Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.\u003cbr\u003e\u003cbr\u003eThe Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the �boomy� sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.\u003cbr\u003e\u003cbr\u003eCartridge Type\u003cbr\u003eCondenser (electret bias)\u003cbr\u003e\u003cbr\u003eFrequency Response\u003cbr\u003e50 to 20,000 Hz\u003cbr\u003e\u003cbr\u003ePolar Pattern\u003cbr\u003eSupercardioid\u003cbr\u003e\u003cbr\u003eOutput Impedance\u003cbr\u003eRated at 150 ohms (100 ohms actual +\/- 20%)\u003cbr\u003eRecommended minimum load impedance: 800 ohms\u003cbr\u003e\u003cbr\u003eSensitivity (at 1,000 Hz)\u003cbr\u003eOpen Circuit Voltage -52.5 dBV\/Pa (2 mV)\u003cbr\u003e(1 Pa = 94 dB SPL)\u003cbr\u003e\u003cbr\u003eClipping Level (at 1,000 Hz)\u003cbr\u003e1000 ohm Load: -6 dBV (0.5 V)\u003cbr\u003e\u003cbr\u003eMaximum SPL (at 1,000 Hz)\u003cbr\u003e140.5 dB (0.25% THD, 1000 ohm load)\u003cbr\u003e\u003cbr\u003eSelf-Noise\u003cbr\u003e(equivalent sound pressure level; measured with true rms voltmeter)\u003cbr\u003e23.5 dB typical, A-weighted\u003cbr\u003e25.5 dB typical, weighted per DIN 45 405 Dynamic Range\u003cbr\u003e117 dB (maximum SPL to A-weighted noise level)\u003cbr\u003e\u003cbr\u003eSignal-to-Noise Ratio\u003cbr\u003e70.5 dB at 94 dB SPL (IEC 651)\u003cbr\u003e(S\/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.)\u003cbr\u003e\u003cbr\u003ePolarity\u003cbr\u003ePositive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3\u003cbr\u003e\u003cbr\u003ePower\u003cbr\u003ePhantom Supply Requirement: 11 to 52 Vdc, positive at both pins 2 and 3\u003cbr\u003e\u003cbr\u003eCurrent Drain: 1.0 to 1.2 mA\u003cbr\u003e\u003cbr\u003eConnector\u003cbr\u003eThree-pin (XLR) professional audio\u003cbr\u003e\u003cbr\u003eCase\u003cbr\u003eAluminum construction with blue metallic finish, and hardened steel grille with nickel satin chrome plating\u003cbr\u003e\u003cbr\u003eNet Weight\u003cbr\u003e207 grams (7.6 oz)\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConsistent supercardioid polar pattern for high gain-before-feedback\u003c\/li\u003e\n\u003cli\u003eSmooth response with gradual presence rise\u003c\/li\u003e\n\u003cli\u003eElectronic LF roll-off compensates for proximity effect\u003c\/li\u003e\n\u003cli\u003e117 dB dynamic range\u003c\/li\u003e\n\u003cli\u003eLow susceptibility to RFI andEM hum\u003c\/li\u003e\n\u003cli\u003eAdvanced shock-mounted cartridge system\u003c\/li\u003e\n\u003cli\u003eBuilt-in pop filter\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shure","offers":[{"title":"Default Title","offer_id":51790365720872,"sku":"NGTMP-BETA87A","price":260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/0406\/3016\/files\/BETA87A.jpg?v=1777931400","url":"https:\/\/churchgear.com\/products\/beta-series-supercardioid-handheld-condenser-microphone","provider":"ChurchGear","version":"1.0","type":"link"}
