Large-diaphragm condenser mic for clear, accurate audio.

The Audix A131 is a large diaphragm condenser microphone ideal for vocals, choir, piano, acoustic instruments and overheads. Featuring a contemporary, compact design, the A131 is the perfect choice for podcasting, professional audio production, studios and live stage performances. Housed in a precision-machined aluminum body, the fixed-charge capsule features a 30mm gold-sputtered diaphragm for wide, natural frequency response. With its well-behaved cardioid polar pattern, the A131 faithfully captures the detail of the performance while rejecting room noises and other unwanted, off-axis sounds. A double woven steel mesh grille and ultra-thin acoustic foam offers exceptional pop resistance for podcasting and vocals. Behind the grille, the open-air design of the capsule mounting system allows the A131 microphone to deliver transparent, uncolored sound. Proprietary impedance control between the capsule and circuitry ensures consistent and reliable performance across a wide range of environments. A unique and highly effective internal shock mount isolates the capsule from mechanical vibrations and touch noise, eliminating the need for a bulky external shock mount. Offering studio performance in a road-worthy package, the A131 also comes with a protective zippered carrying case and requires 48-52 V phantom power. For best results, the A131 should be used with a high-quality mic preamplifier and microphone cable.
