TDA7492 Digital Power Amplifier Board 2x50W Class D High-power Sound Speaker Amplifier Transceiver Module with Heatsink

Features: brand new and high quality The use of high-speed SMTplacement machine,over temperature reflow, the performance is very stable. With 4 model GAINparts.can auto work on different-voltage. Ultra-small 70x57mm.Comes with super output short-circuit and over-temperature over-load and prevent the impact of the switches machine. It can be used to repair and polish active speaker and improve sound quality. It can also use multi-blocks multi-channel power amplifier or 2.1 power amplifier, which has many uses. Low-price.but with high-power and good sound quality output.
