High to low: Used to convert the high-level audio voltage output by the speaker into a low-level audio signal for input by other power amplifiers.\n \u003cbr\u003e\n \u003cbr\u003e\n 2. Common \"high to low\" converters are roughly divided into passive and active types. Passive high-to-low does not need to be connected to the battery. The high signal has recently gone out, and the middle is a few resistors. So to be precise, passive high to low should be called an attenuator. Active high-to-low requires battery power supply. The high signal is converted into a low signal through an amplifier circuit. It belongs to an audio amplifier that plays a role of reduction. Some active high-to-low with volume adjustment are actually the principle of the power amplifier.\n \u003cbr\u003e\n \u003cbr\u003e\n 3. It is not necessary to use high-to-low in the audio system. Only when the original car host does not have RCA output, you can consider installing a high-to-low to solve this problem, but the ordinary high-to-low will be Some audio signals are lost.\n\u003c\/p\u003e\n\u003cdiv\u003e\n \u003cdiv\u003e\n  \u003cul\u003e\n   \u003cli ng-drop=\"true\" ng-drop-success=\"dropComplete($index,$data)\" ng-repeat=\"item in picContainer track by $index\"\u003e\n    \u003cdiv ng-drag=\"true\" ng-drag-data=\"item\" draggable=\"false\"\u003e\n     \u003cimg ng-src=\"https:\/\/cf.cjdropshipping.com\/20200709\/60788793578788.jpg\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/60788793578788.jpg\"\u003e\n    \u003c\/div\u003e\n   \u003c\/li\u003e\n   \u003cli ng-drop=\"true\" ng-drop-success=\"dropComplete($index,$data)\" ng-repeat=\"item in picContainer track by $index\"\u003e\n    \u003cdiv ng-drag=\"true\" ng-drag-data=\"item\" draggable=\"false\"\u003e\n     \u003cimg ng-src=\"https:\/\/cf.cjdropshipping.com\/20200709\/15773211366416.png\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/15773211366416.png\"\u003e\n    \u003c\/div\u003e\n   \u003c\/li\u003e\n   \u003cli ng-drop=\"true\" ng-drop-success=\"dropComplete($index,$data)\" ng-repeat=\"item in picContainer track by $index\"\u003e\n    \u003cdiv ng-drag=\"true\" ng-drag-data=\"item\" draggable=\"false\"\u003e\n     \u003cimg ng-src=\"https:\/\/cf.cjdropshipping.com\/20200709\/2272987481776.jpg\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/2272987481776.jpg\"\u003e\n    \u003c\/div\u003e\n   \u003c\/li\u003e\n   \u003cli ng-drop=\"true\" ng-drop-success=\"dropComplete($index,$data)\" ng-repeat=\"item in picContainer track by $index\"\u003e\n    \u003cdiv ng-drag=\"true\" ng-drag-data=\"item\" draggable=\"false\"\u003e\n     \u003cimg ng-src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1394826573999.jpg\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1394826573999.jpg\"\u003e\n    \u003c\/div\u003e\n   \u003c\/li\u003e\n   \u003cli ng-drop=\"true\" ng-drop-success=\"dropComplete($index,$data)\" ng-repeat=\"item in picContainer track by $index\"\u003e\n    \u003cdiv ng-drag=\"true\" ng-drag-data=\"item\" draggable=\"false\"\u003e\n     \u003cimg ng-src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1058052405947.jpg\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1058052405947.jpg\"\u003e\n    \u003c\/div\u003e\n   \u003c\/li\u003e\n  \u003c\/ul\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\n\u003cstrong\u003e\n \u003cimg alt=\"undefined\" src=\"https:\/\/cf.cjdropshipping.com\/16778016\/1631681801665777664.jpg\" max-width=\"790\"\u003e\n\u003c\/strong\u003e\n \n\u003cstrong\u003e\n \u003cimg alt=\"undefined\" src=\"https:\/\/cf.cjdropshipping.com\/16778016\/1631681805889441792.jpg\" max-width=\"790\"\u003e\n\u003c\/strong\u003e\n   \n\u003cbr\u003e","brand":"M K M ONLINE STORE","offers":[{"title":"Ինչպես ցույց է տրված","offer_id":58492696330624,"sku":"CJQCMTQT00172-As shown","price":284.96,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0937\/6638\/6048\/files\/15773211366416.jpg?v=1784471294","url":"https:\/\/mkmonlinestore.com\/hy\/products\/car-audio-noise-reduction","provider":"M K M ONLINE STORE","version":"1.0","type":"link"}
