Overview:
Welcome to use this 1x 2500W Class D audio amplifier board by Sure Electronics. It integrates high performance IRS2092 supporting Singlechannel audio amplification. The channel is capable of outputting nominal power continuously.The heatsink on board provides enough cooling for most applications, there is no need for additional heatsinking in music applications.High reliability is ensured due to extensive protection, including overtemperature,undervolatge ,over volatge,DC offset protection.It’s suitable for amplifier enthusiasts or hobbyists to finish a complete amplifier system. 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 realize high S/N ratio, low THD+N, wide frequency response range etc.
