The board powerful bass treble clear and melodious. TDA2030A replaced LM1875 also performed well if you want to replace the LM1875 recommended for large heat sink . TDA2030A only have five pins: positive power and negative power positive input reverse input and output. TDA2030A and negative heat sink is connected with a dual power supply heat sink and ground do not short-circuit or immediately burned TDA2030A. New board major improvements : Feature MP3 decoder board audio input pin holder ( specifications 3P-2.0mm) and to the decoder board 9V DC power supply output pin holder (2P-2.0m) Advantages of the board : 18W * 3 strong power peak up to 25W or more. High SNR almost no static noise sound super good : treble delicate soft transparent strong bass full and powerful. Circuit core three new ST TDA2030A manifold which is responsible for about two channels in addition to a subwoofer for use the use of an imported dual op amp ( large S NE5532 or Philips NE5532) do bass preamp before so powerful bass treble crisp and sweet the measured push 100W8 inch Swans speakers equally easy. The new component materials : rings precision metal film resistors monolithic capacitors polyester capacitors electrolytic capacitors connectors and power plug speaker terminals used in all 5.08 the whole process takes only a small screwdriver wiring without soldering on the circuit board it is suitable for electronics enthusiasts and audiophiles rapid improvement and maintenance of multimedia 2.1 amplifier system .
