- BETA 87A Vocal Microphone -
The Shure BETA87A 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.
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.
How It Works
One of the world's best-selling, single-element, condenser mic, the BETA 87A puts singers on a pedestal. Tailored frequency response concentrates on the upper midrange to raise vocal presence in the mix. So voices cut through clearly and resonate deeply with your audience.
Why It's Better
Set your singing apart
The supercardioid pattern provides maximum isolation of your voice, giving you the chance to shine.
Never overpowered
Get right up on the mic without overwhelming the sound. Electronically controlled low-end roll-off keeps your bass from blasting over the mix.
Resists rattle
The advanced cartridge shock-mount system lets you handle the mic a little harder while absorbing any mechanical noise.
