- finished board
- fever amplifier stage or KTV amplifier, home theater multi-channel amplifier, car amplifier and battery -powered high-power amplifier ( needed boost equipment )
[Note] 1 Amplifier with overcurrent and short circuit protection , thermal protection and over-voltage protection , safe and reliable ! To improve security, the proposed increase of share speaker protection circuit , just in case.
2 high-voltage power amplifier operating in the state ( DC voltage > 60V), the inductor and the radiator will be slightly hot , if poor ventilation ( eg in a sealed box ) , should be added to enhance the cooling fan .
3 If prolonged power output , rectifier bridge requires external heat sink , the other proposes to add auxiliary cooling fan .
4 This amplifier is a dual -channel design , can be bridge .
5 amplifier board if it is installed in the speaker , it should be as far away from the speaker , the best shielding .
6 to DC power amplifier board , the board did not take the rectifier bridge, need additional rectifier bridge, and should be added to the rectifier bridge heatsink .
