The 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 33 mm fixed-charge capsule features a 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 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.Main Features:Large 33 mm condenser capsuleCardioid Polar PatternProprietary internal shock mountLow noise preamp circuitryDesigned, machined & tested in the USASpecifications:Transducer / Capsule Technology: 33 mm fixed-charge condenser / 29 mm 3.4 micron gold-sputtered diaphragmFrequency Response: 40 Hz – 20 kHzPolar Pattern: CardioidOutput Impedance: 150 ohmsSensitivity: 23 mV / Pa @ 1 kHzSignal to Noise Ratio: 84 dBMaximum SPL: 140 dBDynamic Range: 130 dBEquivalent Noise Level: 10 dBAOperating Voltage: 48 V ( 4 V) PhantomConnector: 3-pin XLR mMaterials / Finish:Body: Machined aluminumGrille: Steel alloyWeight: 280 g / 10 oz
