The wrong way is to connect the mains interface of the external power supply first, and then input the output interface of the external power supply to the digital power amplifier, because the digital power amplifier has a filter capacitor, so that the capacitor is charged and discharged, and a low-voltage small spark is generated within 0.1 seconds of contact. Although the low voltage has no effect, it is also a bad habit.\u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv style=\"margin: 0.0px;padding: 0.0px;\"\u003e\n\u003cdiv\u003e\u003cimg align=\"absmiddle\" referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i1\/88221699\/O1CN01mT2RQ21OQBeVkmymi_!!88221699.jpg\" style=\"max-width: 750.0px;\"\u003e\u003c\/div\u003e  \u003cdiv\u003e\u003cimg align=\"absmiddle\" referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i4\/88221699\/O1CN01Ox3MJ51OQBgJjct4R_!!88221699.png\" style=\"max-width: 750.0px;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n","brand":"GoMakerHive: Ignite Your Spark into a Blaze.","offers":[{"title":"Bass version","offer_id":66601604612400,"sku":"4656735507897","price":19.13,"currency_code":"USD","in_stock":true},{"title":"Full range version","offer_id":66601604645168,"sku":"4656735507896","price":19.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/2367\/2112\/files\/O1CN01pJrXhD1OQBeMIpyrz__88221699.webp?v=1777041983","url":"https:\/\/gomakerhive.com\/products\/tpa3116d2-100w-mono-subwoofer-power-amplifier-board-fever-finished-board","provider":"GoMakerHive: Ignite Your Spark into a Blaze.","version":"1.0","type":"link"}
