A cardioid capsule for the versatile Shure 181 mic.
The Shure BETA 181/C is a cardioid capsule for the versatile Shure BETA 181 microphone. The RPM181/C is ideal for drum overhead, piano, acoustic instruments, and M/S stereo recording (paired with the Shure BETA 181/BI)
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 is the Cardioid (RPM181/C) version. There are also Supercardioid (RPM181/S), Bidirectional (RPM181/BI) and Omnidirectional (RPM181/O) versions (additional capsules sold separately). This makes the BETA 181 an extremely versatile and cost-effective mic that allows the user to interchange capsules according to the application.
