This is a multi-channel Class D amplifier board featuring two state-of-the-art TDA7498 ICs to achieve high efficiency up to 92%. Each channel is capable of producing up to 100W into 6 Ohm load. A low noise cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Various protection ranging from thermal, over/under voltage protection to current protection circuit ensures the longevity and durability of the amplifier board. Resistance and capacity components of high quality, including X7R ceramic capacitors and lower ESR electrolytic capacitors, are used to gain the perfect timber, finally realizing high S/N ratio, low THD +N, wide frequency response range etc.
