This stereo amplifier board is capable of delivering 250W per channel into 4 Ohm load. It is based upon the Internal Rectifier AMP7D-200 reference board, using the IRS2092 amplifier IC and the IRFI4020H-117P power MOSFETThe to achieve high efficiency up to 91% and support dual channel audio amplification to help create exceptional sounding custom multi-channel systems. The robust heatsink on board provides enough cooling for most applications. Over temperature protection and over current protection increase its reliability and ensure your years of enjoyment.
