Most cheap Chinese made TRS to RCA cables and adapters have the colors reversed. At first I thought it was just a mistake at the factory, but then I started coming across more and more cables and adapters that were wired backwards -- to such an extent that it seems the Chinese have made up their own new standard where red = left and white (or black) = right!
Neat project. I wanted to build something like this too. Maybe I'll get around it someday. My CD-ROM has switching noise on it's headphone jack also. Didn't check the Line out but as you said there shouldn't be any noise there. Still doesn't beat the flexibility of a portable CD player and also it's features. The only advantage is really the fact that CD-ROM's are much more robust and better build than most CD players. Cheers :)
TheRAZZITEAK I did consider adding some pots, but I didn't want to run into any impedance matching issues whether I use it for low-power pre-amp signals, or high-power speaker outputs.

Would be neat to mount two logarithmic potentiometers to control the volume of each channel independently to make cross comparison even easier. :)

you should insulate the audio ground from you (metallic) project box, or use a plastic box lined with copper tape on the inside
Nice Job Eric!
Thank you!
lol, are you still rocking an embossing label maker?! :)
I am wondering how a accomplished electronic geeg ends up with such a boring project. Something seems not quiet right here.
