Shure BETA 181/BI Figure 8 Compact Side-Address Instrument Microphone

The Shure BETA 181/BI is a condenser microphone with a side-address form factor and an interchangeable capsule system that lets you swap polar patterns as your sessions demand. The package ships with the figure-8 capsule, which excels when you need to capture two sound sources that face opposite sides of the microphone or when you want to create elegant stereo techniques such as Blumlein.

In daily studio work, the microphone slips easily into tight spaces around drum kits, guitar cabinets, and horn sections, yet it stands up to sound pressure levels as high as 156 dB without flinching. That capability makes it a confident choice for loud snare hits, close-mic’ed brass, and full drum overheads. During live shows, engineers appreciate the figure-8 pattern because it rejects sound from the sides, helping to control bleed on crowded stages.

The capsule locks to the preamp body with a precision-machined mechanism that keeps the connection secure, even when the microphone is adjusted repeatedly on a stand. An all-metal housing protects the internal electronics, while the balanced XLR output integrates with any professional audio interface, console, or stage box. Shure includes a stand adapter, a windscreen, and a zippered case so you can travel to sessions or gigs with everything organized and protected.

Whether you are pairing two units for immersive Blumlein room captures, placing one between two backing vocalists, or tucking it under a cymbal for a focused overhead, the BETA 181/BI delivers detailed, natural sound with minimal setup fuss. It is a reliable tool for engineers who need flexibility without sacrificing durability.
