{"product_id":"beta-series-half-cardioid-condenser-microphone","title":"BETA Series Half-Cardioid Condenser Microphone","description":"\u003cp\u003eThe Shure Beta 91A is designed for use with kick drums, as well as other traditional low-frequency applications including piano. Featuring an updated microphone capsule, integrated preamplifier, and XLR connection, Beta 91A offers a strong low-frequency response and is specifically tailored for bass frequency applications. The Beta 91A combines superior attack and punch for studio-quality sound, even at extremely high sound pressure levels (SPL).\u003cbr\u003e\u003cbr\u003eType\u003cbr\u003eElectret Condenser\u003cbr\u003e\u003cbr\u003eFrequency Response\u003cbr\u003e20 to 20,000 Hz\u003cbr\u003e\u003cbr\u003ePolar Pattern\u003cbr\u003eHalf-cardioid (cardioid in hemisphere above mounting surface)\u003cbr\u003e\u003cbr\u003eImpedance\u003cbr\u003e146 Ohms\u003cbr\u003e\u003cbr\u003eSensitivity (at 1 kHz, open circuit voltage)\u003cbr\u003e-48.5 dBV\/Pa (3.8mV)\u003cbr\u003e1 Pascal=94 dB SPL\u003cbr\u003e\u003cbr\u003eMaximum SPL (1 kHz at 1% THD)\u003cbr\u003e1000 Ohm load: 151 dB, 2500 Ohm load: 155 dB\u003cbr\u003e\u003cbr\u003eSignal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz)\u003cbr\u003e64 dB\u003cbr\u003eS\/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted\u003cbr\u003e\u003cbr\u003eDynamic Range (at 1 kHz)\u003cbr\u003e1000 Ohm load: 121.5 dB\u003cbr\u003e2500 Ohm load: 125.5 dB\u003cbr\u003e\u003cbr\u003eCommon Mode Rejection (20 Hz to 20 kHz)\u003cbr\u003e\u0026gt; 55 dB\u003cbr\u003e\u003cbr\u003eClipping Level (20Hz-20 kHz at 1% THD)\u003cbr\u003e1000 Ohm load: 7.50 dBV, 2500 Ohm load: 12.5 dBV\u003cbr\u003eTHD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL\u003cbr\u003e\u003cbr\u003eSelf Noise (typical, equivalent SPL, A-weighted)\u003cbr\u003e29.5 dB SPL-A\u003cbr\u003e\u003cbr\u003ePolarity\u003cbr\u003ePositive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3\u003cbr\u003e\u003cbr\u003eWeight\u003cbr\u003eNet: 470 g (16.6 oz.)\u003cbr\u003e\u003cbr\u003eFrequency Contour Switch\u003cbr\u003e7 dB of attenuation centered at 400 kHz\u003cbr\u003e\u003cbr\u003eConnector\u003cbr\u003eThree-pin professional audio (XLR), male, balanced\u003cbr\u003e\u003cbr\u003ePower Requirements\u003cbr\u003e11-52 Vdc phantom power, 5.6 mA\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound\u003c\/li\u003e\n\u003cli\u003ePrecision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter\u003c\/li\u003e\n\u003cli\u003eFrequency response tailored for kick drum\/low frequency applications with a wide dynamic range for use in high SPL environments\u003c\/li\u003e\n\u003cli\u003eTwo-position contour switch to maximize attack and clarity depending on application: select the flat response setting for natural sound in most applications or the “low-mid scoop” setting for a strong low frequency “punch” with plenty of higher frequency attack\u003c\/li\u003e\n\u003cli\u003eRequires no external mounting or accessories for ease of use and storage\u003c\/li\u003e\n\u003cli\u003eFurnished with zipper pouch\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shure","offers":[{"title":"Default Title","offer_id":51790322139432,"sku":"NGTMP-BETA-91A","price":242.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/0406\/3016\/files\/BETA_2091A.jpg?v=1777931039","url":"https:\/\/churchgear.com\/products\/beta-series-half-cardioid-condenser-microphone","provider":"ChurchGear","version":"1.0","type":"link"}
