Electret element is mounted in a special housing which is out of reach to objects inserted into the sound holes. Built in limiter circuit automatically lowers the output level during loud sound intervals.Selectable lo-cut and hi-cut filters significantly reduce background noise. Stainless steel plate mounts flush or on a single gang electrical box.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOmni-directional 25’ pickup pattern.\u003c\/li\u003e\n\u003cli\u003eLow noise MOSFET pre-amplifier.\u003c\/li\u003e\n\u003cli\u003e500Hz-16Khz Frequency response.\u003c\/li\u003e\n\u003cli\u003eSwitch selectable hi-cut\/low-cut filters limit frequency response to 900-6khz significantly reducing background noise.\u003c\/li\u003e\n\u003cli\u003eSwitch selectable volume range: \"Line level\" (0db) or \"Microphone level\" (-30db)\u003c\/li\u003e\n\u003cli\u003eAdjustable gain in both volume ranges.\u003c\/li\u003e\n\u003cli\u003e100 Ohm unbalanced output.\u003c\/li\u003e\n\u003cli\u003eInternal peak limiter circuit (.5 sec response)\u003c\/li\u003e\n\u003cli\u003e3 position terminal block.\u003c\/li\u003e\n\u003cli\u003ePTTC fused and reverse polarity protected\u003c\/li\u003e\n\u003cli\u003ePower: 12 to 24VDC @ 10mA.\u003c\/li\u003e\n\u003cli\u003eOn-board voltage regulator and RFI filtering.\u003c\/li\u003e\n\u003cli\u003eS\/N ratio: more than 60DB\u003c\/li\u003e\n\u003cli\u003eSensitivity –45DB\u003c\/li\u003e\n\u003cli\u003eIndustrial temperature range –40 to 85C\u003c\/li\u003e\n\u003cli\u003eStainless steel plate mounts flush or on a single gang electrical box.\u003c\/li\u003e\n\u003cli\u003eDimensions: L 4.5” W 2.7” H 1.1”\u003c\/li\u003e\n\u003cli\u003eWeight .07lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSM1-TR flush mount microphone.\u003c\/li\u003e\n\u003cli\u003eMounting screws.\u003c\/li\u003e\n\u003cli\u003eWarning label.\u003c\/li\u003e\n\u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOptions:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSee Pre-amplifier board selection guide for alternate pre-amplifier form factors.\u003c\/li\u003e\n\u003cli\u003eAdd –LN to P\/N for ultra low noise (80db) and high sensitivity (–28db) microphone capsule\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ETS","offers":[{"title":"Default Title","offer_id":47903990448379,"sku":"SM1-TR","price":85.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/5032\/0891\/files\/SM1-TR_0.jpg?v=1769654298","url":"https:\/\/cctvbestbuys.com\/products\/ets-sm1-tr-ets-sm1-tr-flush-mount-tamper-resistant-omni-directional-microphone","provider":"CCTVBestBuys","version":"1.0","type":"link"}
