The Shure Beta 181/C Cardioid Microphone is a precision-engineered ultra-compact, small-diaphragm side-address condenser mic with cardioid capsule, designed for discreet placement and control in live and studio environments.
The Shure Beta 181/C Cardioid Microphone is a versatile condenser mic with cardioid polar pattern. Featuring a cardioid capsule, the small diaphragm design provides superior audio with consistent, textbook polar response in a form factor small enough to get close to the source in the tightest conditions. This Shure Beta 181 is a multipurpose instrument microphone and can be used on a wide variety of applications including guitars, bass and drums (overheads and snares). A total of four different capsules (Cardioid, Supercardioid, Bi-directional, Omni-directional) are available, allowing you to interchange them according to application.
Interchangable Capsule Options
The RPM181/C is a cardioid condenser capsule for the Shure Beta 181/C. The RPM181/S is a super cardioid condenser capsule for the Shure Beta 181/S. The RPM181/BI is a bi-directional condenser capsule for the Shure Beta 181/BI. The RPM181/O is a omni directional condenser capsule for the Shure Beta 181/O.
Applications for the Different Capsules
The cardioid capsule is best suited to overheads, piano and acoustic instruments. You can also use the cardioid capsule for M/S stereo micing (in conjunction with another microphone with a bi-directional capsule). The supercardioid capsule is best suited to snare, toms, acoustic instruments and other forms of close distance micing. The omni-directional capsule could be used for choirs, orchestras and ambient recording applications. Lastly, the Bi-directional capsule can be used for mono overheads, or for the recording of two instruments simultaneously on one channel.
