SHURE BETA 87A HAND HELD VOCAL CONDENSER MICROPHONE
The Shure Beta 87A is a premium quality supercardioid hand-held electret
condenser vocal microphone with exceptionally smooth frequency response and high
sound pressure level capability. Used for professional sound reinforcement,
broadcasting, and studio recording applications, the Beta 87A combines superb
performance with the ruggedness needed for touring and field
production.
FEATURES:
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
The Beta 87A features a controlled low-frequency roll-off that compensates
for proximity effect and prevents the “boomy” sound often associated with close
pick-up. The characteristic Shure presence rise brightens the upper midrange.
The tight supercardioid pattern, with null points at approximately 125 degrees,
provides maximum isolation from other vocalists or instruments while offering
minimal off-axis coloration. The Beta 87A operates on phantom power.
