>> Features
- Interchangeable polar pattern capsules attach to a compact preamplifier with integrated XLR connections for the ultimate in low-profile application flexibility (Each Beta 181 ships with one polar pattern capsule and one XLR preamplifier. Capsules available separately for custom flexibility.)
- Precision-engineered, compact side-address design features innovative locking ring to provide secure connection between capsule and preamplifier
- Frequency response tailored for wide dynamic range applications for use in high SPL environments
- Furnished with stand adapter, windscreen and carrying case (carrying case will securely protect up to four polar pattern capsules)

- BETA 181/C (cardioid) for drum overhead, piano, acoustic instrument applications, M/S stereo technique (paired with Beta 181/BI)
- BETA 181/S (supercardioid) for snare drum, acoustic instrument, close-miking applications
- BETA 181/O (omnidirectional) for ambient/room, instrument ensemble applications
- BETA 181/BI (bidirectional) for mono drum overhead, dual instrument sound source applications, Blumlein stereo technique (pair of Beta 181/BI)
