Shure Beta 87A Handheld Condenser Microphone
Vocal microphone provides warm, accurate sound due to its supercardioid polar pattern.
Overview
The Shure Beta 87A is a precision-engineered supercardioid condenser vocal microphone with an exceptionally smooth frequency response. Built
to withstand extreme sound pressure levels, the Beta 87A is ideal for professional sound reinforcement and studio recording applications - and
constructed to withstand the rigors of touring.
Features
• Premier live performance microphone with Shure quality, ruggedness, and reliability
• Uniform supercardioid pick-up pattern for maximum gain before feedback and superior rejection of o -axis sound
• Smooth, wide frequency response with gradual presence rise and controlled proximity e ect tailored for vocals
• Advanced cartridge shock mount system absorbs mechanical shock and minimizes handling noise
• Dent-resistant steel mesh grille and enamel coated metal alloy construction resist wear and abuse
• E ective built-in pop lter reduces undesirable wind and breath noise
• Very low susceptibility to RF and electromagnetic hum
