Description

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.

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.)
  • Premier live performance microphone with Shure quality, ruggedness, and reliability
  • Compact preamp attaches to four interchangeable capsules
  • Wide Frequency response tailored for wide dynamic range applications for use in high SPL environments
  • Side-address form allows for discreet positioning in tight performance and recording settings
  • Innnovative locking ring provides a secure connection between capsule and preamp
  • Hardened steel mesh grille resists denting, wear, and abuse
  • Compact design, under 12 cm (5 in.), reduces stage clutter
  • Furnished with stand adapter and carrying case
