Description

Class D Audio Amplifier Card 2x400W with Volume Control

Sure Electronics - AA-AB32313 KIT1

This audio amplifier board uses T-AMP Sure Electronics technology - AA-AB32313 KIT1, 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.
