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.
