Description

It is a stereo amplifier board capable of delivering 125W per channel of output power into 8 Ohm load. High performance IRS2092 is integrated to support dual channel audio amplification and both of channels are capable of outputting nominal power simultaneously and continuously. The robust heatsink on board provides enough cooling for the system. A myriad of protection features such as over current, over/under voltage, over temperature protection ensures its high reliability. Resistance and capacity components of high quality, including Metallized Polyester (PET) Capacitors and lower ESR electrolytic capacitors, high performance inductors are used to gain the perfect timber, finally realizing high S/N ratio, low THD+N, wide frequency response range etc.
