About this listing
The Audix A231 Microphone is their flagship large diaphragm condenser microphone, designed for studio and vocal/voice recording. The A231 provides detail and richness, ensuring a full and musical representation of the human voice, with virtually no noise or distortion.
The Audix A231 Microphone 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 offering smooth off-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 effective 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 diffractions 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.
