Sure Electronics AA-AB32191 2x300W TAS5630 Class-D Amplifier BoardJust one look at the power input terminals and you will know that this amplifier board means business! A Class D TAS5630 with enabled integrated feedback is used to deliver 300W to two channels, effortlessly and efficiently. This amplifier board works amazingly well with both low sensitivity speakers and subwoofers.
A robust heatsink, two-stage cooling fan, as well as protection circuits to protect against over/under voltage, over current, short circuit, and over temperature conditions are built-in for years of enjoyment. Four fixed gain settings allow you to match the amplifier to your source, and use your source as the volume control. A 25 to 50 VDC power supply is required (sold separately).
