Product Name: 2.1 channel high pass Bluetooth amplifier board 300W+300W+600W
Product Model: APTX3
Adaptable power supply:
Operating voltage range: 18-50VDC, voltage below 16V no sound. Recommended voltage: 36V-48V, current 12A or more than 12A DC power supply. [Note: DC power supply must be used, AC power is not supported!!!! Reverse positive and negative poles will burn!!!! If you use DC/DC boost module, it is recommended to adjust to 80% of the limiting voltage to avoid overshoot or ripple overvoltage resulting in module damage!!!!
Maximum power.
Left or right channel:
300W@50V, 4Ω;
160W@50V, 8Ω.
