Hi Kel and Ez_bois243,
Just out of curiosity, how sure can you be that your mixer is properly filtering away any unwanted DC signals? Or are you saying that all (modern) mixers do that by default on all their inputs? Unless of course you checked your mixer specifications on that. I couldn't really rule it out on my mixer though.
Once I got to know about those DC signals, I am, being honest here :-) pissing my pants, and not daring to put anything to my mixer before let it go through a proper audio output interface, making sure that any DC components are gone.
Kind regards, Garfield.
