This is a dual channel Class D amplifier board featuring a state-of-the-art TDA7498 IC 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. Three fixed gain settings are available to allow for volume control at the source, and stereo RCA line-level inputs are pre-attached. Mounting holes are pre-drilled to work as a 2.5 mm x 5.5 mm power jack for quick connection. The board employs screw-down phoenix-type terminals for quick speaker wire connection.
