This AA-AB31315 1x400W audio amplifier board uses Sure Electronics' T-AMP technology, which features low distortion and low noise level. This amplifier board supports mono amplification using PBTL topology. Thanks to the dedicated heatsink design with temperature controlled fan, it is capable of delivering a maximum single channel power of 400W RMS at 3ohm without adding an additional heat sink.
In addition to the integrated chip protection, ESD and discharge protection components used throughout the amplifier board input and output ensure its robustness and reliability. Recommended power supply: ALC24V6AJ.
