Fuhjythy HIFI TPA3116 Bluetooth Amplifier Audio Board 100Wx2 Class D Digital Sound Amplifier 2.0 Stereo Amp Power Amplificador Easy Install

1) The size of the power supply is related to the power of the speaker used. For example, if an 8 ohm 100W speaker is used with a 24V power supply, the current is at least 6A or more, and the current is too small. Sound caton may occur. Reducing the volume and reducing the output power can solve this problem. 2) The power supply voltage cannot be higher than 26V, and if it is higher than 26V, the circuit board be burned. If the power is a speaker within 100W, appropriately reduce the power supply voltage (such as 12V power supply) or turn down the playback volume! The larger the power supply voltage of the speaker 100W, the better (within 26V).If there is a "" in the speaker playing music, the first consideration is that the power supply is insufficient and a larger power supply is used for power supply. Power supply selection:The power supply range of this product is DC12-24V, compatible with the standard 5.5 x 2.5MM.The power adapter plug is recommended to use a 12V/24V standard power adapter with a current output of more than 10A. 3) If the power amplifier board restarts after the volume is turned up during playback, the power supply is insufficient and the power supply with a larger output current can be replaced. Speaker selection: The power amplifier of this product can continuously output 100W x 2 power, and the speakers of 20W~200W can be pushed. It is recommended to use 8 ohm or 4 ohm speakers. Second, consider the thermal protection of the power amplifier, strengthen heat dissipation or reduce the playback volume. If multiple speakers are used in parallel, the total impedance of the speakers in parallel must be controlled at more than 4 ohms. If the impedance is too small, the power amplifier can easily enter the overcurrent protection state.
