The Audix 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 offering smooth off-axis rejection.
