Description

Class D amplifier 1x400W @ 3ohm - T-AMP

Sure Electronics - AA-AB31315

This AA-AB31315 1x400W card of the audio amplifier 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 provide a single channel maximum power from 400 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.
