The circuit adopts direct coupling and has good low-frequency response; the input stage adopts differential amplification with low noise; the output stage adopts Darlington composite tube, which has high gain, high power and low distortion; This circuit is especially suitable for making home power amplifiers and power amplifier circuits for active speakers, and the effect is very good.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eThe OCL high-power amplifier kit is dual-channel, and the two-channel circuit principle is exactly the same. Take the right (R) channel as an example. In the circuit, Q1 and Q3 are the differential amplifier input stages, Q5 is the excitation stage, and Q7 and Q11, Q7 and Q11 constitutes a composite complementary output stage. The output signal is taken out from the Q11 emitter and Q13 collector. The output audio signal can directly drive the loudspeaker to emit a loud sound. This circuit also adds R25, R27, C11, C13 to reduce static noise.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eThe transformer in the store is a 12V 8W dual power transformer\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003ePower supply voltage: dual power supply AC12-18V\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eOutput power: Po=20W+20W (RL=8Ω), 30W+30W (RL=4Ω)\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eLoad impedance: 4-8 ohms (8 ohms\/30-60W is recommended for speakers)\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eOutput impedance: 4-8 Ω.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H1c69a805878f4001a3a3d3dbd70bbad2s.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H015797525bd84d24a62a68581ce50487x.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H99f240efa19341d29523c6575690d89ba.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hee8570be7c8f4371b53f895a6a2f3b12c.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H1216c709bc464b4dbd5b5532b9e20882A.png\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hf4c678255a434f9baabf73b0d584e8aaN.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hbe8976fa61dc486c90bdf0ca814b7f95T.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H2467f3d56f3b448896abe2a2ec2cc4e7E.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Headba9dce96d4a948487e9945eb91b9e4.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/HTB1ByqaaOzxK1Rjy1zkq6yHrVXa0.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Finesse Room","offers":[{"title":"Default Title","offer_id":56377351373135,"sku":"\u003cnone\u003e","price":9.96,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/0603\/1183\/files\/H0ba7e68842ef4058ab09de4492618b4fm.webp?v=1762781999","url":"https:\/\/www.mastegod.site\/products\/electronic-diy-kits-ocl-amplifier-board-suite-ac-12-18v-100w-dual-channel-stereo-eletronica-electric-experiment-diy-electronic","provider":"Mastegod ","version":"1.0","type":"link"}
