Super quality PCB. Solder pads are corrosion resistant. Soldering quality is very important in audio and high-frequency circuits. Thanks to the quality lead finishing on the Pads on the PCB, the soldering process is high quality. PCB quality greatly increases the operating performance of such circuits.
*Quad bridge 4 channel amplifier, which can deliver up to 49 watt output per channel at 4Ω.
*For this amplifier I use TDA7386 IC but you can use TDA7388 IC instead of Tda7386 IC. But if you use TDA7388 IC, you get 40 watt output per channel at 4Ω.
*This IC mostly use for high-end tv and hi-fi amplifiers. This is a class AB amplifier and have in-built output short circuit protection which is perfectly tuned for home use.
*Power Supply:- For get best performance of this amplifier, you should use 0-12V 5A-8A Transformer or 12V Battery. (Don't increase voltage).
