The red light of the circuit is on, and the green light is on after 3-5 seconds when the circuit is normal. Circuit startup,
Maximum carrying power of 500W, midpoint potential drift of 1V, protection start
Output power: 130WX2 /8Ω; 180WX2 /4Ω
Class A amplifiers are different from ordinary amplifiers Due to working in a constant current state, even at low volume, the radiator still has a high temperature of about 50-60 degrees. Do not touch the radiator to avoid soup damage.
Users should not adjust the potentiometer on the board. To prevent excessive static current from burning out components.
The voltage of TP-11 and TP-2 should not exceed 50mv. After one hour, the temperature of the thermal bridge should not exceed 60 degrees. If any point exceeds it, the voltage of JP1/JP2 should be reduced
