This TDA8950 amplifier board has characteristics like：small size；high efficiency and high power，it adopts digital amplifier chip TDA8950 as its core, the efficiency of which can reach to 90%. TDA8950 Amplifier board can take a two-channel BTL or bridged mono modes of OCL, OCL mode output is 170W*2, BTL mode output is 300W*1,it Can establish a 2.1 power amplifier system easily.
The default delivery is connect the OCL model, connect BTL mode need you DIY connection fter receiving the product. Match: the amplifier board can be used directly as pure power amplifier You just need to plug in transformer, also can be used with tones ,or made subwoofer amplifier with low pass board, price is very high.

Product Description

1. this version can choose differential input, the effect is more good, need is equilibrium output level before to pick up.
2. the board with rectifier filter circuit, save yourself the trouble collocation rectifier filter, using 30 a new original rectifier bridge with South Korea.
Sanhe high-speed electrolytic arrays, the effect is very good.

3. bring their own trumpet protection circuit, installed substitution of DIY is more convenient.
4. Can be convenient for BTL output, need very strong beginning ability, if you don''t have a real master, please don''t try this kind of connection.

5. Reserve a plus or minus 15 v voltage potential position on board, convenient DIY ability strong buyers with myself, can give the front-end power supply.

6. Adopts SMT process，more stable than hand soldering product.
