ZK-502L Bluetooth 5.0 Wireless o Digital Power Amplifier Stereo Board 50Wx2 Bluetooth Amp Amplificador Power Amp
The potentiometer adjusts the volume with a switch for easy control of the volume, making it perfect for DIY speakers.If it is a metal box, you need to bring out the Bluetooth antenna.
The copper DC connector is used to withstand high current and no heat.Capacitor 470uf35V solid capacitors ensure power storage and heat dissipation, and stable power supply is a prerequisite for good sound quality.
Free DC head lead, compatible with the input power interface of this product, even if you don't have a DC head adapter or battery, it can be easily wired.
5.0 Bluetooth version, the transmission efficiency is higher, the transmission distance is farther.
Notes for use: the power switch on the board is standby switch, and the machine is in standby state with low power consumption after the switch is turned off. To completely turn off the power or to remove the DC plug on the machine for a long time, it is ok.

Tip: To have enough output power if the o input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please pay attention!
