Please purchase two pieces for the two channels. The whole machine is reflow soldered with a beautiful layout. All the materials are full and the sound quality is super good!\u003cbr\u003e\u003cbr\u003e    Tips: The default power supply voltage of this power amplifier board is ±60---±85V for dual DC power supply. The lower the voltage, the smaller the output power.\u003cbr\u003e     \u003cbr\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e    1.

Over-temperature protection: Yes, the temperature of the radiator FET is higher than 100 °C, and the output is turned off!\u003cbr\u003e    13. Power amplifier board size: length x width x height = 116x50x85mm\u003cbr\u003e    14. Weight: 350 grams\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe use of precautions:\u003c\/b\u003e\u003cbr\u003e    1. The rated power supply voltage is ±80V for dual power supply, and the voltage can work normally at ±60---±85V. (If it is a power frequency transformer, please leave a margin when the voltage fluctuates. The power supply is 3 power supply lines, positive and negative power supply. Do not pick up the wrong to avoid burning the board\u003cbr\u003e    2. Power supply is recommended for DC dual power supply ±80V filter better power supply\u003cbr\u003e    3. Speaker recommended 10-25 inch 2 ohm-4 ohm speaker\u003cbr\u003e    4. Although the audio output has short circuit protection, try not to short circuit.\u003cbr\u003e    5. Please check carefully before powering on, to ensure that the wiring is correct before power can be applied.\u003cbr\u003e    7. The voltage amplification factor of this board is fixed at 50 times. If the output power is not enough, add the preamplifier according to the specific situation.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included: \u003c\/b\u003e\u003cbr\u003e- 1700W HIFI High Power IRS2092 Class D Mono Digital power amplifier board  1PCS\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":41019806646321,"sku":"61707","price":42.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1571640419-1.jpg?v=1780027495","url":"https:\/\/www.thanksbuyer.com\/fr\/products\/1700w-hifi-high-power-amplifier-irs2092-class-d-mono-digital-power-amplifier-board","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
