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 oering 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 eective 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

diractions 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.
