Class D amplifier 6x100W @ 6ohm - TDA7498

Sure Electronics - AA-AB34181

This is a multi-channel audio amplifier board which has perfect class-D architecture and integrated TDA7498 chip to achieve 100W per channel power output. Three Class-D TDA7498s are adopted to achieve extreme efficiency. 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. Four fixed gain settings are available to allow for volume control at the source, and dual stereo RCA line-level inputs are pre-attached. Pre-drilled mounting holes work as a 2.5 mm x 5.5 mm power jack to be connected quickly. The board employs screw-down phoenix-type terminals for quick speaker wire connection.
