Can anyone help? I am trying to run my CD/DVD player through my 4-way mixer, so have plugged phono leads out from CD, into the jack (via a small-to-large adapter) on the mixer. I lose massive sound quality (especially vocal tracks) from the CD. Yet if I unplug one of the phono leads, I get it back (but only in mono). I've tried switching leads, jack adapter, mixer input socket, etc, and the only thing I can do is keep one of the phono leads unplugged (in "CD audio out").
Any explanations / fixes?
