Feature: ?? 1. TPA3118 high-power amplifier board 2 * 30w 8 ohm + 60w 4 ohm output, this board uses the official standard circuit to turn on sufficient power and low heat, 32db gain test. 2. When the volume is not turned on, the volume is turned on at the maximum and no low noise can be heard. The test power supply is 3c and ul certified power supply. As long as the power supply does not interfere with the power amplifier board itself, as long as the audio cable is connected, there will be no interference. If there is no interference, it is perfect. 3. This circuit design uses the tpa3118 chip test application circuit instead of the official standard circuit, so please do not make any changes to the composition circuit on the power amplifier board to avoid unnecessary losses due to overheating! ? Specifications: ? Power supply: DC15-25V Current: a???4A Output power: 30 watts + 30 watts + 60 watts Output channel: 2.1 three channels Frequency response range: 20-18.5 kHz Harmonic distortion: THD-1% The power requirement is 15-25V 4A or higher, 2 * 30W 8 ohm + 60W 4 ohm can work normally. If you only use a power supply lower than 3A, it is ideally 2 * 25W 8 ohm + 50W 8 ohm.
