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.
