Power and Power Supply:
The power amplifier adopts MA12070 chip, actual output power of which can reach 68W per channel and total 136W for 2 channels (20V power supply). The output power is 30W*2 (4Ω). If connected to an 8Ω speaker, the output power is about 15W*2. For more power, the user can configure the power supply. Note that the voltage of the power supply should not exceed 20V, otherwise the chip will be burned out. The voltage of the power supply cannot be too small. If the current power is less than 50W, there may be a power outage.

Amplifier Output:
The power amplifier is a constant-impedance power amplifier and supports 4Ω, 6Ω, 8Ω and 16Ω passive speakers and speakers. If you cannot determine the type of speakers, please contact customer service. It cannot be connected to active audio such as computer audio, and is not suitable for passive subwoofers. The four terminals behind the amplifier are output interfaces, which cannot be connected to 3.5mm headphone plugs or RCA plugs.
