Description

This mono Class D audio amplifier board can produce 750W of output power into 4 Ohm load. It integrates the high performance IRS2092 chip to achieve extreme efficiency up to 94%. The optimized heatsink design with a temperature-controlled fan provides enough cooling for most applications and eliminates your worry over heat dissipation. High reliability is ensured due to a myriad of protection features such as over current protection, over/under voltage protection, and temperature protection. 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.
