Input levels into the mixer

[BigJD]

I think it's this one:

ART ARTcessories Zdirect Professional Passive Direct Box

Geez they sure don't give up much info on that unit.
But if I was to believe anything about it it seems that it is very much an entry level unit.
If it were me I would probably see if there was anybody about that had a better quality unit to try.
As talked about before I believe its a problem on the mixer end.

Well that does help me a good bit as far as troubleshooting is concerned, so I appreciate the input. If I manage to make any headway, I'll update with the results.

Thanks everyone for the help!
