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. <\/p>\n<p> 2. Common &#8220;high to low&#8221; 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. <\/p>\n<p> 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. <\/p>\n<div>\n<div>\n<ul>\n<li>\n<div>\n     <img decoding=\"async\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/60788793578788.jpg\">\n    <\/div>\n<\/li>\n<li>\n<div>\n     <img decoding=\"async\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/15773211366416.png\">\n    <\/div>\n<\/li>\n<li>\n<div>\n     <img decoding=\"async\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/2272987481776.jpg\">\n    <\/div>\n<\/li>\n<li>\n<div>\n     <img decoding=\"async\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1394826573999.jpg\">\n    <\/div>\n<\/li>\n<li>\n<div>\n     <img decoding=\"async\" alt=\"\" src=\"https:\/\/cf.cjdropshipping.com\/20200709\/1058052405947.jpg\">\n    <\/div>\n<\/li>\n<\/ul><\/div>\n<\/div>\n<p><strong> <img decoding=\"async\" alt=\"undefined\" src=\"https:\/\/cf.cjdropshipping.com\/16778016\/1631681801665777664.jpg\"> <\/strong> &nbsp;<br \/>\n<strong> <img decoding=\"async\" alt=\"undefined\" src=\"https:\/\/cf.cjdropshipping.com\/16778016\/1631681805889441792.jpg\"> <\/strong> &nbsp;&nbsp;&nbsp;<br \/><\/p>","protected":false},"excerpt":{"rendered":"<p>The role of car audio high to low 1.
