 Subwoofer amplifier board finished board, the output power: left and right channel 18W +18 W, subwoofer 32W, fully compatible with LM1875. The latest version of TDA2050A (ئ۲٫۱ )+

TDA2030A + NE5532 three-channel (2.1) subwoofer amplifier board finished board, output power:Equipped with 12V decoder board power supply output and decoder board audio input (the actual wiring decode board audio input to the ground GND do not be connected to reduce interference).

Overview of the board

The bass is strong and the treble is crisp. Using the chip as a new 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.
