Default LM 4780 Noob question

So, I am nearly complete with my LM 4780 chip amp, but this is my first project! My biggest intention is simply to learn.

Once the chip amp/rectifiers are complete...can I just connect an input signal (IE: cd player) and and output signal (IE: speaker terminals), or are there other components I am missing?

Do I need a DAC or other component, or will this basic set up produce an auduble result by itself??

Thanks to all...The members on this site are aways a help.

Pretty much plug and play. You will need a volume control obviously...

But yes, once you've completed both the boards, connected them together, and add a small volume control in line with the inputs, you're ready to rock!

1 Check dc offset with a multimeter

2 If dc offset is less than around 50mv,hook up a speaker that you dont really care about(just in case)


After that you are good to go.

As sangram said "add a small volume control in line with the inputs, you're ready to rock!"
