Automatically stop the output.The boot delay is 5 seconds to output music, and the non-impact sound experience is better. There are 2 op amps and 3 op amps versions and Bluetooth versions, which can be flexibly matched.\u003cbr\u003e\n\u003cbr\u003e\nThe Bluetooth version also supports AUX wired input, and the audio source is automatically switched. The external input is automatically disconnected when the Bluetooth is connected to the mobile phone, and the external wired input is automatically cut back when the mobile phone disconnects the Bluetooth. The switching process will not produce any noise, which is very easy to use.\u003cbr\u003e\n\u003cbr\u003e\nPower supply: The DC voltage is 19V to 50V, and it can be used with a switching power supply or a linear DC power supply. The motherboard is composed of 6 audio power supply dedicated fever capacitors in parallel. The ultra-low internal resistance filter line-up provides clean, stable and powerful electrical energy to the chip.\u003cbr\u003e\n\u003cbr\u003e\nBoard size: length 135mm, width 75mm, height 29mm.\u003cbr\u003e\n\u003cbr\u003e\nPacking:\u003cbr\u003e\n\u003cbr\u003e\n1Pcs TPA3255 Power Amplifier\u003c\/span\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cimg cke-id=\"img38\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sfb1b7276252e44db85cf126d9dbd54a7g.jpg?width=800\u0026amp;height=61\u0026amp;hash=861\"\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cimg cke-id=\"img42\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sadf2068655f0493eacd56c60247f1042t.jpg?width=800\u0026amp;height=1000\u0026amp;hash=1800\"\u003e\u003cbr\u003e\n\u003c\/p\u003e\u003cdiv\u003e\u003cimg cke-id=\"img56\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sd621adff1e2d417fa165d7771ab72b49D.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg cke-id=\"img57\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S77ec35bcd67543f9b3a4ead9083ca4f8E.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg cke-id=\"img58\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S2de05c8eb86a41d5bb078c1805e8c99bj.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg cke-id=\"img59\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sd8f17d4d27f142e09a7eef269694e45aC.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg cke-id=\"img60\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S50b6b0cb83cd441b89d9da5e6c5c797aT.jpg\"\u003e\u003c\/div\u003e\u003cimg cke-id=\"img61\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S524bda34c2ca48b199f1ac640693dac4Q.jpg\"\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\u003cimg cke-id=\"img-8-48\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S1d3e661983b146a6953fe6a471f58087m.jpg?width=1000\u0026amp;height=2373\u0026amp;hash=3373\"\u003e\u003c\/div\u003e\n","brand":"SOTAMIA Audio Factory Store","offers":[{"title":"Default Title","offer_id":49261432307963,"sku":"A1D01415","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/9662\/2843\/files\/S36fcaafd5d88468e933480e33aa35ceaT.webp?v=1788429543","url":"https:\/\/sotamia.com\/es\/products\/sotamia-tpa3255-bluetooth-power-amplifier-board-315w-315w-2-0-channel-aux-digital-audio-hifi-amplifier-temperature-control","provider":"SOTAMIA Audio Factory Store","version":"1.0","type":"link"}
