The Shure Beta 181 is an ultra-compact, small-diaphragm side-address condenser instrument microphone, designed for discrete placement and control in live and studio environments. Featuring interchangeable cardioid, supercardioid, omnidirectional and bidirectional capsule options for superior versatility, the small diaphragm design provides superior audio with consistent, textbook polar responses in a form factor small enough to get close to the source in the tightest conditions.
The Beta 181/BI comes with a bidirectional capsule. It is ideal for for mono drum overhead, dual instrument sound source applications, and Blumlein stereo technique (pair of Beta 181/BI). This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc.
• Ultra-Compact Side-Address Condenser Instrument Microphone with Bidirectional Polar Pattern Capsule
• 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; other capsules available separately)
• 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)
