 Features and specs:

  • 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.)
  • 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.
