Shure BETA 181/KIT – Side-Address Microphone, Four Capsules

Product Overview

The Shure BETA 181/KIT is a complete ultra-compact side-address condenser microphone system that ships with all four interchangeable capsules: cardioid, supercardioid, omnidirectional, and bidirectional. This single small-diaphragm condenser microphone covers drum overheads, piano, acoustic instruments, room ambience, and stereo techniques from one preamp. As part of the BETA 181 system, each capsule delivers a consistent, textbook polar response. For AV system designers specifying a versatile studio recording condenser microphone, the BETA 181/KIT combines high-SPL handling with a low-profile footprint and full pattern flexibility.

Product Description

The BETA 181/KIT pairs a compact preamplifier with four condenser capsules, each attaching by way of an innovative locking ring for a secure, repeatable connection. The side-address design, under 12 cm in length, supports discreet positioning and reduces stage clutter. As a high-SPL condenser microphone, it offers a wide dynamic range and exceptional low-frequency reproduction with no crossover distortion. The cardioid capsule suits drum overheads and piano, the supercardioid adds isolation for snare and close-miking, the omnidirectional captures natural room and ensemble ambience, and the bidirectional supports mid-side and Blumlein stereo. The included carrying case securely protects up to four capsules, and the transformer output with integrated XLR connection simplifies integration with any phantom-powered console. Comparable Shure options on our catalog include the single-capsule BETA 181/C and the BETA 181/BI bidirectional model.
