The higher the voltage and the smaller the load, the greater the power. The voltage supply range of the board means that all voltage boards within this range can work normally. Not all voltage and load power are as big as the power output indicated. For example, 12V power supply for 4 ohm load, the maximum power is 15W, and the maximum power is 7.5W at 8 ohm; 24V power supply: 4 Ω, maximum power: 50W, maximum power: 25W at 8 Ω; At any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the loud volume band will not operate, the power will be reduced and cut off, and the corresponding power output cannot be reached.\u003cbr\u003e\u003cb\u003e\u003cbr\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Amplifier Board\u003cbr\u003e\u003cfont color=\"#FF0000\"\u003e\u003cb\u003e\u003cbr\u003eNote:\u003cbr\u003e- The board must be powered by Dual DC power supply.\u003c\/b\u003e\u003c\/font\u003e\u003cbr\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-1.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-3.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-4.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-5.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-6.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/79069\/79069-7.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders","offers":[{"title":"Default Title","offer_id":41028253548593,"sku":"79069","price":14.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1678842496-4.jpg?v=1780306134","url":"https:\/\/www.thanksbuyer.com\/ja\/products\/umsong-high-performance-500w-hifi-digital-amplifier-board-mono-super-lm3886-irs2092s","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
