This high quality Class AB amplifier module with 4 channels is capable of developing a power of 4x50W under 4Ω, thanks to a TDA7850 chip offering what is more a rich and musical sound reproduction. The latter is mounted on a large heatsink allowing to dissipate efficiently the heat released. The input is done in 3.5mm stereo jack or XH2.54mm connectors, while the output uses screw terminals for an easy and quick assembly. The module also incorporates two potentiometers to control the volume level per pair of speakers (e.g. front and rear speakers).
