TPA3118DD2 Subwoofer Amplifier Board 30Wx2+60W HiFi High

1. TPA3118D2 high power amplifier board 2*30W 8 ohm +60W 4 ohm output, this board uses official standard circuit to open enough power and low heat, 32dB gain test
2. When the volume is not plugged in, the volume is turned up to the maximum and the low noise is not heard.As long as the power supply does not interfere with the power amplifier board itself, there is no interference, as long as you connect the audio cable. If there is no interference, then it is perfect.
3. This circuit design uses the test application circuit of TPA311X chip instead of the official standard circuit, so please do not make any changes to the circuit of the component on the power amplifier board, so as to avoid unnecessary loss caused by overheating of the chip!
Maximum Power Per Channel: 60W
