Class D 2x400W @ 3ohm Amplifier

Sure Electronics - AA-AB32313

This audio amplifier board uses the T-AMP Sure Electronics - STA516BE technology, characterized by low distortion and low noise level. The fan works when the heat sink temperature reaches 45 degrees Celsius and stops when the temperature drops to 40 degrees Celsius.

Therefore the audible noise and the loss of inactive power carried by the fan could be omitted when the output RMS power is moderate. Recommended power supply: ALC24V6AJ.
