The Audix A231 captures vocals and your instruments with a rich, spacious, and warm tonality that cant be beat. 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. The design is also unique in that it is more compact than most large diaphragm studio microphones.
