200 Watts True RMS Mono Amplifier Board with Inbuilt Speaker Protection

This is an audio amplifier board, which can give an output of 200 Watts RMS at 4 ohms, and it can be used in any project of active subwoofer, Active Towers, Line Array Projects. 

This is an Mono audio amplifier board, with a maximum output of 200 Watts RMS at 4 ohms + - 56VDC. This Amplifier can be used in any music system, like active subwoofer, portable line arrays, Active towers, Public address sytems. We have made inbuit rectified supply in the board, so no one needs to use bridge rectifier outside of the board. For protecting speaker in case of amplifier failure, we have used DC detected speaker protection module, which has a relay. it will disconnect speakers when detecting dc at output terminals of amplifier, so speakers would be safe. By mistake if you short speaker wires, it would go off. We have designed it based on star ground designing method, so there is no humming, and noise based on design. Amplifier gives clean output.
