with Cardioid Condenser Capsule
Shure - BETA 181/C
multipurpose instrument microphoneThe 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. The RPM181/C is a cardioid condenser capsule, the RPM181/S is a super cardioid condenser capsule, the RPM181/BI is a bi-directional condenser capsule, and the RPM181/O is a omni directional condenser capsule - all for the Beta 181. This Beta 181 comes with the RPM181/C cardioid condenser capsule, if you wish to - you'll need to buy any additional capsules seperately.
