A supercardioid capsule for the versatile Shure 181 mic.
The Shure BETA RPM181/S is a supercardioid capsule for the versatile Shure BETA 181 microphone. The BETA RPM181/S capsule is ideal for snare drums, acoustic instruments and any other close-miking applications.
The Shure BETA 181 (sold separately) is a multipurpose instrument microphone and can be used on a wide variety of applications including guitars, bass and drums (overheads and snares). It has a small-diaphragm design that provides superior audio with textbook polar responses in a form factor compact enough to get close to the source in the tightest conditions.
There are four different capsules available for the BETA 181 microphone: this Supercardioid (RPM181/S), as well as a Cardioid (RPM181/C), Bidirectional (RPM181/BI), Omnidirectional (RPM181/O). This makes the BETA 181 an extremely versatile and cost-effective mic that allows the user to interchange capsules according to the application. (Additional capsules sold separately).
