Shure Beta 87A Super Cardioid Condenser Vocal Microphone

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. 

A controlled low-frequency roll-off compensates for proximity effect and prevents the “boomy” sound often associated with close pick-up. 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.

Features :

• Smooth frequency response with gradual presence rise
