The unique class D digital power board without LC filter can directly use the USB power supply of the computer. Double panel wiring, to properly solve the ground potential balance caused by wiring and crosstalk between channels, ultra micro design, can be easily placed in the internal small space of various digital products, with super high amplification efficiency. All adopt the machine to weld the whole plate.
