The board is a single channel amplifier board, and for those who need dual channels, two amplifier boards are required. The circuit design uses A970\/C2240 high-voltage audio tube dual differential circuit and A1145\/C2705 for voltage amplification, promoting the use of medium power tube A1837\/C4793, and the output stage uses A1943\/C5200 high-power tube; The power supply range is wide, with a DC of ± 20V-90V. As long as sufficient power is supplied, it can easily achieve an output power of 300W. The driving force is extremely strong, and there is no pressure to drive a 15 inch horn.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color:rgb(255, 102, 0);font-size:22px\"\u003e\u003cstrong\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eParameter: \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:arial, helvetica, sans-serif\"\u003ePower supply voltage: DC ± 20-90V (recommended use: ± 20V-75V) Do not challenge the voltage limit, and switch mode power supply cannot be used for power supply. ） \u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:arial, helvetica, sans-serif\"\u003eOutput power: 300W (8 Ω box) \u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:arial, helvetica, sans-serif\"\u003ePCB board size: 150MM * 75MM\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color:rgb(255, 102, 0);font-size:22px\"\u003e\u003cstrong\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003ePackage Include: \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:arial, helvetica, sans-serif\"\u003e1X power amplifier board\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S8cc7933604774d9da2c20bf7d92bd09eA.jpg\" slate-data-type=\"image\"\u003e\u003cbr\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S1ec634dc662e45178312ab298a07677a4.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S14abb716fc13444e83951f0590b375a5P.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S8e9e70e1f01a46f29139b03d4eba908e9.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S507b4f96ca2b4b948b6ed0ec1b4b32e8Z.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S7f039f44b16446f6a62161ec8866afa94.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S09bf5f6707b14cba837a89f9d3b0dfbfY.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S792b80896b604ed9945e5f07f12f02e4d.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S7f8e462b5b7743cabb1717abbc50b94c6.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S4c071384000e4147b76709e3540fffd9I.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S8408b7386fe64dccb71abf59d83bbb9b1.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S14aa50c4ee534f1e96973902e35591e7g.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sbc664546476d4d7fad9abdda3c2b55bdx.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S7408d5ac8322477594b2ce8056304f70n.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sa35b33b8259040d7b4cb8dce56db2398d.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Saff110ccceef460ab2454c722320b24ev.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S978a027ab722498bb27ea54414a7c1c0C.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S8227f7b8ce0a4cc09612170c9c19000am.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S9a49728de3e7459786862d8c469d5281h.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"300W","offer_id":55276373344555,"sku":"14:618#300W","price":68.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/S4614aa7b843f4bbea6e9b8d882631916K.webp?v=1788245014","url":"https:\/\/yoeruyo.com\/products\/300w-mono-power-amplifier-board-1943-5200-hifi-high-power-audio-amplifier-board-with-speaker-protection","provider":"Yoeruyo","version":"1.0","type":"link"}
