Pure analog input without Bluetooth interference, compatible with high-end DAC, suitable for desktop audio setup\u003cbr\u003e\u003cbr\u003eProduct Introduction\u003cbr\u003eThe chip model TPA3255 used in this model is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring true high-end sound quality to the circuit. This device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology enables devices to maintain ultra-low distortion throughout the entire audio frequency band while showcasing sound quality. This device operates in AD mode and can drive up to 2 315W\/4R loads and 2 150W (uncut power)\/8R loads at a THD of 1.5%. It also features a 2VRMS analog input interface that supports seamless connection with high-performance DACs such as TI's PCM5242. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power idle loss (less than 2.5W). This can be achieved through an 85mR MOSFET and an optimized gate driver scheme. This scheme can significantly reduce idle losses compared to traditional discrete implementation schemes.\u003cbr\u003e\u003cbr\u003eProduct Parameters:\u003cbr\u003eInput voltage: DC 18-55V (DC power supply input voltage must be above 18V for sound output); Current above 5A\u003cbr\u003eOutput power: 2 * 300W (up to 315W+315W)\u003cbr\u003eChip model: TPA3255\u003cbr\u003eFrequency response: 20Hz to 20KHz\u003cbr\u003eDynamic range:\u0026gt;100dB\u003cbr\u003eSNR ：\u0026gt;111dB\u003cbr\u003eWork efficiency:\u0026gt;90%\u003cbr\u003eProduct size: 122.5X73.5X24.0MM\u003cbr\u003eOutput power:\u003cbr\u003e315W\/4 Ω distortion 1.5%\u003cbr\u003e185W\/8 Ω distortion 1.5%\u003cbr\u003e260W\/4 Ω distortion 1%\u003cbr\u003e150W\/8 Ω distortion 1%\u003cbr\u003e\u003cbr\u003eNotes:\u003cbr\u003eDo not short circuit the audio cable; The power supply cannot be reversed; The maximum voltage shall not exceed 50V\u003cbr\u003eThe input voltage of the DC power supply must be above 18V for sound output, and the maximum should not exceed 52V.\u003cbr\u003e\u003cbr\u003eProduct List:\u003cbr\u003e1X power amplifier board\u003cbr\u003e1X accessory kit\u003cbr\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Se03bf2167c82460681608795bbbae42bK.png\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S4b785e7abf9e4e8bb94905a935da0995M.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Se5c285ee7d5b439f97da9f0a0c2e1a31P.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sb96e181ec59943d2bf44d61298c42124g.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S87aece32dcda4f8e95934745d2c766ecH.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Se8fcb25a522f48a094e4b369eb50887fo.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S3ee4ec97600e4be4ab23695738f8a5dfl.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sa55f707866ff48d1913117bfc33b1c20M.jpg\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf390071765b54d6bbe51dfbee269d181u.jpg\"\u003e\n\u003c\/div\u003e\u003c\/div\u003e\r\n","brand":"Yoeruyo","offers":[{"title":"300Wx2","offer_id":55374284554539,"sku":"14:1202#300Wx2","price":148.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/Se03bf2167c82460681608795bbbae42bK.webp?v=1788325273","url":"https:\/\/yoeruyo.com\/products\/dc18-55v-tpa3255-hifi-digital-amplifier-module-dual-channel-300w-2-stereo-audio-speaker-no-bluetooth-interfere-pure-sound","provider":"Yoeruyo","version":"1.0","type":"link"}
