four interchangeable options designed specifically for Shure's renowned Beta 181 side-address instrument microphone.

Engineered with a supercardioid polar pattern, this innovative capsule excels in reducing background noise and focusing on the sound source. This makes it an ideal choice for recording applications where clarity and focus are paramount, from close-miking in live performance settings to capturing the nuanced tones of snare drums and acoustic instruments.

The Shure RPM181/S features a secure locking ring, ensuring a reliable connection with the Shure RPM181/PRE preamp. Despite its compact design, weighing a mere 5.1 oz, it can get close to any sound source, even in the most confined conditions.

Boasting a wide frequency response of 20 to 20,000 Hz and high SPL handling, this capsule delivers exceptional low-frequency reproduction and performs with minimal crossover distortion. This results in a microphone with remarkable sound quality and versatility.

Constructed with a hardened steel mesh grille, the RPM181/S resists denting, wear, and abuse, ensuring its longevity. The diaphragm's professional design provides consistent, textbook-like polar responses, further enhancing the audio quality.

In summary, the Shure RPM181/S Supercardioid Polar Pattern Capsule is a reliable, professional-grade tool designed to elevate your audio recording and live sound applications.
