The PCB adopts a 1.6mm thick double-sided board and a 2.0 oz thick copper spray tinning process to ensure good passing performance of large and small currents. The feature of this board is the use of advanced speaker protection circuit, which effectively eliminates the impact sound of turning on and off and the DC output protection function, making your speakers safer. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the whole PCB wiring adopts one-point grounding method. Input voltage: plus or minus 30V-50V DC, AC 12V-15V (a single group, two channels in two groups). It is recommended to use +-45V.
Output power: Class A 50W+50W undistorted power, Class A and B is 250W+250W undistorted power output. The red light will be on after power on, and the green light will be on for 3-5 seconds when the circuit is normal.
