Simple amp with DC on the output...

Re: Re: Re: Re: lol lol lol lol!!!!

3. I shorted the input to ground (with the CD players output) and measured about 45mV ofset

Does it work now? 45 mV is very good!

The soundcard that clips badly is the one in this computer, not the one I am using for this new project... the clipping card is an old ISA card.. I believe it has an inbuilt amp that causes the problem..

Does it work now? 45 mV is very good!

I dunno if its 45mV it was before I connected a resistor to the input.. it wasn't a proper measurement.. (I don't think) but I can't test it again as I am working on installing it in teh case..

I wasn't going to waste my ISPs bandwith hosting these pictures.. and slowing my internet connection down... instead I chose to host them by the only website I visit, to slow that down instead.. lol

Nice, lol.
It only lacks a picture of it's face.
I like to look gear in the eyes, lol.
Where's the front panel pic?

 

[SkinnyBoy]

its just a standard CD player... nothing special at all.. well.. not from the front anyway.. and it will look like a standard CD player when finished.. (Except probably a few air holes in the top.. lol)

Looking good...maybe you might wanna consider another soundcard...

this soundcard is inbuilt.. I was talking about a different one, in a different computer.. sorry for the confusion..lol

try reducing the level of output from ur soundcard...some members here might be able to help...or maybe remove the "amp" section from the sound card...

 

[peranders]

It's possible the reduce the gain of the LM3886. Much easier

would you just shutup about the sound card.. if it makes you happy, I have swapped cards now.. happy??

well , a cd player+amps+motherboard and processor in one box

it was easier to put the amps inside the pc case , dont u think?
it looks better this way though

Ok...so you swapped the soundcards...guess the amp now works properly now ?? And no DC on the outputs...

I'm not even going to answer that, the question doesn't even make sence....

 

[li_gangyi]

I mean...does the amp work properly now?? And without DC on the outputs...

I still haven't tested it with the changes...

Just don't test it with your Grand Utopias.
