Description

This stereo amplifier board is capable of delivering 750W per channel into 4 Ohm load. The high performance IRS2092 chip is integrated to achieve extreme efficiency up to 95% and support dual channel audio amplification to help create exceptional sounding custom multi-channel systems. It can be switched into PBTL mode to get mono 1500W. The optimized heatsink design with two temperature-controlled fans provides enough cooling for most applications and eliminates your worry over heat dissipation. Over temperature protection and over current protection increase its reliability and ensure your years of enjoyment.
