This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.\u003c\/p\u003e\r\n\r\n\u003cp\u003eSpecifications\u0026nbsp;\u003c\/p\u003e\r\n\r\n\u003cp\u003eType -\u0026nbsp;Electret Condenser\u003c\/p\u003e\r\n\r\n\u003cp\u003eFrequency Response -\u0026nbsp;20 to 20,000\u0026nbsp;Hz\u003c\/p\u003e\r\n\r\n\u003cp\u003ePolar Pattern -\u0026nbsp;Cardioid\u003c\/p\u003e\r\n\r\n\u003cp\u003eOutput Impedance -\u0026nbsp;EIA rated at 150 \u0026nbsp;\u0026Omega; (85 \u0026nbsp;\u0026Omega; actual)\u003c\/p\u003e\r\n\r\n\u003cp\u003eSensitivity -\u0026nbsp;at 1 kHz, open circuit voltage\u0026nbsp;-45\u0026nbsp;dBV\/Pa[1] (5.6\u0026nbsp;mV)\u003c\/p\u003e\r\n\r\n\u003cp\u003eMaximum SPL -\u0026nbsp;1 kHz at 1% THD, 1 k\u0026Omega; load\u0026nbsp;136\u0026nbsp;dB SPL\u003c\/p\u003e\r\n\r\n\u003cp\u003eSignal-To-Noise Ratio -\u0026nbsp;Ref. 94 dB SPL at 1 kHz\u0026nbsp;78\u0026nbsp;dB[2]\u003c\/p\u003e\r\n\r\n\u003cp\u003eClipping Level -\u0026nbsp;1 kHz at 0.25% THD, 1 k\u0026Omega; load\u0026nbsp;-4\u0026nbsp;dBV (0.63\u0026nbsp;V)\u003c\/p\u003e\r\n\r\n\u003cp\u003eHum Pickup -\u0026nbsp;typical, at 60 Hz, equivalent SPL\/mOe\u0026nbsp;-3\u0026nbsp;dB\u003c\/p\u003e\r\n\r\n\u003cp\u003ePolarity -\u0026nbsp;Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3\u003c\/p\u003e\r\n\r\n\u003cp\u003eWeight\u003c\/p\u003e\r\n\r\n\u003ctable\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd rowspan=\"1\"\u003eNet\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e0.230\u0026nbsp;kg (0.5\u0026nbsp;lbs)\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd rowspan=\"1\"\u003ePackaged\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e0.740\u0026nbsp;kg (1.625\u0026nbsp;lbs)\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\r\n\u003cp\u003eAttenuator Switch -\u0026nbsp;0 or \u0026minus;10 dB, lockable\u003c\/p\u003e\r\n\r\n\u003cp\u003eConnector -\u0026nbsp;Three-pin professional audio (XLR), male\u003c\/p\u003e\r\n\r\n\u003cp\u003eHousing -\u0026nbsp;Steel construction with vinyl metallic paint finish and stainless steel screens\u003c\/p\u003e\r\n\r\n\u003cp\u003eEnvironmental Conditions\u003c\/p\u003e\r\n\r\n\u003ctable\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd rowspan=\"1\"\u003eOperating Temperature\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e-6.7\u0026deg; to 49\u0026deg; C (20\u0026deg; to 120\u0026deg; F)\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd rowspan=\"1\"\u003eStorage Temperature\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e-29\u0026deg; to 74\u0026deg; C (-20\u0026deg; to 165\u0026deg; F)\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd rowspan=\"1\"\u003eRelative Humidity\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e0 to 95%\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\r\n\u003cp\u003ePower Requirements\u003c\/p\u003e\r\n\r\n\u003cp\u003e11 to 52\u0026nbsp;V\u0026nbsp;DC phantom power (1.2 \u0026nbsp;mA)\u003c\/p\u003e\r\n\r\n\u003cp\u003e[1] 1 Pa=94 dB SPL\u003c\/p\u003e\r\n\r\n\u003cp\u003e[2] S\/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cimg src=\"https:\/\/s3.us-east-2.amazonaws.com\/shure-pubs-staging\/graphics\/f_c725dfdf-a701-4c2d-83bf-f7f821a54c91-ENG.png\" style=\"height:260px; width:800px\" \/\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003eBlock Diagram\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cimg src=\"https:\/\/s3.us-east-2.amazonaws.com\/shure-pubs-staging\/graphics\/f_527bc994-eba7-490b-985c-722c46ef8bac-ENG.png\" style=\"width:585.2112px\" \/\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003eTypical Frequency Response\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cimg src=\"https:\/\/s3.us-east-2.amazonaws.com\/shure-pubs-staging\/graphics\/f_118ac748-70c0-41a1-b888-e4b89a894e6b-ENG.png\" style=\"width:740.9332px\" \/\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003eTypical Polar Patterns\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cimg src=\"https:\/\/s3.us-east-2.amazonaws.com\/shure-pubs-staging\/graphics\/f_735dc65b-8bba-4e2a-9677-5aa80c6bf160-ENG.png\" style=\"width:642.4431999999999px\" \/\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003eOverall Dimensions\u003c\/p\u003e","brand":"Shure","offers":[{"title":"Default Title","offer_id":53585153065297,"sku":"SM81LC","price":498.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/9686\/2033\/files\/9vvG71wxEwRsjxpLDGd1wZP3FV1KeseO.jpg?v=1776794183","url":"https:\/\/dynaphos.com\/en\/products\/kondienzatorien-instrumientalien-mikrofon-shure-sm81-lc-cardioid","provider":"Dynaphos","version":"1.0","type":"link"}
