Any diy hifi buffs on here?

I think what you have done is to accidentally run 2 grounds and one signal from the CD player! When you swap the '+' you are then selecting the other signal. Are you should that you shouldn't be using one '-' and both '+'? (Since the signals are AC, the + and - are a bit meaningless.)

Maybe I have that the wrong way round, but you should be able to get what I mean!

No need to thank me, the knowledge of her music pleasure is all I need

They were just fantastic to tool down the slopes of the Alps to. Ecstasy really.

Right. Each speaker has a black and a red. I am running each red to the headphone and one of the blacks. Are you saying that the black and the red are flipped for each speaker? As in the red is +ve for left and -ve fir the right?


I guess it's posdibke but it would surprise me?

Where do the CDs go?

You trim them to fit.

Ah, that makes more sense. Thought I was being stupid before.

In that case I meant try both blacks and one red for the ground.

Ok. All I've done before is switch the blacks. I'll give it a whirl and try a few combinations.

Thanks.

Spent ages tryng to find a kids CD player for our 3yo as she loves music that also has a USB port so we can give her lots of music.

Sorry, am I missing something here? Can you not give her one without a USB port, and record her all the Black Sabbath she could desire onto blank CDs?

I could do but decided its a waste to buy another. I simply assumed it woukd have one when I bught it. We didn't get the headphones until a few months later and it never occurred a socket woukd be missing. Then it was a little challenge to add one.

I applaud your efforts!

This is the kind of thing that I got into as a teenager and it eventually led to me doing a degree in Electronic Engineering. I graduated in 1986 and ...





... have barely picked up a soldering iron or designed a circuit since!

You can common the ground wires, I can even do that with my QUAD 303 poweramps.

Diesnt like it though! One speaker works well the other is quiet. Depending which bkack wire switches them around.

Erm, USB headphones?

I doubt they would work as the usb port is for reading music only rather than output.
