Thanks Sir Woots29

I am not sure but as far as i can recall, the 502 has an output for subwoofer but i cannot find it in your diagram or is the subwoofer output is on certain versions only?

The posted schematic diagram (input stage) doesn't matched with the actual board as posted. There are double entries of 33k/4.7k resistors & 27v zener diodes.

Sir Woots29, it is the manufacturer that maybe trying to mislead us. I still want to thank you for posting the schematic and the pictures.
