The Shure BETA 181/S is an ultra-compact side-address condenser with a supercardioid capsule, under 12cm long, built to tuck into drum kits and tight stage real estate where full-size condensers won’t fit, and the tighter pattern for maximum isolation on loud stages. The capsule unscrews from the shared preamp body, so one mic locker covers all four patterns with RPM181 capsules.
