Power:
The power amplifier adopts TPA3116 chip, the actual output power can reach 50W per channel, 2 channels total 100W (24V power supply), equipped with 12V 5A power supply. The output power is 30W*2 (4 ohms). If 8 ohm sound is connected, the output will be about 15W*2. If you need more power, you can configure the power supply by yourself. Be careful not to exceed 24V, otherwise the chip will be burned. The power supply can not be too small, because power = voltage * current, if the current power is less than 50W, there may be a power failure.
Amplifier Output:
The power amplifier is a constant resistance power amplifier, which supports 4/6/8/16 ohm passive speakers/speakers. It cannot be connected to active speakers such as computer audio, and is not suitable for passive subwoofers. The 4 pillars behind the amplifier are output interfaces, and 3.5mm headphone plugs or lotus plugs cannot be connected.
