BETA 87A

SUPERCARDIOID CONDENSER MICROPHONE

OVERVIEW

The Shure Model BETA 87A is a premium quality supercar- dioid hand-held electret condenser vocal microphone with ex- ceptionally smooth frequency response and high sound pres- sure level (SPL) capability. Used for professional sound rein- forcement, 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 su- percardioid pattern, with null points at approximately 125°, pro- vides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The BETA 87A oper- ates on phantom power.

FEATURES

SSmooth frequency response with gradual presence rise
