This is the part of my other response that was important:

Line Out on the CD player could go into Tape In on the mixer.

Headphone jack on the CD player could go into one of the mic inputs (regular channels) on the mixer, but turn the volume on the CD down to almost nothing to start.


So, which way are you connecting your CD player to the mixer, so we can know what your setup is?

There should not be a need for any other interface.

The WAV rendering process does not involve any loss of quality. Conversion to MP3 does, since that means you are compressing the file. What bit rate are you using for the MP3?
