Sure Electronics AA-AB34181 6x100W TDA7498 Class-D Amplifier BoardBuild your own high-power 5.1 amplifier with this 6-channel amplifier board. Three Class-D TDA7498s are used for extreme efficiency. The small 3.6" wide by 4.8" long footprint allows this amplifier board to be used in many applications where size constraints limit the use of conventional amplifiers. Additionally, separate inputs and outputs make this amplifier board perfect for tri-amplifier use. Just add a 14 to 39 VDC power supply, signal source, and speakers!
Recommended power supply
36V 12.5A AC/DC Switching Power SupplyA low noise cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Thermal, over/under voltage, and current protection circuits are also included to extend the longevity 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. Mounting holes are provided as is a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection.
