Description

Class D Audio Amplifier 1x300W @ 3ohm - T-AMP

Sure Electronics - AA-AB31194

Search for drivers for powerful and hi-fi subwoofers, particularly for low-impedance speakers. Here is the AA-AB31194, 1 x 300 Watt amplifier board. This audio amplifier board uses Sure Electronics T-AMP technology, characterized by low distortion and low noise level. This amplifier board supports mono amplification using the PBTL topology.

Thanks to the dedicated heat sink design with temperature controlled fan, it is able to deliver maximum single-channel power from 300 W RMS to 3ohm without extraordinary heat sink. In addition to the integrated protection of the chip, the ESD protection components used in the entire input and output of the amplifier board guarantee its robustness and reliability. Recommended power supply: ALC24V6AJ.
