Small-diaphragm Sound, Side-address Convenience!

Small diaphragm condenser microphones offer incredible accuracy and imaging, which makes them indispensable for capturing acoustic instruments, cymbals, and many other sound sources in the studio. However, positioning traditional pencil-style condensers has it challenges. That's what's so great about Shure's Beta 181 ultra-compact small-diaphragm side-address condenser microphones. This super-flexible microphone fits in places that traditional pencil condensers simply don't, giving you the same tight and focused sound, plus the flexibility to position your mics exactly where you need them.

The Beta 181/BI has a bidirectional (figure-8) pickup pattern, making it perfect for advanced mic placement techniques such as Mid-Side stereo, while adding extraordinary off-axis sound rejection to its easy of positioning. What's even better is that, like all Beta 181 models, the Beta 181/BI has a switchable capsule, so you can pick up additional polar patterns to suite your needs.

Shure Beta 181/BI Small-diaphragm Side-address Condenser Microphone Features at a Glance:
  • Polar pattern: Bidirectional (figure-8)
