Power and Power??
The power amplifier adopts MA12070 chip. the actual output power can reach 68W per channel. 2 channels total 136W (20V power supply). need to be equipped with 12V5A power supply. The output power is 30W*2 (4 ohms). if connected to 8 ohm speakers. The output is about 15W*2. If you need more power. you need to configure a higher-level power supply. Be careful not to exceed 20V. otherwise the chip will be burned. and the power supply should not be too small. because power – voltage * current. if the current power If it is less than 50W. there may be a power outage.

Amplifier output:
The power amplifier is a constant resistance power amplifier. supporting passive audio/speaker of 4/6/8/16 ohms. If you cannot determine the type of speaker. please contact customer service. It cannot be connected to active audio such as computer audio. and is not suitable for passive subwoofers. The four pillars behind the power amplifier are output interfaces. which cannot be connected to 3.5mm headphone plugs or lotus plugs.
