Shure Beta 181 Side-Address Condenser Microphone w/ Interchangeable Capsules Kit

About: Shure Beta 181 Side-Address Condenser Microphone w/ Interchangeable Capsules Kit

The Shure BETA 181 is an ultra-compact, small-diaphragm side-address condenser microphone, designed for discreet 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 Ultra-Compact Side-Address Instrument Microphone Kit comes with one (1) each Cardioid, Supercardioid, Omnidirectional and Bidirectional Polar Pattern Capsules

Features

• Interchangeable polar pattern capsules attach to a compact preamplifier with integrated XLR connections for the ultimate in low-profile application 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 capsule.

Application recommendations:

• 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)
