A231
LARGE DIAPHRAGM CONDENSER
VOCAL MICROPHONE
OVERVIEW
The A231 is a large diaphragm condenser microphone built for the most discerning
studio user. With its externally-biased “true condenser” capsule and low-noise
circuitry, the A231 is able to capture the nuances of the human voice as well as the
rich overtones of acoustic instruments with natural warmth and in stunning detail.
An exceptionally consistent cardioid polar pattern focuses on the performance
while oering smooth o-axis rejection.
The 33 mm condenser capsule of the A231 features a precision-tensioned
diaphragm made from a specially formulated, heat-treated film with gold
deposition distributed evenly to the far edges of the diaphragm. The result is a
25% greater eective diaphragm area when compared to the capsule of a typical
large diaphragm microphone.
Behind the double-woven steel mesh grille of the A231, acoustic reflections and
diractions are minimized for transparent sound capture. The internal shock
mount isolates the capsule from mechanical vibrations, eliminating the need for a
bulky external shock mount. Proprietary impedance control between the capsule
and circuitry ensures consistent and reliable performance across a wide range of
environments.
Designed, machined, assembled, and tested by Audix in Wilsonville, Oregon.
