Shure PGA81

Shure PGA81 Cardioid Condenser Instrument Microphone

Overview

The Shure PGA81 is a professional-quality, small-diaphragm condenser microphone specifically engineered for the precise, uncolored capture of acoustic instruments. Whether deployed in a demanding live sound reinforcement setup or a critical studio recording environment, the PGA81 delivers a highly detailed, flat frequency response that faithfully reproduces the delicate nuances of acoustic guitars, pianos, strings, and drum overheads. Featuring a sleek, unobtrusive black metallic finish, this microphone seamlessly blends into stage environments while its cardioid polar pattern ensures excellent rejection of off-axis noise and high gain-before-feedback. For audio engineers seeking reliable, high-fidelity acoustic pickup without breaking the bank, the PGA81 is an indispensable tool.
