Eight‑way fully isolated circuit high‑power design, the peak power setting of each power supply is very large, guitar multi‑effects, pedal effects, and electric drums are all available. 4. Using fully isolated and fully independent circuit design, 2 channels of 9V, 12V, 18V output can be switched, Max current 1000mA, 6 channels of 9V 500mA output. 5. The boost line can be used to superimpose the boost output between every two channels, and can also be used to superimpose the boost output. After the boost line is superimposed, the Max output voltage can reach 36V, and the Max current can reach 2A after the boost.
