Shure BETA87A Handheld Condenser Microphone – Super-Cardioid

Features of the Shure BETA87A Handheld Condenser Microphone – Super-Cardioid:

• Smooth frequency response with gradual presence rise
• Highly consistent supercardioid polar pattern provides superior gain-before-feedback
• Electronic low-frequency roll-off compensates for proximity effect
• Wide dynamic range (117 dB) and low distortion characteristics
• Very low susceptibility to RFI and electromagnetic hum
• Advanced cartridge shock-mount system absorbs mechanical shocks and reduces handling noise
• Built-in pop filter reduces undesirable wind and breath sounds
• Legendary Shure quality and reliability
