buy the board presented three potentiometer plastic cap, the quality is very good, the color random hair, if you do not like plastic, we have aluminum cap, buy please click hereThe power supply can choose our double 12V30W AC adapter, please buy click hereThe double-headed 3.5 audio cable, purchase please click hereThe 12V lossless WAV / MP3 audio decoder board, buy please click hereTheThe following is the wiring diagram of the board, please strictly according to map wiring, especially the power part of the wrong, to avoid failure.Overview of the boardThe bass is strong and the treble is crisp. Using the chip as the original: the default woofer for a TDA2050 - the output peak of 32W, two-channel unit for the two TDA2030 - the output peak of 18W +18 W. TDA2030, TDA2050, LM1875 can be completely interchangeable, if all replaced by TDA2050 or LM1875, please change the larger radiator. The amplifier chip has five pins: positive supply, negative supply, positive input, reverse input and output. Chip heat sink is connected with the negative, power work when the chip heat sink and do not short circuit, or immediately burned. The above diagram is the board wiring diagram, please carefully control wiring.The main par
