The Shure BETA 181/KIT Microphone Kit is a small-diaphragm side-address condenser microphone kit which includes a omnidirectional, cardioid, supercardioid, and figure-8 capsule. This multipurpose microphone kit can be used on a wide variety of applications including guitars, bass and drums!
The Shure BETA 181/KIT Microphone Kit is a side-Address condenser microphone with interchangeable capsules. A total of four different capsules (Cardioid, Supercardioid, Bi-directional, Omni-directional) are available, allowing you to interchange them according to application.
Interchangeable Capsules
The RPM181/C is a cardioid condenser capsule for the Beta 181. The RPM181/S is a super cardioid condenser capsule for the Beta 181. The RPM181/BI is a bi-directional condenser capsule for the Beta 181. The RPM181/O is a omni directional condenser capsule for the Beta 181.
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.
