Hi,

Please update your schematic with attached application note if any difference!

By the way this device had already EOL no recommend for new design or project.

Hi G.w. Sun:

The trouble is still about the TDA8954J, Boss had choosen the IC.So we must finish the project.

There are 4 questions：

1）the led2 flickers when it has a 4OHM load（no signal input）；

2）when output has a load(4ohm),the output wave is not so clear. the filter's parameters need to change?

3)What's your suggestions about the GND layout?

4)the crosstalk is big.

Can we contact with email?
