Hello Everyone.
I want to make a 5 Speaker (FL,FR,SUB,SL,SR) amplifier with 3 LM4766T's which I got from a faulty DVD player.It wil be driven from my pc which has all sorts of outputs on it.I have some questions that need answering as I am not experienced in this area,and have not found much about this IC on this forum or the net except the datasheet.
1.Do I need a pre-amplifier or will pots/stepped attenuators do?
2.Does signal ground and power ground all go to one star point?
3.Is the star point connected to ac supply earth?
4.Do I need a Zobel network?(The amp in the DVD player had them on all outputs)
5.Does the sub amp need some kind of filter or does the PC out-put already do this?
